<objective> Validates cross-artifact consistency and detects breaking changes during the /analyze phase. Ensures spec requirements align with plan components, tasks match implementation, and breaking changes are identified before deployment. </objective>

<quick_start> Validate cross-artifact consistency and detect breaking changes:

•Check spec → plan → tasks alignment
•Detect breaking changes (API, database, UI, auth)
•Validate dependencies
•Generate analysis-report.md with findings

Inputs: spec.md, plan.md, tasks.md Outputs: analysis-report.md </quick_start>

<workflow> <step number="1"> **Check spec-plan consistency**

Read spec.md requirements, verify each has corresponding plan component. Flag missing mappings in analysis report.

See references/examples.md for grep commands. </step>

<step number="2"> **Verify task-implementation alignment**

Read plan.md components, verify each broken into tasks in tasks.md.

Validate:

•Each plan component has ≥1 task
•Task acceptance criteria match spec success criteria
•No orphaned tasks (tasks without plan component) </step>

<step number="3"> **Detect breaking changes**

Scan for patterns indicating breaking changes:

•API changes: Endpoint signature modifications, required parameter additions, response format changes
•Database changes: Schema modifications, required field additions, migrations affecting existing data
•UI changes: Component interface changes, prop requirement additions
•Auth changes: Permission model modifications, authentication flow changes

Flag with impact level (Low/Medium/High) using reference rubric. </step>

<step number="4"> **Validate dependencies**

Cross-reference:

•Imports and integrations mentioned in plan
•External dependencies in tasks
•Integration points in spec

Verify all dependencies documented and accounted for. </step>

<step number="5"> **Generate analysis report**

Create specs/NNN-slug/analysis-report.md:

# Analysis Report

## Consistency Check

- Spec-Plan: [✓/✗] Description
- Plan-Tasks: [✓/✗] Description

## Breaking Changes

- [High/Medium/Low] Description and impact

## Dependency Validation

- [✓/✗] Dependencies documented

## Recommendations

- Action items to fix inconsistencies

Update state.yaml: analysis.status = completed </step> </workflow>

<validation> After analysis, verify:

•All spec requirements have plan component coverage
•All plan components have task breakdown
•Breaking changes flagged with impact level (Low/Medium/High)
•Analysis report generated with actionable findings
•No orphaned artifacts (tasks without plan, plan without spec) </validation>

<anti_patterns> <pitfall name="missing_breaking_changes"> ❌ Don't: Assume no breaking changes without scanning ✅ Do: Explicitly check API signatures, database schema, required fields, auth changes

Why: Breaking changes missed in analysis cause production issues post-deployment </pitfall>

<pitfall name="inconsistent_artifacts"> **❌ Don't**: Assume spec and plan are aligned **✅ Do**: Explicitly validate each spec requirement has corresponding plan component

Why: Missing mappings lead to incomplete implementation </pitfall>

<pitfall name="no_cross_reference"> **❌ Don't**: Skip dependency validation **✅ Do**: Cross-reference all imports, integrations, external dependencies

Why: Undocumented dependencies cause integration failures </pitfall>

<pitfall name="vague_findings"> **❌ Don't**: Write vague findings like "inconsistencies found" **✅ Do**: Specify exact artifacts, line numbers, and recommended fixes

Why: Actionable findings enable quick remediation </pitfall> </anti_patterns>

<success_criteria>

• All spec requirements mapped to plan components (no gaps)
• All plan components broken into tasks (no orphans)
• Breaking changes documented with impact level (High/Medium/Low)
• Dependencies validated and documented
• analysis-report.md generated with actionable findings
• state.yaml updated (analysis.status = completed) </success_criteria>
