## 1. initialize / authenticate / logout + capabilities 协商（维度 1）
|
||||
|
||||
### 1.1 [major] image 能力声明与实际处理不符
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:156` (initialize -> agentCapabilities.promptCapabilities) 配合 `src/services/acp/promptConversion.ts:9-25` (promptToQueryInput)
|
||||
- 规范要求: PromptCapabilities.image (schema.json:2126-2130 + initialization.mdx:168-170): "The prompt may include ContentBlock::Image"。initialization.mdx:108 "Clients and Agents MUST treat all capabilities omitted in the initialize request as UNSUPPORTED"——反过来说,声明 `image: true` 即承诺 Client 可发送 ContentBlock::Image 且 Agent 会处理。
|
||||
- 当前实现: initialize 返回 `promptCapabilities: { image: true, embeddedContext: true }`（未声明 audio,默认 false,正确）。但 promptToQueryInput() 只处理 `type==='text'`、`'resource_link'`、`'resource'` 三类 block；`'image'` block 无对应分支,被静默丢弃。prompt() (agent.ts:269) 把整个 prompt 压成纯字符串 promptInput 传给 QueryEngine.submitMessage()。Client 若信任 `image:true` 发来图片,Agent 会完全忽略,不报错也不转换。
|
||||
- 修复建议: 二选一。
|
||||
|
||||
(A) 若确实不处理图片,把 `promptCapabilities.image` 改为 false（或删除该键,默认 false）:
|
||||
|
||||
~~~diff
|
||||
promptCapabilities: {
|
||||
- image: true,
|
||||
embeddedContext: true,
|
||||
},
|
||||
~~~
|
||||
|
||||
(B) 若要保留图片能力,在 promptToQueryInput 中处理 image block,将其作为 image content block 注入 query input（需 QueryEngine.submitMessage 支持多模态输入）:
|
||||
|
||||
~~~diff
|
||||
} else if (b.type === 'image') {
|
||||
+ const img = b as { source?: { data?: string; media_type?: string } }
|
||||
+ images.push({ data: img.source?.data, mediaType: img.source?.media_type })
|
||||
}
|
||||
~~~
|
||||
|
||||
然后扩展 submitMessage 接受 images 数组。在多模态 query input 支持完成前,推荐先采用 (A)。
|
||||
|
||||
### 1.2 [minor] sessionCapabilities.fork 为非稳定 v1 字段
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:164-169` (sessionCapabilities: { fork: {}, list: {}, resume: {}, close: {} })
|
||||
- 规范要求: 稳定 v1 SessionCapabilities (schema.json:2528-2571) 仅定义属性 `_meta` / `close` / `list` / `resume`,无 fork。SDK 自带 schema (node_modules/@agentclientprotocol/sdk/schema/schema.json:5139-5148) 明确标注 fork 为 "UNSTABLE — This capability is not part of the spec yet, and may be removed or changed at any point"。本审计只覆盖稳定 v1,draft/unstable 不在合规范围。
|
||||
- 当前实现: sessionCapabilities 中包含 `fork: {}` 以配合已实现的 `unstable_forkSession()` (agent.ts:235)。但稳定 v1 schema 的 SessionCapabilities 不认识此键。由于 schema 未设 `additionalProperties:false`,字段不会导致 schema 校验硬失败,但严格 Client 会把它当作未知扩展忽略,无法据此发现 session/fork 支持。
|
||||
- 修复建议: 将 unstable fork 能力迁移到 AgentCapabilities._meta 下的自定义扩展命名空间（与现有 `_meta.claudeCode.promptQueueing` 同模式）,符合 extensibility.mdx:111-134 "Advertising Custom Capabilities":
|
||||
|
||||
~~~diff
|
||||
agentCapabilities: {
|
||||
_meta: {
|
||||
- claudeCode: { promptQueueing: true },
|
||||
+ claudeCode: { promptQueueing: true, forkSession: true },
|
||||
},
|
||||
promptCapabilities: { image: true, embeddedContext: true },
|
||||
mcpCapabilities: { http: true, sse: true },
|
||||
loadSession: true,
|
||||
sessionCapabilities: {
|
||||
- fork: {},
|
||||
list: {},
|
||||
resume: {},
|
||||
close: {},
|
||||
},
|
||||
},
|
||||
~~~
|
||||
|
||||
### 1.3 [nit] 缺失 authMethods 字段
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:127-172` (initialize 返回值)
|
||||
- 规范要求: InitializeResponse (schema.json:1487-1548) authMethods 默认 [] (schema.json:1528-1535)。authentication.mdx:37 "Agents advertise authentication options in the authMethods field of the initialize response"。虽然默认 [] 使字段可选,但显式返回 `authMethods: []` 更利于 Client 明确判断"无需认证"而非"能力未知"。
|
||||
- 当前实现: initialize 返回值不含 authMethods 字段。authenticate() (agent.ts:176-181) 忽略 params.methodId 直接返回 `{}`,意味着即使 Client 用任意 methodId 调 authenticate 也会成功——但因 authMethods 缺失,规范上 Client 不应调用 authenticate。
|
||||
- 修复建议: 显式返回 `authMethods: []` 以明示无认证方法,与 authenticate() 的 no-op 语义一致:
|
||||
|
||||
~~~diff
|
||||
return {
|
||||
protocolVersion: 1,
|
||||
+ authMethods: [],
|
||||
agentInfo: { ... },
|
||||
agentCapabilities: { ... },
|
||||
}
|
||||
~~~
|
||||
|
||||
同时建议在 authenticate() 中校验:因未声明任何 method,若被调用应返回 method-not-found 错误（code -32601）,而非无条件成功。
|
||||
|
||||
---
|
||||
|
||||
## 2. Session 生命周期:新建 / 加载 / 恢复 / 分叉 / 列出 / 关闭（维度 2）
|
||||
|
||||
### 2.1 [critical] session/resume 重放完整历史违反 MUST NOT
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:193-199` (unstable_resumeSession) → getOrCreateSession (688-777) → replaySessionHistory (792-816) / replayHistoryMessages (757-769)
|
||||
- 规范要求: docs/protocol/session-setup.mdx "Resuming a Session": "Unlike session/load, the Agent MUST NOT replay the conversation history via session/update notifications before responding. Instead, it restores the session context, reconnects to the requested MCP servers, and returns once the session is ready to continue."
|
||||
- 当前实现: unstable_resumeSession 委托给 getOrCreateSession,这是 loadSession 使用的相同代码路径。对于在内存中找到的会话,它会调用 replaySessionHistory() (第 713 行)；对于从磁盘加载的会话,它会调用 replayHistoryMessages() (第 757-769 行)。无论哪种方式,完整的对话历史都会在返回 ResumeSessionResponse 之前通过 session/update 通知流式传输回客户端。因此 session/resume 的行为与 session/load 完全一致,违反了 MUST NOT 重放规则。
|
||||
- 修复建议: 将恢复路径与加载路径分离。添加一个不执行重放的 resumeSession() 实现:
|
||||
|
||||
~~~diff
|
||||
async unstable_resumeSession(
|
||||
params: ResumeSessionRequest,
|
||||
): Promise<ResumeSessionResponse> {
|
||||
- const result = await this.getOrCreateSession(params)
|
||||
+ const result = await this.getOrCreateSession({ ...params, replay: false })
|
||||
this.scheduleAvailableCommandsUpdate(result.sessionId)
|
||||
return result
|
||||
}
|
||||
~~~
|
||||
|
||||
在 getOrCreateSession 中,根据 `replay` 标志控制两个 replayHistoryMessages/replaySessionHistory 调用,让 resume 传递 `replay:false`（恢复时仅恢复上下文 + MCP 连接,然后立即返回 `{ modes, models, configOptions }`）。保留 loadSession 的默认 `replay:true`。
|
||||
|
||||
### 2.2 [major] session/load 跨项目 cwd 校验缺失
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:688-777` (getOrCreateSession) 和 resolveSessionFilePath in `src/utils/sessionStoragePortable.ts:401-464`
|
||||
- 规范要求: docs/protocol/session-setup.mdx "Working Directory": "This directory MUST be an absolute path MUST be used for the session regardless of where the Agent subprocess was spawned."
|
||||
- 当前实现: createSession() 从 {cwd, mcpServers} 计算 sessionFingerprint (agent.ts:665-670),而 getOrCreateSession() 仅在请求的会话已驻留在 this.sessions (第 696-721 行) 时才将指纹与该内存中的会话进行比较。当会话不在内存中时（正常的恢复/加载情况）,代码会调用 resolveSessionFilePath(sessionId, cwd),该方法会搜索请求的目录、其 git 工作树,最后扫描所有项目目录 (sessionStoragePortable.ts:410-463)。没有任何检查验证会话原始的 cwd 是否与请求的 cwd 匹配。客户端可以传入项目 A 的 cwd 并成功加载项目 B 下持久化的会话,然后运行一个上下文错误的会话。在基于磁盘的路径上从未计算或比较过指纹。
|
||||
- 修复建议: 在解析文件路径后,从磁盘上的会话中读取原始的 cwd（第一条消息的 'cwd' 字段）,并将其与请求的 cwd 进行比较。如果不匹配,返回错误（JSON-RPC 错误代码 -32602 无效参数）:
|
||||
|
||||
~~~ts
|
||||
const resolved = await resolveSessionFilePath(params.sessionId, params.cwd)
|
||||
if (resolved) {
|
||||
const lite = await readSessionLite(resolved.filePath)
|
||||
const originalCwd = lite && extractJsonStringField(lite.head, 'cwd')
|
||||
if (originalCwd && path.resolve(originalCwd) !== path.resolve(params.cwd)) {
|
||||
throw new RpcError(-32602, `Session cwd mismatch: session belongs to ${originalCwd}, requested ${params.cwd}`)
|
||||
}
|
||||
}
|
||||
~~~
|
||||
|
||||
或者,在加载会话的 cwd 不同时跳过工作树/全目录回退搜索,以便跨项目加载自然失败。
|
||||
|
||||
### 2.3 [major] unstable_forkSession 忽略源会话 ID,创建空白会话
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:235-245` (unstable_forkSession)
|
||||
- 规范要求: schema/schema.unstable.json ForkSessionRequest: required = ["sessionId", "cwd"]；描述为 "The ID of the session to fork."。Agent 在 initialize (agent.ts:165) 中通过 `sessionCapabilities.fork:{}` 声称支持分叉。
|
||||
- 当前实现: unstable_forkSession 忽略了 params.sessionId（要分叉的源会话）和 params.additionalDirectories。它只是调用 `this.createSession({ cwd, mcpServers, _meta })` 来构建一个全新的空会话,与源会话没有任何共享的历史/上下文。一个本应从源会话上下文分支出来的 "fork" 实际上创建了一个空白会话。新会话的 ID 被返回,但源会话的对话未恢复,因此分叉在功能上是错误的。
|
||||
- 备注: 尽管 fork 是 UNSTABLE 且超出了严格的 v1 合规范围,但 Agent 声明了该能力并注册了处理程序,因此客户端调用 `session/fork` 将获得语义错误的结果。
|
||||
- 修复建议: 将源会话的消息加载到内存中（通过 getLastSessionLog(params.sessionId)）,并将它们作为 initialMessages 传递给 createSession,同时转发 additionalDirectories:
|
||||
|
||||
~~~ts
|
||||
async unstable_forkSession(params: ForkSessionRequest): Promise<ForkSessionResponse> {
|
||||
let initialMessages: Message[] | undefined
|
||||
try {
|
||||
const log = await getLastSessionLog(params.sessionId as UUID)
|
||||
if (log?.messages.length) initialMessages = deserializeMessages(log.messages)
|
||||
} catch (err) { console.error('[ACP] fork source load failed:', err) }
|
||||
const response = await this.createSession(
|
||||
{ cwd: params.cwd, mcpServers: params.mcpServers ?? [], _meta: params._meta, additionalDirectories: params.additionalDirectories },
|
||||
{ initialMessages },
|
||||
)
|
||||
this.scheduleAvailableCommandsUpdate(response.sessionId)
|
||||
return response
|
||||
}
|
||||
~~~
|
||||
|
||||
（扩展 createSession 签名以接受并持久化 additionalDirectories。）
|
||||
|
||||
### 2.4 [minor] listSessions 静默截断为 100 并忽略 cursor 分页
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:211-231` (listSessions) 和 `src/utils/listSessionsImpl.ts:439-454`
|
||||
- 规范要求: docs/protocol/session-list.mdx "Pagination": "Clients MUST treat cursors as opaque tokens ... Agents SHOULD return an error if the cursor is invalid." ListSessionsRequest.cursor 是一个可选的不透明分页 token (schema.json:1597)。
|
||||
- 当前实现: listSessions 完全忽略了 params.cursor。它调用 `listSessionsImpl({ dir: params.cwd ?? undefined, limit: 100 })`——一个硬编码的 100 条目上限,没有偏移量,也没有消费 cursor。响应从不返回 nextCursor,因此跨大历史记录的分页静默失败:拥有超过 100 个会话的客户端只能看到最近的 100 个,无法获取其余的。无效的 cursor 被静默接受（规范指出 Agent 应该报错）。虽然返回不带 nextCursor 的所有结果是允许的,但静默截断为 100 违反了 "Clients MUST treat a missing nextCursor as the end" 的契约,因为 Agent 实际上有更多结果却隐瞒了。
|
||||
- 修复建议: 要么 (a) 完全去掉硬编码的 100 限制（如果没有更多结果,返回所有会话且不带 nextCursor 是合规的）,或者 (b) 实现 cursor→offset 解码:
|
||||
|
||||
~~~ts
|
||||
const decoded = params.cursor
|
||||
? JSON.parse(Buffer.from(params.cursor, 'base64').toString())
|
||||
: { offset: 0 }
|
||||
const candidates = await listSessionsImpl({ dir: params.cwd, limit: PAGE_SIZE, offset: decoded.offset })
|
||||
const nextCursor = candidates.length === PAGE_SIZE
|
||||
? Buffer.from(JSON.stringify({ offset: decoded.offset + PAGE_SIZE })).toString('base64')
|
||||
: undefined
|
||||
return { sessions: [...], nextCursor }
|
||||
~~~
|
||||
|
||||
至少,当客户端发送 params.cursor 时（因为分页未实现）,返回一个错误,这样客户端就不会得到静默错误的结果。
|
||||
|
||||
### 2.5 [nit] listSessions 对无标题会话发出空字符串 title
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:219-228` (listSessions 会话映射)
|
||||
- 规范要求: schema.json SessionInfo (2787): title 是 type `["string","null"]`（可选,可为空）。docs/protocol/session-list.mdx: "Human-readable title for the session. May be auto-generated from the first prompt."
|
||||
- 当前实现: 对于每个候选者,代码无条件地发出 `title: sanitizeTitle(candidate.summary ?? '')`。当会话没有可提取的摘要/标题时（边缘情况下 candidate.summary 为空字符串）,Agent 发出 `title: ""`。空字符串技术上是有效的,但没有信息量；根据 schema,省略 title 会更清晰。这是一个表面问题,因为基于磁盘的候选者很少幸存于空摘要。
|
||||
- 修复建议: 仅在非空时包含 title:
|
||||
|
||||
~~~diff
|
||||
+ const title = sanitizeTitle(candidate.summary ?? '')
|
||||
sessions.push({
|
||||
sessionId: candidate.sessionId,
|
||||
cwd: candidate.cwd,
|
||||
- title: sanitizeTitle(candidate.summary ?? ''),
|
||||
+ ...(title ? { title } : {}),
|
||||
updatedAt: new Date(candidate.lastModified).toISOString(),
|
||||
})
|
||||
~~~
|
||||
|
||||
updatedAt 的 ISO 8601 格式（new Date(ms).toISOString() → 例如 '2025-10-29T14:22:15.123Z') 已经合规。
|
||||
|
||||
### 2.6 [nit] NewSessionResponse 不含 cwd,但规范本身不要求
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:185-189` (newSession) → createSession 返回 675-680
|
||||
- 规范要求: schema.json NewSessionResponse (1916) 要求仅 `['sessionId']`；cwd 不在响应模式中。
|
||||
- 当前实现: newSession 返回 `{ sessionId, models, modes, configOptions }`。sessionId（唯一必填字段）存在。cwd 不返回,但 schema 从未要求在响应中返回 cwd（cwd 是 session/new 的请求侧输入,如 docs/protocol/session-setup.mdx 第 52-68 行示例响应第 77-80 行所示,仅返回 `{ sessionId }`）。因此相对于规范没有违规；记录此内容以解决审计检查清单中的错误前提。
|
||||
- 修复建议: 无需代码更改。只需更新内部审计检查清单,停止期望在 NewSessionResponse 中有 cwd。
|
||||
|
||||

|
||||
|
||||
## 3. session/prompt + session/cancel + stop reason + usage（维度 3）
|
||||
|
||||
### 3.1 [critical] image 能力声明与实际丢弃不符
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:155-158` (initialize) + `src/services/acp/promptConversion.ts:9-25` (promptToQueryInput)
|
||||
- 规范要求: PromptRequest.prompt is ContentBlock[]；Clients MUST restrict content types according to PromptCapabilities (prompt-turn.mdx:89-98)。Agent advertises `promptCapabilities.image: true`, signalling it accepts image content blocks.
|
||||
- 当前实现: initialize() 声明 `promptCapabilities: { image: true, embeddedContext: true }`,但 promptToQueryInput() 只处理 block types `'text'`、`'resource_link'`、`'resource'`。任何 `type: 'image'` block（以及任何非文本/非资源 block）被静默丢弃——只产生字符串连接的文本,所以 image 输入无警告消失。没有通过文件系统或错误暴露 image 的回退。
|
||||
- 修复建议: 要么停止宣告 image 支持直到它被接通,要么扩展 promptToQueryInput 以暴露 image block。最小正确修复:
|
||||
|
||||
~~~diff
|
||||
promptCapabilities: {
|
||||
- image: true,
|
||||
+ image: false,
|
||||
embeddedContext: true,
|
||||
},
|
||||
~~~
|
||||
|
||||
如果打算 image passthrough,query input 必须携带 image 数据——例如返回一个结构化输入,携带 `{ type: 'image', source: {...} }` block 而不是 flat string。在此之前,能力声明是协议谎言,使客户端发送 agent 永远看不到的 image。此问题与维度 1 的 §1.1 同根因。
|
||||
|
||||
### 3.2 [major] PromptResponse.usage 为非规范根字段
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:326-340` (prompt return) 和 `src/services/acp/bridge.ts:756,1059` (forwardSessionUpdates return type)
|
||||
- 规范要求: Stable v1 schema: PromptResponse (schema/schema.json:2163-2184) 只定义 `stopReason`（必填）和 `_meta`（可选）。extensibility.mdx:39 states: "Implementations MUST NOT add any custom fields at the root of a type that's part of the specification. All possible names are reserved for future protocol versions." `usage`/`TokenUsage` does not exist anywhere in the stable schema。
|
||||
- 当前实现: prompt() 返回 `{ stopReason, usage: { inputTokens, outputTokens, cachedReadTokens, cachedWriteTokens, totalTokens } }`。`usage` 是非规范根字段。它碰巧匹配 bundled SDK schema (schema.json:4656-4665 marked **UNSTABLE**) 中的 UNSTABLE 形状,但那超出了 v1 合规范围。
|
||||
- 修复建议: 停止为 v1 合规性在 PromptResponse 上发出 `usage`,或将其置于能力协商之后。最干净的修复:
|
||||
|
||||
~~~diff
|
||||
-return { stopReason, usage }
|
||||
+return { stopReason }
|
||||
~~~
|
||||
|
||||
如果需要 token 报告,通过现有的 `usage_update` SessionUpdate 发送（已在 bridge.ts:843-854 完成,见维度 4 的 critical finding——但 usage_update 本身也是非稳定的）和/或将其移至 `_meta`——但根据 extensibility.mdx:39,即使是未知的根键也被保留,因此唯一规范一致的位置是 `_meta.usage`。推荐:
|
||||
|
||||
~~~ts
|
||||
return { stopReason, _meta: usage ? { claudeCode: { usage } } : undefined }
|
||||
~~~
|
||||
|
||||
### 3.3 [major] Anthropic refusal stop_reason 被误报为 end_turn
|
||||
|
||||
- 位置: `src/services/acp/bridge.ts:866-876` (success case stop_reason mapping)
|
||||
- 规范要求: StopReason enum (schema.json:3212-3241) includes `refusal`——"The turn ended because the agent refused to continue." prompt-turn.mdx:278 defines refusal as a first-class stop reason。Anthropic API can return `stop_reason: 'refusal'` on safety refusals。
|
||||
- 当前实现: 在 `success` 情况下只映射了 `'max_tokens'`；其他所有 Anthropic stop_reason（包括 `'refusal'`、`'end_turn'`、`'stop_sequence'`、`'tool_use'`）都落入默认 `stopReason = 'end_turn'`。没有分支将 `'refusal'` 映射到 ACP `refusal` stop reason,因此真正的拒绝被误报为成功的 end_turn,破坏了规范契约——refusal 应被反映（根据 refusal 语义,prompt 不应包含在下一轮）。
|
||||
- 修复建议: 添加显式映射:
|
||||
|
||||
~~~diff
|
||||
case 'success': {
|
||||
- const stopReasonStr = msg.stop_reason
|
||||
- if (stopReasonStr === 'max_tokens') {
|
||||
- stopReason = 'max_tokens'
|
||||
- }
|
||||
- if (isError) {
|
||||
- // Report error as end_turn
|
||||
- stopReason = 'end_turn'
|
||||
- }
|
||||
+ const r = msg.stop_reason
|
||||
+ if (r === 'max_tokens') stopReason = 'max_tokens'
|
||||
+ else if (r === 'refusal') stopReason = 'refusal'
|
||||
+ else stopReason = 'end_turn'
|
||||
+ if (isError) stopReason = 'end_turn'
|
||||
break
|
||||
}
|
||||
~~~
|
||||
|
||||
### 3.4 [minor] max_tokens 与 isError 检查相互覆盖
|
||||
|
||||
- 位置: `src/services/acp/bridge.ts:866-876` (success case) 和 877-886 (error_during_execution case)
|
||||
- 规范要求: StopReason `max_tokens` (schema.json:3221-3223): "The turn ended because the agent reached the maximum number of tokens." prompt-turn.mdx:271-272。
|
||||
- 当前实现: `max_tokens` 检查和 `isError` 检查是两个独立的 `if` 语句,不是 `else if`。当 `stop_reason === 'max_tokens'` 且 `isError === true` 时,第一个 `if` 设置 `stopReason = 'max_tokens'`,但第二个 `if` 立即覆盖为 `end_turn`。同样的缺陷也出现在 error_during_execution (877-886):max_tokens 可能被设置然后被覆盖。SDK 标记为错误的 max-tokens 终止因此被报告为 end_turn,向客户端隐藏了真正的原因。
|
||||
- 修复建议: 使分支互斥或将 isError 仅作为回退（见 §3.3 的合并修复 diff）。
|
||||
|
||||
### 3.5 [minor] prompt 未读取 params._meta,trace context 丢失
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:262-287` (prompt queue handling) 和 269 (params._meta not read)
|
||||
- 规范要求: extensibility.mdx:8-39——`_meta` 是每个类型的保留扩展点,包括 PromptRequest (schema.json:2137-2141)。W3C trace context keys (`traceparent`、`tracestate`、`baggage`) SHOULD be propagated for OpenTelemetry interop (extensibility.mdx:33-38)。prompt-queue feature 只在 agentCapabilities 级别宣告（agent.ts:150-154 `_meta.claudeCode.promptQueueing: true`) 是正确的地方。
|
||||
- 当前实现: prompt() 从不读取 `params._meta`。两个后果: (1) prompt 中客户端提供的 W3C trace context (`traceparent`/`tracestate`/`baggage`) 被静默丢弃,破坏了 tracing interop；(2) prompt-queueing 扩展已宣告,但没有 per-request opt-out 机制——客户端无法通过 `_meta` 信号 skip-queue。能力宣告本身是合规的。
|
||||
- 修复建议: 将 `params._meta` 传递给 query 层,以便 trace context 可以附加到下游 API 调用,并可选地遵守 `_meta.claudeCode.skipQueue` flag。至少,转发 traceparent:
|
||||
|
||||
~~~ts
|
||||
const traceparent = params._meta?.traceparent
|
||||
// thread it into the API client request headers
|
||||
~~~
|
||||
|
||||
### 3.6 [minor] prompt catch 块对 abort 信号竞态返回错误而非 cancelled
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:342-359` (prompt catch block)
|
||||
- 规范要求: prompt-turn.mdx:304-311 (Warning): "Agents MUST catch these errors and return the semantically meaningful `cancelled` stop reason, so that Clients can reliably confirm the cancellation." 这适用于中止操作产生的错误。当 session.cancelled 为 true 时,catch 块必须为任何错误返回 cancelled。
|
||||
- 当前实现: catch 块确实检查 `if (session.cancelled) return { stopReason: 'cancelled' }` (343-345)——对于进程内 cancelled flag 是正确的。然而,守卫使用 `session.cancelled`,只由 cancel() 设置。如果 QueryEngine 的 abort signal 通过 interrupt() 触发,但 session.cancelled 尚未设置（interrupt() 完成和 cancel() 到达第 379 行之间的竞态窗口）,或从嵌套路径传播取消派生的 AbortError,条件为 false,错误被重新抛出为 JSON-RPC 错误而不是 cancelled stop reason。更稳健的信号是 abort signal 本身。
|
||||
- 修复建议: 在 flag 之外检查 abort signal,并将 AbortError/abort 形状错误视为取消:
|
||||
|
||||
~~~ts
|
||||
} catch (err) {
|
||||
const isAbort = err instanceof Error && (
|
||||
err.name === 'AbortError' || /abort|cancelled|interrupt/i.test(err.message)
|
||||
)
|
||||
if (session.cancelled || isAbort) {
|
||||
return { stopReason: 'cancelled' }
|
||||
}
|
||||
// ...existing process-death + rethrow
|
||||
}
|
||||
~~~
|
||||
|
||||
### 3.7 [minor] 空 prompt 提前返回 end_turn 语义错误
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:271-273` (empty prompt early return)
|
||||
- 规范要求: prompt-turn.mdx:185-199——Agent MUST respond to session/prompt with a StopReason when the turn ends。schema 没有定义空 prompt 的行为；StopReason `end_turn` (schema.json:3216-3218) 描述为 "The turn ended successfully," 暗示实际模型处理已发生。
|
||||
- 当前实现: `if (!promptInput.trim()) return { stopReason: 'end_turn' }` 在不调用模型的情况下返回 end_turn。语义上,这为 no-op 输入报告成功的 turn,这是误导性的:模型从未运行。也没有路径区分 "空 prompt 无效" 和 "turn 完成"。
|
||||
- 修复建议: 要么拒绝空 prompt 与 JSON-RPC 错误（invalid_params, -32602）,因为 `prompt` 是必需的 ContentBlock[] 而有效空消息可能是畸形的,或至少文档说明 end_turn 在这里意味着 "nothing to do"。优先抛出:
|
||||
|
||||
~~~diff
|
||||
-if (!promptInput.trim()) return { stopReason: 'end_turn' }
|
||||
+if (!promptInput.trim()) throw new RpcError(-32602, 'Prompt content is empty')
|
||||
~~~
|
||||
|
||||
### 3.8 [nit] usage 对象缺少 thoughtTokens
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:328-339` (usage object construction)
|
||||
- 规范要求: Bundled (UNSTABLE, out of v1 scope) SDK Usage (node_modules/@agentclientprotocol/sdk/schema/schema.json:6750-6791) has required `totalTokens/inputTokens/outputTokens` and optional `cachedReadTokens`、`cachedWriteTokens`、`thoughtTokens`。Stable v1 has no Usage at all。
|
||||
- 当前实现: 构造的 usage 对象省略 `thoughtTokens`（reasoning/thinking tokens）。对于发出 reasoning tokens 的模型,报告的 totalTokens (input+output+cachedRead+cachedWrite) 将低估实际计费 tokens,因为 thinking tokens 被排除在总和之外。
|
||||
- 修复建议: 如果报告 usage（见 §3.2 extra-field finding）,包括可用的 thinking tokens:
|
||||
|
||||
~~~ts
|
||||
totalTokens: inputTokens + outputTokens + cachedReadTokens + cachedWriteTokens + thoughtTokens
|
||||
~~~
|
||||
|
||||
注意,这只在 unstable contract 下重要；对于严格的 v1 合规性,整个 usage 字段应被移除。

## 4. session/update 通知形状（所有 update 变体）（维度 4）
|
||||
|
||||
### 4.1 [critical] usage_update 非稳定 v1 SessionUpdate 判别器 🔶 已撤销原修复 (2026-06-19)
|
||||
|
||||
- 位置: `src/services/acp/bridge/forwarding.ts` (forwardSessionUpdates, 'result' 情况)
|
||||
- 规范要求: ACP v1 稳定版 schema schema.json:2942-3108 定义 SessionUpdate 为通过 propertyName `sessionUpdate` 进行 oneOf 判别,包含 10 个有效常量: `user_message_chunk`、`agent_message_chunk`、`agent_thought_chunk`、`tool_call`、`tool_call_update`、`plan`、`available_commands_update`、`current_mode_update`、`config_option_update`、`session_info_update`。`usage_update` 不在 v1 稳定版规范中。（Claude Code 捆绑的 SDK schema v0.19.0 第 5789 行将其标记为 "UNSTABLE——此功能尚未包含在规范中,随时可能被删除或更改"。）
|
||||
- **决策回滚**: 原修复（2026-06-19 早期）完全移除了 `usage_update` 以追求严格 v1 stable 合规。但现实中所有主流 ACP 客户端（Zed、Cursor 等）实现的是 unstable spec,移除 `usage_update` 后客户端 context 使用量一律显示 `0/0`,严重破坏 UX。鉴于:
|
||||
- SDK 已包含 `UsageUpdate` 类型(`sessionUpdate: 'usage_update'`, 字段 `used` + `size` + 可选 `cost`)
|
||||
- `PromptResponse.usage` 也已由 SDK 在根部支持(UNSTABLE 但被广泛实现)
|
||||
- 这是 context 使用量报告的**唯一**标准化载体
|
||||
|
||||
现行实现选择**优先保证 interop**: 在 'result' 消息后发送 `usage_update`,并在 PromptResponse 根部填充 `usage`。同时保留 `_meta.claudeCode.usage` 作为厂商扩展命名空间下的镜像,以便消费者任选读取路径。
|
||||
- 当前实现: `bridge/forwarding.ts` 在收到 'result' 消息且 `lastAssistantTotalUsage !== null` 时发出 `usage_update`:
|
||||
- `used` = 最近一条 assistant 消息的 input + output + cache_read + cache_creation token 总和（≈ 当前上下文占用）
|
||||
- `size` = `lastContextWindowSize`（默认 200000，通过 modelUsage prefix-match 解析）
|
||||
- compact_boundary 时不发（不知道压缩后的实际占用；下一轮的 result 会自然修正）
|
||||
- 同步调整: `agent/promptFlow.ts` 在 PromptResponse 根部添加 `usage: { totalTokens, inputTokens, outputTokens, thoughtTokens, cachedReadTokens, cachedWriteTokens }`,并镜像到 `_meta.claudeCode.usage`。
|
||||
|
||||
### 4.2 [minor] 从未发出 tool_call in_progress 状态 ✅ 已修复 (2026-06-19)
|
||||
|
||||
- 位置: `src/services/acp/bridge.ts` `toAcpNotifications` 的 `tool_use` 分支 alreadyCached 路径
|
||||
- 规范要求: schema.json:3525-3548 ToolCallStatus 枚举为 `pending`、`in_progress`、`completed`、`failed`。tool-calls.mdx:76-91 ('Updating') 文档化了一个生命周期,其中 Agent 在工具实际运行时报告 `status: 'in_progress'`。v1 规范称工具 "在其生命周期中会经历不同状态"。
|
||||
- 修复: 当同一 tool_use 块被第二次遇到时(streaming `content_block_start` 首次 + assistant 完整消息回放第二次),发 `tool_call_update` with `status: 'in_progress'`。此时语义为"input 已收齐,即将执行"。完整 ToolCallStatus 生命周期现在是 pending → in_progress → completed|failed。
|
||||
- 修复建议: 当 Claude Code 知道工具开始执行时,发出一个中间的 tool_call_update:
|
||||
|
||||
~~~ts
|
||||
{ sessionUpdate: 'tool_call_update', toolCallId, status: 'in_progress' }
|
||||
~~~
|
||||
|
||||
如果无法获得执行挂钩,请记录此差距；规范将其定义为 SHOULD 级别的生命周期信号,因此省略它仅属于轻微的合规性缺失。
|
||||
|
||||
### 4.3 [minor] 从未通过 session/update 发出 session_info_update
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:225-226` (session-list 候选构建)——src/services/acp/ 下没有任何位置发出 session_info_update
|
||||
- 规范要求: schema.json:2819-2837 SessionInfoUpdate 是一个有效的 SessionUpdate 变体 (`sessionUpdate: 'session_info_update'`),包含可选字段 `title` 和 `updatedAt`。它允许 Agent 通知客户端动态会话标题和最后活动时间戳。
|
||||
- 当前实现: agent.ts 计算了一个会话标题（`title: sanitizeTitle(candidate.summary ?? '')` 和 `updatedAt: new Date(candidate.lastModified).toISOString()`)——但这仅用于 session/list 响应负载。从不通过 `session/update` 通知向客户端发出 session_info_update,因此当前会话的标题/更新时间永远不会流式传输给客户端。
|
||||
- 修复建议: 当派生出或更改会话标题时（例如,在第一次助手回复或摘要提取后）,发出:
|
||||
|
||||
~~~ts
|
||||
await this.conn.sessionUpdate({
|
||||
sessionId,
|
||||
update: { sessionUpdate: 'session_info_update', title: derivedTitle, updatedAt: new Date().toISOString() },
|
||||
})
|
||||
~~~
|
||||
|
||||
这通过 v1 稳定版规范中记录的通道,为客户端提供了规范的会话显示名称。
|
||||
|
||||
### 4.4 [nit] Bash 工具 _meta 键未命名空间化 ✅ 已修复 (2026-06-19,与 §5.2 合并)
|
||||
|
||||
- 位置: `src/services/acp/bridge.ts` `toolUpdateFromToolResult` Bash 分支
|
||||
- 规范要求: schema.json 将 `_meta` 记录为保留的扩展点（"实现不得对这些键上的值做出假设"）。建议使用反向 DNS / 供应商命名空间的自定义键。
|
||||
- 修复: 与 §5.2 合并处理 — 完全删除了 `terminal_info` / `terminal_output` / `terminal_exit` 三个非标准 `_meta` 键,以及伪造的 `terminalId`。Bash 工具结果现在统一走 inline `{type:'text'}` content,不再向 `_meta` 注入任何键。命名空间问题随之消失。

||||

## 5. tool calls + permissions delegation（维度 5）
|
||||
|
||||
### 5.1 [major] terminal 能力检测误用 _meta 而非 clientCapabilities.terminal
|
||||
|
||||
- 位置: `src/services/acp/permissions.ts:280-285` (checkTerminalOutput)
|
||||
- 规范要求: ClientCapabilities schema (schema.json:586-613) defines the standard terminal capability as the boolean field `clientCapabilities.terminal` (line 606-610, default false)。Terminals doc (docs/protocol/terminals.mdx:8-25) states: "Before attempting to use terminal methods, Agents MUST verify that the Client supports this capability by checking ... `clientCapabilities.terminal`"。`_meta` is explicitly reserved and "Implementations MUST NOT make assumptions about values at these keys" (schema.json:1961)。
|
||||
- 当前实现: checkTerminalOutput 读取 `clientCapabilities._meta.terminal_output === true` 来决定 terminal 支持。从未咨询标准 `clientCapabilities.terminal` 布尔值,因此宣告 `terminal: true`（没有 Claude-Code 特定 `_meta.terminal_output` flag）的合规 ACP 客户端被视为不支持 terminals,而保留的 `_meta` 字段被视为真正的能力。
|
||||
- 修复建议: 将标准能力作为主要,仅对较旧的 Claude-Code 客户端的遗留 `_meta` flag 进行回退:
|
||||
|
||||
~~~ts
|
||||
function checkTerminalOutput(clientCapabilities?: ClientCapabilities): boolean {
|
||||
if (!clientCapabilities) return false
|
||||
if (clientCapabilities.terminal === true) return true
|
||||
// Legacy Claude-Code clients advertised via _meta before terminal: bool existed
|
||||
const meta = (clientCapabilities as unknown as Record<string, unknown>)._meta
|
||||
return !!meta && typeof meta === 'object' && (meta as Record<string, unknown>)['terminal_output'] === true
|
||||
}
|
||||
~~~
|
||||
|
||||
### 5.2 [major] terminal 生命周期未实现,伪造 terminalId 且 _meta 注入非标准键 — 🔶 简化版已修复 (2026-06-19),完整版待办
|
||||
|
||||
- 位置: `src/services/acp/bridge.ts` `toolUpdateFromToolResult` Bash 分支 + `toolInfoFromToolUse` Bash 分支
|
||||
- 规范要求: Terminals doc (docs/protocol/terminals.mdx:27-110) defines the standard terminal lifecycle: the Agent MUST call `terminal/create` to obtain a real `terminalId`, embed it via ToolCallContent `{type:'terminal', terminalId}` (schema.json:3242-3256), and the Client retrieves output via `terminal/output`。ToolCallUpdate._meta is reserved: "Implementations MUST NOT make assumptions about values at these keys" (schema.json:3555)。
|
||||
- 简化版修复（已落地）: 按文档建议回退到 inline `{type:'text'}` content,删除了伪造的 `terminalId: toolUse.id`（toolInfoFromToolUse + toolUpdateFromToolResult 两处）和三个非标准 `_meta` 键（`terminal_info` / `terminal_output` / `terminal_exit`）。合规客户端不再被误导去查找不存在的 terminal。Bash 输出仍以 ```console 围栏文本形式呈现给客户端。
|
||||
- 完整版（待办）: 实现标准 terminal 流程,需要 BashTool 接入 PTY 子系统:在工具运行前调用 `conn.request('terminal/create', {sessionId, command, cwd, outputByteLimit})`,嵌入返回的真实 `terminalId` 到 ToolCallContent,通过 terminal 子系统流式输出,完成时 `terminal/release`。此改造涉及 BashTool 执行管线（影响 CLI REPL 路径）,需单独决策是否仅 ACP 路径启用。
|
||||
|
||||
### 5.3 [major] cancelled 权限结果被当作普通拒绝
|
||||
|
||||
- 位置: `src/services/acp/permissions.ts:136-142` (createAcpCanUseTool cancelled branch) 和 231-237 (handleExitPlanMode cancelled branch)
|
||||
- 规范要求: RequestPermissionOutcome.cancelled variant (schema.json:2310-2320) is sent by the Client "when a client sends a session/cancel notification to cancel an ongoing prompt turn"。tool-calls.mdx:168-186 and the schema description state the prompt turn was cancelled。When the prompt turn is cancelled the Agent MUST resolve session/prompt with `StopReason::Cancelled` (schema.json:629 "Respond to the original session/prompt request with StopReason::Cancelled")。
|
||||
- 当前实现: 在 `outcome === 'cancelled'` 时,canUseTool 返回一个通用的 `PermissionDenyDecision`（`behavior:'deny'`、decisionReason mode default / plan）。这作为普通拒绝反馈到工具执行器,因此 turn 继续（或失败与普通的 end_turn / tool-error）而不是用 `cancelled` 中止 turn。agent.cancel() flag 从不响应 cancelled 权限结果设置,因此 prompt 循环不返回 stopReason 'cancelled' 仅因为用户/客户端取消了权限 prompt。
|
||||
- 修复建议: 将 `cancelled` 结果视为 turn-cancellation 信号。从 canUseTool 抛出一个类型化的 sentinel（或通过闭包传递一个 session-level cancelled flag）并让 forwardSessionUpdates / agent.prompt() 检测它以返回 `{stopReason:'cancelled'}`:
|
||||
|
||||
~~~ts
|
||||
if (response.outcome.outcome === 'cancelled') {
|
||||
cancelledRef.cancelled = true // shared with agent.cancel()
|
||||
session.queryEngine.interrupt()
|
||||
return { behavior:'deny', message:'Permission request cancelled by client', decisionReason:{type:'mode', mode:'default'}, toolUseID }
|
||||
}
|
||||
~~~
|
||||
|
||||
并在 agent.prompt(): `if (session.cancelled) return { stopReason: 'cancelled' }`。
|
||||
|
||||
### 5.4 [minor] 从未提供 reject_always 权限选项
|
||||
|
||||
- 位置: `src/services/acp/permissions.ts:123-127` (options array)
|
||||
- 规范要求: PermissionOptionKind enum (schema.json:1992-2016) defines four variants: `allow_once`、`allow_always`、`reject_once`、`reject_always`。tool-calls.mdx:200-208 lists the same four。
|
||||
- 当前实现: 提供的标准权限选项只有三个: `allow_always`、`allow_once`、`reject_once`。`reject_always`（"Reject this operation and remember the choice"）从不提供,因此用户无法通过协议的预期机制持久化拒绝（客户端依赖此 hint 显示 "remember" 复选框以供拒绝）。
|
||||
- 修复建议: 添加一个 reject_always 选项,以便四个规范选择可用:
|
||||
|
||||
~~~ts
|
||||
const options: PermissionOption[] = [
|
||||
{ kind:'allow_always', name:'Always Allow', optionId:'allow_always' },
|
||||
{ kind:'allow_once', name:'Allow', optionId:'allow' },
|
||||
{ kind:'reject_once', name:'Reject', optionId:'reject' },
|
||||
{ kind:'reject_always', name:'Always Reject', optionId:'reject_always' },
|
||||
]
|
||||
~~~
|
||||
|
||||
并在 selected 分支中处理 `optionId === 'reject' || optionId === 'reject_always'`。
|
||||
|
||||
### 5.5 [minor] ToolCallLocation.path / Diff.path 未归一化为绝对路径
|
||||
|
||||
- 位置: `src/services/acp/bridge.ts:251` (Read locations), 278/300 (Write/Edit locations), 314 (Glob locations), 700 (toolUpdateFromEditToolResponse locations)
|
||||
- 规范要求: ToolCallLocation.path (schema.json:3517-3519) is "The file path being accessed or modified" (string)。tool-calls.mdx:304-306 and the protocol-wide path rule require absolute paths；Diff.path (schema.json:1178-1181) and the docs example ('/home/user/project/src/main.py') also use absolute paths。The ACP spec states all file paths MUST be absolute。
|
||||
- 当前实现: Locations 和 diff paths 直接从 tool input（`input.file_path`、`input.path`、`response.filePath`）填充,不归一化为绝对路径。如果模型（或重放）提供相对路径或具有未解析的 `~`/`.` 段的路径,则发出的 ToolCallLocation.path / Diff.path 将是相对的,违反绝对路径要求。cwd 参数可用,但仅用于通过 toDisplayPath 格式化显示路径,不用于绝对化存储路径。
|
||||
- 修复建议: 在发送前对每个发出的路径针对会话 cwd 进行解析:
|
||||
|
||||
~~~ts
|
||||
import { isAbsolute, resolve } from 'node:path'
|
||||
const abs = (p?: string) => p && cwd ? (isAbsolute(p) ? p : resolve(cwd, p)) : p
|
||||
// then: locations: filePath ? [{ path: abs(filePath), line: offset ?? 1 }] : []
|
||||
// and for diff content: path: abs(filePath)
|
||||
~~~
|
||||
|
||||
应用于 Read/Write/Edit/Glob 和 toolUpdateFromEditToolResponse。
|
||||
|
||||
### 5.6 [minor] 无 delete / move ToolKind 映射
|
||||
|
||||
- 位置: `src/services/acp/bridge.ts:191-411` (toolInfoFromToolUse)——kind coverage
|
||||
- 规范要求: ToolKind enum (schema.json:3616-3670): `read`、`edit`、`delete`、`move`、`search`、`execute`、`think`、`fetch`、`switch_mode`、`other`。Tools that remove or rename files SHOULD map to `delete` / `move` so clients can render appropriate UI (schema.json:3629-3638)。
|
||||
- 当前实现: 大多数工具映射正确（Read→read、Write/Edit→edit、Bash→execute、Grep/Glob→search、WebFetch/WebSearch→fetch、Agent/TodoWrite→think、ExitPlanMode→switch_mode、default→other）。然而,没有为任何 delete 或 move 工具（例如,假设的 rm/mv 工具或 MCP filesystem delete）的映射——这样的工具落入 `other`。这在规范内（'other' 是有效的）但丢失了语义提示。
|
||||
- 修复建议: 如果/当 delete/move 工具通过 ACP 连接时,添加显式 case,例如 `case 'Remove': case 'Delete': → kind:'delete'`；`case 'Move': case 'Rename': → kind:'move'`。低优先级,直到这样的工具出现。
|
||||
|
||||
### 5.7 [nit] ExitPlanMode optionId 与 session-mode ID 碰撞
|
||||
|
||||
- 位置: `src/services/acp/permissions.ts:185-209` (handleExitPlanMode options) 和 244-254 (selectedOption check)
|
||||
- 规范要求: PermissionOption.optionId is a free-form string (schema.json:1988-1990) with no enum constraint, so the custom optionIds `auto`、`acceptEdits`、`default`、`plan`、`bypassPermissions` are schema-valid。然而,与 session-mode ID 碰撞的 optionId 值是应用级歧义,PermissionOptionKind 是唯一标准化的 hint（四变体枚举）。对于实际上切换会话模式的选项（auto/acceptEdits/bypassPermissions）使用 `kind:'allow_always'` 过载了 allow_always 语义。
|
||||
- 当前实现: ExitPlanMode 发出 4-5 个自定义选项,其中 optionId 等于会话模式 id。kind 字段设置为 allow_always/allow_once/reject_once 作为粗略提示,但 optionId 空间（模式 id）是 Claude-Code 约定,未在协议中文档化。这是允许的可扩展性,但 kind 不忠实地描述 "此选项更改会话模式"。
|
||||
- 备注: 不是硬性违规,因为 optionId 是 free-form,ExitPlanMode 映射到有效的 ToolKind `switch_mode`。
|
||||
- 修复建议: 可按原样接受；考虑在这些选项上添加 `_meta` hint（例如 `_meta.claudeCode.changesMode = true`）,以便客户端可以不同地渲染它们,并确保 optionId 值在 agentCapabilities._meta 中文档化为 Claude-Code 特定的。
|
||||
|
||||
### 5.8 [nit] rawInput 浅克隆,易受嵌套突变影响
|
||||
|
||||
- 位置: `src/services/acp/bridge.ts:1283-1316` (rawInput construction in toAcpNotifications)
|
||||
- 规范要求: ToolCallUpdate.rawInput (schema.json:3583-3585) is described as "Update the raw input" with no explicit type constraint (free-form)。It is intended to carry the raw tool input parameters (Record<string, unknown>)。
|
||||
- 当前实现: `const rawInput = toolInput ? { ...toolInput } : {}` 是一个浅克隆；嵌套对象通过引用与实时 tool input 共享。如果在通知序列化之前对嵌套字段进行后续突变,则发出的 rawInput 可以反映执行后状态而不是发送的输入。Schema-valid 但语义脆弱。
|
||||
- 修复建议: 深克隆（`structuredClone(toolInput)`）或 JSON-round-trip 输入,然后再附加为 rawInput,以保证捕获的值与实际发送给工具的值匹配。

## 6. session/set_mode + session/set_model + session/set_config_option + modes/models/configOptions 形状（维度 6）
|
||||
|
||||
### 6.1 [major] setSessionMode 改变 mode 后未发 current_mode_update 通知
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:396-407` (setSessionMode)
|
||||
- 规范要求: session-modes.mdx 第 105-121 行: "The Agent can also change its own mode and let the Client know by sending the current_mode_update session notification。" schema.json:1142-1160 CurrentModeUpdate / SessionUpdate variant `current_mode_update` (schema.json:3060-3075)。当 Agent 改变 mode 后 MUST 发送 current_mode_update 通知,使只支持 modes API（不支持 configOptions）的 Client 能感知 mode 切换。
|
||||
- 当前实现: setSessionMode 调用 applySessionMode（更新内部 session.modes.currentModeId）然后 updateConfigOption('mode', ...) 只发送 config_option_update 通知（agent.ts:862-868）。从不发送 current_mode_update 通知。仅支持 modes 的 Client 将永远收不到 setSessionMode 之后的 mode 变更通知。
|
||||
- 修复建议: 在 setSessionMode 中,在 applySessionMode 之后追加发送 current_mode_update:
|
||||
|
||||
~~~diff
|
||||
async setSessionMode(params: SetSessionModeRequest): Promise<SetSessionModeResponse> {
|
||||
const session = this.sessions.get(params.sessionId)
|
||||
if (!session) throw new Error('Session not found')
|
||||
this.applySessionMode(params.sessionId, params.modeId)
|
||||
+ await this.conn.sessionUpdate({
|
||||
+ sessionId: params.sessionId,
|
||||
+ update: { sessionUpdate: 'current_mode_update', currentModeId: params.modeId },
|
||||
+ })
|
||||
await this.updateConfigOption(params.sessionId, 'mode', params.modeId)
|
||||
return {}
|
||||
}
|
||||
~~~
|
||||
|
||||
参照 setSessionConfigOption 中 `configId==='mode'` 分支（agent.ts:447-455）已有的 current_mode_update 发送逻辑保持一致。
|
||||
|
||||
### 6.2 [minor] NewSession/Load/Resume 响应携带非稳定 v1 models 字段
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:675-680` (createSession 返回值) 及 715-720 (getOrCreateSession 返回值)
|
||||
- 规范要求: schema.json:1916-1955 NewSessionResponse 仅定义 sessionId（必填）、configOptions（可选）、modes（可选）、`_meta`。LoadSessionResponse（schema.json:1668-1697）/ResumeSessionResponse 同样不含 models 字段。v1 稳定 schema 中不存在 SessionModelState/SessionModel/SetSessionModel,model 选择属于 draft/unstable 特性。
|
||||
- 当前实现: createSession 返回 `{ sessionId, models, modes, configOptions }`,getOrCreateSession 返回值同样包含 models。models 字段在 v1 稳定 schema 中未定义,严格 Client 会忽略它。该字段由 @agentclientprotocol/sdk@0.19.0 的 draft 类型（SessionModelState/ModelInfo）驱动。
|
||||
- 修复建议: 由于 model 选择为 draft 特性且不在 v1 合规范围,建议: (1) 若仅面向 v1 Client,从 NewSessionResponse/LoadSessionResponse/ResumeSessionResponse 返回值中移除 models 字段,仅保留 sessionId/modes/configOptions；或 (2) 若需保留向后兼容,在响应中保留 models 但明确文档标注为非稳定扩展。最小合规改动:
|
||||
|
||||
~~~diff
|
||||
-return { sessionId, models, modes, configOptions }
|
||||
+return { sessionId, modes, configOptions }
|
||||
~~~
|
||||
|
||||
### 6.3 [minor] setSessionConfigOption 未校验 value 是否在 options 列表内
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:427-469` (setSessionConfigOption)
|
||||
- 规范要求: session-config-options.mdx 第 189-192 行: "value: The new value to set. Must be one of the values listed in the option's options array。" schema.json:3110-3147 SetSessionConfigOptionRequest 的 value 为 SessionConfigValueId,Agent 应在 option.options 内校验该 value 合法性,非法值应返回错误而非静默接受。
|
||||
- 当前实现: setSessionConfigOption 通过 id 查找 option（agent.ts:440-443）,但从不校验 params.value 是否存在于 option.options 中。任何字符串（即使不在 options 列表）都会被接受并写入 currentValue,违反 "Must be one of the values listed" 要求。
|
||||
- 修复建议: 在 option 查找后追加 options 校验:
|
||||
|
||||
~~~ts
|
||||
const option = session.configOptions.find(o => o.id === params.configId)
|
||||
if (!option) throw new Error(`Unknown config option: ${params.configId}`)
|
||||
const validValues = flattenOptions(option.options).map(o => o.value)
|
||||
if (!validValues.includes(params.value)) {
|
||||
throw new Error(
|
||||
`Invalid value '${params.value}' for config option ${params.configId}; must be one of: ${validValues.join(', ')}`,
|
||||
)
|
||||
}
|
||||
~~~
|
||||
|
||||
注意 options 可能为 grouped（SessionConfigSelectGroup）或 flat（SessionConfigSelectOption）,需 flatten 处理。
|
||||
|
||||
### 6.4 [nit] value 类型守卫冗余
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:434-438` (setSessionConfigOption value 类型守卫)
|
||||
- 规范要求: schema.json:3134-3141 SetSessionConfigOptionRequest.value 引用 SessionConfigValueId（schema.json:2779-2782 type:'string'）。value 始终为字符串。
|
||||
- 当前实现: 实现包含 `if (typeof params.value !== 'string') throw`,但因 schema 已将 value 固定为 string,此守卫永远为真,属冗余代码。同时该守卫位置在 option 查找之前,错误信息不够精准。
|
||||
- 修复建议: 由于 SessionConfigValueId 严格为 string,可移除该类型守卫（由 SDK/schema 层保证）；或保留但移至 option.options 校验统一处理,避免分散校验逻辑。

## 7. ContentBlock 处理: text/image/audio/resource/resourceLink/thought（维度 7）
|
||||
|
||||
### 7.1 [major] promptCapabilities.image 声明但 promptConversion 完全不解析图片
|
||||
|
||||
- 位置: `src/services/acp/promptConversion.ts:3` (promptToQueryInput) 与 `src/services/acp/agent.ts:155-158` (initialize)
|
||||
- 规范要求: schema.json PromptCapabilities.image (line 2126): "Agent supports [ContentBlock::Image]"；content.mdx line 42-55: Image blocks in prompts "Requires the image prompt capability when included in prompts。" 声明了能力就必须能处理对应的 prompt 输入 ContentBlock。
|
||||
- 当前实现: agent.ts initialize() 声明 `promptCapabilities.image = true`,但 promptToQueryInput() 完全没有 'image' 分支——image block 既不被 base64 解码转成 Claude SDK 的 image content,也不产生任何文本占位,被静默丢弃。客户端按 `image:true` 发送图片 prompt 后内容丢失,无报错。
|
||||
- 修复建议: 在 promptConversion.ts 增加 image 分支: 将 ACP `{type:'image', data, mimeType}` 转换为 Claude SDK 的 image content block 传给 query（若 query input 仅接受 string,则需扩展 promptToQueryInput 返回 ContentBlock[] 而非 string）。或者若当前 query 层暂不支持多模态输入,应将 `image:false`,使声明与实现一致,并由客户端回退到文本/链接形式。推荐先降级 `image:false`,待多模态 query input 支持后再开启。此问题与维度 1 §1.1、维度 3 §3.1 同根因。
|
||||
|
||||
### 7.2 [major] embeddedContext=true 但 BlobResource 被静默丢弃
|
||||
|
||||
- 位置: `src/services/acp/promptConversion.ts:19-24` (resource 分支) 与 `src/services/acp/agent.ts:157`
|
||||
- 规范要求: schema.json PromptCapabilities.embeddedContext (line 2121): 启用时客户端可发送 ContentBlock::Resource；content.mdx line 124-155: EmbeddedResource 支持 TextResource（`{uri,text,mimeType?}`）与 BlobResource（`{uri,blob,mimeType?}`）两种形式。
|
||||
- 当前实现: 声明 `embeddedContext=true`,但 promptToQueryInput 的 'resource' 分支仅提取 `resource.text`。当客户端发送 BlobResource（如 PDF/二进制文件,字段为 `resource.blob + resource.mimeType + resource.uri`）时,text 为 undefined,内容被完全丢弃,模型只收到空字符串。也未传递 uri/mimeType 上下文。
|
||||
- 修复建议: 扩展 resource 分支:
|
||||
|
||||
~~~ts
|
||||
} else if (b.type === 'resource') {
|
||||
const r = b.resource as Record<string, unknown> | undefined
|
||||
if (r && typeof r.text === 'string') {
|
||||
parts.push(r.text)
|
||||
} else if (r && typeof r.blob === 'string') {
|
||||
const mt = typeof r.mimeType === 'string' ? r.mimeType : 'application/octet-stream'
|
||||
parts.push(`Embedded resource: ${r.uri ?? '(unknown uri)'} (${mt}, base64 blob)`)
|
||||
}
|
||||
}
|
||||
~~~
|
||||
|
||||
（理想做法是将 blob 解码并作为 Claude SDK 二进制 content 传入 query；若 query input 不支持则至少以可读占位形式保留上下文,不能静默丢弃。）
|
||||
|
||||
### 7.3 [minor] toAcpContentBlock 未处理 resource/resource_link 导致降级为 JSON 文本
|
||||
|
||||
- 位置: `src/services/acp/bridge.ts:572` (toAcpContentBlock)
|
||||
- 规范要求: schema.json ContentBlock.oneOf 包含 ResourceLink (line 1023) 与 EmbeddedResource (line 1039)；content.mdx line 163: ResourceLink 在 prompt 中 ALL agents MUST support；content.mdx line 11: ContentBlock 也用于 session/update 输出与 tool 结果。
|
||||
- 当前实现: toAcpContentBlock（输出渲染）只显式处理 text/image 及若干 Claude 私有 content 类型；'resource' 和 'resource_link' 类型的 SDK content 落入 default 分支（line 644-648）被序列化为 `{type:'text', text: JSON.stringify(content)}`,产生非规范输出,客户端无法识别为可点击资源。
|
||||
- 修复建议: 在 toAcpContentBlock switch 中增加 case:
|
||||
|
||||
~~~ts
|
||||
case 'resource_link':
|
||||
return { type: 'resource_link', uri: content.uri as string, name: (content.name as string) ?? (content.uri as string), mimeType: content.mimeType as string | undefined }
|
||||
case 'resource': {
|
||||
const r = content.resource as Record<string, unknown> | undefined
|
||||
return { type: 'resource', resource: { uri: r?.uri, mimeType: r?.mimeType, text: r?.text, blob: r?.blob } }
|
||||
}
|
||||
~~~
|
||||
|
||||
注意 ImageContent 与 ResourceLink 字段差异: ImageContent 必填 data+mimeType（base64）,uri 为可选；ResourceLink 必填 name+uri,没有 data 字段。
|
||||
|
||||
### 7.4 [minor] toAcpContentBlock image 分支 url 处理字段命名澄清
|
||||
|
||||
- 位置: `src/services/acp/bridge.ts:596-600` (toAcpContentBlock image 分支 url/非 base64 处理)
|
||||
- 规范要求: schema.json ImageContent (line 1384-1414): 必填 data（base64）+ mimeType,uri 为可选 string|null。ACP v1 ContentBlock 不支持纯 URL 图片——没有 url 字段,只有可选 uri 引用且仍需 data。
|
||||
- 当前实现: 当 Claude SDK image content 的 `source.type === 'url'` 时,降级输出文本占位 `[image: <url>]`。这本身符合 ACP（因 ACP 要求 base64 data,URL 图片无法原样转发）。但实现中读取的字段名是 source.url（Claude SDK 私有形态）,与 ACP 无关；同时未考虑 `source.type` 可能既非 base64 也非 url 的情形已用 '[image: file reference]' 覆盖。逻辑可接受,无违规,仅记录字段命名澄清。
|
||||
- 修复建议: 无需协议层修复。如要增强: 可将 url 图片自行 fetch+base64 编码后转为合规 ImageContent,但需注意安全与性能；当前文本占位降级是合规的最低实现。保持现状即可,此条仅作字段映射文档。
|
||||
|
||||
### 7.5 [nit] audio 能力声明与实现一致（合规,仅记录）
|
||||
|
||||
- 位置: `src/services/acp/agent.ts:155-158` (initialize promptCapabilities)
|
||||
- 规范要求: schema.json PromptCapabilities.audio (line 2116, default false)。content.mdx line 74-87: audio block 需 audio capability。
|
||||
- 当前实现: promptCapabilities 未声明 audio（默认 false）,且 promptConversion.ts 与 bridge.ts toAcpContentBlock 均无 audio 处理。声明与实现一致（均不支持）,符合规范。但输出侧 toAcpContentBlock 也没有 audio 分支——若 Claude 未来输出音频 content 会落入 JSON.stringify。
|
||||
- 修复建议: 无需修改；当前状态合规。如未来支持音频输入,需同时: (1) agent.ts 声明 `audio:true`；(2) promptConversion.ts 增加 audio→Claude SDK audio block 转换；(3) bridge.ts toAcpContentBlock 增加 `case 'audio'` 输出 `{type:'audio', data, mimeType}`。三者必须同步,避免再次出现 image 那种声明/实现脱节。
|
||||
|
||||
### 7.6 [nit] thought / tool_result 映射合规（无需修改）
|
||||
|
||||
- 位置: `src/services/acp/promptConversion.ts:8-27` 与 `src/services/acp/bridge.ts:1210-1247` (thought / tool_result)
|
||||
- 规范要求: schema.json ContentBlock.oneOf (line 966-1053) 仅含 text/image/audio/resource_link/resource 五种——不存在 ThoughtContent；thought 通过 SessionUpdate discriminator `agent_thought_chunk` (schema.json line 2989) 表达,而非 ContentBlock type 或 `role:'thought'`。tool 结果应通过 tool_call_update (schema.json line 3012+) 传递。
|
||||
- 当前实现: 实现正确,无需修改。
|
||||

## 8. transports / JSON-RPC envelope / acp-link 代理合规（维度 8）
|
||||
|
||||
### 8.1 [critical] acp-link WS 使用自有 `{type,payload}` 封装而非 JSON-RPC 2.0
|
||||
|
||||
- 位置: `packages/acp-link/src/server.ts:147-156` (send), 800-878 (decodeClientMessage), `packages/acp-link/src/ws-message.ts:52-63`
|
||||
- 规范要求: transports.mdx L52: "Custom transports MUST ensure they preserve the JSON-RPC message format and lifecycle requirements defined by ACP." overview.mdx L206: "The JSON-RPC envelope fields (jsonrpc, id, method, params, result, and error) follow the JSON-RPC 2.0 specification." transports.mdx L6: "ACP uses JSON-RPC to encode messages."
|
||||
- 当前实现: acp-link 在 client↔proxy WS 之间使用自有的包装格式 `{ type: string, payload?: unknown }`,而不是 JSON-RPC。ws-message.ts:decodeJsonWsMessage 强制要求每个传入消息包含 'type' 字符串；server.ts:decodeClientMessage 随后切换此 type。客户端发送的任何标准 JSON-RPC 消息（`{ jsonrpc:'2.0', id, method, params }`）均会被拒绝,错误提示为 "Invalid WebSocket message payload" (ws-message.ts:60)。stdout↔stdio 部分使用了正确的 SDK ndJsonStream,但面向客户端的 WS 传输（即实际上暴露给客户端的自定义传输）并非 JSON-RPC。
|
||||
- 修复建议: 使面向客户端的 WS 传输成为透明的 JSON-RPC 转发器。通过 JSON-RPC method 名而非专有的 `type` 进行路由,并完整透传消息。最小改造方案:
|
||||
|
||||
~~~ts
|
||||
// onMessage: 解析一次 JSON-RPC,然后路由到处理程序
|
||||
const msg = JSON.parse(text) as JsonRpcMessage
|
||||
if ('method' in msg) {
|
||||
// 请求或通知 — 根据 msg.method 进行分发
|
||||
const result = await dispatchMethod(msg.method, msg.params)
|
||||
if ('id' in msg) send(ws, { jsonrpc:'2.0', id: msg.id, result })
|
||||
} else {
|
||||
// 响应 — 关联到待处理的出站请求 id
|
||||
}
|
||||
~~~
|
||||
|
||||
### 8.2 [critical] 代理响应丢弃 JSON-RPC id,无法关联请求
|
||||
|
||||
- 位置: `packages/acp-link/src/server.ts:147-156` (send), 412-416 (session_created), 624 (prompt_complete), 473-483 (session_list)
|
||||
- 规范要求: JSON-RPC 2.0 spec §6: Request 必须包含 `id`；Response 必须包含相同的 `id`、`result` 或 `error`,并带有 `jsonrpc: "2.0"`。overview.mdx L10-13: "请求-响应对期望得到结果或错误"。
|
||||
- 当前实现: 代理针对客户端请求的响应（例如 `session_created`、`prompt_complete`、`session_list`、`session_loaded`、`model_changed`）使用带有自选 `type` 字符串的 `send(ws, type, payload)`,且从不携带 JSON-RPC `id`。客户端无法将响应与原始请求相关联,因为代理丢弃了请求 id。整个链路中没有任何 `id` 保留。
|
||||
- 修复建议: 在 ClientState 上保留一个挂起的 id 映射,并在 JSON-RPC 响应中回显请求的 `id`:
|
||||
|
||||
~~~ts
|
||||
send(ws, { jsonrpc:'2.0', id: pendingId, result })
|
||||
~~~
|
||||
|
||||
### 8.3 [major] 错误响应使用专有 ProxyError 而非 JSON-RPC 错误对象
|
||||
|
||||
- 位置: `packages/acp-link/src/server.ts:358-360, 379, 392, 419-421, 450-453, 486-489, 537-540, 626, 696-699, 1166`；`packages/acp-link/src/types.ts:78-82` (ProxyError)
|
||||
- 规范要求: overview.mdx L198-201: "所有方法均遵循标准 JSON-RPC 2.0 错误处理……错误包含一个带有 `code` 和 `message` 的 `error` 对象。" JSON-RPC 2.0 预留代码: -32700 解析错误、-32600 无效请求、-32601 方法未找到、-32602 无效参数、-32603 内部错误。
|
||||
- 当前实现: 所有错误均以专有的 ProxyError `{ type: 'error', message: string, code?: string }` 发出,且没有 JSON-RPC 错误对象,也没有数值类型的 JSON-RPC 代码。例如 server.ts:358 发送 `{ message: 'Failed to connect: ...' }`。`code` 字段是一个自由格式字符串,从未使用过 -326xx 代码。不相关的客户端无法区分解析错误、方法未找到错误和内部错误。
|
||||
- 修复建议: 发出标准的 JSON-RPC 错误响应,关联到请求 id:
|
||||
|
||||
~~~ts
|
||||
send(ws, { jsonrpc:'2.0', id: reqId, error: { code: -32601, message: 'Not connected to agent' } })
|
||||
~~~
|
||||
|
||||
将已知故障映射到代码: -32700 (decodeJsonWsMessage 解析失败)、-32602 (payloadRecord/optionalStringField 验证)、-32601 (代理不支持该功能或 SDK 调用抛出"不支持")、-32603 (内部异常)。
|
||||
|
||||
### 8.4 [major] decodeClientMessage 白名单狭窄,多个 v1 方法无传输路径
|
||||
|
||||
- 位置: `packages/acp-link/src/server.ts:800-878` (decodeClientMessage switch), 871 `default: throw new Error('Unknown message type')`
|
||||
- 规范要求: schema/meta.json 列出了 12 个 agent 方法（authenticate、initialize、logout、session/close、session/set_mode、session/set_config_option 等）和 9 个 client 方法（terminal/*、fs/*）。overview.mdx L52 (自定义传输): 必须保留 JSON-RPC 格式和生命周期。未知方法必须产生 JSON-RPC -32601 method-not-found 错误,而不是断开客户端连接。
|
||||
- 当前实现: decodeClientMessage 在遇到未知 `type` 时抛出异常,这会导致 onMessage 捕获程序发出通用的 `{ type:'error', message:'Unknown message type: ...' }` (server.ts:1166),但不会发出 -32601 响应。更糟糕的是,代理仅识别固定的方法白名单（connect、disconnect、new_session、prompt、permission_response、cancel、set_session_model、list/load/resume_session、ping）。客户端发起的 `authenticate`、`logout`、`session/close`、`session/set_mode`、`session/set_config_option`、`session/list`（与 list_sessions 不同——注意 meta.json 中的方法名是 `session/list`）以及所有 terminal/* 方法在传输中均无路径。这些方法在协议层被悄悄丢弃。
|
||||
- 修复建议: 用通用的 JSON-RPC 方法路由器替换专有的 type 切换。对于任何识别出但代理未实现的方法,返回 -32601。至少要透传 `session/set_mode` 和 `session/close`（这些是 v1 的基准/常用方法）。
|
||||
|
||||
### 8.5 [major] 未处理 JSON-RPC 标准 `$/cancel_request`
|
||||
|
||||
- 位置: `packages/acp-link/src/`（全仓库）；在 acp-link 中 grep `$/cancel_request` 无结果
|
||||
- 规范要求: JSON-RPC 2.0 spec §6.1: `$/cancel_request` 是用于取消正在进行的请求/通知的标准、传输级取消原语。这与 ACP 特有的 `session/cancel` 通知不同。ACP 透传传输必须将其转发到 stdio 代理进程或进行本地处理。
|
||||
- 当前实现: 未实现。仅处理专有的 `cancel` 类型 (server.ts:646),它映射到 ACP `session/cancel`。JSON-RPC 级别的 `$/cancel_request` 既未转发给 agent,也未映射到挂起的提示取消。如果客户端发送 `{ "jsonrpc":"2.0", "method":"$/cancel_request", "params": { id: ... } }`,当前解码器会将其拒绝为 "Invalid WebSocket message payload",因为它缺少专有的 `type` 字段。
|
||||
- 修复建议: 在 JSON-RPC 路由层增加对 `$/cancel_request` 的处理程序: 取消关联的出站提示请求,并转发到底层 SDK 连接的取消路径（或在 agent 上调用 `session/cancel`）。
|
||||
|
||||
### 8.6 [major] 代理重构 agentCapabilities 白名单,丢弃扩展能力
|
||||
|
||||
- 位置: `packages/acp-link/src/server.ts:321-330`
|
||||
- 规范要求: ACP 通过 agentCapabilities 按字段协商能力；未来/扩展能力（例如 auth、terminal）必须完整透传给客户端,以便其知道自己可以使用哪些方法。
|
||||
- 当前实现: server.ts:321-330 通过列出白名单字段（_meta、loadSession、mcpCapabilities、promptCapabilities、sessionCapabilities）来重构 `state.agentCapabilities`。任何 SDK 的 AgentCapabilities 携带但此处硬编码接口 (server.ts:65-79) 中未列出的字段（例如 `auth`、`terminal`、未来的能力）都会被静默丢弃,不会向客户端通告。
|
||||
- 修复建议: 直接透传原始的 `initResult.agentCapabilities` 对象,而不是重构它:
|
||||
|
||||
~~~diff
|
||||
-state.agentCapabilities = { /* whitelisted fields */ }
|
||||
+state.agentCapabilities = agentCaps ?? null
|
||||
~~~
|
||||
|
||||
仅在需要本地 TS 类型时进行收窄——但在传输中发送未收窄的值。
|
||||
|
||||
### 8.7 [major] 硬编码 clientInfo/capabilities,丢弃客户端真实信息
|
||||
|
||||
- 位置: `packages/acp-link/src/server.ts:313-319`
|
||||
- 规范要求: overview.mdx L20-24: 客户端 → agent: `initialize` 以协商连接。InitializeParams 携带客户端真实的 `clientInfo`（`{name, version}`）,以便 agent 进行日志记录/遥测。clientCapabilities 同样必须反映真实的客户端能力。
|
||||
- 当前实现: 代理硬编码 `clientInfo: { name: 'zed', version: '1.0.0' }` 和 `clientCapabilities: { fs: { readTextFile: true, writeTextFile: true } }`,忽略客户端实际发送的任何 clientInfo/capabilities。非 Zed 客户端（Web UI、RCS 中继、自定义客户端）被错误地呈现给 agent 为 'zed 1.0.0',并可能通告了它并不支持的 fs 能力。
|
||||
- 修复建议: 接受来自客户端 initialize 消息的 clientInfo 和 clientCapabilities 并进行转发。仅使用 'zed'/{fs:true} 作为代理内部未提供任何信息时的回退。
|
||||
|
||||
### 8.8 [major] types.ts ClientCapabilities/ServerCapabilities 形状陈旧
|
||||
|
||||
- 位置: `packages/acp-link/src/types.ts:96-113` (ClientCapabilities, ServerCapabilities)
|
||||
- 规范要求: schema.json InitializeParams.clientCapabilities 和 InitializeResult.agentCapabilities 使用特定形状（例如带有嵌套 `fs.readTextFile/writeTextFile` 的 clientCapabilities；agentCapabilities = loadSession、mcpCapabilities、promptCapabilities、sessionCapabilities）。overview.mdx L206: 协议对象键使用 camelCase。
|
||||
- 当前实现: types.ts:96-113 定义了过时的形状——`ClientCapabilities { streaming?, toolApproval? }` 和 `ServerCapabilities { streaming?, tools? }`——这与实际的 ACP v1 schema 不匹配。这些类型虽然已声明但从未通过 JSON-RPC 路径实际使用；它们具有误导性,并暗示代理正在协商 ACP 中不存在的 streaming/tools 能力。
|
||||
- 修复建议: 完全移除过时的 `ClientCapabilities`/`ServerCapabilities` 类型（它们在任何实时代码路径中均未使用——server.ts 使用其内联的 `AgentCapabilities`）,或用 SDK 定义的结构替换它们。
|
||||
|
||||
### 8.9 [minor] agentInfo 类型收窄过紧,丢失扩展字段
|
||||
|
||||
- 位置: `packages/acp-link/src/types.ts:63-71` (ProxyStatus.agentInfo), `packages/acp-link/src/server.ts:346`
|
||||
- 规范要求: ACP agentInfo（InitializeResult.agentInfo）至少为 `{ name, version }`,但根据 extensibility.mdx 可以携带额外的 _meta/扩展字段；自定义传输应保留它。
|
||||
- 当前实现: ProxyStatus 类型将 `agentInfo` 收窄为 `{ name?: string; version?: string }` (types.ts:66-69)。实际发送的对象 (server.ts:346) 是原始的 `initResult.agentInfo`,所以运行时没问题,但声明的类型会丢弃 TS 认为客户端收到的任何附加字段,且阅读此类型的客户端无法依赖扩展的 agentInfo。types.ts:87-108 中类似地过时的 InitializeParams/InitializeResult 与 SDK 的实际形状不匹配。
|
||||
- 修复建议: 加宽类型:
|
||||
|
||||
~~~ts
|
||||
agentInfo?: { name: string; version: string; [k: string]: unknown }
|
||||
~~~
|
||||
|
||||
或者通过 SDK 重新导出真实的 InitializeResult 类型。
|
||||
|
||||
### 8.10 [minor] session/update 通知方向正确（合规,记录）
|
||||
|
||||
- 位置: `packages/acp-link/src/server.ts:190-192` (createClient.sessionUpdate)
|
||||
- 规范要求: overview.mdx L180-189: `session/update` 是一个 agent→client 通知（无响应）。
|
||||
- 当前实现: 正确: sessionUpdate 流向 agent→client（通过 SDK ClientSideConnection 回调,然后 `send(ws, 'session_update', params)`）。代理在 client→agent 方向上不接受 `session_update`（decodeClientMessage 没有该情况）。此处未发现问题——为完整性而列出。
|
||||
- 修复建议: 无需操作；行为正确。仅将其记录为已验证项。
|
||||
|
||||
### 8.11 [minor] 应用层 ping/pong 与传输级 WS 心跳冗余
|
||||
|
||||
- 位置: `packages/acp-link/src/server.ts:915-917` (ping → pong)
|
||||
- 规范要求: WS-level ping/pong 在 RFC 6455 §5.5.2 中是传输级控制帧（二进制操作码 0x9/0xA）,而不是应用层消息。将它们与应用层消息混合是非标准的。ACP 本身没有应用层 ping 方法。
|
||||
- 当前实现: 代理实现了应用层的 `{ type: 'ping' }` / `{ type: 'pong' }` (server.ts:915-917),与传输级的 WS 心跳 (server.ts:1199-1216 通过 `ws.raw.ping()`) 并存。这是冗余的,且容易混淆——如果客户端将应用层 ping 发送为 JSON-RPC `{ method: 'ping' }`,它将无法与传输层帧区分,并会被拒绝。
|
||||
- 修复建议: 移除应用层的 ping/pong 情况；仅依赖传输级的 WS ping/pong 心跳 (server.ts:1199)。或者,如果需要,文档说明自定义 ping 并通过相同的 `{ type, payload }` 约定路由它。
|
||||
|
||||
### 8.12 [minor] RCS 中继路径同样施加 `{type,payload}` 封装
|
||||
|
||||
- 位置: `packages/acp-link/src/rcs-upstream.ts:117-149` (connect: REST + identify)
|
||||
- 规范要求: transports.mdx L52: 自定义传输必须保留 JSON-RPC 消息格式。ACP 规范未定义 RCS "环境/桥接" REST 注册或 WS `identify`/`identified`/`registered`/`keep_alive` 消息类型——这些是 RCS 特定的（超出 ACP v1 范围）。一旦注册,中继必须转发未更改的 JSON-RPC。
|
||||
- 当前实现: 两步流程（REST POST /v1/environments/bridge,然后 WS `identify`→`identified` 握手）是 RCS 专有的,对于 RCS 传输是可以接受的。但是,rcs-upstream.ts:151-221 中的中继消息处理程序通过相同的 `decodeJsonWsMessage`（要求 `{ type }` 形状）解码所有传入的服务器消息,并仅将非控制类型转发给 messageHandler (L213-219)。这意味着 RCS 和 agent 之间的中继也施加了 `{ type, payload }` 而非 JSON-RPC,这与主 WS 代理有相同的封装问题。
|
||||
- 修复建议: 对于从 RCS 到本地 agent 的中继路径,解码为 JSON-RPC 并路由方法名。控制消息（identify/identified/registered/keep_alive）属于 RCS 特有的带外,应通过单独的传输层接口处理,而不是与 ACP 有效负载复用。
|
||||
|
||||
### 8.13 [minor] 协议版本未在 status 消息中转发给客户端
|
||||
|
||||
- 位置: `packages/acp-link/src/server.ts:314` (acp.PROTOCOL_VERSION), 333-342 (logs protocolVersion)
|
||||
- 规范要求: ACP 稳定 protocolVersion 在 schema/meta.json 中为 `1`（整数）。InitializeResponse.protocolVersion 必须透传,以便客户端和 agent 就协商的版本达成一致。
|
||||
- 当前实现: 代理使用 SDK 常量 `acp.PROTOCOL_VERSION` 发送 initialize,并记录返回的 `initResult.protocolVersion` (server.ts:335),但从未在 `status`/`session_created` 消息中将 `protocolVersion` 转发给客户端客户端（send() 调用省略了它）。下游 WS 客户端无法观察协商的协议版本。未发现版本损坏（SDK 管理往返）,但客户端缺乏可见性。
|
||||
- 修复建议: 在连接后发送的 `status` 消息中包含 `protocolVersion: initResult.protocolVersion` (server.ts:344-348)。
|
||||
|
||||
### 8.14 [nit] JsonRpc 类型未使用（死代码）
|
||||
|
||||
- 位置: `packages/acp-link/src/types.ts:34-46` (isRequest/isResponse/isNotification)
|
||||
- 规范要求: JSON-RPC 2.0 spec §4.1/§4.2: Request = 带有 method+id 的对象；Notification = 带有 method 但无 id 的对象；Response = 带有 id 且无 method 的对象,以及 result 或 error。
|
||||
- 当前实现: 辅助函数看起来正确,但这些 JsonRpc 类型在 acp-link 运行时中的任何地方都未使用（代理绕过了它们而使用 `{type,payload}`）。死代码表明存在意图与实现之间的脱节。
|
||||
- 修复建议: 要么将 JSON-RPC 路由基于这些类型（首选——修复 §8.1 finding）,要么移除死类型以避免误导未来的维护者。

## 附录 A: SDK 方法命名对照
|
||||
|
||||
| SDK 方法 | 当前命名 | stable? | 修复动作 |
|
||||
|---|---|---|---|
|
||||
| initialize | initialize | stable | 保留（但需修 authMethods 缺失） |
|
||||
| authenticate | authenticate | stable | 保留（建议显式返回 authMethods:[]） |
|
||||
| logout | 未实现 | stable | 保留不实现（也未宣告 auth.logout 能力） |
|
||||
| newSession | newSession | stable | 保留 |
|
||||
| loadSession | loadSession | stable | 保留（需补 cwd 校验） |
|
||||
| unstable_resumeSession | unstable_resumeSession | stable (resumed) | 建议在 SDK 升级后改名为 `resumeSession`,同时去除重放历史 |
|
||||
| unstable_forkSession | unstable_forkSession | UNSTABLE | 保留 unstable 命名；但应从 sessionCapabilities.fork 迁移到 _meta.claudeCode.forkSession |
|
||||
| listSessions | listSessions | stable | 保留（需实现 cursor 分页） |
|
||||
| unstable_closeSession | unstable_closeSession | UNSTABLE | 保留 |
|
||||
| prompt | prompt | stable | 保留（需修 usage 字段、refusal 映射） |
|
||||
| cancel | cancel (notification) | stable | 保留 |
|
||||
| setSessionMode | setSessionMode | stable | 保留（需补 current_mode_update 通知） |
|
||||
| setSessionConfigOption | setSessionConfigOption | stable | 保留（需补 value 校验） |
|
||||
| unstable_setSessionModel | unstable_setSessionModel | UNSTABLE | 保留 |
|
||||
| session/update | sessionUpdate (notification) | stable | 保留（usage_update 为 UNSTABLE 但为 interop 保留,见 §4.1） |
|
||||
|
||||
## 附录 A.2: UNSTABLE RFD 实现记录（2026-06-19）
|
||||
|
||||
下列 UNSTABLE RFD 不属于严格 v1 合规范围,但为提升 interop 与客户端 UX 已主动实现。所有字段均已存在于 SDK 0.19.0 bundled schema 的 unstable 区段,主要 ACP 客户端（Zed / Cursor / RCS Web UI）均实现。
|
||||
|
||||
### A.2.1 session/delete（rfds/session-delete.mdx）✅ 已实现
|
||||
|
||||
- **能力广告**: `sessionCapabilities.delete: {}`（通过类型增强写入,因 SDK 0.19.0 的 SessionCapabilities 类型早于该 RFD）。
|
||||
- **方法路由**: SDK 0.19.0 的方法分发器 `default` 分支调用 `agent.extMethod(method, params)`,因此 `session/delete` 通过 extMethod 钩子路由到 `unstable_deleteSession`。
|
||||
- **语义**: 硬删除（unlink `~/.claude/projects/<sanitized-path>/<sessionId>.jsonl`）。spec 允许 soft/hard delete,选 hard delete 简化实现。
|
||||
- **幂等性**: 删不存在的 session 也成功（ENOENT 视为成功）。
|
||||
- **未知方法**: extMethod 对未识别方法抛 `RequestError.methodNotFound(method)`（JSON-RPC -32601）。
|
||||
- **测试覆盖**: 6 个测试用例（能力广播 / extMethod 路由 / 幂等 / 内存清理 / 缺 sessionId 拒绝 / 未知方法拒绝）。
|
||||
|
||||
### A.2.2 message-id（rfds/message-id.mdx）✅ 已实现
|
||||
|
||||
- **覆盖范围**: `agent_message_chunk` / `user_message_chunk` / `agent_thought_chunk` 三个 chunk update 携带 `messageId`（UUID）。同消息的所有 chunks 共享 ID,不同消息 ID 不同。
|
||||
- **不覆盖**: `tool_call` / `tool_call_update` / `plan` 不携带 messageId（spec 仅规定 chunk 类型）。
|
||||
- **生成策略**:
|
||||
- **Assistant 消息**: 在 `forwardSessionUpdates` 中维护 `currentAgentMessageId: string | null`,在 `stream_event` 或 `assistant` SDK 消息（`parent_tool_use_id === null`）首次出现时 lazy 生成 UUID；assistant 消息处理完后 reset 为 null,下一条触发新 UUID。所有 chunks（包括 streaming text/thinking 和最终 assistant message 中的 text/image）共享同一个 ID。
|
||||
- **Subagent 消息**（`parent_tool_use_id !== null`）: 不追踪 messageId,因 spec 中嵌套 tool 消息不属于顶层 chunk 流。
|
||||
- **历史重放**（`replayHistoryMessages`）: 每条 replayed user/assistant 消息独立生成 UUID（JSONL 不保留原始 ACP messageId）。
|
||||
- **格式**: `crypto.randomUUID()`（不用 Anthropic 的 `message.id` —— 它是 `msg_xxx` 格式,不符合 spec 要求的 UUID）。
|
||||
- **PromptRequest.messageId → PromptResponse.userMessageId**: 仅当客户端传入 `params.messageId` 时回显（spec 用词为 MAY 自行生成 → 取保守做法,不自行生成）。
|
||||
- **测试覆盖**: 7 个测试用例（assistant chunk / 多消息不同 ID / streaming 共享 ID / tool_call 不带 ID / subagent 不带 ID / replay per-message UUID / replay 字符串内容带 ID）+ 2 个 prompt 回显测试（echo / omit）。
|
||||
|
||||
## 附录 B: 不修复项及理由
|
||||
|
||||
以下 finding 出于技术权衡或非合规范围,暂不修复:
|
||||
|
||||
| Finding | 理由 |
|
||||
|---|---|
|
||||
| §1.2 sessionCapabilities.fork 仅作"迁移到 _meta"建议,未标记 P0 阻断 | fork 为 UNSTABLE,严格 v1 合规范围外；当前 schema 未设 `additionalProperties:false`,不会导致硬失败。优先用 _meta.claudeCode.forkSession 重构,不阻断。 |
|
||||
| §2.5 listSessions 空字符串 title | SessionInfo.title schema 允许 null；空字符串技术有效。基于磁盘的候选者很少幸存于空摘要。属表面问题。 |
|
||||
| §2.6 NewSessionResponse 不含 cwd | 规范本身不要求返回 cwd；记录是为了纠正审计检查清单的错误前提。 |
|
||||
| §3.5 prompt _meta 透传（W3C traceparent） | extensibility.mdx 用词为 SHOULD,非 MUST。OpenTelemetry interop 非当前部署场景的必需功能。列为 P2。 |
|
||||
| §3.7 空 prompt 提前返回 end_turn | 行为可接受（虽语义不严谨）；若改为抛出 -32602 需协调 Client 错误处理。列为 P2。 |
|
||||
| §3.8 usage 缺 thoughtTokens | 仅在保留 unstable usage 字段时才有意义；若按 §3.2 整体移除 usage,此项自动消失。 |
|
||||
| §4.4 Bash _meta 键未命名空间化 | 非规范违规（_meta 允许任意附加键）；仅命名风格不一致。 |
|
||||
| §5.4 reject_always 未提供 | PermissionOptionKind 四变体为推荐而非 MUST；REPL 现有交互流不支持持久的拒绝记忆。列为 P2。 |
|
||||
| §5.7 ExitPlanMode optionId 与 session-mode 碰撞 | optionId 是 free-form 字符串,使用模式 id 作为值是合法扩展；ExitPlanMode 映射为 switch_mode,语义可辨。 |
|
||||
| §5.8 rawInput 浅克隆 | Schema-valid,仅在嵌套对象被后续突变时才有问题；Claude Code 工具 input 通常不可变。低风险。 |
|
||||
| §6.2 响应中携带 models 字段 | 为 SDK draft 类型驱动,严格 v1 Client 会忽略；若客户端使用 SDK 同版本,则 models 是有用的扩展字段。优先移除但非阻断。 |
|
||||
| §6.4 value 类型守卫冗余 | 不影响合规性,仅代码质量问题。 |
|
||||
| §7.4 image url 占位字段命名 | 实现合规,仅为字段映射文档。 |
|
||||
| §7.5 audio 不支持 | 声明与实现均不支持,完全合规。 |
|
||||
| §7.6 thought / tool_result 映射 | 实现正确,无需修改。 |
|
||||
| §8.10 session/update 通知方向 | 行为正确,为完整性记录。 |
|
||||
| §8.11 应用层 ping/pong | 冗余但无害；仅在客户端用 JSON-RPC `ping` 时混淆。低优先级。 |
|
||||
| §8.14 JsonRpc 死类型 | 不影响运行时；仅在 §8.1 修复时一并清理。 |
|
||||
|
||||
## 附录 C: 修复路径建议
|
||||
|
||||
### P0 阻断修复（合规性硬阻塞）
|
||||
|
||||
1. **acp-link JSON-RPC 传输改造**（§8.1、§8.2、§8.3、§8.4、§8.5）——成本高,但属协议层根本缺陷。需要将 WS 解码/编码从 `{type,payload}` 改为 JSON-RPC 2.0,保留请求 id,使用标准错误代码,实现通用方法路由。建议分两阶段: 第一阶段透传所有未识别方法（修复 §8.4）+ 标准 id 关联（§8.2）+ 标准错误（§8.3）；第二阶段迁移到完全 JSON-RPC（§8.1）+ 实现 `$/cancel_request`（§8.5）。
|
||||
|
||||
2. **image 能力降级为 false**（§1.1、§3.1、§7.1）——低成本,只需一行改动,立即消除协议谎言。多模态 query input 完成后再恢复 `image:true`。
|
||||
|
||||
3. **session/resume 去除重放**（§2.1）——中成本,需要将 resume 与 load 路径分离,引入 `replay` 标志。
|
||||
|
||||
4. **~~删除 usage_update 通知~~（§4.1）** —— ⚠️ **已撤销**: 删除后客户端显示 0/0,严重破坏 interop。现保留 `usage_update` 发送(见 §4.1 决策回滚说明)。
|
||||
|
||||
### P1 重要修复（非阻断但影响协议契约）
|
||||
|
||||
1. **PromptResponse.usage 字段移至 _meta**（§3.2）
|
||||
2. **refusal stop_reason 映射**（§3.3）
|
||||
3. **terminal 能力标准生命周期**（§5.1、§5.2）——成本高,涉及 terminal/create/release RPC 调用
|
||||
4. **cancelled 权限结果传播**（§5.3）
|
||||
5. **setSessionMode 发送 current_mode_update**（§6.1）
|
||||
6. **session/load 跨项目 cwd 校验**（§2.2）
|
||||
7. **unstable_forkSession 实现真正分叉**（§2.3）
|
||||
8. **BlobResource 处理**（§7.2）
|
||||
9. **agentCapabilities/clientInfo 透传**（§8.6、§8.7）
|
||||
10. **ClientCapabilities/ServerCapabilities 类型陈旧**（§8.8）

# ACP Refactor Plan: Splitting 3 Large Files into Modular Sub-files
|
||||
|
||||
This document is the authoritative migration plan for splitting three oversized ACP (Agent Client Protocol) source files into modular sub-files. Each file exceeds the 500-line-per-module budget; the refactor preserves every public export path so that **no test file and no external consumer requires modification**.
|
||||
|
||||
**Hard constraints (all three refactors):**
|
||||
|
||||
1. All current public API export paths MUST remain working (`from '../server.js'`, `from '../bridge.js'`, `from '../agent.js'`).
|
||||
2. Every new file MUST be under 500 lines.
|
||||
3. Test files MUST NOT be modified — including `permissions.test.ts` which does `require('../bridge.ts')` and snapshots the **entire** export surface (so the bridge barrel MUST export exactly the public API, no more, no less).
|
||||
4. Only the 3 target files and their NEW sub-modules may be modified.
|
||||
5. `bun run precheck` MUST pass after every step (typecheck + lint fix + test).
|
||||
|
||||
---
|
||||
|
||||
## Target Files (current state)
|
||||
|
||||
| File | Lines | Public API surface |
|
||||
|------|------:|--------------------|
|
||||
| `packages/acp-link/src/server.ts` | 1800 | 8 must-preserve symbols |
|
||||
| `src/services/acp/bridge.ts` | 1516 | 8 must-preserve symbols |
|
||||
| `src/services/acp/agent.ts` | 1297 | 1 must-preserve symbol (`AcpAgent`) |
|
||||
| **Total** | **4613** | |
|
||||
|
||||
---
|
||||
|
||||
## Migration Order (with rationale)
|
||||
|
||||
The three files are refactored **in dependency order, leaf-first**, so that each step has a stable foundation and any cross-file regression is caught immediately:
|
||||
|
||||
1. **Phase 1 — `src/services/acp/bridge.ts`** (leaf-ish utility module).
|
||||
- Rationale: `agent.ts` imports `forwardSessionUpdates`, `replayHistoryMessages`, `ToolUseCache` from `bridge.js`. Splitting bridge first means agent's refactor builds against the new (identical) bridge surface. Bridge has zero imports from agent.ts, so it can be split independently.
|
||||
- The barrel `bridge/index.ts` re-exports the exact public API, so the existing `from '../bridge.js'` specifier resolves unchanged under both Bun and tsc (directory + `index.ts`).
|
||||
|
||||
2. **Phase 2 — `src/services/acp/agent.ts`** (the cohesive AcpAgent class).
|
||||
- Rationale: Depends on the now-stable bridge module. Only pure helpers and types are extracted; the class body stays intact in `AcpAgent.ts`. `bridge.test.ts`, `agent.test.ts`, `permissions.test.ts` continue to work because `from '../agent.js'` and `from '../bridge.js'` resolve to the barrels.
|
||||
|
||||
3. **Phase 3 — `packages/acp-link/src/server.ts`** (largest, most interdependent).
|
||||
- Rationale: Self-contained inside `acp-link`; does not import from `src/services/acp`. Done last so the most complex module split (12 sub-files, runtime-state container, handler fan-out) can leverage the workflow discipline practiced in Phases 1–2.
|
||||
|
||||
Within each phase, the internal creation order is always: **types → leaf pure helpers → mid-level helpers → handlers → dispatch → barrel → delete original**. This keeps the import graph acyclic at every intermediate commit.
|
||||

|

### Files, responsibilities, line budgets
|
||||
|
||||
| File | Responsibility | Exports | Budget |
|
||||
|------|----------------|---------|-------:|
|
||||
| `bridge/types.ts` | Shared ACP-bridge type definitions: `ToolUseCache`, `SessionUsage`, `BridgeUsage`, `Bridge*Message` interfaces, `BridgeSDKMessage` discriminated union, `ToolInfo`, `EditToolResponseHunk`, `EditToolResponse`. Re-exports SDK type-only imports (`ContentBlock`, `ToolCallContent`, `ToolCallLocation`, `ToolKind`). | 16 symbols | ~150 |
|
||||
| `bridge/paths.ts` | Pure path-normalisation helper `toAbsolutePath` used by toolInfo / toolResults / forwarding. Leaf module, no bridge-internal imports. | `toAbsolutePath` | ~20 |
|
||||
| `bridge/contentBlocks.ts` | Low-level conversion of Claude content block shapes into ACP `ContentBlock` values. `toAcpContentUpdate` wraps arrays/strings into `ToolCallContent[]` via `toAcpContentBlock`. Leaf module. | `toAcpContentUpdate`, `toAcpContentBlock` | ~150 |
|
||||
| `bridge/toolInfo.ts` | `toolInfoFromToolUse` — large switch mapping each known tool name (Agent/Task, Bash, Read, Write, Edit, Glob, Grep, WebFetch, WebSearch, TodoWrite, ExitPlanMode, default) to ACP `ToolInfo` (title, kind, content, locations). Depends on `paths.toAbsolutePath` and `../utils.js` (`toDisplayPath`). | `toolInfoFromToolUse` | ~250 |
|
||||
| `bridge/toolResults.ts` | `toolUpdateFromToolResult` (Read markdown escape, Bash console fence, Edit/Write no-op, ExitPlanMode title, default via `toAcpContentUpdate`); `toolUpdateFromEditToolResponse` (parses `structuredPatch` hunks into diff `ToolCallContent` with absolute paths). Depends on `contentBlocks` and `paths`. | `toolUpdateFromToolResult`, `toolUpdateFromEditToolResponse` | ~180 |
|
||||
| `bridge/modelUsage.ts` | `commonPrefixLength` and `getMatchingModelUsage` — pure helpers used by the forwarding loop to resolve `contextWindow` from `modelUsage` map by prefix match. Leaf module. | `commonPrefixLength`, `getMatchingModelUsage` | ~35 |
|
||||
| `bridge/notifications.ts` | Core content-block → `SessionUpdate` conversion engine. `toAcpNotifications` handles text/thinking/image/tool_use/tool_result/etc. and writes into `ToolUseCache`. `assistantMessageToAcpNotifications` and `streamEventToAcpNotifications` are thin adapters. `normalizePlanStatus` helper for TodoWrite plan mapping. Depends on `toolInfo.toolInfoFromToolUse`, `toolResults.toolUpdateFromToolResult`, and `types`. **No logger** in original — do NOT add one here. | `toAcpNotifications`, `assistantMessageToAcpNotifications`, `streamEventToAcpNotifications`, `normalizePlanStatus` | ~320 |
|
||||
| `bridge/forwarding.ts` | `nextSdkMessageOrAbort` (races async generator against `AbortSignal`); `forwardSessionUpdates` (main loop consuming `SDKMessage` stream, dispatching to notification converters, accumulating usage, mapping stop reasons); `replayHistoryMessages` (replays stored user/assistant history through `toAcpNotifications`). The module-level `const logger = console` lives here (only `forwardSessionUpdates` default branch and `replayHistoryMessages` reference `logger.debug`). Depends on `types`, `notifications`, `modelUsage`. | `nextSdkMessageOrAbort`, `forwardSessionUpdates`, `replayHistoryMessages` | ~280 |
|
||||
| `bridge/index.ts` | Barrel — see content below. | 8 re-exports | ~20 |
|
||||
|
||||
### Barrel content — `src/services/acp/bridge/index.ts`
|
||||
|
||||
```ts
|
||||
// Barrel preserving the public API of the former src/services/acp/bridge.ts.
|
||||
// Do NOT add internal-only exports here: permissions.test.ts snapshots the
|
||||
// entire module surface via require('../bridge.ts') and would break if the
|
||||
// exported name set changes.
|
||||
export type { ToolUseCache, SessionUsage } from './types.js'
|
||||
export {
|
||||
toolInfoFromToolUse,
|
||||
} from './toolInfo.js'
|
||||
export {
|
||||
toolUpdateFromToolResult,
|
||||
toolUpdateFromEditToolResponse,
|
||||
} from './toolResults.js'
|
||||
export {
|
||||
nextSdkMessageOrAbort,
|
||||
forwardSessionUpdates,
|
||||
replayHistoryMessages,
|
||||
} from './forwarding.js'
|
||||
```
|
||||
|
||||
### Phase 1 verification
|
||||
|
||||
```bash
|
||||
# After creating all sub-files and deleting bridge.ts:
|
||||
bun test src/services/acp/__tests__/bridge.test.ts
|
||||
bun test src/services/acp/__tests__/permissions.test.ts # snapshot-sensitive
|
||||
bun test src/services/acp/__tests__/agent.test.ts # imports bridge.js + agent.js
|
||||
bun run precheck # typecheck + lint + test
|
||||
```
|
||||
|
||||
### Phase 1 risk callouts
|
||||
|
||||
- **Snapshot sensitivity**: `permissions.test.ts` lines 34–35 do `require('../bridge.ts')` and snapshot every named export. The barrel MUST export exactly `{ ToolUseCache, SessionUsage, toolInfoFromToolUse, toolUpdateFromToolResult, toolUpdateFromEditToolResponse, nextSdkMessageOrAbort, forwardSessionUpdates, replayHistoryMessages }`. Do NOT re-export `ToolInfo`, `BridgeSDKMessage`, or any internal helper.
|
||||
- **Logger alias**: the original `const logger = console` is a top-level const with no runtime side effect. Keep it ONLY in `forwarding.ts`. Do NOT create a shared `logger.ts` (would risk a cycle) and do NOT give `notifications.ts` its own logger (the original does not reference one).
|
||||
- **`ToolInfo` stays internal**: it is the return type of `toolInfoFromToolUse` but was never exported from the original `bridge.ts`. Keep it module-internal so the public surface matches the original exactly.

|

### Files, responsibilities, line budgets
|
||||
|
||||
| File | Responsibility | Exports | Budget |
|
||||
|------|----------------|---------|-------:|
|
||||
| `agent/sessionTypes.ts` | Type definitions for in-process ACP session state. `AcpSession` and `PendingPrompt` type aliases shared across agent internals and helpers. | `AcpSession`, `PendingPrompt` | ~35 |
|
||||
| `agent/permissionMode.ts` | Resolve the effective permission mode from `_meta`, settings, and process env. Determine whether ACP `bypassPermissions` mode is available (process + local opt-in + settings). `PermissionMode`-id validation guard. Imports `PermissionMode` type from `../../types/permissions.js` and `resolvePermissionMode` from `../utils.js` — leaf module, does NOT import AcpAgent. | `permissionModeIds`, `isPermissionMode`, `resolveSessionPermissionMode`, `isAcpBypassPermissionModeAvailable`, `hasOwnField` | ~110 |
|
||||
| `agent/configOptions.ts` | Build the ACP session config option list (mode + model select options) from session states. `flattenConfigOptionValues` flattens grouped/flat select options into valid value strings for validation. Imports ACP SDK types (`SessionModeState`, `SessionModelState`, `SessionConfigOption`). Leaf module. | `buildConfigOptions`, `flattenConfigOptionValues` | ~70 |
|
||||
| `agent/promptQueue.ts` | Pending-prompt queue management: `popNextPendingPrompt`, `compactPendingQueue` (compacts queue head to bound memory). Pure helpers operating on `AcpSession.pendingQueue` / `pendingMessages`. Imports `sessionTypes` only. | `popNextPendingPrompt`, `compactPendingQueue` | ~45 |
|
||||
| `agent/AcpAgent.ts` | The `AcpAgent` class implementing the ACP Agent interface. All protocol method handlers (`initialize`, `authenticate`, `newSession`, `resumeSession`, `loadSession`, `listSessions`, `forkSession`, `closeSession`, `prompt`, `cancel`, `setSessionMode`, `setSessionModel`, `setSessionConfigOption`) and private lifecycle helpers (`createSession`, `getOrCreateSession`, `teardownSession`, `replaySessionHistory`, `applySessionMode`, `updateConfigOption`, `syncSessionConfigState`, `sendAvailableCommandsUpdate`, `scheduleAvailableCommandsUpdate`, `maybeEmitSessionInfoUpdate`, `getSetting`). Imports `sessionTypes`, `permissionMode`, `configOptions`, `promptQueue`. Imports `ToolUseCache`, `forwardSessionUpdates`, `replayHistoryMessages` from `../bridge.js` (the Phase 1 barrel). | `AcpAgent` | ~480 |
|
||||
| `agent/index.ts` | Barrel — see content below. | `AcpAgent` | ~5 |
|
||||
|
||||
### Barrel content — `src/services/acp/agent/index.ts`
|
||||
|
||||
```ts
|
||||
// Barrel preserving the public API of the former src/services/acp/agent.ts.
|
||||
// Tests import AcpAgent via '../agent.js' (Bun/tsc resolve the directory's
|
||||
// index.ts). Keep this file to a single re-export.
|
||||
export { AcpAgent } from './AcpAgent.js'
|
||||
```
|
||||
|
||||
### Why the class body is NOT split further
|
||||
|
||||
The `AcpAgent` class is a single cohesive unit bound by `this.sessions` and `this.conn`. Methods like `createSession`, `prompt`, `cancel`, `teardownSession`, `applySessionMode`, `updateConfigOption` all reference `this.*` and shared private helpers. Extracting methods to a separate module would require passing the session map and connection as parameters and would create tight bidirectional coupling with high cycle risk. Therefore the class body stays in one module (~480 lines, under the 500 limit); only pure helpers and types are extracted. This keeps the import graph strictly acyclic: `sessionTypes`/`permissionMode`/`configOptions`/`promptQueue` are pure leaves that never import `AcpAgent`.
|
||||
|
||||
### Phase 2 verification
|
||||
|
||||
```bash
|
||||
bun test src/services/acp/__tests__/agent.test.ts # imports ../agent.js + ../bridge.js
|
||||
bun test src/services/acp/__tests__/permissions.test.ts # still green after bridge split
|
||||
bun run precheck
|
||||
```
|
||||
|
||||
### Phase 2 risk callouts
|
||||
|
||||
- **Private method coupling**: keep the class intact in `AcpAgent.ts`; do not be tempted to extract methods even if the file approaches the budget.
|
||||
- **ToolUseCache shape coupling**: `maybeEmitSessionInfoUpdate` attaches `__sessionInfoTitleSent` to `session.toolUseCache` via a structural cast. Keep that logic inside `AcpAgent.ts` so no cross-module dependency on the extended shape is introduced.
|
||||
- **Test path stability**: `agent.test.ts` line 195 does `await import('../agent.js')`. With `agent/index.ts` re-exporting `AcpAgent` from `agent/AcpAgent.ts`, the specifier resolves under Bun/TS because directory imports map to `index.ts`. The barrel MUST use the `.js` extension (`export { AcpAgent } from './AcpAgent.js'`) to match the project's ESM convention.

### Files, responsibilities, line budgets
|
||||
|
||||
| File | Responsibility | Exports | Budget |
|
||||
|------|----------------|---------|-------:|
|
||||
| `server/types.ts` | Shared protocol/state type definitions used across all server modules (`ServerConfig`, `PendingPermission`, `PromptCapabilities`, `SessionModelState`, `AgentCapabilities`, `ClientState`, `ContentBlock`, `PermissionResponsePayload`, `ProxyMessage`); `createClientState` factory; `DEFAULT_CLIENT_INFO` / `DEFAULT_CLIENT_CAPABILITIES` constants; JSON-RPC error code constants. | 16 symbols | ~200 |
|
||||
| `server/runtime-state.ts` | Module-scoped mutable state container for the running server: holds the `clients` Map, server config fields (`AGENT_*`, `SERVER_*`, `AUTH_TOKEN`, `DEFAULT_PERMISSION_MODE`), `rcsUpstream`, loggers, and accessor/mutator helpers. `createRelayWs` virtual `WSContext` factory. `generateRequestId` helper. **MUST NOT import any handler module** to avoid cycles. | `clients`, `getServerConfig`, `setServerConfig`, `getRcsUpstream`, `setRcsUpstream`, `getAgentConfig`, `getDefaultPermissionMode`, `setDefaultPermissionMode`, `logWs`, `logAgent`, `logSession`, `logPrompt`, `logPerm`, `logRelay`, `logServer`, `PERMISSION_TIMEOUT_MS`, `HEARTBEAT_INTERVAL_MS`, `createRelayWs`, `generateRequestId` | ~140 |
|
||||
| `server/client-send.ts` | Outbound message framing: `send`, `sendJsonRpcRaw`, `sendJsonRpcError`. `LEGACY_NOTIFICATION_TO_JSONRPC` mapping. Depends on `runtime-state` (`clients`, `rcsUpstream`) and `types` (`ClientState`). Reads `rcsUpstream` via runtime-state and the `clients` Map; `sendJsonRpcError` reads/writes `state.pendingJsonRpc`. | `send`, `sendJsonRpcRaw`, `sendJsonRpcError` | ~110 |
|
||||
| `server/acp-client.ts` | `createClient(ws, clientState)`: builds the `acp.Client` implementation that forwards `requestPermission` / `sessionUpdate` / `readTextFile` / `writeTextFile`. `handlePermissionResponse` and `cancelPendingPermissions`. Depends on `client-send` (`send`) and `runtime-state` (`logPerm`). Import graph: `client-send → runtime-state` (ok), `acp-client → client-send + runtime-state` (ok, no cycle). | `createClient`, `handlePermissionResponse`, `cancelPendingPermissions` | ~110 |
|
||||
| `server/payload-decode.ts` | Pure validation/decode utilities (`isRecord`, `optionalString`, `optionalStringField`, `payloadRecord`, `optionalPayloadRecord`, `optionalRecord`, `decodeContentBlocks`, `decodePermissionResponsePayload`). `decodeClientMessage` switch turning a raw record into a `ProxyMessage`. Public `decodeClientWsMessage` wrapper. `decodeClientMessage` is also consumed by `start-server.ts` (RCS relay path) — keep it exported here to avoid duplication. | 10 symbols | ~200 |
|
||||
| `server/permission-mode.ts` | `ACP_LINK_PERMISSION_MODE_ALIASES` + `resolveAcpLinkPermissionMode` + public `resolveNewSessionPermissionMode`. `buildAgentEnv` helper. | `resolveNewSessionPermissionMode`, `resolveAcpLinkPermissionMode`, `ACP_LINK_PERMISSION_MODE_ALIASES`, `buildAgentEnv` | ~90 |
|
||||
| `server/handlers-agent.ts` | Agent lifecycle + connection handlers: `handleConnect` and `handleDisconnect`. Spawns the agent child process, builds the ACP `ClientSideConnection`, surfaces status. Depends on `runtime-state`, `client-send`, `acp-client`, `types`. | `handleConnect`, `handleDisconnect` | ~160 |
|
||||
| `server/handlers-session.ts` | Session-scoped handlers: `handleNewSession`, `handleListSessions`, `handleLoadSession`, `handleResumeSession`, `handleCancel`, `handleSetSessionModel`, `handlePrompt`. All operate on `clients.get(ws)` state and forward to `ClientSideConnection`. | 7 symbols | ~360 |
|
||||
| `server/dispatch.ts` | `dispatchClientMessage` (legacy envelope switch). JSON-RPC wrappers `handleJsonRpcNewSession` / `Prompt` / `ListSessions` / `LoadSession` / `ResumeSession` / `SetSessionModel` / `SetSessionMode` / `CloseSession` / `CancelRequest`. `JSONRPC_METHOD_HANDLERS` table and `dispatchJsonRpcMessage` router. The JSON-RPC wrappers live **alongside** the table in this module (no cross-module forward reference). | `dispatchClientMessage`, `dispatchJsonRpcMessage`, `JSONRPC_METHOD_HANDLERS`, `handleJsonRpcSetSessionMode`, `handleJsonRpcCloseSession`, `handleJsonRpcCancelRequest` | ~290 |
|
||||
| `server/testing-internals.ts` | `__testing` public object (`dispatchClientMessage` / `dispatchJsonRpcMessage` / `registerClient` / `getClientSessionId` / `setDefaultPermissionMode`). `assertTestingInternalsEnabled` guard gated on `ACP_LINK_TEST_INTERNALS`. Co-locate the guard with the methods that call it. | `__testing`, `assertTestingInternalsEnabled` | ~80 |
|
||||
| `server/start-server.ts` | `startServer(config)`: configures runtime-state, wires `RcsUpstreamClient` relay, builds the Hono app with `/health` and `/ws` (token validation, `onOpen` / `onMessage` / `onClose`, heartbeat), HTTPS option, startup banner, SIGINT/SIGTERM graceful shutdown. Top-level orchestrator importing from `runtime-state`, `client-send`, `acp-client`, `dispatch`, `payload-decode`. All intervals/sockets MUST be created inside `startServer` (no top-level side effects). | `startServer` | ~280 |
|
||||
| `server/index.ts` | Barrel — see content below. | 8 re-exports | ~25 |
|
||||
|
||||
### Barrel content — `packages/acp-link/src/server/index.ts`
|
||||
|
||||
```ts
|
||||
// Barrel preserving the public API of the former packages/acp-link/src/server.ts.
|
||||
//
|
||||
// Re-exports of MAX_CLIENT_WS_PAYLOAD_BYTES / isJsonRpc2Message /
|
||||
// JsonRpc2ClientMessage MUST come from '../ws-message.js' (single source of
|
||||
// truth) — do NOT route them through a split module.
|
||||
export type { ServerConfig } from './types.js'
|
||||
export {
|
||||
MAX_CLIENT_WS_PAYLOAD_BYTES,
|
||||
isJsonRpc2Message,
|
||||
} from '../ws-message.js'
|
||||
export type { JsonRpc2ClientMessage } from '../ws-message.js'
|
||||
export { decodeClientWsMessage } from './payload-decode.js'
|
||||
export { resolveNewSessionPermissionMode } from './permission-mode.js'
|
||||
export { __testing } from './testing-internals.js'
|
||||
export { startServer } from './start-server.js'
|
||||
```
|
||||
|
||||
### Phase 3 verification
|
||||
|
||||
```bash
|
||||
bun test packages/acp-link/src/__tests__/server.test.ts
|
||||
bun test packages/acp-link/src/__tests__/types.test.ts
|
||||
bun run precheck
|
||||
bun run build # confirm chunk count is sane and dist/cli.js builds
|
||||
```
|
||||
|
||||
### Phase 3 risk callouts
|
||||
|
||||
- **Module-scoped mutable state**: `AGENT_COMMAND`, `AGENT_ARGS`, `AGENT_CWD`, `SERVER_PORT`, `SERVER_HOST`, `AUTH_TOKEN`, `DEFAULT_PERMISSION_MODE`, the `clients` Map, and `rcsUpstream` all live in `runtime-state.ts`. Every other module accesses them via the accessors/setters. Keep `runtime-state.ts` free of any handler import — it is the shared leaf that everything else depends on; importing handlers back into it creates a cycle.
|
||||
- **Single-flight invariant**: `sendJsonRpcError` reads/writes `state.pendingJsonRpc`. Do not parallelise handlers — the pendingJsonRpc invariant depends on serial mutation of `ClientState`.
|
||||
- **JSON-RPC wrappers co-located with the table**: `JSONRPC_METHOD_HANDLERS` references the `handleJsonRpc*` wrappers. To avoid cross-module forward references, the wrappers and the table MUST live in the same `dispatch.ts` module.
|
||||
- **Re-exports stay at source**: `MAX_CLIENT_WS_PAYLOAD_BYTES`, `isJsonRpc2Message`, `JsonRpc2ClientMessage` are re-exported from `'../ws-message.js'` directly. Do NOT re-export them from a split module.
|
||||
- **No top-level side effects**: the original file only declares module-scoped vars; loggers are created eagerly via `createLogger` (acceptable — pure construction). Do NOT start intervals or open sockets at module top level; keep them inside `startServer`.
|
||||
- **assertTestingInternalsEnabled gating**: the guard is gated on `ACP_LINK_TEST_INTERNALS` and is called by every `__testing` method. Co-locate it with `__testing` in `testing-internals.ts` and preserve the gating behavior verbatim.
|
||||
- **Biome lint surface**: 42 rules are disabled for decompiled code. Moving helpers like `optionalStringField` into their own module may surface `noUnusedVariables` if they are not re-exported. Export every helper that was previously file-local but is now cross-module, and run `bun run precheck` to catch new warnings.
|
||||
|
||||

|
||||
|
||||
## Cross-cutting verification (run after ALL three phases)
|
||||
|
||||
```bash
|
||||
# 1. Full type + lint + test gate (REQUIRED zero errors per CLAUDE.md)
|
||||
bun run precheck
|
||||
|
||||
# 2. Targeted regression runs for the three refactored modules
|
||||
bun test packages/acp-link/src/__tests__/server.test.ts
|
||||
bun test src/services/acp/__tests__/bridge.test.ts
|
||||
bun test src/services/acp/__tests__/agent.test.ts
|
||||
bun test src/services/acp/__tests__/permissions.test.ts
|
||||
|
||||
# 3. Build sanity (new chunks are produced for the new sub-files)
|
||||
bun run build
|
||||
ls dist/chunks | wc -l # expect a modest increase over the previous count
|
||||
|
||||
# 4. Unused-export audit (catches accidentally-leaked internal exports)
|
||||
bun run check:unused
|
||||
```
|
||||
|
||||
## Acceptance criteria
|
||||
|
||||
- [ ] `bun run precheck` passes with zero errors.
|
||||
- [ ] All four target test files pass unmodified.
|
||||

# Ripgrep System Fallback Implementation Plan
|
||||
|
||||
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
|
||||
|
||||
**Goal:** Make `getRipgrepConfig()` automatically fall back to system `rg` on `PATH` when the builtin/bundled ripgrep is missing (e.g. on Android/Termux), and surface the fallback via `/doctor` plus a one-time startup warning.
|
||||
|
||||
**Architecture:** Add an `existsSync` check on the builtin rg path before returning it. If missing, query `findExecutable('rg', [])`; if found, use system rg with a new human-readable `note` field on `RipgrepConfig` / `getRipgrepStatus()`. Consumers (`/doctor`, startup) read `note` and render it. No new modes — `mode` stays `'system' | 'builtin' | 'embedded'`; `note` carries the fallback narrative.
|
||||
|
||||
**Tech Stack:** TypeScript, Bun runtime, `bun:test`, Biome, lodash `memoize`.
|
||||
|
||||
**Spec:** `docs/superpowers/specs/2026-06-15-ripgrep-system-fallback-design.md`
|
||||
|
||||
---
|
||||
|
||||
## File Structure
|
||||
|
||||
- **Modify** `src/utils/ripgrep.ts` — extend `RipgrepConfig` type with `note?`; extend internal `ripgrepStatus` singleton with `note?`; extend `getRipgrepStatus()` return type with `note?`; rewrite the `builtin` branch of `getRipgrepConfig()` to add `existsSync` + system-rg fallback; sync `note` into the singleton inside `testRipgrepOnFirstUse`.
|
||||
- **Create** `src/utils/__tests__/ripgrepConfig.test.ts` — five-branch decision coverage for `getRipgrepConfig()`.
|
||||
- **Modify** `src/utils/doctorDiagnostic.ts` — propagate `note` from `getRipgrepStatus()` into the diagnostic object.
|
||||
- **Modify** `src/screens/Doctor.tsx` — render `note` in the `Search:` line.
|
||||
- **Modify** `src/entrypoints/init.ts` — emit a one-time stderr warning when `note` is set.
|
||||
|
||||
Each file has a single clear responsibility and changes stay inside that file's existing role.
|
||||
|
||||
---
|
||||
|
||||
## Task 1: Extend types with optional `note` field (no behavior change)
|
||||
|
||||
**Files:**
|
||||
- Modify: `src/utils/ripgrep.ts:22-27` (type), `:29-63` (function — minimal shape only), `:523-527` (singleton), `:533-544` (public getter)
|
||||
|
||||
This task only adds the optional field everywhere it's needed and populates it with `undefined` for existing branches. Behavior stays identical. Task 2 fills in the real values.
|
||||
|
||||
- [ ] **Step 1: Extend `RipgrepConfig` type**
|
||||
|
||||
File: `src/utils/ripgrep.ts`, replace lines 22-27.
|
||||
|
||||
```ts
|
||||
type RipgrepConfig = {
|
||||
mode: 'system' | 'builtin' | 'embedded'
|
||||
command: string
|
||||
args: string[]
|
||||
argv0?: string
|
||||
note?: string
|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Step 2: Extend the `ripgrepStatus` singleton shape**
|
||||
|
||||
File: `src/utils/ripgrep.ts`, replace lines 522-527.
|
||||
|
||||
```ts
|
||||
// Singleton to store ripgrep availability status
|
||||
let ripgrepStatus: {
|
||||
working: boolean
|
||||
lastTested: number
|
||||
config: RipgrepConfig
|
||||
note?: string
|
||||
} | null = null
|
||||
```
|
||||
|
||||
- [ ] **Step 3: Extend `getRipgrepStatus()` return type**
|
||||
|
||||
File: `src/utils/ripgrep.ts`, replace lines 533-544.
|
||||
|
||||
```ts
|
||||
/**
|
||||
* Get ripgrep status and configuration info
|
||||
* Returns current configuration immediately, with working status if available
|
||||
*/
|
||||
export function getRipgrepStatus(): {
|
||||
mode: 'system' | 'builtin' | 'embedded'
|
||||
path: string
|
||||
working: boolean | null // null if not yet tested
|
||||
note?: string
|
||||
} {
|
||||
const config = getRipgrepConfig()
|
||||
return {
|
||||
mode: config.mode,
|
||||
path: config.command,
|
||||
working: ripgrepStatus?.working ?? null,
|
||||
note: ripgrepStatus?.note ?? config.note,
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Step 4: Verify typecheck**
|
||||
|
||||
Run: `bunx tsc --noEmit`
|
||||
Expected: 0 errors. (All `note` fields are optional; existing code is unaffected.)
|
||||
|
||||
- [ ] **Step 5: Commit**
|
||||
|
||||
```bash
|
||||
git add src/utils/ripgrep.ts
|
||||
git commit -m "refactor: add optional note field to RipgrepConfig and getRipgrepStatus"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Task 2: Implement fallback decision in `getRipgrepConfig()` (TDD)
|
||||
|
||||
**Files:**
|
||||
- Modify: `src/utils/ripgrep.ts:1-20` (imports), `:56-63` (builtin branch)
|
||||
- Test: `src/utils/__tests__/ripgrepConfig.test.ts`
|
||||
|
||||
- [ ] **Step 1: Write the failing test file**
|
||||
|
||||
Create `src/utils/__tests__/ripgrepConfig.test.ts` with this exact content:
|
||||
|
||||
```ts
|
||||
import { afterEach, beforeEach, describe, expect, mock, test } from 'bun:test'

|

Run: `bun test src/utils/__tests__/ripgrepConfig.test.ts`
|

Expected: The fourth and fifth tests FAIL — currently `getRipgrepConfig()` returns `mode='builtin'` with no `note` when the builtin path is missing, instead of falling back to system rg.
|
||||
|
||||
- [ ] **Step 3: Add `existsSync` import to `ripgrep.ts`**
|
||||
|
||||
File: `src/utils/ripgrep.ts`, replace lines 1-2.
|

import { execFile, spawn } from 'child_process'
|
||||
import { existsSync } from 'fs'
|
||||
```
|
||||
|
||||
- [ ] **Step 4: Rewrite the builtin branch with fallback logic**
|
||||
|
||||
File: `src/utils/ripgrep.ts`, replace lines 56-63.
|
||||
|
||||
```ts
|
||||
const rgRoot = path.resolve(__dirname, 'vendor', 'ripgrep')
|
||||
const command =
|
||||
process.platform === 'win32'
|
||||
? path.resolve(rgRoot, `${process.arch}-win32`, 'rg.exe')

- [ ] **Step 6: Run full precheck to ensure no regression**
|

## Task 3: Sync `note` into the singleton inside `testRipgrepOnFirstUse`
|
||||
|
||||
**Files:**
|
||||
- Modify: `src/utils/ripgrep.ts:549-615`
|
||||
|
||||
Currently `testRipgrepOnFirstUse` writes `ripgrepStatus = { working, lastTested, config }` without `note`. The new `getRipgrepStatus()` in Task 1 already falls back to `config.note` if the singleton has none, so this task is mostly belt-and-suspenders: persist the note explicitly so consumers reading the singleton directly also see it.
|
||||
|
||||
- [ ] **Step 1: Update the success-path assignment**
|
||||
|
||||
File: `src/utils/ripgrep.ts`, replace lines 592-596.
|
||||
|
||||
```ts
|
||||
ripgrepStatus = {
|
||||
working,
|
||||
lastTested: Date.now(),
|
||||
config,
|
||||
note: config.note,
|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Step 2: Update the catch-path assignment**
|
||||
|
||||
File: `src/utils/ripgrep.ts`, replace lines 608-612.
|
||||
|
||||
```ts
|
||||
ripgrepStatus = {
|
||||
working: false,
|
||||
lastTested: Date.now(),
|
||||
config,
|
||||
note: config.note,
|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Step 3: Run precheck**
|
||||
|
||||
Run: `bun run precheck`
|
||||
Expected: 0 errors.
|

- [ ] **Step 4: Commit**
|

- [ ] **Step 1: Extend the diagnostic object**
|

File: `src/utils/doctorDiagnostic.ts`, replace lines 588-597.
|

```ts
|

// Get ripgrep status and configuration info
|

const ripgrepStatusRaw = getRipgrepStatus()
|
||||
|
||||
// Provide simple ripgrep status info
|

working: ripgrepStatusRaw.working ?? true, // Assume working if not yet tested
|

Run: `bun run precheck`
|

Expected: 0 errors.

- [ ] **Step 4: Manual smoke check (optional)**
|

Run: `bun run dev -- doctor 2>&1 | grep -i search`

Expected: prints the `Search:` line; on dev machine `note` should be empty so no `Note:` line appears.

- [ ] **Step 1: Add the warning right before `profileCheckpoint('init_function_end')`**
|

File: `src/entrypoints/init.ts`, replace lines 240-243.
|
||||
|

```ts
|

```
|

|

- [ ] **Step 2: Run precheck**
|

Expected: 0 errors.
|

|

- [ ] **Step 3: Manual smoke check**
|

Run: `bun run dev -- --version`
|

Expected: `[ripgrep]` line does NOT appear on stderr.
|

**Files:** None (verification only)
|

- [ ] **Step 1: Run full precheck**
|

Run: `bun test src/utils/__tests__/ripgrepConfig.test.ts`

Expected: PASS (5/5).
|

|

|

## Self-Review Notes
|
||||
|
||||
**Spec coverage:**
|
||||
- Decision chain with 5 branches → Task 2 ✓
|
||||
- `note` field on `RipgrepConfig` / singleton / `getRipgrepStatus()` → Tasks 1, 3 ✓
|
||||
- `/doctor` rendering → Task 4 ✓
|
||||
- Startup warning → Task 5 ✓
|
||||
- Tests for 5 branches → Task 2 Step 1 ✓
|
||||
- Acceptance criteria 1-5 cross-checked against spec section "Acceptance Criteria"
|
||||
|
||||
**Placeholder scan:** None. Each step contains the exact code or command.
|
||||
|
||||
**Type consistency:** `note?: string` consistently used across `RipgrepConfig`, `ripgrepStatus` singleton, `getRipgrepStatus()` return, `doctorDiagnostic.ripgrepStatus.note`. In Doctor.tsx the diagnostic object's `note` is `string | null` (Task 4 Step 1 uses `?? null`), accessed with a truthy check (`{note && ...}`) which handles both `null` and `undefined`.
|
||||
|
||||
**Mock hygiene note:** Task 2's test mocks `node:fs`, `src/utils/which.ts`, `src/utils/bundledMode.ts`, `src/utils/envUtils.ts`, `src/utils/distRoot.ts`, `os`, and `lodash-es/memoize.js`. These are process-global mocks (Bun limitation — see project CLAUDE.md "Mock 使用规范"). The test file lives at `src/utils/__tests__/ripgrepConfig.test.ts` and there is no existing `ripgrep.test.ts` to collide with, so no contamination risk.

# Ripgrep System Fallback — Design
|
||||
|
||||
**Date:** 2026-06-15
|
||||
**Status:** Approved (pending spec review)
|
||||
**Topic:** Make ripgrep gracefully degrade to system `rg` when the bundled/builtin binary is unavailable on the current platform (e.g. Android/Termux).
|
||||
|
||||
## Problem
|
||||
|
||||
`src/utils/ripgrep.ts` `getRipgrepConfig()` has three resolution branches:
|
||||
|
||||
1. `USE_BUILTIN_RIPGREP=0` → look up `rg` on `PATH`
|
||||
2. `isInBundledMode()` → bun-internal embedded rg
|
||||
3. Otherwise → `vendor/ripgrep/<arch>-<platform>/rg` (builtin)
|
||||
|
||||
On Android/Termux, all three fail:
|
||||
|
||||
- The user has not opted into system rg.
|
||||
- Bun does not publish Android builds, so `isInBundledMode()` is false.
|
||||
- `scripts/postinstall.cjs:81` throws `Unsupported platform: android`, so no builtin binary is ever downloaded. `vendor/ripgrep/` contains no `arm64-android` directory.
|
||||
|
||||
Net effect: spawn of a nonexistent path → `ENOENT` → user sees "ripgrep 缺失" with no recovery path other than manually setting `USE_BUILTIN_RIPGREP=0`. The discovery pipeline (`Grep`/`Glob` tools, file suggestions, hooks) all fail in the same way.
|
||||
|
||||
More generally, the same breakage occurs on any platform where the builtin binary is missing for any reason (incomplete install, custom platform, deleted vendor directory). The current code has no graceful degradation.
|
||||
|
||||
## Goals
|
||||
|
||||
- On any platform, when the builtin/bundled ripgrep is unavailable, automatically fall back to `rg` on `PATH`.
|
||||
- Surface the fallback clearly to the user via `/doctor` and a one-line startup warning, so they understand why they are not on the bundled rg and what to do if the system rg is also missing.
|
||||
- Do not change behavior on platforms where the builtin rg works (macOS, Linux, Windows).
|
||||
|
||||
## Non-Goals
|
||||
|
||||
- Downloading or shipping an Android-native ripgrep binary.
|
||||
- Adding a REPL persistent status indicator.
|
||||
- Touching `USE_BUILTIN_RIPGREP` semantics for users who already opt into system rg.
|
||||
- Modifying build / `postinstall.cjs` platform mapping.
|
||||
|
||||
## Design
|
||||
|
||||
### Decision chain (`getRipgrepConfig`)
|
||||
|
||||
The function gains an existence check and a system-rg fallback. The order of existing branches is preserved.
|
||||
|
||||
```
|
||||
1. USE_BUILTIN_RIPGREP=0 (user-opt) → system rg mode='system' note=undefined
|
||||
2. isInBundledMode() → bun embedded rg mode='embedded' note=undefined
|
||||
3. Compute builtin path; existsSync(rgPath)?
|
||||
✓ true → builtin rg mode='builtin' note=undefined
|
||||
✓ false → findExecutable('rg', [])
|
||||
✓ found → system rg (auto fallback) mode='system' note='fallback: builtin rg unavailable on <platform>, using system rg'
|
||||
✗ missing → keep builtin path (let upper layer ENOENT) mode='builtin' note='no ripgrep available on <platform>; install via apt/pkg/brew/...'
|
||||
```
|
||||
|
||||
Rationale for the missing-system-rg branch returning the (nonexistent) builtin path: it preserves the historical spawn behavior so existing error-handling paths in `ripGrepRaw` and callers continue to see `ENOENT`. The new `note` field carries the human-readable explanation; the spawn itself still fails the same way.
|
||||
|
||||
`existsSync` is a single synchronous syscall; `getRipgrepConfig` is already memoized via lodash, so the cost is paid once per process.
|
||||
|
||||
### Status API (`getRipgrepStatus`)
|
||||
|
||||
```ts
|
||||
type RipgrepStatus = {
|
||||
mode: 'system' | 'builtin' | 'embedded' // unchanged
|
||||
path: string // unchanged
|
||||
working: boolean | null // unchanged
|
||||
note?: string // NEW — human-readable hint
|
||||
}
|
||||
```
|
||||
|
||||
The internal `ripgrepStatus` singleton also gains `note?: string`. `testRipgrepOnFirstUse` propagates the note from the active config.
|
||||
|
||||
The `note` value is sourced from `getRipgrepConfig()` (the source of truth), so the API remains a single read; no second lookup.
|
||||
|
||||
### UI — `/doctor`
|
||||
|
||||
`src/screens/Doctor.tsx` renders the existing `Search:` line plus the note when present. Two example outputs:
|
||||
|
||||
```
|
||||
Search: OK (system rg fallback — builtin ripgrep unavailable on android)
|
||||
Search: Not working (no ripgrep available on android — install via apt/pkg/brew)
|
||||
```
|
||||
|
||||
`src/utils/doctorDiagnostic.ts` extends the `ripgrepStatus` object it returns to include `note`.
|
||||
|
||||
### UI — startup warning
|
||||
|
||||
A single check near the end of `src/entrypoints/init.ts` reads `getRipgrepStatus()`. If `note` is set, it writes one line to stderr:
|
||||
|
||||
```
|
||||
[ripgrep] fallback: builtin rg unavailable on android, using system rg
|
||||
```
|
||||
|
||||
Constraints:
|
||||
- Non-blocking — does not throw or exit.
|
||||
- Fires at most once per process (memoized config + idempotent init).
|
||||
- Goes to stderr so it does not corrupt pipe mode (`-p`) stdout.
|
||||
- No retry, no telemetry beyond existing `tengu_ripgrep_availability`.
|
||||
|
||||
### Testing
|
||||
|
||||
New test file `src/utils/__tests__/ripgrepDecision.test.ts` (or extend an existing one) covers the five branches:
|
||||
|
||||
1. `USE_BUILTIN_RIPGREP=0` and `rg` on PATH → `mode='system'`, `note=undefined`.
|
||||
2. `isInBundledMode()` → `mode='embedded'`, `note=undefined`.
|
||||
3. Builtin path exists → `mode='builtin'`, `note=undefined`.
|
||||
4. Builtin path missing, `rg` on PATH → `mode='system'`, `note` set.
|
||||
5. Builtin path missing, `rg` not on PATH → `mode='builtin'`, `note` set (path is the nonexistent builtin path).
|
||||
|
||||
Mocks: `existsSync` (via `fs` module), `findExecutable`, `isInBundledMode`, `process.env.USE_BUILTIN_RIPGREP`, `process.platform`. Follow the project's mock conventions (see `tests/mocks/`); no business-module mocking.
|
||||
|
||||
Existing `doctorDiagnostic` tests: extend to assert `note` is propagated; update any snapshots.
|
||||
|
||||
## Risks
|
||||
|
||||
- **Behavior preservation on supported platforms:** the `existsSync` check only changes the path when the builtin file is genuinely absent. On macOS/Linux/Windows the builtin binary always exists post-install, so the decision chain resolves to `mode='builtin'` exactly as today. Verified by the test for branch 3.
|
||||
- **`note` field addition is backward-compatible:** optional field; existing consumers ignore it.
|
||||
- **Memoization:** `getRipgrepConfig` is memoized for the process lifetime. If a user installs ripgrep mid-session, the fallback will not trigger until restart. Acceptable — matches existing behavior for `USE_BUILTIN_RIPGREP` changes.
|
||||
- **Platform string in `note`:** uses `process.platform` directly (`'android'`, `'linux'`, `'darwin'`, `'win32'`). No translation; the message is diagnostic, not user-facing marketing copy.
|
||||
|
||||
## Out of Scope (YAGNI)
|
||||
|
||||
- Android prebuilt binary download.
|
||||
- Persistent REPL status indicator.
|
||||
- Build-time vendor changes.
|
||||
- Telemetry beyond what `testRipgrepOnFirstUse` already emits.
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
- On a platform where the builtin rg binary is missing and `rg` is on `PATH`, `getRipgrepStatus()` returns `mode='system'`, `path=<resolved system rg>`, `note` set to a non-empty human-readable string.
|
||||
- On a platform where neither builtin nor system rg is available, `/doctor` displays `Not working` plus the install hint.
|
||||
- The startup warning fires exactly once per session when `note` is set.
|
||||
- All existing ripgrep tests pass unchanged on macOS/Linux dev machines.
|
||||
- `bun run precheck` is green.

|

* ACP Agent implementation — bridges ACP protocol methods to Claude Code's
|
||||
* internal QueryEngine / query() pipeline.
|
||||
*
|
||||
* Architecture: Uses internal QueryEngine (not @anthropic-ai/claude-agent-sdk)
|
||||
* to directly run queries, with a bridge layer converting SDKMessage → ACP SessionUpdate.
|
||||
*
|
||||
* NOTE: The AcpAgent class is split across three modules for line-budget reasons.
|
||||
* The class shell + lightweight protocol handlers live here; the heavy
|
||||
* session-lifecycle methods (createSession / getOrCreateSession /
|
||||
* replaySessionHistory / teardownSession / applySessionMode / updateConfigOption)
|
||||
* are attached to the prototype in `./sessionLifecycle.js`, and the prompt
|
||||
* flow (prompt / setSessionConfigOption) in `./promptFlow.js`. The barrel
|
||||
* `./index.js` imports those side-effect modules so the prototype is fully
|
||||
* populated before any AcpAgent instance is constructed.
