75%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, actionable skill: the git workflow is concrete and includes a genuinely non-obvious insight (diffing boundary SHAs instead of date filters), and the report template plus good/bad writing examples make the output unambiguous. The main improvements are removing the frontmatter-duplicating intro sections, fixing the step-6 command that contradicts step 2's own guidance, and generalizing the hardcoded month-end date.
Suggestions
Drop or merge the "What this skill does" and "When to use this skill" sections into one or two lines, since they repeat the frontmatter description.
Fix the step-6 contributor-count command to use the same boundary-SHA range as step 2 instead of --since/--until, which the skill itself warns against; also generalize "YYYY-MM-31" (e.g., use the first day of the next month) so it works for 30-day and 28-day months.
Move the Writing Guidelines section (good/bad examples and per-item format) into a references file to slim the main body, and add a light verification step such as cross-checking the reported commit and contributor counts against the git log output.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is efficient overall with concrete commands and no explanations of concepts Claude already knows, but the "What this skill does" and "When to use this skill" sections largely duplicate the frontmatter description and could be trimmed. This is the minor-instances-of-over-explanation case rather than the lean anchor-5 case. | 4 / 5 |
Actionability | Guidance is mostly executable: real git commands (rev-list boundary SHAs, log with grep filters, format strings) plus a copy-paste-ready report template and per-item example. A minor gap is that the step-6 contributor-count command uses --since/--until, contradicting the skill's own step-2 warning against those filters, and the boundary-SHA snippet hardcodes "YYYY-MM-31" which is invalid for shorter months. | 4 / 5 |
Workflow Clarity | A clear 7-step sequence with concrete commands, noise-filtering guidance, and edge-case handling including a user-consultation loop for commits that don't fit categories. It stops short of anchor 5 because there is no explicit validation step for the generated report (e.g., verifying commit counts against the log or confirming the output file), though the operation is read-only so the destructive-operation cap does not apply. | 4 / 5 |
Progressive Disclosure | The single-file body (~197 lines) is well-sectioned and self-contained with no dangling or nested references, which is good structure. It exceeds the under-50-line simple-skill exception, and content such as the writing guidelines and example good/bad phrasings could plausibly live in a reference file, leaving minor organization gaps rather than the ideal anchor-5 split. | 4 / 5 |
