codex_lead_cc

codex_lead_cc is a Codex-to-Claude-Code Interactive Bridge.

It runs one Codex Lead, one local CC Bridge, and one long-lived Claude Code PTY. Codex starts in supervisor_home; Claude Code is the only process that enters the real project directory.

User starts codex_lead_cc in a real project
  -> wrapper creates supervisor_home and a session
  -> wrapper captures local Claude Code env
  -> wrapper starts one long-lived Claude Code PTY
  -> wrapper starts Codex with cwd = supervisor_home
  -> Codex uses cc-send / cc-input / cc-status
  -> Claude Code performs all real project work

This project does not use MCP, subagents, TaskFiles, delegate, submit, daemon, workers, queues, OperationRequest, TaskContract, or PermissionContract in the main path.

Install

npm install -g --install-links=true git+https://github.com/zake-cn/codex_lead_cc.git
codex_lead_cc --doctor

Development

git clone https://github.com/zake-cn/codex_lead_cc.git
cd codex_lead_cc
npm install
npm run build
npm link
codex_lead_cc --doctor

Usage

codex_lead_cc [codex args...]
codex_lead_cc cc-send [--timeout-sec 120] [--stream] "prompt"
codex_lead_cc cc-input --key <1|2|3|enter|escape|ctrl-c> [--stream]
codex_lead_cc cc-status
codex_lead_cc migrate-supervisor
codex_lead_cc update
codex_lead_cc config show | reset | path
codex_lead_cc --doctor

cc-send, cc-input, and cc-status must run inside a Codex session launched by codex_lead_cc.

File IPC

Each session owns a bridge directory:

session_dir/
  bridge/
    inbox/
    streams/
    results/
    state.json
    bridge.log

cc-send writes bridge/inbox/<request_id>.json, waits for bridge/results/<request_id>.json, then prints the final clean output and status footer. It does not print intermediate PTY output by default; --stream enables the clean debug stream.

cc-input uses the same blocking output path, but sends one key to the PTY.

cc-status only reads bridge/state.json; it does not drive Claude Code execution.

Status Footer

<<<CODEX_LEAD_CC_STATUS>>>
{"status":"completed"}
<<<CODEX_LEAD_CC_STATUS_END>>>

Permission request:

<<<CODEX_LEAD_CC_STATUS>>>
{"status":"needs_permission","suggested_keys":["1","2","3"]}
<<<CODEX_LEAD_CC_STATUS_END>>>

No effective output after submit:

<<<CODEX_LEAD_CC_STATUS>>>
{"status":"not_submitted","error":"Prompt appears to remain in Claude Code input box; no effective output was observed."}
<<<CODEX_LEAD_CC_STATUS_END>>>

Completion

<<<CODEX_LEAD_CC_DONE>>> is only an auxiliary marker. The main completion decision uses PTY screen state:

• no new output for quiet_ms
• no loading or spinner in bottom lines
• no permission menu
• runtime is at least min_run_ms
• effective output was observed after submit

Defaults:

{
  "min_run_ms": 1500,
  "quiet_ms": 2500,
  "spinner_stable_ms": 1000,
  "check_interval_ms": 100,
  "submit_grace_ms": 5000
}

Claude Code is usually input-ready, so input readiness is not used as task completion.
Input echo alone is not effective output; it returns not_submitted instead of completed.

Permission Loop

When Claude Code asks for permission, Codex asks the human which option to grant.

• option 1: Codex runs codex_lead_cc cc-input --key 1
• option 2: Codex records reusable policy for itself, but still runs codex_lead_cc cc-input --key 1
• option 3: Codex runs codex_lead_cc cc-input --key 3

Only send --key 2 when the human explicitly asks Claude Code itself to stop asking.

Human grants reusable policy to Codex. Codex grants one-shot approval to Claude Code.

Supervisor Migration

Normal codex_lead_cc startup creates missing CLAUDE.md, AGENTS.md, and MEMORY.md in supervisor_home, but it does not overwrite existing files. If the supervisor rules are stale, startup prints:

Supervisor rules are stale. Run: codex_lead_cc migrate-supervisor

Run this to force migration:

codex_lead_cc migrate-supervisor

update runs supervisor migration after a successful install/build.

Session Schema

Session files use version 2:

{
  "version": 2,
  "session_id": "...",
  "project_path": "...",
  "supervisor_home": "...",
  "session_dir": "...",
  "artifact_root": "...",
  "bridge_dir": "...",
  "bridge_state_file": "...",
  "claude_env_file": "...",
  "bridge_pid": 123,
  "cc_pid": 456,
  "created_at": "..."
}

Requirements

• Node.js >= 20
• codex on PATH
• claude on PATH, or configured via claude_runtime.command
• git on PATH
• node-pty is a runtime dependency and required for the interactive Claude Code bridge
• script on PATH only for explicit debug fallback with CODEX_LEAD_CC_ALLOW_PTY_FALLBACK=1
