Codex Review

Run Codex's built-in code review as a closeout check. This is code review (codex review), not Guardian auto_review approval routing.

Use when:

• user asks for Codex review / autoreview / second-model review
• after non-trivial code edits, before final/commit/ship
• reviewing a local branch or PR branch after fixes

Contract

• Treat review output as advisory. Never blindly apply it.
• Verify every finding by reading the real code path and adjacent files.
• Read dependency docs/source/types when the finding depends on external behavior.
• Reject unrealistic edge cases, speculative risks, broad rewrites, and fixes that over-complicate the codebase.
• Prefer small fixes at the right ownership boundary; no refactor unless it clearly improves the bug class.
• Keep going until Codex review returns no accepted/actionable findings.
• If a review-triggered fix changes code, rerun focused tests and rerun Codex review.
• Never switch or override the review model. If the review hits model capacity, retry the same command a few times with the same model. The helper runs nested review in yolo/full-access mode by default; use --no-yolo only when intentionally testing sandbox behavior.
• Stop as soon as the review command/helper exits 0 with no accepted/actionable findings. Do not run an extra direct codex review just to get a nicer "clean" line, a second opinion, or clearer closeout wording.
• Treat the helper's successful exit plus absence of actionable findings as the clean review result, even if the underlying Codex CLI output is terse.
• If rejecting a finding as intentional/not worth fixing, add a brief inline code comment only when it explains a real invariant or ownership decision that future reviewers should know.
• Do not push just to review. Push only when the user requested push/ship/PR update.

Pick Target

Dirty local work:

codex review --uncommitted

Use this only when the patch is actually unstaged/staged/untracked in the current checkout. For committed, pushed, or PR work, point Codex at the commit or branch diff instead; do not force --mode local / --uncommitted just because the helper docs mention dirty work first. A clean --uncommitted review only proves there is no local patch.

Branch/PR work:

git fetch origin
codex review --base origin/main

Do not pass an inline prompt with --base; current CLI rejects --base + [PROMPT] even though help text is ambiguous. If custom instructions are needed, run the plain base review first, then do a local/manual follow-up pass.

If an open PR exists, use its actual base:

base=$(gh pr view --json baseRefName --jq .baseRefName)
codex review --base "origin/$base"

Committed single change:

codex review --commit HEAD

or with the helper:

/Users/steipete/Projects/agent-scripts/skills/codex-review/scripts/codex-review --mode commit --commit HEAD

Use commit review for already-landed or already-pushed work on main. Reviewing clean main against origin/main is usually an empty diff after push. For a small stack, review each commit explicitly or review the branch before merging with --base.

Parallel Closeout

Format first if formatting can change line locations. Then it is OK to run tests and review in parallel:

scripts/codex-review --parallel-tests "<focused test command>"

Tradeoff: tests may force code changes that stale the review. If tests or review lead to code edits, rerun the affected tests and rerun review until no accepted/actionable findings remain. Once that rerun exits cleanly, stop; do not spend another long review cycle on redundant confirmation.

Context Efficiency

Codex review is usually noisy. Default to a subagent filter when subagents are available. Ask it to run the review and return only:

• actionable findings it accepts
• findings it rejects, with one-line reason
• exact files/tests to rerun

Run inline only for tiny changes or when subagents are unavailable.

Helper

Bundled helper:

~/.codex/skills/codex-review/scripts/codex-review --help

If installed from agent-scripts, path is:

/Users/steipete/Projects/agent-scripts/skills/codex-review/scripts/codex-review --help

The helper:

• chooses dirty --uncommitted first
• otherwise uses current PR base if gh pr view works
• otherwise uses origin/main for non-main branches
• use --mode commit --commit <ref> for already-committed work, especially clean main after landing
• should be left in --mode auto or forced to --mode branch for PR/branch work; do not force --mode local after committing
• writes only to stdout unless --output or CODEX_REVIEW_OUTPUT is set
• supports --dry-run, --parallel-tests, and commit refs
• runs nested review with --dangerously-bypass-approvals-and-sandbox by default
• keeps accepting --full-access; use --no-yolo or CODEX_REVIEW_YOLO=0 to opt out
• prints codex-review clean: no accepted/actionable findings reported when the selected review command exits 0

Final Report

Include:

• review command used
• tests/proof run
• findings accepted/rejected, briefly why
• the clean review result from the final helper/review run, or why a remaining finding was consciously rejected

Do not run another Codex review solely to improve the final report wording. If the final helper run exited 0 and produced no accepted/actionable findings, report that exact run as clean.
