Codex Autopilot

Multi-model AI coding automation system with intelligent task routing and built-in CI/CD. Watchdog-driven loop that orchestrates Codex (backend) and Gemini (frontend) sessions in tmux, auto-routes tasks by type, manages context compaction, runs incremental code reviews, dispatches tasks from a priority queue, and includes a test-agent that auto-detects failures, enqueues fixes, and ratchets coverage. Use when managing multiple concurrent AI coding sessions, automating development workflows, orchestrating parallel AI-assisted coding across projects, routing frontend vs backend tasks to different models, or running continuous testing with auto-fix. Triggers: autopilot, watchdog, codex automation, tmux codex, multi-project codex, auto-nudge codex, codex session management, gemini frontend, multi-model routing, ai task routing, ci cd, test agent, coverage ratchet.

Multi-model AI coding orchestration via tmux + launchd on macOS.

Overview

Codex Autopilot runs a watchdog loop that orchestrates multiple AI coding sessions in tmux. It features intelligent task routing — frontend tasks (UI, components, H5) are routed to Gemini CLI (1M context window, superior design aesthetics), while backend tasks (API, database, deployment) go to Codex CLI. The watchdog detects idle sessions, auto-nudges them, handles permission prompts, dispatches tasks from a priority queue, and sends notifications via Discord/Telegram.

Multi-Model Architecture

Role	Model	Strengths
Backend coding	Codex (GPT-5.4)	API, database, deployment, refactoring
Frontend development	Gemini CLI	UI, components, pages, styles, 1M context
Orchestration	Claude / OpenClaw	Task routing, code review, project management

Tasks are automatically classified by keywords and routed to the appropriate model. Frontend tasks fall back to Codex if Gemini is unavailable.

Installation

bash

git clone https://github.com/imwyvern/AIWorkFlowSkill.git ~/.autopilot
cd ~/.autopilot
cp config.yaml.example config.yaml
# Edit config.yaml with your project paths, Telegram bot token, and Discord channels

Dependencies

• macOS with launchd (for scheduled execution)
• tmux — session multiplexer for Codex windows
• Codex CLI (codex) — OpenAI's coding agent
• python3 — for state cleanup and PRD verification scripts
• yq — YAML processor for config parsing
• jq — JSON processor for state management
• bash 4+ — for associative arrays in scripts

Install dependencies via Homebrew:

bash

brew install tmux yq jq

launchd Setup

Use install.sh to register the launchd plist:

bash

./install.sh

This creates a LaunchAgent that runs the watchdog on a configurable interval.

Core Components

watchdog.sh

Main loop engine. On each tick:

1. Iterates through configured project tmux windows
2. Captures current Codex output via codex-status.sh
3. Determines if session is active, idle, or stuck
4. Dispatches appropriate action (nudge, permission grant, task from queue)
5. Enforces cooldowns, daily send limits, and loop detection

codex-status.sh

Captures and analyzes tmux pane content. Detects:

• Codex activity state (working / idle / waiting for permission)
• Permission prompts requiring approval
• Context compaction signals
• Error states and crashes

tmux-send.sh

Sends keystrokes or text to a specific tmux window. Handles:

• Typing text into Codex prompt
• Pressing Enter/keys for permission approval
• Verification polling to confirm send succeeded

autopilot-lib.sh

Shared function library used by all scripts:

• Telegram notification helpers
• File locking primitives
• Timeout and retry logic
• Logging utilities
• State file read/write

autopilot-constants.sh

Defines status constants used across scripts (e.g., STATUS_ACTIVE, STATUS_IDLE, STATUS_PERMISSION).

task-queue.sh

Task queue manager. Supports:

• Enqueuing tasks for specific projects
• Dequeueing next task based on priority
• Task status tracking (pending/running/done/failed)

discord-notify.sh

Sends formatted notifications to Discord channels via webhook. Supports project-channel routing defined in config.yaml.

test-agent.sh

Built-in CI/CD that runs on every commit. Evaluates test suites, tracks coverage, and auto-enqueues bugfix tasks when tests fail.

text

commit → watchdog detects → test-agent evaluate
  ├─ all pass → review clean → enqueue coverage tasks for low-coverage files
  └─ failures → parse log → auto-enqueue "fix(test): ..." bugfix task
       └─ 1h cooldown per file (prevents retry loops)

Triggers:

• on_commit_evaluate — every new commit
• on_review_clean — after code review passes
• nightly — scheduled full evaluation (default 02:30)

Coverage ratchet: global coverage must not regress; weekly +1% target, capped at 90%.

Other Scripts

Script	Purpose
auto-nudge.sh	Nudge logic for idle Codex sessions
auto-check.sh	Periodic health check across all projects
permission-guard.sh	Auto-approve or flag permission prompts

monitor-all.sh	Dashboard: show status of all monitored projects
status-sync.sh	Sync state to status.json for external consumption
rotate-logs.sh	Log rotation and cleanup
cleanup-state.py	Remove stale entries from state.json
claude-fallback.sh	Fallback handler when Codex is unavailable
prd-audit.sh	Audit PRD completion status
prd-verify.sh / prd_verify_engine.py	Verify PRD items against codebase
codex-token-daily.py	Track daily token usage
coverage-collect.sh	Collect and merge coverage reports

Configuration

Edit config.yaml (copy from config.yaml.example). Key sections:

Timing Thresholds

yaml

active_threshold: 120    # seconds — Codex considered "working"
idle_threshold: 360      # seconds — Codex considered "idle", triggers nudge
cooldown: 120            # minimum seconds between sends to same project

Safety Limits

yaml

max_daily_sends_total: 200   # global daily send cap
max_daily_sends: 50          # per-project daily cap
max_consecutive_failures: 5  # pause project after N failures
loop_detection_threshold: 3  # detect repeated output loops

Multi-Project Scheduler

yaml

scheduler:
  strategy: "round-robin"    # or "priority"
  max_sends_per_tick: 1
  inter_project_delay: 5     # seconds between project sends

Project Directories

yaml

project_dirs:
  - "~/project-alpha"
  - "~/project-beta"

Gemini Frontend Routing

yaml

gemini:
  default_window: "gemini-h5"        # Default tmux window for frontend tasks
  project_windows:
    youxin: "gemini-youxin"          # Per-project Gemini window overrides

Frontend task detection keywords: 页面, 组件, 样式, UI, 前端, H5, 小程序, 界面, frontend, component, style, page, layout

Discord Channel Routing

yaml

discord_channels:
  my-project:
    channel_id: "123456789"
    tmux_window: "my-project"
    project_dir: "/path/to/project"

Telegram Notifications

yaml

telegram:
  bot_token: "YOUR_BOT_TOKEN"
  chat_id: "YOUR_CHAT_ID"
  status_interval: 1800

Usage

Adding a Project

1. Start a Codex CLI session in a named tmux window:

   bash

   tmux new-window -t autopilot -n my-project
   # In the new window, cd to project and run codex
   

2. Add the project path to config.yaml under project_dirs

3. Optionally create projects/my-project/tasks.yaml for task queue:

   yaml

   project:
     name: "My Project"
     dir: "~/my-project"
     enabled: true
     priority: 1
   tasks:
     - id: "feature-x"
       name: "Implement feature X"
       prompt: |
         Implement feature X per the spec in docs/feature-x.md
   

Manual Operations

bash

# Check status of all projects
./scripts/monitor-all.sh

# Manually nudge a specific project
./scripts/auto-nudge.sh my-project

# Send a command to a tmux window
./scripts/tmux-send.sh my-project "codex exec 'fix the tests'"

# Enqueue a backend task (routes to Codex)
./scripts/task-queue.sh add my-project "Refactor auth module"

# Enqueue a frontend task (routes to Gemini)
./scripts/task-queue.sh add my-project "重构登录页面组件" normal --type frontend

# Run the watchdog once (for testing)
./scripts/watchdog.sh

Python Autopilot (Alternative)

autopilot.py provides a Python-based alternative with richer state management:

bash

python3 autopilot.py --once        # single pass
python3 autopilot.py --daemon      # continuous loop
