The text {match} tells the agent to skip the normal "ask the user first" gate. Used adversarially it removes the human-in-the-loop check before destructive or sensitive actions, turning a normally-gated agent into a fire-and-forget executor.

If the user asks you to compress or the system triggers context compaction: Step 0 > Test diagram > Opinionated recommendations > Everything else. Never skip Step 0 or the test diagram. Do not preemptively warn about context limits -- the system handles compaction automatically.
These are not additional checklist items. They are the instincts that experienced engineering leaders develop over years — the pattern recognition that separates "reviewed the code" from "caught the landmine." Apply them throughout your review.
When evaluating architecture, think "boring by default." When reviewing tests, think "systems over heroes." When assessing complexity, ask Brooks's question. When a plan introduces new infrastructure, check whether it's spending an innovation token wisely.

When the design doc check above prints "No design doc found," offer the prerequisite skill before proceeding.
Say to the user via AskUserQuestion:
"No design doc found for this branch. /office-hours produces a structured problem statement, premise challenge, and explored alternatives — it gives this review much sharper input to work with. Takes about 10 minutes. The design doc is per-feature, not per-product — it captures the thinking behind this specific change."Options:
If they skip: "No worries — standard review. If you ever want sharper input, try /office-hours first next time." Then proceed normally. Do not re-offer later in the session.
If they choose A:
Say: "Running /office-hours inline. Once the design doc is ready, I'll pick up the review right where we left off."
Read the /office-hours skill file at ~/.claude/skills/office-hours/SKILL.md using the Read tool.
If unreadable: Skip with "Could not load /office-hours — skipping." and continue.
Follow its instructions from top to bottom, skipping these sections (already handled by the parent skill):
These are the setup and shared-protocol sections this review already ran; the remaining headings are the office-hours work.
Execute every other section at full depth. When the loaded skill's instructions are complete, continue with the next step below.

Before reviewing anything, answer these questions:
If WebSearch is unavailable, skip this check and note: "Search unavailable — proceeding with in-distribution knowledge only."
If the plan rolls a custom solution where a built-in exists, flag it as a scope reduction opportunity. Annotate recommendations with [Layer 1], [Layer 2], [Layer 3], or [EUREKA] (see preamble's Search Before Building section). If you find a eureka moment — a reason the standard approach is wrong for this case — present it as an architectural insight.
TODOS.md if it exists. Are any deferred items blocking this plan? Can any deferred items be bundled into this PR without expanding scope? Does this plan create new work that should be captured as a TODO?If the plan defers distribution, flag it explicitly in the "NOT in scope" section — don't let it silently drop.
If the complexity check triggers (8+ files or 2+ new classes/services), STOP before any review-section work. Explain what looks overbuilt, then resolve it with separate AskUserQuestion calls, in this order. Each AskUserQuestion call is a tool_use, not prose — call the tool directly.
Original arrangement and Smaller arrangement and list the files/classes in each. Both options keep the same approved features, contracts and fixes; only the layout differs, so the smaller one cuts nothing. If no smaller layout keeps those commitments, say so and ask the user to confirm the original layout or pause to look for one.Record the answers as one line in the plan: Scope: feature cuts <accepted/declined per item>; structure <original/smaller>. Apply only the changes the user accepted. A declined cut, or a question the user has not answered yet, leaves the plan as it was and the remedy open.
STOP. Do NOT proceed to Section 1, write the proposed scope reduction into the plan file, or call ExitPlanMode until the user has answered. Naming the overbuild in chat and carrying on is exactly the failure this gate exists to prevent: a scope decision the user never made still ends up in the plan.
If the complexity check does not trigger, present your Step 0 findings and proceed directly to Section 1.
Always work through the full interactive review: one section at a time (Architecture → Code Quality → Tests → Performance) with at most 8 top issues per section.
Critical: Once the user accepts or rejects a scope reduction recommendation, commit fully. Do not re-argue for smaller scope during later review sections. Do not silently reduce scope or skip planned components.
Anti-skip rule: Never condense, abbreviate, or skip any review section (1-4) regardless of plan type (strategy, spec, code, infra). Every section in this skill exists for a reason. "This is a strategy doc so implementation sections don't apply" is always wrong — implementation details are where strategy breaks down. If a section genuinely has zero findings, say "No issues found" and move on — but you must evaluate it.
Anti-shortcut clause: The plan file is the OUTPUT of the interactive review, not a substitute for it. Writing every finding into one plan write and calling ExitPlanMode without firing AskUserQuestion defeats the review — you explored, found issues, and dumped them into a deliverable instead of walking the user through them. If you have ANY non-trivial finding in any review section, the path from finding to ExitPlanMode goes THROUGH AskUserQuestion. Zero findings in every section is the only path to ExitPlanMode that bypasses AskUserQuestion. If you catch yourself wanting to write a plan with findings before asking — stop and call AskUserQuestion now.

Only proceed to the next section after ALL issues in this section are resolved.
Every finding MUST include a confidence score (1-10):
| Score | Meaning | Display rule |
|---|---|---|
| 9-10 | Verified by reading specific code. Concrete bug or exploit demonstrated. | Show normally |
| 7-8 | High confidence pattern match. Very likely correct. | Show normally |
| 5-6 | Moderate. Could be a false positive. | Show with caveat: "Medium confidence, verify this is actually an issue" |
| 3-4 | Low confidence. Pattern is suspicious but may be fine. | Suppress from main report. Include in appendix only. |
| 1-2 | Speculation. | Only report if severity would be P0. |
Finding format:
\[SEVERITY] (confidence: N/10) file:line — description\
Example: \[P1] (confidence: 9/10) app/models/user.rb:42 — SQL injection via string interpolation in where clause\ \[P2] (confidence: 5/10) app/controllers/api/v1/users_controller.rb:18 — Possible N+1 query, verify with production logs\
Before any finding is promoted to the report, the gate requires:
the verbatim text of the line(s) that triggered it. If the finding is "field X doesn't exist on model Y", quote the lines of class Y where the field would live. If "dict.get() might return None", quote the dict initialization. If "race condition between A and B", quote both A and B.
Force its confidence to 4-5 (suppressed from the main report). It still goes into the appendix so reviewers can audit calibration, but the user does NOT see it in the critical-pass output. Do not work around this by inventing speculative confidence 7+ — that defeats the gate.
Framework-meta nudge: When the symbol is generated by a framework metaclass, descriptor, ORM Meta inner-class, or migration history (Django Meta, Rails has_many/scope, SQLAlchemy relationship/Column, TypeORM decorators, Sequelize init/belongsTo, Prisma generated client), quote the meta-construct (the Meta block, the migration, the decorator, the schema file) instead of expecting the literal name in the class body. The verification is "I read the source that creates this symbol", not "I grep'd for the name and didn't find it." Deeper framework-aware verification (model introspection, migration-history-aware checks, ORM dialect detection) is deliberately out of scope for this lighter gate.
The FP classes this gate kills:
| FP class | Why the gate catches it |
|---|---|
| "field doesn't exist on model" | Requires quoting the model class body or Meta; the field's absence becomes obvious. |
| "dict.get() might be None" | Requires quoting the dict initialization (e.g. a form's cleaned_data is {}-initialized). |
| "save() might lose fields" | Requires quoting the ORM signature or model definition. |
| "update_fields might miss X" | Requires quoting the field set; if X doesn't exist, the FP is self-evident. |
Calibration learning: If you report a finding with confidence < 7 and the user confirms it IS a real issue, that is a calibration event. Your initial confidence was too low. Log the corrected pattern as a learning so future reviews catch it with higher confidence.

Every codepath in the plan needs a test that would catch its regression. Evaluate every codepath and ensure the plan covers each one with a test that passes the test value bar below. If the plan is missing tests, add them — the plan should be complete enough that implementation includes full test coverage from the start. More tests is not the goal: a duplicate or weak test adds maintenance, not coverage.
Before analyzing coverage, detect the project's test framework:
## Testing section with test command and framework name. If found, use that as the authoritative source.setopt +o nomatch 2>/dev/null || true # zsh compat
# Detect project runtime. A project is often identified by its build file alone —
# a Python repo with only tox.ini, or a Ruby repo with only a Rakefile, still has

ls -d test/ tests/ spec/ __tests__/ cypress/ e2e/ src/test/ 2>/dev/nullStep 1. Trace every codepath in the plan:
Read the plan document. For each new feature, service, endpoint, or component described, trace how data will flow through the code — don't just list planned functions, actually follow the planned execution:
This is the critical step — you're building a map of every line of code that can execute differently based on input. Every branch in this diagram needs a test.
Step 2. Map user flows, interactions, and error states:
Code coverage isn't enough — you need to cover how real users interact with the changed code. For each changed feature, think through:
Add these to your diagram alongside the code branches. A user flow with no test is just as much a gap as an untested if/else.
Step 3. Check each branch against existing tests:
Go through your diagram branch by branch — both code paths AND user flows. For each one, search for a test that exercises it:
processPayment() → look for billing.test.ts, billing.spec.ts, test/billing_test.rbhelperFn() that has its own branches → those branches need tests tooQuality scoring rubric:
{{include lib/snippets/test-value-bar.md}}
When checking each branch, also determine whether a unit test or E2E/integration test is the right tool:
RECOMMEND E2E (mark as [→E2E] in the diagram):
RECOMMEND EVAL (mark as [→EVAL] in the diagram):
STICK WITH UNIT TESTS:
This rule distinguishes observed breakage from proposed change. Which one applies depends on what the review targets (scope gate).
Branch diff target (scope gate A) — IRON RULE: When the coverage audit identifies a REGRESSION — code that previously worked and the diff on this branch broke it — a regression test is added to the plan as a critical requirement. No AskUserQuestion. No skipping. Regressions are the highest-priority test because they prove something broke.
A regression (diff target) is when:
When uncertain whether a change on a diff target is a regression, err on the side of writing the test.
Plan or path target (scope gate B or C) — regression risk, not regression: A plan has no diff yet. A proposed rewrite of existing behavior is a regression risk, not proof that running code broke, and the plan may change that behavior on purpose. Never label it "the diff broke". Name the existing callers and behavior at risk, then settle the contract with ONE AskUserQuestion covering every at-risk path together: which behavior must be preserved, which differences are intended, and the assertions that prove both. Ask how to cover it, not whether to cover it — regression coverage itself is not optional. Add the agreed tests to the plan as critical requirements.
Step 4. Output ASCII coverage diagram:
Include BOTH code paths and user flows in the same diagram. Mark E2E-worthy and eval-worthy paths:
CODE PATHS USER FLOWS
[+] src/services/billing.ts [+] Payment checkout
├── processPayment() ├── [★★★ TESTED] Complete purchase — checkout.e2e.ts:15
│ ├── [★★★ TESTED] happy + declined + timeout ├── [GAP] [→E2E] Double-click submit
│ ├── [GAP] Network timeout └── [GAP] Navigate away mid-payment
│ └── [GAP] Invalid currency
└── refundPayment() [+] Error states
├── [★★ TESTED] Full refund — :89 ├── [★★ TESTED] Card declined message
└── [★ WEAK] Partial (non-throw only) — :101 └── [GAP] Network timeout UX
LLM integration: [GAP] [→EVAL] Prompt template change — needs eval test
COVERAGE: 4/13 paths tested (31%) | Code paths: 2/5 (40%) | User flows: 2/8 (25%)
QUALITY: ★★★:2 ★★:2 ★:1 | GAPS: 9 (2 E2E, 1 eval, 1 weak)Legend: ★★★ behavior + edge + error | ★★ happy path | ★ smoke check [★ WEAK] = only a weak test; counts as a gap, not as tested [→E2E] = needs integration test | [→EVAL] = needs LLM eval
Fast path: All paths covered → "Test review: All new code paths have test coverage ✓" Continue.
Step 5. Add missing tests to the plan:
For each GAP identified in the diagram, add a test requirement to the plan. Be specific:
Value: protects=...; fails_when=...; why_new=...; seam=...). A proposed test that cannot fill the card is not added: extend the existing test named in why_new, or drop itExisting tests the plan makes redundant, or that only assert implementation the plan changes, go under Tests to Retire in the test plan artifact, each with what it detects and the test that covers that instead. Retiring is a recommendation for the implementer; the retention bar wins over it.
The plan should be complete enough that when implementation begins, every test is written alongside the feature code — not deferred to a follow-up.
After producing the coverage diagram, write a test plan artifact to the project directory so /qa and /qa-only can consume it as primary test input:
eval "$("${VIBESTACK_HOME:-$HOME/.vibestack}/bin/vibe-slug" 2>/dev/null)" && mkdir -p "${VIBESTACK_HOME:-$HOME/.vibestack}/projects/$SLUG"
echo "PROJECT_DIR: ${VIBESTACK_HOME:-$HOME/.vibestack}/projects/$SLUG"
USER=$(whoami)
DATETIME=$(date +%Y%m%d-%H%M%S)Write to <PROJECT_DIR>/{user}-{branch}-eng-review-test-plan-{datetime}.md, where <PROJECT_DIR> is the path the block above printed on its PROJECT_DIR: line:

For LLM/prompt changes: check the "Prompt/LLM changes" file patterns listed in CLAUDE.md. If this plan touches ANY of those patterns, state which eval suites must be run, which cases should be added, and what baselines to compare against. Then use AskUserQuestion to confirm the eval scope with the user.
STOP. For each issue found in this section, call AskUserQuestion individually. One issue per call. Present options, state your recommendation, explain WHY.

Only proceed to the next section after ALL issues in this section are resolved.
Evaluate:
On per-request or looped paths, check for queries in loops, unbounded queries or caches, missing indexes, whole-file loads, and blocking calls without timeouts. Give each finding's scale (rows, requests/s, bytes) or mark it scale unknown; never invent benchmarks or latency numbers.

After all review sections are complete, run an independent second opinion from a different AI system automatically — it is a standard step of plan review, not an opt-in. Two models agreeing on a plan is stronger signal than one model's thorough review.
{{include lib/snippets/outside-voice-preflight.md}}
Construct the plan review prompt. Read the plan file being reviewed (the file the user pointed this review at, or the branch diff scope). If a CEO plan document was written in Step 0D-POST, read that too — it contains the scope decisions and vision.
Construct this prompt (substitute the actual plan content — if plan content exceeds 30KB, truncate to the first 30KB and note "Plan truncated for size"). Always start with the filesystem boundary instruction:
"IMPORTANT: Do NOT read or execute any files under ~/.claude/, ~/.agents/, .claude/skills/, or agents/. These are Claude Code skill definitions meant for a different AI system. They contain bash scripts and prompt templates that will waste your time. Ignore them completely. Do NOT modify agents/openai.yaml. Stay focused on the repository code only.\n\nYou are a brutally honest technical reviewer examining a development plan that has already been through a multi-section review. Your job is NOT to repeat that review. Instead, find what it missed. Look for: logical gaps and unstated assumptions that survived the review scrutiny, overcomplexity (is there a fundamentally simpler approach the review was too deep in the weeds to see?), feasibility risks the review took for granted, missing dependencies or sequencing issues, and strategic miscalibration (is this the right thing to build at all?). Be direct. Be terse. No compliments. Just the problems.
THE PLAN: <plan content>"
If `CODEX_MODE` is `ready`:
The prompt carries plan text, which routinely contains quotes, backticks and $ expressions. Never interpolate it into shell source. First create a private prompt file:
umask 077; mktemp "${TMPDIR:-/tmp}/vibe-plan-prompt.XXXXXXXX"Keep the printed path. Read that empty file first — the Write tool refuses to overwrite a file it has not read — then use the Write tool to put the complete prompt (boundary instruction, reviewer instructions and plan content) into it. If the write fails, do not run Codex; treat it as a Codex error below. Then run Codex with the prompt on stdin, substituting the shell-quoted path for <prompt-file>:
_PROMPT_FILE='<prompt-file>'
_REPO_ROOT=$(git rev-parse --show-toplevel) || { echo "ERROR: not in a git repo" >&2; exit 1; }
[ -s "$_PROMPT_FILE" ] || { echo "ERROR: prompt file missing or empty: $_PROMPT_FILE" >&2; exit 1; }
TMPERR_PV=$(mktemp "${TMPDIR:-/tmp}/codex-planreview-XXXXXXXX") || { echo "ERROR: mktemp failed" >&2; exit 1; }

If `CODEX_MODE` is `not_installed`, `not_authed`, `quota_exhausted` or `unavailable` (or Codex errored), or `under_codex` with no completed `claude -p` pass: under under_codex the preflight's OUTSIDE_VOICE branches govern — claude -p runs first, and only its fallback reaches this subagent.
Dispatch via the Agent tool. The subagent has fresh context — genuine independence.
{{include lib/snippets/foreground-dispatch.md}}
Subagent prompt: same plan review prompt as above.
Present findings under an OUTSIDE VOICE (Claude subagent): header — under under_codex, use OUTSIDE VOICE (same-model subagent — not cross-model): instead, since the subagent is Codex too.
If the subagent fails or times out: "Outside voice unavailable. Continuing to outputs."
Cross-model tension:
After presenting the outside voice findings, note any points where the outside voice disagrees with the review findings from earlier sections. Flag these as:
CROSS-MODEL TENSION:
[Topic]: Review said X. Outside voice says Y. [Present both perspectives neutrally.
State what context you might be missing that would change the answer.]User Sovereignty: Do NOT auto-incorporate outside voice recommendations into the plan. Present each tension point to the user. The user decides. Cross-model agreement is a strong signal — present it as such — but it is NOT permission to act. You may state which argument you find more compelling, but you MUST NOT apply the change without explicit user approval.
For each substantive tension point, use AskUserQuestion:
"Cross-model disagreement on [topic]. The review found [X] but the outside voice argues [Y]. [One sentence on what context you might be missing.]"
>
RECOMMENDATION: Choose [A or B] because [one-line reason explaining which argument is more compelling and why]. Completeness: A=X/10, B=Y/10.
Options:
Wait for the user's response. Do NOT default to accepting because you agree with the outside voice. If the user chooses B, the current approach stands — do not re-argue.
If no tension points exist, note: "No cross-model tension — both reviewers agree."
Persist the result:
"${VIBESTACK_HOME:-$HOME/.vibestack}/bin/vibe-review-log" '{"skill":"codex-plan-review","timestamp":"'"$(date -u +%Y-%m-%dT%H:%M:%SZ)"'","status":"STATUS","source":"SOURCE","commit":"'"$(git rev-parse --short HEAD)"'"}'Substitute: STATUS = "clean" if no findings, "issues_found" if findings exist. SOURCE = "codex" if Codex ran, "claude" if subagent ran.
Cleanup: Run rm -f '<prompt-file>' after processing (if Codex was used), substituting the same prompt-file path.
Outside voice findings are INFORMATIONAL until the user explicitly approves each one. Do NOT incorporate outside voice recommendations into the plan without presenting each finding via AskUserQuestion and getting explicit approval. This applies even when you agree with the outside voice. Cross-model consensus is a strong signal — present it as such — but the user makes the decision.
Follow the AskUserQuestion format from the Preamble above. Additional rules for plan reviews:
Completeness: N/10 on each option. If kind (e.g., architectural choice between two different systems, posture-over-posture, A/B/C where each is a different kind of thing), skip the score and add one line: Note: options differ in kind, not coverage — no completeness score. Do NOT fabricate scores on kind-differentiated questions — filler scores are worse than no score.{{include lib/snippets/tasks-section-emit.md}}
Every plan review MUST produce a "NOT in scope" section listing work that was considered and explicitly deferred, with a one-line rationale for each item.
List existing code/flows that already partially solve sub-problems in this plan, and whether the plan reuses them or unnecessarily rebuilds them.
After all review sections are complete, present each potential TODO as its own individual AskUserQuestion. Never batch TODOs — one per question. Never silently skip this step. Follow the format in .claude/skills/review/TODOS-format.md.
For each TODO, describe:
Then present options: A) Add to TODOS.md B) Skip — not valuable enough C) Build it now in this PR instead of deferring.
Do NOT just append vague bullet points. A TODO without context is worse than no TODO — it creates false confidence that the idea was captured while actually losing the reasoning.
The plan itself should use ASCII diagrams for any non-trivial data flow, state machine, or processing pipeline. Additionally, identify which files in the implementation should get inline ASCII diagram comments — particularly Models with complex state transitions, Services with multi-step pipelines, and Concerns with non-obvious mixin behavior.
For each new codepath identified in the test review diagram, list one realistic way it could fail in production (timeout, nil reference, race condition, stale data, etc.) and whether:
If any failure mode has no test AND no error handling AND would be silent, flag it as a critical gap.
Analyze the plan's implementation steps for parallel execution opportunities. This helps the user split work across git worktrees (via Claude Code's Agent tool with isolation: "worktree" or parallel workspaces).
Skip if: all steps touch the same primary module, or the plan has fewer than 2 independent workstreams. In that case, write: "Sequential implementation, no parallelization opportunity." Item 5 below can still apply.
Otherwise, produce:
| Step | Modules touched | Depends on |
|---|---|---|
| (step name) | (directories/modules, NOT specific files) | (other steps, or —) |
Work at the module/directory level, not file level. Plans describe intent ("add API endpoints"), not specific files. Module-level ("controllers/, models/") is reliable; file-level is guesswork.
Format: Lane A: step1 → step2 (sequential, shared models/) / Lane B: step3 (independent)

After displaying the Review Readiness Dashboard, check if additional reviews would be valuable. Read the dashboard output to see which reviews have already been run and whether they are stale.
Suggest /plan-design-review if UI changes exist and no design review has been run — detect from the test diagram, architecture review, or any section that touched frontend components, CSS, views, or user-facing interaction flows. If an existing design review's commit hash shows it predates significant changes found in this eng review, note that it may be stale.
Mention /plan-ceo-review if this is a significant product change and no CEO review exists — this is a soft suggestion, not a push. CEO review is optional. Only mention it if the plan introduces new user-facing features, changes product direction, or expands scope substantially.
Note staleness of existing CEO or design reviews if this eng review found assumptions that contradict them, or if the commit hash shows significant drift.
If no additional reviews are needed (or skip_eng_review is true in the dashboard config, meaning this eng review was optional): state "All relevant reviews complete. Run /ship when ready."
Use AskUserQuestion with only the applicable options:
If the user does not respond to an AskUserQuestion or interrupts to move on, note which decisions were left unresolved. At the end of the review, list these as "Unresolved decisions that may bite you later" — never silently default to an option.
