Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is an excellent skill description that hits all the marks. It provides specific concrete actions, comprehensive natural trigger terms covering common user phrasings, explicit 'Use when' guidance, and a clearly distinct niche focused on PR description generation and review documentation.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Generate structured PR descriptions from diffs', 'add review checklists', 'risk assessments', and 'test coverage summaries'. These are all distinct, concrete capabilities. | 3 / 3 |
Completeness | Clearly answers both 'what' (generate structured PR descriptions, add checklists, risk assessments, test coverage summaries) and 'when' with an explicit 'Use when...' clause listing specific trigger phrases. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger terms users would say: 'write a PR description', 'improve this PR', 'summarize my changes', 'PR review', 'pull request', 'document a diff for reviewers'. Covers both abbreviation (PR) and full form (pull request). | 3 / 3 |
Distinctiveness Conflict Risk | Clearly occupies a distinct niche around PR descriptions and review documentation. The specific triggers like 'PR description', 'pull request', 'document a diff for reviewers' are unlikely to conflict with general code review or git commit message skills. | 3 / 3 |

Implementation
87%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-crafted skill that provides concrete, actionable guidance for generating PR descriptions. The template and checklist rules are immediately usable and the content is efficiently organized. The main gap is the lack of a validation/verification step in the workflow to ensure the generated description accurately reflects the diff.
Suggestions
Add a validation step after generating the PR description, e.g., 'Cross-check the Changes table against `git diff --stat` output to ensure no files are missing or miscategorized.'
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient. It doesn't explain what PRs are or how git works—it assumes Claude's competence. Every section serves a clear purpose with no padding or unnecessary exposition. | 3 / 3 |
Actionability | Provides a concrete markdown template that's copy-paste ready, specific git commands, a clear categorization scheme, and detailed checklist rules with specific thresholds (>500 lines, >20 files). The review checklist rules table maps file categories to concrete items. | 3 / 3 |
Workflow Clarity | The 5-step workflow is clearly sequenced, and the large PR splitting guidance is helpful. However, there's no explicit validation checkpoint—no step to verify the generated description matches the actual diff, no feedback loop for checking completeness or accuracy of the categorization against the real changes. | 2 / 3 |
Progressive Disclosure | Content is well-structured with clear sections (workflow, template, checklist rules, splitting guidance). References to external resources are one level deep and clearly signaled. The inline content is appropriately scoped for a SKILL.md overview. | 3 / 3 |
