- Path to analyze (defaults to current directory) 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- Check for outdated information Compare modified date with recent git commits Look for references to deprecated patterns Validate file paths and references exist 2.3 Best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] | | .claude/rules/ | ✅/❌ | N files | [list issues] | | ADRs | ✅/❌ | N files | [list issues] | | PRDs | ✅/❌ | N files | [list issues] | | PRPs | ✅/❌ | N files | [list issues] | 8.2 Quality Score Calculate an overall quality score: Category Score (0-10) Notes Structure X File organization, naming Completeness X Required sections present Freshness X Recent updates, git sync Standards Compliance X Frontmatter, format Content Quality X Clarity, specificity Overall X Average score Rating Guide : 9-10: Excellent - Well-maintained, comprehensive 7-8: Good - Minor improvements needed 5-6: Fair - Several issues to address 3-4: Poor - Major gaps or outdated 0-2: Critical - Missing or severely lacking 8.3 Issues and Recommendations Categorize findings: Critical Issues (must fix): Missing required documentation Severe structural problems Completely outdated information Warnings (should fix): Stale documentation (>6 months) Missing frontmatter Incomplete sections Minor structural issues Suggestions (nice to have): Additional documentation that would help Improved organization Better cross-referencing Enhanced examples 8.4 Actionable Recommendations For each issue, provide specific guidance:
