Model Worker Routing

Use this skill only for an explicit opt-in route. Do not infer delegation from task size, cost, token usage, or coding difficulty.

Trigger

Trigger only when the current user request explicitly contains Ox Alpha, including these forms:

• 本任務用 Ox Alpha
• 本任務交給 Ox Alpha
• 這個任務用 Ox Alpha
• 這次用 Ox Alpha
• 請用 Ox Alpha 執行本任務
• 用 Ox Alpha 做這個任務
• 本任務用 Ox Alpha 代替 Sol
• Use Ox Alpha for this task
• Run this task with Ox Alpha
• Delegate this task to Ox Alpha

Do not trigger for generic requests such as「修改這個 Repo」「跑 tests」「省 token」or「用便宜模型」.

Workflow

1. Preserve the user's task text, but send only the task and constraints to the worker. Do not send the full conversation, parent reasoning, or a pre-scanned repository dump.

2. Determine the current workspace from the active thread/cwd using pwd and, when applicable, git rev-parse --show-toplevel. If the workspace cannot be determined reliably, stop with a concise workspace-needed message; do not guess.

3. Validate that the workspace exists and is not a credential, system, home-root, or Codex-settings directory. A read-only task may inspect the current workspace; a write or write-test task must use an isolated/disposable workspace when the current workspace is dirty. Never overwrite uncommitted changes.

4. Choose the lowest deterministic permission mode:

   • read for analyse, inspect, scan, review, explain, or risk-finding requests.
   • write for modify, fix, update, refactor, or add-file requests without a test requirement.
   • write-test when the request also asks to run, verify, or pass tests. If uncertain, choose the lower mode.

5. Invoke the existing single source of truth exactly once:

   python3 "${CODEX_HOME:-$HOME/.codex}/model-routing-mvp/route_task.py" \
     --message "<original task containing the explicit Ox Alpha route>" \
     --workspace "<validated workspace>" \
     --workspace-root "<safe parent root>" \
     --permission-mode "<read|write|write-test>"
