Review PRDs, brainstorm docs, tech plans, design docs, specs, or any planning document for issues. This skill should be used whenever the user wants feedback, critique, or a quality check on an existing planning or requirements document — even if they don't use the word "review." Common triggers include: "review the plan", "check the PRD", "critique my tech plan", "what's wrong with this plan", "poke holes in the requirements", "is this plan solid", "take a look at this spec", "give feedback on the brainstorm", or pointing to a doc file and asking if anything is off. Also triggers after writing a PRD or tech plan (to review what was just created), or when invoked by brainstorming or tech-planning skills. Do NOT trigger for code review (PRs, diffs, source files), writing/creating new plans, debugging, or reviewing non-planning documents (READMEs, CLAUDE.md, test coverage).

Plan Review
Reviews PRDs, brainstorms, and technical plans using dynamically selected reviewer personas. Spawns parallel sub-agents that return structured JSON, then merges and deduplicates findings into a single report.
When to Use
After writing a PRD
After writing a technical plan
When feedback is needed on any planning document
Can be invoked standalone or called by iterative:brainstorming/iterative:tech-planning skills
Priority Scale
All reviewers use HIGH/MEDIUM/LOW:
Level
Meaning
Action
HIGH
Blocks execution; cannot start the next step without resolving
Must fix before proceeding
MEDIUM
Creates risk; work can start but likely leads to rework or confusion
Should fix
LOW
Improvement opportunity; plan works but could be clearer or tighter
Author's discretion
Reviewers
6 personas in three tiers. See references/persona-catalog.md for the full catalog.
Document-type (exactly 1 — selected by document type):
Proposes abstractions, multi-layer architecture, plugin systems, or infrastructure ahead of need
feasibility-reviewer
Is a tech plan that proposes architecture, external integrations, or performance constraints
scope-guardian-reviewer
Is a PRD with multiple priority levels and potential conflicts, unclear scope boundaries, many requirements where goal alignment isn't obvious, or goals that don't connect to requirements
Review Scope
The document type naturally regulates the review. A simple PRD gets 2 reviewers (prd-reviewer + coherence-reviewer). A complex tech plan with architecture decisions gets 4 (tech-plan-reviewer + coherence-reviewer + skeptic-reviewer + feasibility-reviewer). No separate "mode" is needed.
How to Run
Stage 1: Identify document
Identify the document to review from argument, conversation context, or ask user. Determine the document type — PRD, brainstorm, or tech plan — from filename, content, and context. Treat brainstorm documents and PRDs synonymously. Record the document path and document type.
Read the full document content. This is needed for both reviewer selection and spawning.
Stage 2: Select reviewers
Read the document content from Stage 1. The document-type reviewer and coherence are automatic. For each conditional persona in the catalog (references/persona-catalog.md), decide whether the document warrants it. This is agent judgment, not keyword matching.
Announce the team before spawning:
Review team:
- prd-reviewer (document-type)
- coherence-reviewer (always)
- scope-guardian-reviewer — PRD has 12 requirements across 3 priority levels with dependency conflicts
This is progress reporting, not a blocking confirmation.
Stage 3: Spawn sub-agents
Spawn each selected reviewer as a parallel sub-agent using the template in references/subagent-template.md. Each sub-agent receives:
Their persona file content (identity, failure modes, calibration, suppress conditions)
The JSON output contract from references/findings-schema.json
Convert multiple reviewer JSON payloads into one deduplicated, confidence-gated finding set.
Validate. Check each output against the schema. Drop malformed findings (missing required fields). Record the drop count.
Confidence gate. Suppress findings below 0.50 confidence. Record the suppressed count.
Deduplicate. Compute fingerprint: normalize(section) + line_bucket(line, ±5) + normalize(title). When fingerprints match, merge: keep highest priority, keep highest confidence with strongest evidence, union evidence, note which reviewers flagged it.
Promote residual concerns. Scan residual_concerns for issues that overlap with findings from other reviewers or that describe concrete blocking risks (missing dependencies, unowned prerequisites, timeline impossibilities). Promote these to MEDIUM findings with confidence 0.55-0.65. A residual concern that corroborates an existing finding strengthens the case; one that identifies a distinct blocking risk deserves to be surfaced rather than buried.
Sort. Order by priority (HIGH first) → confidence (descending) → document order.
Collect coverage data. Union remaining (non-promoted) residual_concerns across reviewers.
Stage 5: Synthesize and present
Assemble the final report using the template in references/review-output-template.md:
Header. Document path, type, reviewer team with per-conditional justifications.
Findings. Grouped by priority (HIGH, MEDIUM, LOW). Each finding shows section, issue, reviewer(s), confidence.
Synthesis. Patterns, tensions between reviewers, quick wins. Not a binary verdict — plans don't have "ready/not ready." The synthesis helps the author decide what to address.
Do not include time estimates.
After Review
When invoked from iterative:brainstorming or iterative:tech-planning: return findings directly — the calling skill owns the fix loop and workflow transitions. Do not enter the standalone fix loop below.
When invoked standalone: run the standalone fix loop.
Standalone Fix Loop
After presenting the synthesized findings (Stage 5), offer to fix issues when running standalone. Plan fixes are text edits with low cascading risk — keep the loop simple.
If zero findings, the review is done — no further prompts needed.
Step 6: Fix Offer
Use the platform's interactive question tool — AskUserQuestion (Claude Code) or request_user_input (Codex). Both platforms provide an automatic "Other" free-form option — do not add one manually.
Present a single prompt listing all priority levels with findings. No intermediate "choose which..." step.
Claude Code — use AskUserQuestion with multiSelect: true:
When HIGH issues exist, pre-check the HIGH option:
☑ HIGH (Recommended) — N issues that block execution
☐ MEDIUM — N issues
☐ LOW — N issues
When only MEDIUM/LOW issues exist, nothing pre-checked:
☐ MEDIUM — N issues
☐ LOW — N issues
Only include priority levels that have findings.
Codex — use request_user_input (single-select, build combined options):
When HIGH issues exist:
Fix HIGH (Recommended) — N issues
Fix HIGH + MEDIUM — N issues
Fix all — N issues
Skip fixes
When only MEDIUM/LOW issues exist:
Fix MEDIUM only — N issues
Fix MEDIUM + LOW — N issues
Skip fixes
Only include options where findings exist at those levels. Omit options that would duplicate another (e.g., if no LOW, omit "Fix all" since it equals the line above).
Step 7: Apply Fixes
Fix only the selected priorities. Spawn a single subagent with the filtered findings, document path, and document type. The subagent applies targeted fixes, preserves the document's voice and decisions, and commits.
Wait for the subagent to complete.
Step 8: Done
After fixes land (or user skipped), present an interactive choice:
Another review round — fresh reviewers on the updated document
Done — review complete
If another round: run the full Stage 1–Step 8 flow again. No workflow transition options — the user knows what to do next.
Fallback
If the platform doesn't support parallel sub-agents, run reviewers sequentially. Everything else (stages, output format, merge pipeline) stays the same.
