Twelve actionable items (7 Major + 5 Minor) from the CodeRabbit review on claude-code-best/claude-code#386: - docs/internals/autonomy-jira.md: typo "due input close" → "due to input close". - src/utils/autonomyRuns.ts: - selectPersistedAutonomyRuns no longer evicts active (queued/running) runs when the combined list exceeds AUTONOMY_RUNS_MAX. Active runs are kept in full and the inactive history is capped to the remaining budget so persisted ownership for live work survives. - isValidOwnerProcessId now allows pid <= 4_194_304 so a live run owned by the maximum Linux PID is not treated as stale. - src/utils/autonomyAuthority.ts: maskCodeFencedLines tracks the active fence length and only closes the fence when a same-character run of equal-or- greater length appears with no trailing content, so a nested ```yaml inside an outer ```` block no longer leaks fake `tasks:` entries into the parser. - src/cli/print.ts: late-shutdown branches in the cron and scheduled-task paths now call cancelQueuedAutonomyCommands({ commands: [command] }) instead of markAutonomyRunCancelled(...). Updating run state alone left the queue-side record orphaned for resume/recovery. - src/utils/processUserInput/processSlashCommand.tsx: scheduled-task-result notification is enqueued before finalizeAutonomyRunCompleted (which queues follow-up autonomy commands) so both at priority: 'later' land in order and the next autonomy step can not run before the worker's output is observed. - src/screens/REPL.tsx + src/utils/handlePromptSubmit.ts: - onQuery now returns Promise<boolean>: false from the concurrent-guard skip path, true otherwise. Other call sites use `void onQuery(...)` and are unaffected. handlePromptSubmit's onQuery prop type matches. - The autonomy-prompt callsite captures the executed flag, finalizes claim.claimedCommands as { type: 'completed' } only when onQuery actually ran, and runs the completed-finalize in its own try/catch so a failure there does not propagate into the outer catch and trigger a second finalize as { type: 'failed' } for the same commands. - Removed the unsafe `command.value as string` cast; createUserMessage already accepts `string | ContentBlockParam[]`. - createUserMessage mock in src/__tests__/handlePromptSubmit.test.ts now matches the new Promise<boolean> shape. - packages/builtin-tools/src/tools/RemoteTriggerTool/__tests__/ RemoteTriggerTool.test.ts: - Inline auth mock replaced with the shared tests/mocks/auth (added). - The full mock of src/constants/oauth.js is replaced by a narrow side-effect-only mock that overrides the env-reading helpers (getOauthConfig, fileSuffixForOauthConfig, MCP_CLIENT_METADATA_URL) and delegates pure data exports to the real module. - tests/integration/dependency-overrides.test.ts: - mermaid does not export `./package.json` in its exports map, so require.resolve('mermaid/package.json') throws ERR_PACKAGE_PATH_NOT_EXPORTED in runtimes that honor exports semantics. The test now resolves the package entry and walks up to the package root via a small findPackageJson helper. - readFileSync from node:fs is replaced with `await Bun.file(...).text()` to match the project's Bun-API requirement. Validation: - bun run typecheck (clean). - bun test → 3996 pass / 0 fail across 305 test files.

Claude Code Best V5 (CCB)
Which Claude do you like? The open source one is the best.
A reverse-engineered / decompiled source restoration of Anthropic's official Claude Code CLI tool. The goal is to reproduce most of Claude Code's functionality and engineering capabilities. It's abbreviated as CCB.
Documentation (Chinese) — PR contributions welcome.
Sponsor placeholder.
- v1: Basic runability and type checking pass
- V2: Complete engineering infrastructure
- Biome formatting may not be implemented first to avoid code conflicts
- Build pipeline complete, output runnable on both Node.js and Bun
- V3: Extensive documentation and documentation site improvements
- V4: Large-scale test suite for improved stability
- V5: Enterprise-grade monitoring/reporting, missing tools补全, restrictions removed
- Removed anti-distillation code
- Web search capability (using Bing) Docs
- Debug mode support Docs
- Disabled auto-updates
- Custom Sentry error reporting support Docs
- Custom GrowthBook support (GB is open source — configure your own feature flag platform) Docs
- Custom login mode — configure Claude models your way
- V6: Large-scale refactoring, full modular packaging
- V6 will be a new branch; main branch will be archived as a historical version
I don't know how long this project will survive. Star + Fork + git clone + .zip is the safest bet.
This project updates rapidly — Opus continuously optimizes in the background, with new changes almost every few hours.
Claude has burned over $1000, out of budget, switching to GLM to continue; @zai-org GLM 5.1 is quite capable.
Quick Start
Prerequisites
Make sure you're on the latest version of Bun, otherwise you'll run into all sorts of weird bugs. Run bun upgrade!
- Bun >= 1.3.11
Install Bun:
# Linux and macOS
curl -fsSL https://bun.sh/install | bash
# Windows (PowerShell)
powershell -c "irm bun.sh/install.ps1 | iex"
Post-installation steps:
-
Make
bunavailable in the current terminalThe installer adds
~/.bun/binto the matching shell configuration file. On macOS with the default zsh shell, you may see:Added "~/.bun/bin" to $PATH in "~/.zshrc"Restart the current shell as the installer suggests:
exec /bin/zshIf you use bash, reload the bash configuration:
source ~/.bashrcWindows PowerShell users can close and reopen PowerShell.
-
Verify that Bun is available:
bun --help bun --version -
Update to latest version (if already installed):
bun upgrade
- Standard Claude Code configuration — each provider has its own setup method
Command Execution Location
- Bun installation and checking commands can be run from any directory:
curl -fsSL https://bun.sh/install | bash,bun --help,bun --version,bun upgrade - Project dependency installation, development mode, and builds must be run from this repository root, the directory containing
package.json.
Install
cd /path/to/claude-code
bun install
Run
# Dev mode — if you see version 888, it's working
bun run dev
# Build
bun run build
The build uses code splitting (build.ts), outputting to dist/ (entry dist/cli.js + ~450 chunk files).
The build output runs on both Bun and Node.js — you can publish to a private registry and run directly.
If you encounter a bug, please open an issue — we'll prioritize it.
First-time Setup /login
After the first run, enter /login in the REPL to access the login configuration screen. Select Anthropic Compatible to connect to third-party API-compatible services (no Anthropic account required).
Fields to fill in:
| Field | Description | Example |
|---|---|---|
| Base URL | API service URL | https://api.example.com/v1 |
| API Key | Authentication key | sk-xxx |
| Haiku Model | Fast model ID | claude-haiku-4-5-20251001 |
| Sonnet Model | Balanced model ID | claude-sonnet-4-6 |
| Opus Model | High-performance model ID | claude-opus-4-6 |
- Tab / Shift+Tab to switch fields, Enter to confirm and move to the next, press Enter on the last field to save
- Model fields auto-fill from current environment variables
- Configuration saves to
~/.claude/settings.jsonunder theenvkey, effective immediately
You can also edit ~/.claude/settings.json directly:
{
"env": {
"ANTHROPIC_BASE_URL": "https://api.example.com/v1",
"ANTHROPIC_AUTH_TOKEN": "sk-xxx",
"ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-haiku-4-5-20251001",
"ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-4-6",
"ANTHROPIC_DEFAULT_OPUS_MODEL": "claude-opus-4-6"
}
}
Supports all Anthropic API-compatible services (e.g., OpenRouter, AWS Bedrock proxies, etc.) as long as the interface is compatible with the Messages API.
Feature Flags
All feature toggles are enabled via FEATURE_<FLAG_NAME>=1 environment variables, for example:
FEATURE_BUDDY=1 FEATURE_FORK_SUBAGENT=1 bun run dev
See docs/features/ for detailed descriptions of each feature. Contributions welcome.
VS Code Debugging
The TUI (REPL) mode requires a real terminal and cannot be launched directly via VS Code's launch config. Use attach mode:
Steps
-
Start inspect server in terminal:
bun run dev:inspectThis outputs an address like
ws://localhost:8888/xxxxxxxx. -
Attach debugger from VS Code:
- Set breakpoints in
src/files - Press F5 → select "Attach to Bun (TUI debug)"
- Set breakpoints in
