Add magic-cc-codex-worker

[wenqingyu]

Adds magic-cc-codex-worker, a Claude Code plugin that turns OpenAI Codex into a pool of parallel agent workers running in isolated git worktrees.

What it does

• Spawn N Codex agents in parallel, each in its own git worktree — no collisions on the main tree.
• Resumable sessions (continue a worker across Claude Code sessions via Codex codex-reply on stored thread_id).
• Dual-model PR review: mount a PR in a detached worktree, run a GPT reviewer alongside your Claude review.
• Role-tuned specialization (implementer / reviewer / planner / generic) with per-role sandbox + timeout.
• Auto-detected Magic Flow integration (Linear issue enrichment, branch conventions, workers.json mirror) — opt-out by absence.

Stats

• 62 unit tests, strict TypeScript, CI on Node 20/22
• Self-contained single-file MCP server (no npm install needed at install time)
• 9 slash commands + 3 subagents + 9 custom MCP tools
• License: PolyForm Noncommercial 1.0.0 (free for independent devs / research / nonprofits; commercial use requires separate license)

Install via:

/plugin marketplace add wenqingyu/magic-cc-codex-worker
/plugin install magic-codex@magic-codex

Contribution checklist:

• Real use case (parallel agent orchestration; dual-model review)
• Does not duplicate an existing entry — nearest neighbor is maestro-orchestrate but this is Codex-specific, not Claude-subagent-based
• Plugin is installed + tested (62 unit tests + live end-to-end verified)
