Conciseness

The body is mostly lean and imperative with good wrong/correct examples, but section 3 restates the same 'relative to main, never the last commit' directive at least three times ('NEVER write a changeset relative to the last commit...', 'Use main / origin/main as the release baseline', 'Write changesets for the user-visible delta from the current main branch') plus overlapping bullet lists — 'mostly efficient but could be tightened'. It is above 2 because there is no conceptual padding or explanation of things Claude already knows, and below 4 because the repetition in Rule 3 goes beyond minor trimming.

Actionability

Fully copy-paste-ready: complete templates for simple, API-change, and breaking changesets; wrong/correct frontmatter YAML; concrete file-path examples ('.changeset/core-fix-types.md'); before/after code examples; and runnable registry commands ('node tooling/scripts/generate-ui-changelog-entries.mjs --write'). Not below 5 because the common cases are all concretely covered.

Workflow Clarity

For this single-purpose skill the action is unambiguous, and it includes an explicit pre-ship validation checklist ('## Red Flags: Before shipping') plus a verification requirement ('check whether any named removed/renamed API actually exists on main before writing removal or migration prose') — a genuine feedback loop. It meets the 5 anchor's 'checklists for complex processes' and the simple-skill exception.

Progressive Disclosure

The body is well-sectioned and appropriately delegates registry detail to the sibling 'registry-changelog' skill rather than duplicating its schema, and there are no bundle files to organize (references/, scripts/, assets/ are absent). It is 4 rather than 5 because the ~230-line body is self-contained where a reference file could carry the template gallery, and the Registry Changelog guidance is split across two sections (Rule 4 and the trailing '## Registry Changelog'), a minor organization gap.

Specificity

The description is 'Command: changeset' — it names the domain (changesets) but states zero concrete actions, matching the anchor 'names the domain but actions are minimal or generic'. It cannot score 3 because no action verbs or capabilities are listed at all, and it is above 1 only because 'changeset' is a concrete domain term rather than pure abstraction.

Completeness

It has an extremely vague 'what' (something about changesets) and no 'when'/usage guidance whatsoever, fitting 'has a vague what and no when'. It is not 1 because a specific domain is at least named, and it cannot be higher because neither the purpose nor any trigger conditions are explicit.

Trigger Term Quality

The only keyword is the bare word 'changeset' with no natural trigger phrases a user would say (e.g. 'write a changeset', 'release notes', 'version bump'), matching 'one or two generic keywords; missing the natural phrases users say'. It falls short of 3-4 because there are no synonyms, variations, or context terms at all.

Distinctiveness Conflict Risk

'Changeset' is a reasonably distinct niche term with limited conflict risk, but the description gives no scope boundaries, so it could overlap with adjacent skills (commit messages, PR descriptions, changelog generation) — 'somewhat specific but could still overlap with similar skills'. Not 4-5 because the description provides no distinguishing trigger phrasing to separate it from those neighbors.
