description	Use if reviewing a PR/diff, requesting review on your branch, triaging feedback, or delegating.

run-review

Single entry point for every code-review intent. The skill does not silently pick a workflow — it routes by mode. On activation, pick the mode explicitly (or ask), then execute the per-mode procedure.

The four modes cover the only four review intents that exist in practice:

Mode	Intent in one sentence	What used to live here
A — Do a review	Review someone's PR, branch, or diff for merge readiness.	the old review-pr / do-review skill
B — Ask for review	Hand off your own branch as a reviewable PR (self-review body, optional gh pr create).	the old review-self / ask-review skill
C — Evaluate received feedback	Triage human + bot comments, markdown audit docs, or earlier session feedback into accept / pushback / clarify / defer / dismiss.	the old review-feedback / evaluate-code-review skill
D — Delegate to codex	Run codex review (or codex exec review) against the same target; surface findings back inside Claude.	new — wraps the codex CLI's native review command

This skill replaces those three older skills and folds codex review in as a peer mode, so the user never has to guess which review skill to pick.

When to use this skill

Trigger phrases (any one is sufficient):

• "review PR #N", "review github.com/owner/repo/pull/N", "walk this diff", "is this safe to merge?" → Mode A
• "open a PR for this", "write me a self-review", "this is ready for review", "hand this off" → Mode B
• "address the review comments on PR #N", "the bots reviewed my PR", "go back over the reviewer's notes", "read review.md and give me an action plan" → Mode C
• "run codex review on this", "have codex review the diff", "codex review --uncommitted", "second opinion from codex" → Mode D

Do not use this skill for:

• per-branch codex review fix loops over a list of branches → multi-branch codex review orchestration
• repo-cleanup of dirty trees across multiple worktrees with no review handoff yet → run-repo-cleanup
• chasing a runtime bug with no diff to judge → use the repository's debugging workflow
• generic codex-CLI orchestration without a review intent → parallel codex exec orchestration or parallel codex exec orchestration

Mode selection (load-bearing — do not skip)

On every activation, before any tool call beyond reading state:

1. Read the user's literal phrasing against the trigger table above.
2. Apply the inference rules (next subsection). If a single mode wins with high confidence, state the mode in one line and proceed.
3. If two or more modes are plausible, ASK. Default to asking when in doubt — a wrong mode wastes a lot of subagent compute. Use AskUserQuestion when available; otherwise emit the inline numbered prompt below.

Inference rules

Apply in order; the first matching rule wins. Each rule lists the literal cue and the mode it routes to.

#	Cue in the user's request	Mode
1	The phrase codex review, codex exec review, have codex review, or any direct mention of running the codex CLI to review code.	D
2	Words open a PR / hand off / ready for review / self-review / write the review body / ship this branch applied to the user's own work, AND no third-party review comments are named.	B
3	Words evaluate / triage / address / respond to / answer / sort out applied to feedback already in hand — PR comments, named bots (Copilot, CodeRabbit, Greptile, Devin, Bito, Codex), or a markdown file like review.md / audit.md / feedback.md.	C
4	A PR number, URL, branch comparison, or gh pr view target named by the user with words review / look at / merge-readiness / walk this diff / sanity-check, and no mention of codex CLI.	A
5	None of the above OR multiple rules fire at the same confidence.	ASK

When confidence is borderline (e.g., the user names a PR but also says "have codex take a look") — that is rule 1 first; codex CLI wins. When the user says "open a PR and have codex review it" — that is two modes in sequence: B (open the PR) then D (codex review against the new branch). Run them in order and say so out loud before starting.

How to ask when ambiguous

If the user's phrasing does not uniquely select a mode, surface the four choices verbatim and stop. Use the AskUserQuestion tool when available with one question and these four options. Otherwise emit this block in chat and wait:

I can run this in one of four review modes. Which do you want?

  A) Do a review — I review your PR / branch / diff for merge readiness.
  B) Ask for review — I clean up your branch and open a PR with a self-review body.
  C) Evaluate received feedback — I triage comments / bot output / a review doc into an action plan.
  D) Delegate to codex — I run `codex review` against the diff and surface its findings.

Reply with A, B, C, or D (or describe the work in one line).

Never hide a mode to "narrow" the choice. The user must always see all four. Multi-mode requests are fine — they execute in sequence.

Once the mode is locked

State the chosen mode in one line before starting. Do not swap modes mid-workflow without re-asking. If, while executing, you discover the user actually wanted a different mode, stop, name the mismatch, and re-route.

Mode A — Do a review (review someone's PR / branch / diff)

Trigger phrases

"review PR #123", "review github.com/owner/repo/pull/N", "is this safe to merge?", "walk this diff", "review main...feature-branch", "review my working tree", "the PR already has CodeRabbit comments — what's left?", "this PR has 40 files; tell me what to look at first".

Required inputs

Exactly one comparison target. Name it in one line before reading code:

• owner/repo#N for GitHub PR mode
• <base>...<head> for branch diff mode (e.g. origin/main...HEAD)
• HEAD + staged + unstaged for working-tree mode

If the target cannot be named in one line, stop and ask. Do not invent a diff target.

Procedure (8 phases, owned by Mode A)

1. Triage the request — full vs targeted, draft vs ready, security-only vs general. Inline; no reference.
2. Gather context before code — references/mode-a-do-review/workflow/review-workflow.md (Phase 1). Tooling: scripts/parse-pr.sh (see scripts/parse-pr.md), references/mode-a-do-review/workflow/gh-cli-reference.md.
3. Scope and cluster files — references/mode-a-do-review/analysis/file-clustering.md. Tooling: scripts/cluster-files.sh (see scripts/cluster-files.md).
4. Read existing review state — references/mode-a-do-review/workflow/comment-correlation.md, references/mode-a-do-review/workflow/automation.md. Treat Copilot, CodeRabbit, Greptile, Devin, Bito, CodeQL, Snyk, etc. as prior review — dedupe, do not repeat.
5. Validate goals — references/mode-a-do-review/workflow/review-workflow.md (Phase 4). A PR that passes every quality check but misses its stated outcome is a failed PR.
6. Review by cluster — apply dimensions in order: security → correctness → data integrity → API contract → performance → tests → maintainability. Detail: references/mode-a-do-review/dimensions/review-dimensions.md, references/mode-a-do-review/dimensions/security-review.md, references/mode-a-do-review/dimensions/performance-review.md, references/mode-a-do-review/dimensions/bug-patterns.md, references/mode-a-do-review/dimensions/language-specific.md. Diff reading help: references/mode-a-do-review/analysis/diff-analysis.md.
7. Cross-cutting sweep — references/mode-a-do-review/analysis/cross-cutting.md. Large PR strategy: references/mode-a-do-review/analysis/large-pr-strategy.md.
8. Calibrate, synthesize, output — references/mode-a-do-review/output/output-templates.md, references/mode-a-do-review/output/communication.md, references/mode-a-do-review/output/anti-patterns.md. Severity calibration: references/mode-a-do-review/dimensions/severity-guide.md.

Subagent dispatch — when to fan out

Mode A is single-agent by default. Dispatch subagents only when ALL of:

• changed files ≥ 15 OR changed lines > 500
• cluster map (Phase 3) shows ≥ 2 high-risk clusters that can be reviewed independently
• the user has not asked for a quick / shallow review

If those conditions hold, dispatch one subagent per cluster. Each subagent receives: cluster file list, base/head refs, the dimensions checklist at references/mode-a-do-review/dimensions/review-dimensions.md, and the actionability gate from Phase 6. Subagents return findings only — the parent agent owns calibration, dedup, and verdict.

For PR < 100 changed lines, do not dispatch — single-agent inline is faster.

Output shape

Markdown review in chat by default. The body includes: verdict (✅ Approve / 💬 Comment / 🔄 Request Changes), findings grouped by severity (🔴 blocker, 🟡 important, 🟢 suggestion, 💡 question), at least one specific positive observation (🎯), summary of existing review state (or "unavailable in local diff mode"), deep-reviewed vs skimmed clusters, CI/check state. Each finding contains: severity, title, exact file:line, observed behavior, impact, and suggested fix or question.

GitHub mutation (posting a formal review or inline comments) happens only when the user explicitly says submit / post / publish / comment. Default is markdown only.

Hand-off contract

After Mode A: the user has a markdown review (or, on explicit request, a posted GitHub review). No commits made, no PR opened, no fixes applied. If the user asks "now go fix the blockers," that is a new task — not part of Mode A.

Per-item programmatic mode

When this skill is called from multi-branch codex review orchestration (or its the retired the now-retired codex review skill shim) with a single candidate finding plus a branch diff, output JSON only per the contract:

{
  "decision": "accepted|rejected|ambiguous",
  "severity": "blocker|important|suggestion|question",
  "evidence": ["file:line"],
  "rationale": "Why the item does or does not survive review.",
  "intended_fix_shape": "Only for accepted items."
}

Mode B — Ask for review (open a PR with a self-review body)

Trigger phrases

"open a PR for this", "hand this off for review", "this is ready for review", "write me a self-review", "clean up my commits and open a PR", "give me a review doc — no PR, just the markdown", "summarize this branch for the reviewer".

Required inputs

• The user's current branch (must not be main / master / default).
• A clean or tidy-able working tree.
• Owner/repo for gh (read from git remote -v; pass --repo explicitly every time).
• The user's intent: PR handoff (default) vs markdown review doc (explicit request only).

Two output modes

Sub-mode	Trigger phrase	Produced artifact
PR handoff (default)	silence on format, "open a PR", "ready for review", "hand this off"	clean branch pushed, gh pr create executed, self-review body posted
Markdown review doc	"just the text", "no PR", "give me a review doc", "write the review as markdown"	markdown file or inline output; no git writes, no PR

If ambiguous, ask once before doing anything. Default is not a license to skip the ask when intent is genuinely unclear.

Procedure

1. Classify the sub-mode — state PR handoff or markdown-doc out loud before proceeding.
2. Inspect current state — git status --short, git branch --show-current, git log --oneline origin/main..HEAD, git remote -v, gh pr list --head <branch>. Capture: dirty? on default branch? unpushed? PR already exists?
3. Handle dirty tree first — commit before opening the PR, never after. Diff-walk commits, group by domain, one conventional commit per concern. No git commit -am, no blind git add -A. If on default branch, create a branch first (git switch -c <type>/<scope>-<slug>). Detail: references/mode-b-ask-review/handoff-mechanics.md. RED-baseline excuses to refuse: references/mode-b-ask-review/rationalizations.md.
4. Classify the diff's domain — match the changed paths against one of seven domains. Read the one that matches before drafting:
   • server / API / SQL / auth / infra → references/mode-b-ask-review/domains/backend.md
   • client-side TS / JS / React / Vue / Svelte (outside server/) → references/mode-b-ask-review/domains/frontend-ts-js.md
   • @modelcontextprotocol/sdk imports, Zod tool schemas, SKILL.md authoring → references/mode-b-ask-review/domains/mcp-server.md
   • CSS / Tailwind / design tokens / a11y / layout → references/mode-b-ask-review/domains/ui-engineering.md
   • bin/, scripts/*.sh, argparse / commander, flag parsing, exit codes → references/mode-b-ask-review/domains/cli-tool.md
   • prose *.md under content/, posts/, docs/, README bodies → references/mode-b-ask-review/domains/content-markdown.md
   • anything else or a clear mix that does not split cleanly → references/mode-b-ask-review/domains/generic.md
5. Draft the body — follow references/mode-b-ask-review/review-text-template.md. Under 50,000 chars; explain every change; surface ≥ 2 weaknesses the author already knows about; ask ≥ 1 explicit reviewer question.
6. Ship it — gh pr create --repo <owner>/<repo> --base <target> --head <current> --title "<type>(<scope>): <subject>" --body-file /tmp/pr-body.md, then verify with gh pr view <N> --repo <owner>/<repo> --json url,baseRefName,headRefName. URL must point to the intended repo; base must be the intended target.

Subagent dispatch — when to fan out

Dispatch when the diff touches 2+ domains AND each domain has ≥ 5% of the changed lines. One subagent per domain cluster. Each subagent receives: BASE_SHA + HEAD_SHA, paths restricted to its cluster, the matching domain reference, and the prompt template at references/mode-b-ask-review/subagent-dispatch.md. Each returns per-domain change summary, weaknesses, 1-3 reviewer questions.

Combine outputs into one coherent body — one section per domain under an ## Areas heading, plus an overall summary. Single-domain diffs skip this step.

Output shape

PR handoff: PR URL plus the verification block from gh pr view. Markdown mode: the body inline or written to the user-named path. Body must include weaknesses (≥ 2) and reviewer questions (≥ 1).

Hand-off contract

After Mode B: branch is pushed, PR is open (PR mode) or markdown is delivered (doc mode). git status --short is empty on the author's branch. The reviewer now owns the next move. Do not start running fixes from your own self-review weaknesses — those are signals to the reviewer.

Mode C — Evaluate received feedback

Trigger phrases

"address the review comments on PR #42", "what do the bots say on my PR", "Copilot and CodeRabbit disagree — sort it out", "merge what the three reviewers said", "go back and check the reviewer's notes from earlier", "read review.md and give me an action plan", "the reviewer's notes are in audit.md", "reply in the PR threads with my answers".

Required inputs

Feedback in one of three shapes:

Input mode	Detection	Source
PR mode	user names a PR (number, URL) and review comments	scripts/parse-pr-comments.sh --repo <owner/name> --pr <N> --out <dir> (see scripts/parse-pr-comments.md)
Session-audit mode	user references review notes earlier in this conversation	prior messages
Markdown-doc mode	user names a file like review.md, audit.md, feedback.md	the file on disk

If genuinely ambiguous: scan prior messages, then gh pr view on the current branch, then look for review*.md / audit*.md / feedback*.md in the working dir. Report what was found before proceeding.

Procedure

1. Identify the input mode and surface the feedback — extract every item as a flat list with verbatim text, source, location, code-range metadata, severity hint. For PR mode, run scripts/parse-pr-comments.sh to fetch all three GitHub feedback channels (top-level reviews, inline review comments, PR-discussion comments).

2. Reconstruct ground truth — what change set should the reviewer have been looking at? Fallback chain at references/mode-c-evaluate-feedback/understand-changes.md: branch commits → tool-trail (Edit/Write calls in the session) → bash trail → uncertain. Stop and name uncertainty rather than guessing.

3. Dispatch an Explore subagent — ALWAYS. Even single-item reviews. Self-contained prompt — no "as we discussed earlier", no session references. Template: references/mode-c-evaluate-feedback/subagent-dispatch.md. Subagent returns per-item {verdict, evidence: file:line + reasoning, severity}.

4. Consolidate multi-source feedback — if 2+ reviewers, line-range cluster (same file + overlapping range, ±5 lines) and merge duplicates. Surface conflicts explicitly — never silently pick one. Detail: references/mode-c-evaluate-feedback/multi-agent-consolidation.md. Tooling: scripts/cluster-feedback.py --input normalized.jsonl --output clusters.json (see scripts/cluster-feedback.md).

5. Evaluate each item — combine the subagent's verdict with parent verification. Six-check lens at references/mode-c-evaluate-feedback/verification.md. Each item gets one verdict:

   Verdict	Meaning
   ACCEPT	feedback is correct and worth acting on
   PUSHBACK	feedback is wrong; respond with technical reasoning
   CLARIFY	feedback is unclear or evidence is missing; ask
   DEFER	correct but out of scope for this PR; log as follow-up
   DISMISS	noise, unambiguously wrong, or reviewer lacks context

6. Produce the action plan — format depends on input mode. See references/mode-c-evaluate-feedback/action-plan-output.md. PR mode: reply in threads via gh api repos/{o}/{r}/pulls/{pr}/comments/{id}/replies. Session-audit mode: markdown action plan inline. Markdown-doc mode: write <source>-action-plan.md next to the source.

7. Implement (only if authorized) — order: blocking → simple → complex. One item at a time, test each before the next. After each item, reply in the thread (PR mode) or update the plan (markdown mode) with Fixed. <what changed>. — no gratitude, no praise, no apology.

Voice discipline (load-bearing)

No performative agreement. No gratitude. No praise. No apology. No agreement-before-verification. The diff is the acknowledgment. Phrase-level rules at references/mode-c-evaluate-feedback/voice.md. Pressure-scenario excuses at references/mode-c-evaluate-feedback/rationalizations.md. GH thread mechanics at references/mode-c-evaluate-feedback/gh-review-workflow.md.

Subagent dispatch — when to fan out

The single Explore subagent in Step 3 is mandatory even for one-item reviews — bias control, not parallelism. Fan out further when ≥ 30 distinct feedback items survive deduplication. Group items by file or by cluster (Step 4) and dispatch one subagent per cluster with: ground-truth diff, the cluster's items, and references/mode-c-evaluate-feedback/verification.md. Parent agent reconciles conflicting subagent verdicts and surfaces irreconcilable ones in the final plan.

Output shape

Decision register: per item, {id, channel, source, source_type, file:line, commit_id, verbatim_text, verdict, evidence, planned_action, implementation_status}. Action plan grouped by verdict. PR-thread reply log if PR mode and replies were authorized.

Hand-off contract

After Mode C: every received item has a verdict. If implementation was authorized, accepted items are fixed in order (blocking → simple → complex), each with a thread reply. If implementation was not authorized, the action plan is the deliverable and the user owns the next step. Never implement without authorization just because the verdict was ACCEPT.

Mode D — Delegate to codex

Trigger phrases

"run codex review on this", "codex review --uncommitted", "have codex review the diff", "codex review against main", "have codex sanity-check this commit", "second opinion from codex", "non-interactive codex review".

Required inputs

• codex binary on PATH (command -v codex succeeds; the skill is built against codex-cli 0.130.0+).
• One review target — see flag table below.
• Optional custom prompt ([PROMPT] positional arg) when the user wants a focused review (security only, perf only, against a spec doc, etc.).

codex review flag surface (from live codex review --help)

The codex root-level review subcommand runs a one-shot code review non-interactively. Confirmed against codex review --help in codex-cli 0.130.0:

Usage: codex review [OPTIONS] [PROMPT]

Arguments:
  [PROMPT]                Custom review instructions. If `-` is used, read from stdin.

Options:
  -c, --config <key=value>   Override a config value (TOML-parsed; dotted paths supported).
                             Examples: -c model="o3", -c 'sandbox_permissions=["disk-full-read-access"]'.
      --uncommitted          Review staged, unstaged, and untracked changes.
      --base <BRANCH>        Review changes against the given base branch.
      --enable <FEATURE>     Enable a feature (repeatable). Equivalent to -c features.<name>=true.
      --commit <SHA>         Review the changes introduced by a commit.
      --disable <FEATURE>    Disable a feature (repeatable). Equivalent to -c features.<name>=false.
      --title <TITLE>        Optional commit title to display in the review summary.
  -h, --help                 Print help.

Target selection — pick exactly one:

User intent	Flag
review the diff against main (or other base)	--base main
review uncommitted work (staged + unstaged + untracked)	--uncommitted
review the changes a single commit introduced	--commit <SHA>
review against the default base inferred from repo state	(no target flag — codex picks)

Auxiliary flags worth exposing to the user:

• --title "<text>" — display in the summary header; useful when reviewing a --commit or --uncommitted change with no PR title.
• --enable <feature> / --disable <feature> — toggle codex features (-c features.<name>=true|false).
• -c key=value — override config. Common: -c model="o3" to pin model, -c model_reasoning_effort="high" to raise effort.
• [PROMPT] — positional. Custom review instructions. - reads from stdin (useful when the user has a long brief).

The root codex review does not accept --json, -o, or --dangerously-bypass-approvals-and-sandbox. If the user needs machine-readable output, structured logs, or a non-interactive sandbox-bypass surface, switch to codex exec review (the broader surface — see "When to use codex exec review" below).

Procedure

1. Pre-flight —

   • command -v codex succeeds.
   • git rev-parse --is-inside-work-tree succeeds in cwd.
   • If --base <BRANCH> is chosen, git rev-parse --verify <BRANCH> succeeds (fetch first if not).
   • If --commit <SHA> is chosen, git rev-parse --verify <SHA> succeeds.
   • codex login status succeeds — OR USE_CODEX_SKIP_CODEX_AUTH=1 is set when bearer-token / managed-companion / proxy auth is in use.
   • If any pre-flight fails, stop and report; do not improvise into codex exec.

2. Pick the target flag — one of --base <BRANCH>, --uncommitted, or --commit <SHA>. State the choice and rationale in one line.

3. Compose the invocation. Default (no custom prompt):

   codex review --base main
   

   With a custom prompt:

   codex review --base main "Review focuses on auth and session handling. Flag any missing input validation, replay vulnerabilities, or token leakage."
   

   With a long brief on stdin:

   cat brief.md | codex review --base main -
   

   With config overrides:

   codex review --base main -c model="o3" -c model_reasoning_effort="high"
   

4. Run it. Run interactively (the operator watches the stream) or capture stdout when the output is long:

   mkdir -p /tmp/codex-review
   codex review --base main "<prompt>" 2>&1 | tee /tmp/codex-review/$(date +%Y%m%dT%H%M%S)-review.md
   

   Capture the output verbatim — codex review prints the findings to stdout. When the review is long (> 200 lines or large repos), always tee to disk so the user can scroll without losing scrollback.

5. Surface the result back to the user. Default surface: paste the codex review findings inside chat under a clear heading. If long, write to disk and report the path. Do not silently drop or summarize codex output — the user asked for codex's opinion, surface it intact.

6. Optional: chain into Mode A or Mode C.

   • If the user asks Claude to validate codex's findings against the diff → switch to Mode A's per-item programmatic mode (one JSON object per item with accepted | rejected | ambiguous).
   • If the user asks Claude to act on codex's findings → switch to Mode C, treating codex output as one more reviewer (source codex, source_type bot).

When to use codex exec review instead

codex exec review accepts the broader exec flag surface and is preferred when:

• the user wants --json JSONL events,
• the user wants -o <file> to write the last message to disk,
• the user wants -m <model> or --dangerously-bypass-approvals-and-sandbox (e.g. inside a CI worker / sandbox already),
• the user wants --ephemeral (no session files persisted),
• a fleet driver (multi-branch codex review orchestration) is the caller — that path always uses codex exec review.

Quick codex exec review invocation (one-shot, machine-readable):

mkdir -p /tmp/codex-review
codex exec review \
  --dangerously-bypass-approvals-and-sandbox \
  --skip-git-repo-check \
  --json \
  -o /tmp/codex-review/last.md \
  --base main \
  "Review the auth subsystem changes for replay and token-leak issues."

For per-branch convergence loops over multiple branches, do not wire that yourself — route to multi-branch codex review orchestration by writing a thin orchestrator that fans out codex exec review --base <ref> calls per branch (the dedicated dispatcher skill was retired).

Subagent dispatch — when to fan out

Mode D is single-agent by default — the codex CLI is itself the worker; Claude orchestrates. Dispatch a subagent only when:

• the user names ≥ 3 review targets (e.g., three commits) that should each get their own codex pass, AND
• the targets are independent (not stacked).

In that case, dispatch one subagent per target with a self-contained prompt: target flag, optional brief, output path. Subagents collect codex output; the parent surfaces the merged result. For ≥ 2 branches with stacked dependencies, do not subagent — route to multi-branch codex review orchestration.

Output shape

Codex's review text, surfaced verbatim (in chat or in /tmp/codex-review/<ts>-review.md). When the user asked Claude to act on the output, the next mode (A or C) owns its own output shape.

Hand-off contract

After Mode D: the user has codex's review (text on stdout or markdown on disk). No git mutation, no PR opened, no fixes applied. Codex review never opens PRs (Mode B does); codex review never auto-applies fixes (the user does, or Mode C orchestrates).

Cross-mode rules

1. Never silently switch modes. If, while running mode X, you realize the user actually wanted mode Y, stop, name the mismatch, and re-route. Do not just start doing Y.
2. Never combine mode bodies in one output. Modes have distinct output shapes; do not produce a "PR body and a review" simultaneously. If two modes are queued, run them in order, produce two outputs.
3. Authorization is per destructive action. gh pr create (Mode B), gh pr review --request-changes (Mode A), gh api .../replies (Mode C posting replies), git push (Mode B), and any codex exec with --dangerously-bypass-approvals-and-sandbox (Mode D) all require explicit user authorization. Authorization for one such action is not authorization for the next.
4. No GitHub mutation in Modes A or D by default. Mode A produces markdown by default; explicit submit/post/publish/comment switches it to GitHub mutation mode. Mode D never mutates GitHub at all.
5. Voice discipline applies in every mode. No gratitude, no praise, no apology, no agreement-before-verification — most load-bearing in Mode C but never wrong anywhere. references/mode-c-evaluate-feedback/voice.md is the canonical phrase reference.
6. multi-branch codex review orchestration owns multi-branch convergence. If the user names ≥ 2 branches and a "review/ship/merge/close out" intent, this skill routes to parallel codex exec orchestration — not Mode D, not Mode A.
7. the now-retired codex review skill is a routing shim. It points at this skill plus parallel codex exec orchestration. Do not restore the old runner; the canonical owners are run-review (this file) and multi-branch codex review orchestration.

Final checks (run after every mode)

• Mode locked in one line at the start; no silent swaps.
• Exact target named (PR URL, branch comparison, PR number, commit SHA, or markdown file path).
• Output matches the mode's documented shape — no cross-contamination.
• No GitHub mutation unless the user explicitly authorized it (and authorization was per-action).
• No git push, gh pr create, gh pr review --request-changes, or gh api .../replies ran without explicit authorization.
• Voice: no gratitude, praise, apology, or agreement-before-verification anywhere in the output.
• All findings (Mode A) or items (Mode C) carry file:line evidence; Mode B carries ≥ 2 weaknesses + ≥ 1 reviewer question.
• Mode D output is surfaced verbatim or written to disk — never summarized away.
