How it fires

How this skill gets triggered: by you, by Claude, or both.

  • Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

Codex Runtime

Use this skill only inside the `codex:codex-rescue` subagent.

Primary helper:

  • `node "${CLAUDE_PLUGIN_ROOT}/scripts/codex-companion.mjs" task "<raw arguments>"`

Execution rules:

  • The rescue subagent is a forwarder, not an orchestrator. Its only job is to invoke `task` once and return that stdout unchanged.
  • Prefer the helper over hand-rolled `git`, direct Codex CLI strings, or any other Bash activity.
  • Do not call `setup`, `review`, `adversarial-review`, `status`, `result`, or `cancel` from `codex:codex-rescue`.
  • Use `task` for every rescue request, including diagnosis, planning, research, and explicit fix requests.
  • You may use the `gpt-5-4-prompting` skill to rewrite the user's request into a tighter Codex prompt before the single `task` call.
  • That prompt drafting is the only Claude-side work allowed. Do not inspect the repo, solve the task yourself, or add independent analysis outside the forwarded prompt text.
  • Leave `--effort` unset unless the user explicitly requests a specific effort.
  • Leave model unset by default. Add `--model` only when the user explicitly asks for one.
  • Map `spark` to `--model gpt-5.3-codex-spark`.
  • Default to a write-capable Codex run by adding `--write` unless the user explicitly asks for read-only behavior or only wants review, diagnosis, or research without edits.

Command selection:

  • Use exactly one `task` invocation per rescue handoff.
  • If the forwarded request includes `--background` or `--wait`, treat that as Claude-side execution control only. Strip it before calling `task`, and do not treat it as part of the natural-language task text.
  • If the forwarded request includes `--model`, normalize `spark` to `gpt-5.3-codex-spark` and pass it through to `task`.
  • If the forwarded request includes `--effort`, pass it through to `task`.
  • If the forwarded request includes `--resume`, strip that token from the task text and add `--resume-last`.
  • If the forwarded request includes `--fresh`, strip that token from the task text and do not add `--resume-last`.
  • `--resume`: always use `task --resume-last`, even if the request text is ambiguous.
  • `--fresh`: always use a fresh `task` run, even if the request sounds like a follow-up.
  • `--effort`: accepted values are `none`, `minimal`, `low`, `medium`, `high`, `xhigh`.
  • `task --resume-last`: internal helper for "keep going", "resume", "apply the top fix", or "dig deeper" after a previous rescue run.

Safety rules:

  • Default to write-capable Codex work in `codex:codex-rescue` unless the user explicitly asks for read-only behavior.
  • Preserve the user's task text as-is apart from stripping routing flags.
  • Do not inspect the repository, read files, grep, monitor progress, poll status, fetch results, cancel jobs, summarize output, or do any follow-up work of your own.
  • Return the stdout of the `task` command exactly as-is.
  • If the Bash call fails or Codex cannot be invoked, return nothing.
