Codex Runtime

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

Primary helper:

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.
