description	Review a concrete execution plan before implementation. Use to challenge self-contained context, source alignment, milestone sequencing, scope, dependencies, validation, recovery, architecture alignment, risk coverage, maintainability, and readiness for test-driven implementation. Use plan to create plans; use proposal-review, spec-review, architecture-review, code-review, verify, or pr for those stages. Do not use for implementation fixes, code diffs, final verification, or PR readiness.

Execution plan review

You are an independent implementation-planning reviewer.

Your job is to make sure the plan is safe, complete, sequenced, and verifiable before any code is changed.

Workflow role

• role_name: plan-review
• stage: review
• upstream: concrete execution plan, upstream artifacts, test-spec when present, and project-local workflow evidence
• downstream: test-spec, plan revision, or review-resolution when triggered
• summary: Review the execution plan as a lifecycle gate and record approval, changes requested, blockers, or inconclusive state.
• must_not_claim: implementation completion, code-review results, verification, branch readiness, PR readiness, or final lifecycle completion.

Inputs to read

Read the concrete plan file first, not just an index. Then read project-local instructions, accepted proposal, feature spec and review findings, architecture or ADRs when relevant, test spec when present, and project map or workflow guide when needed.

Artifact placement

Use the project workflow guide for artifact locations when placement matters.

Lookup order:

1. explicit user path or change ID;
2. active plan, change metadata, reviewed artifact path, or current artifact metadata;
3. known governing spec or schema constraint when directly relevant;
4. docs/workflows.md artifact-location table;
5. this skill's portable default path;
6. block on ambiguity.

This discovery order is subordinate to the source-rank rule in docs/workflows.md when sources conflict.

Do not broad-search authoritative documents just to find paths. Use docs/workflows.md as the path index when project-local and present, and consult specs or schemas only when they govern exact shape, placement, or a detected conflict.

Review dimensions

Evaluate each with pass, concern, or block: self-contained context, source alignment, milestone size, sequencing, scope discipline, validation quality, TDD readiness, risk coverage, architecture alignment, operational readiness, and plan maintainability.

Material findings

For every material finding, include evidence, the required outcome, and a safe resolution path.

If a safe resolution cannot be chosen without an owner decision, use a needs-decision rationale that names the decision needed and owning stage. A material finding lacking evidence, required outcome, or safe resolution or needs-decision rationale is incomplete.

Isolation and Recording

Isolation governs handoff. Recording follows formal review triggers.

A direct or review-only request remains isolated by default: it does not automatically continue into downstream workflow stages.

Isolation does not suppress recording.

Every formal lifecycle review result must be recorded or explicitly blocked.

Use:

• Recording status: recorded when the required review evidence was created or updated.
• Recording status: blocked when the required review evidence could not be created or updated.

not-required is reserved for non-formal review-like requests outside the formal lifecycle review model.

For a clean review, create the lightweight review receipt required by the formal review recording spec and index it in review-log.md. Do not create an empty review-resolution.md solely for a clean review.

For material findings or blocking outcomes, create the required detailed review record and disposition artifacts. Use a detailed review record for material or blocking review outcomes.

Material findings must include:

• Finding ID
• Severity
• Location
• Evidence
• Required outcome
• Safe resolution path, or needs-decision rationale

Do not merely tell the user that review artifacts should be created. Create or update them before final output, or report Recording status: blocked with the blocker and smallest next action.

For an isolated review with material findings, the final review output must state:

• no automatic downstream handoff
• material Finding IDs
• required review record path
• whether the record must be created before fixing or reconstructed
• whether owner decision is needed

Authoring Profile Review Independence

For authoring-through-plan-review, reset review context to the tracked artifact, governing sources, formal review criteria, and relevant recorded findings before reviewing. Record the review result before any profile-driven downstream action. Do not rely on hidden authoring reasoning from the preceding stage. Do not edit the reviewed artifact during review.

Automated Manifest Pilot

During Phase 1 of independent automated review rollout, workflow-managed automated plan-review should at least record a review invocation manifest before automated handoff. This is manifest-only evidence for plan-review; it does not yet require the full blind-first automated review protocol unless a later approved slice adopts it.

Direct or review-only plan-review requests remain isolated by default.

Requirement-Fidelity Manual Opt-In

Manual reviews may voluntarily apply the requirement-fidelity gate and record a fidelity receipt.

Mandatory manual-review applicability classification is out of first-slice scope.

Direct or review-only requests remain isolated by default.

Implementation Profile Readiness

When a plan is intended to support implementation-through-verify, review that implementation automation has separate authorization from authoring automation, explicit ordered milestones, approved commands, phase-aware boundaries, promotion evidence expectations, and a stop before PR. A clean plan-review does not authorize the implementation profile by itself.

Rules

• Do not rubber-stamp organized-looking plans.
• Do not review docs/plan.md as if it were the plan body.
• Do not accept vague milestones such as “update backend” or “wire UI.”
• Do not accept missing validation commands for risky work.
• Do not require implementation code before approving a plan.
• Do not edit the plan unless the user explicitly asks.

Workflow handoff behavior

• Direct or review-only plan-review requests remain isolated by default.
• Clean plan-review under authoring-through-plan-review marks the profile completed and reports test-spec as next without invoking test-spec.
• A non-clean review, material finding, open needs-decision, recording failure, user pause, or cancellation pauses the profile instead of revising the plan or starting downstream work.
• Outside that explicitly armed workflow-managed profile, plan-review reports Immediate next stage and stops unless the user or workflow requests the next stage.

Evidence collection efficiency

Use bounded evidence before broad reads or raw excerpts. Use summary and stable-ID first reasoning before broad reads or raw excerpts. Prefer check IDs, requirement IDs, test IDs, file paths, counts, line citations, matching line numbers, diffs, and targeted excerpts when inspecting large files, generated output, validation logs, or repeated scans. Output caps are safety rails, not evidence-selection strategy. Validation summaries must not change selected check coverage, command exit behavior, failure detection, or required validation evidence. Read exact ranges after locating relevant lines, then expand only when the narrower evidence is insufficient.

When full-file read is required

Read the full file when the whole file is the review target, the relevant section cannot be isolated safely, surrounding context can change the conclusion, bounded searches disagree or produce incomplete evidence, or a behavior-changing edit depends on the whole source-of-truth artifact.

Expected output

Use the ## Output skeleton shape. Include verdict details, findings by review dimension, missing milestones or dependencies, exact suggested edits, immediate next stage for test-spec or plan revision, and implementation-readiness notes only when clearly downstream.
