Conciseness

The body is dense decision rules with short, load-bearing examples; it never explains concepts Claude already knows and assumes competence ("No phrasing is banned; nothing survives on phrasing either"). Every section — the bar, renames, openers, log comments, tests, JSDoc, changelogs, PR bodies, checklist — earns its place.

Actionability

Concrete, executable guidance throughout: named lint rules to check ("ocap/require-jsdoc", "jsdoc/require-param-description", "oxlint.config.ts"), specific opener phrases to inspect ("Ensure", "Handle", "Note that", "Important"), keep/delete code examples for each artifact type, and a 6-step checklist. For an instruction-only skill this fully covers the common cases.

Workflow Clarity

The final Checklist gives a clear ordered sequence (judge → delete → consider rename + re-run lint → re-read survivors → apply to changelogs/PR bodies → return control) with an explicit validation step ("re-run lint", "verify the result still lints") and a review loop (step 4, "this is the pass that gets skipped"). The batch-deletion nature of the pass is covered by lint validation and the JSDoc lint-required carve-out.

Progressive Disclosure

Well-organized single file with clear section headers and one clearly signaled, one-level-deep reference ([docs/contributing/updating-changelogs.md] for format and categories, with the section explicitly scoped to length only). Not 5 because everything lives in one ~178-line SKILL.md with no overview/reference split, which fits anchor 4's 'good structure; minor organization gaps' rather than anchor 5's 'content appropriately split'.

Specificity

Names four concrete artifacts ("added comments, JSDoc, changelog entries, and PR bodies") and two specific actions ("judge... on information content", "cut what a reader can derive"), matching anchor 4's 'several specific actions; minor gaps'. Not 5 because the verbs are somewhat abstract and don't enumerate the per-artifact judgments the body actually contains.

Completeness

Explicitly answers both: what ("Judge added comments, JSDoc, changelog entries, and PR bodies on information content and cut what a reader can derive") and when ("Use before presenting a diff, committing, or writing a PR body") with three concrete trigger conditions, matching the anchor-5 example pattern.

Trigger Term Quality

Includes natural phrases users and workflows would say — "comments", "JSDoc", "changelog entries", "PR bodies", "diff", "committing" — giving good keyword coverage. Not 5 because synonyms and variations (e.g. "release notes", "docstrings", "documentation comments") are missing.

Distinctiveness Conflict Risk

Has a clear niche — information-content judgment of prose in a diff — that is distinguishable from logic-review skills. Not 5 because the timing triggers "before presenting a diff" and "committing" carry minor overlap risk with closely related commit-message and code-review skills.
