Analysis Phase

name: analysis-phase description: Validates cross-artifact consistency and detects breaking changes during feature analysis. Use when running /analyze command, validating spec-plan alignment, checking task-implementation consistency, or identifying API/database/UI breaking changes before deployment. (project) allowed-tools: Read, Edit, Grep, Bash

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

Inputs: spec.md, plan.md, tasks.md Outputs: analysis-report.md

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

See references/examples.md for grep commands.

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)

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.

Cross-reference:

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

Verify all dependencies documented and accounted for.

# 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

• 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)

Why: Breaking changes missed in analysis cause production issues post-deployment

Why: Missing mappings lead to incomplete implementation

Why: Undocumented dependencies cause integration failures

Why: Actionable findings enable quick remediation

• 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)
