codex-fix

codex-fix is a skill for Claude Code, Codex from subinium/vibesubin. It costs 154 tokens per session (4,142 once invoked), scanned A, original, MIT.

A post-edit review workflow that asks a second model to inspect code changes, then passes its findings to another workflow for deciding what to fix, verifying the fixes, and recording them in commits.

In plain words
What is it for?
Reviewing a completed set of code changes, sorting review findings, tracing them to changes with git history, checking fixes, and producing a resolution report. It is intended for Claude Code users with the Codex plugin installed.
Why use it?
It removes the need to copy review findings between separate tools after a batch of edits. It also helps distinguish real issues from false alarms, duplicates, and items to defer.

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-fix 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 5d 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 — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.

codex-fix

A thin, deliberately host-specific wrapper for one workflow: "I've finished a batch of edits — run Codex for a second-model review, feed the findings back, let Claude resolve them with verification."

This wrapper owns only the Codex-specific glue: the host check, the templated /codex:rescue prompt, the output collection, and the hand-off. Everything after the hand-off — parsing and normalizing findings, triaging real / false-positive / defer / duplicate, mapping each finding to a commit via git blame, planning a dependency tree, executing leaves-up, verifying each fix with the applicable checks, committing with a back-reference to the review item, and producing the resolution report — belongs to refactor-verify's review-driven fix mode. This skill does not duplicate any of it.

If you are not on Claude Code with the Codex plugin installed, you do not need this skill. refactor-verify accepts pasted review findings from any source directly — this wrapper just automates the invocation step for operators who run the Codex loop often enough that the copy-paste was adding friction.

State assumptions — before acting

Before starting the procedure, write an explicit Assumptions block. Don't pick silently between interpretations; surface the choice. If any assumption is wrong or ambiguous, pause and ask — do not proceed on a guess.

Required block:

Assumptions:
- Host:              <Claude Code + Codex plugin (primary path) | any other (graceful one-line fallback, exit)>
- Review branch:     <current branch | specified — merge-base with main is the diff scope>
- Working tree:      <clean (proceed) | dirty (warn operator before handing mixed state to Codex)>
- Base reference:    <main (default) | explicit base when current branch has no merge-base with main>

Typical items for this skill:

  • The branch under review (default: current branch vs its merge-base with main)
  • Working tree state (clean required for a clean review; dirty triggers a warning before invocation)
  • Codex plugin availability (host check in Step 1 — this Assumptions block is Step 0, the host check is Step 1)

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.
