codex-review — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited codex-review (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
/codex-review — reviews staged changes (git diff --staged) /codex-review HEAD~N — reviews last N commits /codex-review [file ...] — reviews specific files
Get an independent GPT code review via Codex CLI. Claude evaluates each GPT finding (agree, correct, or dismiss), adds severity levels, and presents a structured actionable review.
git diff --staged. If nothing staged, run git diff HEAD~1 for the last commit.HEAD~N pattern: run git diff HEAD~N1. graph_continue (mandatory first call)
2. graph_impact(changed_files=[...list of modified files...])
→ shows which parts of the codebase depend on what's being changed
3. graph_read each modified file
→ gives Claude full current file content before sending anything to GPT
4. graph_action_summary
→ surfaces locked architectural decisions; flag if review would violate anyFor diffs up to ~200 lines, send in one call. For larger diffs, send one file at a time.
codex exec "Independent code review. Context: <TASK_OR_DESCRIPTION>. Code/diff to review: <CODE_OR_DIFF>. Review for: (1) bugs and logic errors, (2) security vulnerabilities (injection, auth bypass, data exposure), (3) performance issues, (4) missing error handling, (5) readability and naming. Format each finding as: [BUG|SECURITY|PERF|STYLE|MISSING]: file:line — issue — suggested fix. End with VERDICT: approved | approved-with-notes | needs_revision"For each GPT finding, Claude:
Verdict: approved | approved-with-notes | needs_revision
CRITICAL / HIGH — Must Fix: [list with file:line and fix]
MED — Should Fix: [list]
LOW / Style — Consider: [list]
Blast Radius: [if tessera active — what this change affects downstream]
Decision Conflicts: [if any locked decisions conflict with this change — flag before proceeding]
Ask: fix critical/high issues now?
If reviewing staged changes before a commit and tessera MCP is active: run tessera-verify as a final gate to confirm all plan checklist items are satisfied.
