SKILL.md
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
taskonce 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, orcancelfromcodex:codex-rescue. - Use
taskfor every rescue request, including diagnosis, planning, research, and explicit fix requests. - You may use the
gpt-5-4-promptingskill to rewrite the user's request into a tighter Codex prompt before the singletaskcall. - 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
--effortunset unless the user explicitly requests a specific effort. - Leave model unset by default. Add
--modelonly when the user explicitly asks for one. - Map
sparkto--model gpt-5.3-codex-spark. - Default to a write-capable Codex run by adding
--writeunless the user explicitly asks for read-only behavior or only wants review, diagnosis, or research without edits.
Command selection:
- Use exactly one
taskinvocation per rescue handoff. - If the forwarded request includes
--backgroundor--wait, treat that as Claude-side execution control only. Strip it before callingtask, and do not treat it as part of the natural-language task text. - If the forwarded request includes
--model, normalizesparktogpt-5.3-codex-sparkand pass it through totask. - If the forwarded request includes
--effort, pass it through totask. - 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 usetask --resume-last, even if the request text is ambiguous.--fresh: always use a freshtaskrun, even if the request sounds like a follow-up.--effort: accepted values arenone,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-rescueunless 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
taskcommand exactly as-is. - If the Bash call fails or Codex cannot be invoked, return nothing.

gpt-5-4-prompting
Internal guidance for composing Codex and GPT-5.4 prompts for coding, review, diagnosis, and research tasks inside the Codex Claude Code plugin
codex-result-handling
Internal guidance for presenting Codex helper output back to the user
openai-docs
Use when the user asks how to build with OpenAI products or APIs and needs up-to-date official documentation with citations, help choosing the latest model for a use case, or explicit GPT-5.4 upgrade and prompt-upgrade guidance; prioritize OpenAI docs MCP tools, use bundled references only as helper context, and restrict any fallback browsing to official OpenAI domains.
plugin-creator
Create and scaffold plugin directories for Codex with a required `.codex-plugin/plugin.json`, optional plugin folders/files, and baseline placeholders you can edit before publishing or testing. Use when Codex needs to create a new local plugin, add optional plugin structure, or generate or update repo-root `.agents/plugins/marketplace.json` entries for plugin ordering and availability metadata.
skill-installer
Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos).
skill-creator
Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations.
