codex-rescue

A skill that sends an implementation, debugging, or investigation task to Codex and then reviews what Codex changed.

In plain words
What is it for?
It is for delegating coding work to Codex, checking the resulting changes, and following the skill's staged execution rules.
Why use it?
It provides a structured handoff and a second check of the result, while preserving the user's original task wording.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

codex-rescue scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 385 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Codex Task Delegation + Double-Check

You are a translator + executor + double-checker. The user is handing off an implementation task. Your job is to parse their messy input, wrap the verbatim task text in standard prompt scaffolding, let Codex do the work in the background, then review what changed. The scaffolding gives the delegation official-grade structure (scope guards, a verification loop) without ever rewriting the user's words.

The scaffolding is adaptive: rescue's task type is variable (implement / debug / investigate), so you pick the prompt blocks that fit the run instead of forcing one fixed template. You add blocks around the user's text — you never rephrase it — and they approve the result at Phase 1.5.

Critical: do NOT explore the repo before Codex runs. The point of delegating is that Codex builds the context. Exploring first biases your double-check and wastes turns.

Execution Contract

This contract overrides default exploration habits. Read it before Phase 1.

Phase Allowed Forbidden
1 ANALYZE test -f/-s/-d, git status --porcelain (file names only, not contents), echo, printf cat, head, tail, git diff, git log -p, git show, git blame, Read, Grep, Glob
2 INVOKE Bash for companion launch via stdin pipe (no positional!) All source reads
3 WAIT status --wait loop (≤6 iterations, ≤24 min) All source reads, manual polling, ps/kill
4 DOUBLE-CHECK git diff the changed files; Read ONLY files Codex touched or cited Reading whole files "for context"; reading uncited files
5 REPORT + SAVE Write report file n/a

Unknown flags are silently joined into the task prompt by the companion (readTaskPrompt :613-619). Phase 1 whitelist is the only safety net.


Phase 1: Analyze

You are a translator. Use LM intelligence, not regex tables.

Whitelist for this skill:

  • --write (bool; default ON for implementation, OFF for read-only investigation) — companion flag, included in the Phase 2 invocation.
  • --model <slug>, --effort <level>skill-level flags, route through scripts/apply-codex-config.py (see Apply block below) and never reach the companion. The alias spark auto-expands to gpt-5.3-codex-spark. Every other value is written as given — the script judges neither model nor effort, because Codex owns those lists and settles them at run time. That makes Phase 1 the only gate: if a value looks like an obvious typo, AskUserQuestion rather than letting it propagate, since config.toml is global and nothing downstream will second-guess it.
  • --resume-last / --resume / --fresh — mutually exclusive companion flags. Passing resume + fresh triggers Choose either --resume/--resume-last or --fresh. (:750). If ANALYZE produces a conflict, AskUserQuestion; never forward both.
  • --no-preview (bool) — skip Phase 1.5 draft review. For power users who trust the translation and want to skip the approval gate.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

codex-rescue is a skill published in the GitHub repository LeeJuOh/claude-code-zero (51 stars, last pushed 2d ago), licensed MIT. It adds 50 tokens to every session and 4,332 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
