Conciseness

The workflow steps are largely efficient and specific, but the body contains clear redundancy: the full report structure is spelled out twice (step 10's 9-section outline and again in 'Output Format' as a markdown skeleton) even though references/report-template.md holds the full template, and 'Best Practices'/'Troubleshooting' sections pad with generic bullets like 'Be specific and detailed' and 'Use clear, consistent terminology'. This matches 'mostly efficient but includes some unnecessary explanation or could be tightened'; not a 2 because the core workflow content is substantive and specific rather than explanation of things Claude already knows.

Actionability

Concrete executable guidance is present: the automated command 'python scripts/analyze_code_impact.py <repo_path>' (script exists), four named mapping strategies with a worked example mapping ('Add user authentication' → auth.py, user.py, test_auth.py), and concrete filled-in example report snippets (e.g. 'auth.py::AuthManager.login() - Add 2FA verification step'). Matches 'mostly executable guidance; concrete code or commands with minor gaps'; not a 5 because the manual analysis steps and dependency-analysis guidance remain high-level descriptions rather than concrete commands.

Workflow Clarity

The 11-step workflow is clearly sequenced from input verification ('Requirements are readable... Repository path is valid') through analysis, mapping, and report generation, ending with a review checklist ('Verify completeness... Check accuracy... Refine report') — matching 'clear sequence with most checkpoints present'. Not a 5 because validation is checklist-style rather than a validate-fix-retry feedback loop (e.g. no instruction to re-run the impact script or re-verify mappings when review finds gaps); not a 3 because checkpoints are explicit at both entry (verify inputs) and exit (review and refine).

Progressive Disclosure

References exist, are real files, one level deep, and clearly signaled ('See [analysis-patterns.md](references/analysis-patterns.md) for detailed comparison strategies', 'See [report-template.md](references/report-template.md) for full template'). However, content that clearly belongs in the reference files is inlined: the report outline appears twice in SKILL.md (step 10 and Output Format) despite the dedicated template file, matching 'content that should be separate is inline'. Not a 4 because this duplication is more than a minor organization gap; not a 2 because the file structure itself is well-organized with clearly signaled references and a working script.

Specificity

Quotes like 'Compares old and new requirement documents, analyzes code repository impact, and generates detailed modification plans' plus six enumerated concrete actions (compare versions, map changes to components, identify modify/delete/add, analyze dependencies, assess test impact, generate Markdown plans) provide comprehensive, specific coverage — matching the anchor for multiple concrete actions. Not a 4 because there are no meaningful coverage gaps; the actions span the full workflow from comparison to report generation.

Completeness

The description explicitly answers both 'what' ('Compares old and new requirement documents, analyzes code repository impact, and generates detailed modification plans') and 'when' with concrete trigger phrases ('Use when Claude needs to: (1) Compare requirement versions... (6) Generate comprehensive modification plans'). This matches the anchor for clearly and explicitly answering both; it also notes supported formats ('Supports text/Markdown requirements').

Trigger Term Quality

Natural trigger phrases are present ('Compare requirement versions', 'Map requirement changes to code components', 'Assess test impact', 'requirement documents', 'modification plans') — good keyword coverage matching the 'a few natural terms missing' anchor. Not a 5 because common synonyms a user might actually say — 'spec', 'specification', 'PRD', 'user stories', 'diff' — are absent; not a 3 because the enumerated use-cases are natural phrasings users would say, not jargon.

Distinctiveness Conflict Risk

The requirement-version-comparison and modification-plan niche has distinct triggers unlikely to fire for unrelated skills — 'mostly distinct; minor overlap risk' fits. Not a 5 because terms like 'analyzes code repository impact' and 'assess test impact' have minor overlap with generic code-review or impact-analysis skills; not a 3 because the core trigger (comparing two requirement versions) is clearly distinct.
