Quality

Content

92%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.

An exemplary single-file skill: concrete git and gh commands, a well-sequenced procedure with an evidence-priority fallback chain, early-stop condition, verification step, and completion checklist. The only flaw is slight redundancy between the Defaults section and later procedure steps.

DimensionReasoningScore

Conciseness

The body is lean, assumes Claude's competence, and never explains known concepts; commands appear as bare copy-paste blocks. It sits at 4 rather than 5 because of minor trimmable redundancy: the Defaults section ("Keep the wording brief", "Skip Features/Improvements/Bug Fixes headings") restates guidance that Steps 5-6 and Completion Checks also carry, and "When to Use" repeats the frontmatter description.

4 / 5

Actionability

Fully executable guidance: concrete commands like `GH_PAGER=cat gh release view v<version> --repo <owner>/<repo> --json tagName,name,publishedAt,body`, `git log -1 --format=%cs v<version>`, and `git --no-pager diff --stat v<previous>..v<version>` are copy-paste ready, and the include/exclude lists in Step 4 give concrete selection criteria. This matches the 'fully executable; specific examples cover the common cases' anchor.

5 / 5

Workflow Clarity

A clear 7-step sequence with explicit validation: an early stop condition ("If the latest version is already documented, stop and report"), an ordered evidence-source fallback chain (GitHub release -> tag date -> commit history -> diff), a Verify step ("Check dates, version numbers, and tag boundaries"), and a Completion Checks checklist. This is not a destructive or batch operation, so the workflow-clarity cap does not apply, and the fallback chain plus verify/checklist steps match the top anchor rather than the 'minor validation gaps' 4 anchor.

5 / 5

Progressive Disclosure

No bundle files exist and the body references none; all guidance (about 105 lines) is appropriately inline for a single-purpose skill, organized under well-labeled sections (Defaults, numbered Procedure, Completion Checks) that make navigation trivial. Nothing that belongs in a separate file is inlined, so it cannot be penalized under the structure anchors and fits the well-organized, easy-to-navigate top anchor.

Description

83%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.

A strong description: concrete artifact, named evidence sources, and an explicit third-person 'Use when' clause with natural trigger phrases. Its only weakness is that the what compresses to a single action and 'release notes' slightly overlaps a neighboring skill domain.

DimensionReasoningScore

Specificity

"Update docs/CHANGELOG.md from git history, GitHub releases, and code diffs" names a concrete artifact and three specific evidence sources, matching the 'several specific actions; minor gaps' anchor. It is not a 5 because the what is essentially a single action (update one file) rather than a list of multiple distinct capabilities.

4 / 5

Completeness

The what is explicit ("Update docs/CHANGELOG.md from git history, GitHub releases, and code diffs") and the when is explicit with concrete trigger phrases ("Use when: writing release notes, syncing the latest changelog entry, summarizing a new tag, or keeping changelog wording concise and consistent"), in third person voice. This matches the top anchor answering both what and when with concrete triggers; not a 4 because the when clause is neither vague nor merely implicit.

5 / 5

Trigger Term Quality

Natural phrases users would say are present: "writing release notes", "syncing the latest changelog entry", "summarizing a new tag", "changelog wording concise and consistent". A few common variations (e.g. "what's changed", "version history") are missing, so it fits the 'good keyword coverage; a few natural terms missing' anchor rather than comprehensive coverage.

4 / 5

Distinctiveness Conflict Risk

"CHANGELOG.md", "GitHub releases", and "summarizing a new tag" define a clear niche with low conflict risk, but "writing release notes" could overlap with a dedicated release-notes-drafting skill, matching 'mostly distinct; minor overlap risk with closely related skills' rather than the minimal-conflict 5 anchor.
