Your Task

Perform a comprehensive documentation quality analysis using the following methodology:

Phase 1: Create Todo List

Create a structured todo list for tracking the analysis:

- Analyze CLAUDE.md structure and quality
- Check .claude/rules/ directory and standards
- Validate ADRs (Architecture Decision Records)
- Validate PRDs (Product Requirements Documents)
- Validate PRPs (Product Requirement Prompts)
- Check documentation freshness and git history
- Generate quality report with recommendations

Phase 2: CLAUDE.md Analysis

2.1 Check Existence and Structure

• Verify CLAUDE.md exists at project root
• Check for required YAML frontmatter:

  ---
  created: YYYY-MM-DD
  modified: YYYY-MM-DD
  reviewed: YYYY-MM-DD
  ---
  

2.2 Content Quality Checks

• Completeness: Does it provide clear project context?

  • Project structure overview
  • Development conventions
  • Key rules and guidelines
  • Plugin/tool references if applicable

• Clarity: Is it well-organized and readable?

  • Clear sections with headers
  • Proper markdown formatting
  • Tables for structured data
  • Examples where helpful

• Accuracy: Check for outdated information

  • Compare modified date with recent git commits
  • Look for references to deprecated patterns
  • Validate file paths and references exist

2.3 Best Practices

Check against CLAUDE.md standards:

• Should guide AI assistants on how to work with the codebase
• Include project structure explanation
• Reference key rules and conventions
• Point to additional documentation (ADRs, rules)
• Use tables for quick reference
• Keep focused and concise

Phase 3: .claude/rules/ Analysis

3.1 Directory Structure

• Verify .claude/rules/ directory exists
• List all rule files present
• Check for recommended core rules:
  • Architecture/design patterns
  • Coding standards
  • Development workflows
  • Testing requirements

3.2 Individual Rule Validation

For each rule file in .claude/rules/:

Required Frontmatter:

---
created: YYYY-MM-DD
modified: YYYY-MM-DD
reviewed: YYYY-MM-DD
name: docs-quality-check
---

Content Standards:

• Clear title and purpose
• Well-defined scope
• Specific, actionable guidance
• Examples where appropriate
• Related rules cross-referenced

3.3 Rules Organization

• Are rules properly categorized?
• Are there too many/too few rules?
• Is there duplication or conflict between rules?
• Are rule names descriptive and consistent?

Phase 4: ADR Validation

4.1 Check ADR Directory

• Verify docs/adrs/ or docs/adr/ exists
• Check for ADR index/README
• List all ADR files (should be numbered: 0001-title.md)

4.2 ADR Structure Validation

For each ADR, verify:

Naming Convention:

• Format: NNNN-kebab-case-title.md (e.g., 0001-plugin-architecture.md)
• Sequential numbering
• Descriptive titles

Required Sections (MADR format):

# ADR-NNNN: Title

**Date**: YYYY-MM
**Status**: Accepted | Superseded | Deprecated
**Deciders**: [who made the decision]

## Context
[The issue motivating this decision]

## Decision
[The change being proposed or made]

## Consequences
[What becomes easier or harder]

4.3 ADR Quality Checks

• Status accuracy: Are deprecated ADRs marked?
• Completeness: Do ADRs have all required sections?
• Relevance: Are ADRs still applicable to current codebase?
• Index maintenance: Is the ADR index up to date?

4.4 Coverage Analysis

• Do ADRs cover major architectural decisions?
• Are recent significant changes documented?
• Are there obvious undocumented decisions?

Phase 5: PRD Validation

5.1 Check PRD Directory

• Verify docs/prds/ or .claude/blueprints/prds/ exists
• List all PRD files

5.2 PRD Structure Validation

For each PRD, verify:

Frontmatter (if using Blueprint methodology):

---
created: YYYY-MM-DD
modified: YYYY-MM-DD
reviewed: YYYY-MM-DD
status: Draft | Active | Implemented | Archived
name: docs-quality-check
---

Required Sections:

• Executive Summary / Problem Statement
• Stakeholders & User Personas
• Functional Requirements
• Non-Functional Requirements
• Success Metrics
• Scope (In/Out of scope)
• Technical Considerations

5.3 PRD Quality Checks

• Clarity: Are requirements specific and measurable?
• Completeness: Are all key sections present?
• Status: Is the status field accurate?
• Traceability: Can requirements be traced to implementations?
• User focus: Are user needs clearly articulated?

Phase 6: PRP Validation

6.1 Check PRP Directory

• Verify docs/prps/ exists (Blueprint methodology)
• List all PRP files

6.2 PRP Structure Validation

For each PRP, verify:

Required Sections:

• Goal & Why
• Success Criteria (testable)
• Context (documentation refs, codebase intelligence, known gotchas)
• Implementation Blueprint (architecture, task breakdown)
• TDD Requirements (test strategy, critical test cases)
• Validation Gates (executable commands)
• Confidence Score (0-10 across dimensions)

6.3 PRP Quality Checks

• Specificity: Are file paths and code references explicit?
• Testability: Are success criteria measurable?
• Completeness: Does the confidence score match content quality?
• Actionability: Can this PRP be executed immediately?
• Context: Is there enough curated context for implementation?

Phase 7: Freshness Analysis

7.1 Check Last Modified Dates

For all documentation:

• Compare modified frontmatter dates with git history
• Identify stale documents (>6 months without review)
• Flag documents that should be reviewed based on related code changes

Use git to check activity:

# Check recent commits affecting docs
git log --since="6 months ago" --oneline -- docs/ .claude/ CLAUDE.md 2>/dev/null || echo "Not a git repo or no history"

# Check when documentation was last touched
git log -1 --format="%ai %s" -- CLAUDE.md 2>/dev/null || echo "No git history"

7.2 Cross-Reference with Code Changes

• Have there been major code changes without doc updates?
• Are ADRs current with actual architecture?
• Do PRDs reflect implemented features accurately?

Phase 8: Generate Quality Report

8.1 Documentation Inventory

Generate a summary table:

## Documentation Inventory

| Document Type | Status | Count | Issues |
|---------------|--------|-------|--------|
| CLAUDE.md | ✅/❌ | 1 | [list issues] |
