Conciseness

The body is lean and imperative throughout — no concept explanations, no padding, and every bullet carries project-specific information Claude cannot infer (file globs, schema/build paths, workspace-scoped commands). 'Keep runtime behavior unchanged unless the task explicitly requires more than deprecation signaling' is a terse, high-value constraint.

Actionability

Mostly executable: exact file patterns, the literal metadata value "status": "deprecated", and copy-paste commands like 'npx prettier --write <paths>' and 'npm run build:hooks.json -w @primer/react'. Minor gaps keep it below 5: no example changeset content for the versioning step, no example @deprecated JSDoc annotation, and 'Run targeted tests for the affected API when available' gives no command.

Workflow Clarity

The sequence is clear (source → docs metadata → docs content → changeset → validation) and the Validation section is an explicit checkpoint tiered as 'Prefer targeted validation first, then broader validation if needed', including rebuild commands for schema-affecting changes. It falls short of 5 only because there is no explicit feedback loop (what to do when lint/tests fail) and steps are sectioned rather than sequenced with ordering cues.

Progressive Disclosure

This is a compact (~55-line) single-file skill with no bundle files and no content that warrants splitting; sections are well-organized and the pointers it does give ('contributor-docs/deprecating-components.md', 'contributor-docs/versioning.md') are one level deep, clearly named, and appropriately load-bearing rather than buried.

Specificity

The description enumerates concrete coverage areas — 'source annotations, docs metadata, changesets, docs page updates, and validation for deprecations' — which is broad and well-targeted, but these are area names rather than executed actions (e.g., 'add @deprecated JSDoc tags', 'set status: deprecated in docs JSON'), leaving minor gaps versus a fully comprehensive 5.

Completeness

It explicitly answers both questions: what it does ('Covers source annotations, docs metadata, changesets, docs page updates, and validation for deprecations') and when to use it ('Use when: deprecating Primer React components or hooks'), with concrete, specific trigger phrases — matching the anchor-5 pattern rather than anchor 4, where the 'when' would be less specific.

Trigger Term Quality

'deprecating Primer React components or hooks' supplies the natural phrases a contributor would use (deprecate, component, hook, Primer React), but it omits common variations like 'deprecation', 'sunsetting', 'removing', or '@deprecated' that a user might naturally say.

Distinctiveness Conflict Risk

'Primer React components or hooks' carves out a clear niche with distinct triggers; no other plausible skill would be invoked by this description, so conflict risk is minimal.
