Quality

Content

72%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is admirably concise and well-structured for a simple skill, but actionability and workflow clarity suffer from missing executable commands for PR/commit data sources and absent validation checkpoints for the scan window. Adding a concrete PR-data command and a verify-scan-window step would lift both dimensions.

Suggestions

Add an executable command for fetching PR labels/milestones (e.g., a `gh pr list` invocation) so all scan sources have concrete commands.

Insert a validation checkpoint that confirms <last-tag> resolves and the scan window is non-empty before categorizing.

Number the workflow steps (Scan -> Categorize -> Write draft -> Update state) so the sequence and the human-approval gate are explicit.

DimensionReasoningScore

Conciseness

Lean and efficient with no padding or explanation of concepts Claude already knows; every line (git command, categories, output files, rules) earns its place, matching the 'lean and efficient' anchor.

5 / 5

Actionability

Provides one concrete executable command ('git log --merges --oneline <last-tag>..HEAD') but 'PR labels and milestones' and 'Commit messages since last tag' lack executable commands (e.g., a gh CLI call), leaving incomplete concrete guidance.

3 / 5

Workflow Clarity

Sections imply a rough sequence (Scan -> Categories -> Output -> Rules) but there are no explicit checkpoints and no validation (e.g., confirm <last-tag> resolves, verify the scan window); the destructive/batch-adjacent publishing context caps workflow_clarity at 3.

3 / 5

Progressive Disclosure

Under 50 lines, single-purpose, well-organized into clear sections with no need for external references, so the simple-skill exception yields a 5; no bundle files exist to verify.

Description

58%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description clearly states concrete capabilities around scanning PRs and commits for release notes, but lacks an explicit 'Use when...' trigger clause, which caps completeness and leaves distinctiveness slightly below peak. It is specific and non-vague, just missing the activation guidance.

Suggestions

Add an explicit 'Use when...' clause naming natural trigger phrases like 'changelog', 'release notes', 'what changed since the last tag', or 'drafting release notes'.

Include synonyms and concrete artifacts (e.g., 'changelog', 'CHANGELOG.md', 'release notes', 'semver bump') to broaden trigger-term coverage.

Tighten the link between extracted 'signals' and the release-notes output to make the capability coverage more comprehensive.

DimensionReasoningScore

Specificity

Lists several concrete actions ('Scan merged PRs and commits since a given reference, extract titles, labels, types, and signals. Produces structured input') with only minor coverage gaps, matching the 'several specific actions' anchor; not a 5 because coverage of how signals feed drafting is not comprehensive.

4 / 5

Completeness

Has a clear 'what' but no 'Use when...' clause or equivalent trigger guidance, so per the missing-trigger cap completeness cannot exceed 3; 'when' is only weakly implied.

3 / 5

Trigger Term Quality

Contains relevant keywords ('merged PRs', 'commits', 'release notes') but misses common natural phrasings users say ('changelog', 'what changed since last release'), fitting the 'some relevant keywords but missing variations' anchor rather than 4.

3 / 5

Distinctiveness Conflict Risk

The changelog/release-notes-from-git niche is mostly distinct with minor overlap risk against general git or PR-review skills; not a 5 because the absence of explicit triggers leaves some conflict risk.
