Reviewing Plan Artifacts

Overview

Find gaps in planning artifacts and generate issues that need resolution before proceeding to the next phase. Focus on design completeness and quality, not implementation details. This skill provides phase-specific review criteria for the Devil's Advocate.

When to Use

• Reviewing requirements.md + constraints.md after T0 (techspec core) phase completion
• Reviewing nfrs.md + integrations.md + data-sensitivity.md after T1 (techspec supplementary) phase completion
• Reviewing research.md after B0 phase completion
• Reviewing data-model.md after B1 phase completion
• Reviewing contracts/ after B2 phase completion
• Validating cross-artifact consistency before task generation
• When plan architect or technical analyst requests artifact review
• Quality gate checks before phase transitions

When NOT to Use

• Implementation code review - Use code review tools instead
• Task artifact review - Use humaninloop:validation-task-artifacts instead
• Specification review - Use humaninloop:analysis-specifications instead
• Constitution review - Use humaninloop:validation-constitution instead
• During active drafting - Wait for artifact completion before review

Review Focus by Phase

Each phase has specific checks to execute. The checks identify Critical, Important, and Minor issues.

Phase	Focus Area	Key Checks
A0	Codebase Discovery	Coverage, entity/endpoint detection, collision assessment
T0	Techspec Core	FR coverage, orphan TRs, testable criteria, sourced constraints
T1	Techspec Supplementary	NFR measurability, integration completeness, data classification
B0	Research	Marker resolution, alternatives, rationale quality
B1	Data Model	Entity coverage, relationships, PII identification
B2	Contracts	Endpoint coverage, schemas, error handling
B3	Cross-Artifact	Alignment, consistency, traceability

See PHASE-CHECKLISTS.md for detailed phase-specific checklists and key questions.

Issue Classification

Issues are classified by severity to determine appropriate action:

Severity	Definition	Action
Critical	Blocks progress; must resolve	Return to responsible agent
Important	Significant gap; should resolve	Flag for this iteration
Minor	Polish item; can defer	Note for later

See ISSUE-TEMPLATES.md for severity classification rules, issue documentation formats, and report templates.

Review Process

Step 1: Gather Context

Read and understand:

• The artifact being reviewed
• The spec requirements it should satisfy
• Previous artifacts (for consistency checks)
• Constitution principles (for compliance)

Step 2: Execute Checks

For each check in the phase-specific checklist:

1. Ask the question
2. Look for evidence in the artifact
3. If issue found, classify severity
4. Document the issue

Step 3: Cross-Reference

• Check traceability (can trace requirement -> artifact)
• Check consistency (artifacts agree with each other)
• Check completeness (nothing obviously missing)

Step 4: Generate Report

• Classify verdict based on issues found
• Document all issues with evidence
• Provide specific, actionable suggestions
• Acknowledge what was done well

Incremental Review Mode

For phases after the first artifact (data-model, contracts), use incremental review to optimize time while preserving rigor.

Full Review (New Artifact Only)

• Execute ALL phase-specific checks from PHASE-CHECKLISTS.md
• Document issues with full evidence
• This is the primary focus—no shortcuts

Consistency Check (Previous Artifacts)

• Use the cross-artifact checklist in PHASE-CHECKLISTS.md
• Do NOT re-read previous artifacts in full
• Spot-check: entity names, requirement IDs, decision references
• Flag only inconsistencies between artifacts
• Time budget: 1-2 minutes per previous artifact

When to Escalate to Full Re-Review

• If 2+ consistency issues found → re-read that specific artifact
• If contradictions detected → flag for supervisor
• If unsure → note uncertainty in report, recommend targeted review

Report Format (Incremental Mode)

## Review Summary

| Aspect | Status |
|--------|--------|
| **New Artifact** | {artifact} - FULL REVIEW |
| **Previous Artifacts** | CONSISTENCY CHECK ONLY |

## New Artifact Issues

{Full issue documentation with evidence}

## Cross-Artifact Consistency

| Check | Status | Notes |
|-------|--------|-------|
| Entity names | Pass/Fail | {any mismatches} |
| Requirement IDs | Pass/Fail | {any gaps} |
| Decision alignment | Pass/Fail | {any contradictions} |

## Verdict

{ready / needs-revision / critical-gaps}

Phase Application

Phase	Full Review	Consistency Check
T0 (Techspec Core)	requirements.md, constraints.md	— (first techspec artifact)
T1 (Techspec Supplementary)	nfrs.md, integrations.md, data-sensitivity.md	requirements.md + constraints.md (2-3 min)
B0 (Research)	research.md	— (first plan artifact)
B1 (Data Model)	data-model.md	research.md (1-2 min)
B2 (Contracts)	contracts/, quickstart.md	research.md + data-model.md (2-3 min)

Verdict Criteria

Verdict	Criteria
ready	Zero Critical, zero Important issues
needs-revision	1-3 Important issues, fixable in one iteration
critical-gaps	1+ Critical or 4+ Important issues

Quality Checklist

Before finalizing review, verify:

• All phase-specific checks executed
• Issues properly classified by severity
• Evidence cited for each issue
• Suggested fixes are actionable
• Verdict matches issue severity
• Cross-artifact concerns noted
• Strengths acknowledged

Common Mistakes

Over-Classification of Severity

❌ Marking style issues as "Critical" ✅ Reserve Critical for issues that genuinely block progress

Missing Evidence

❌ "The data model is incomplete" ✅ "The data model is missing the User entity referenced in FR-003"

Vague Suggestions

❌ "Fix the contracts" ✅ "Add error response schema for 404 case in GET /users/{id}"

Reviewing Implementation Details

❌ Commenting on code patterns, variable names, or framework choices ✅ Focus on design completeness, traceability, and consistency

Skipping Cross-Artifact Checks

❌ Reviewing only the new artifact in isolation ✅ Always verify consistency with previous phase artifacts

Excessive Re-Reading

❌ Re-reading all previous artifacts in full for every review ✅ Use incremental review mode with targeted consistency checks
