Conciseness

The body is dense and assumes Claude's competence — no concept explanations, just operational facts like "Publishing is sequential, so the packages after it were skipped, not broken". However, the 2-day trust-expiry window is stated three times (step 4, the example dialogue, and the workflow-change section) and the example block partially restates steps 1–4, so minor trimming is possible. Fits the 4 anchor ("efficient; minor instances that could be trimmed") rather than 5 ("every token earns its place").

Actionability

Fully executable, copy-paste-ready commands throughout: `pnpm npm-trust preflight`, `pnpm npm-trust add <name>`, `pnpm npm-trust verify --package <name>`, `gh workflow run release.yml --ref main -f tag=<tag>`, `gh run view <run-id> --log-failed`, exact manifest JSON fields, and the tag regex `^[a-z][a-z0-9-]*$`. Failure classification maps each error signature to a specific recovery action. Matches the 5 anchor ("copy-paste ready code or commands; specific examples cover the common cases").

Workflow Clarity

Each scenario is a clearly sequenced workflow with explicit validation checkpoints and feedback loops: new-package flow runs preflight (expected "not on npm yet" failure documented), mandates the maintainer action with timing, and verifies after release; the diagnosis flow identifies the first failing package, classifies the cause, gives a per-class recovery command, and re-runs verify before concluding ("Re-run `verify` before concluding that something is missing"). Registry-mutating commands are gated behind explicit user confirmation, so the destructive-operation validation cap does not apply. Matches the 5 anchor (explicit validation steps; feedback loops for error recovery).

Progressive Disclosure

With no bundle files, the single SKILL.md acts as a well-sectioned overview that delegates depth one level deep with clearly signaled references: "The full runbook is `contributing/npm-publishing.md`; the decision record is `docs/adr/0002-npm-trusted-publishing.md`. Read the runbook section that matches the request instead of restating it", plus targeted pointers for changesets and monorepo structure. Sections (When to use / not, Required inputs, per-scenario Instructions, Expected output, Safety) make navigation trivial. Matches the 5 anchor (clear overview, well-signaled one-level-deep references) rather than 4 because no inlined content belongs in a separate file.

Specificity

"Guides npm publishing for Fusion Framework packages through trusted publishing (OIDC) from release.yml" names the domain and mechanism, then lists multiple concrete actions: "adding a new public package, preparing a first release, reserving a package name on npm, snapshot or pre-release publishing, diagnosing failed or partial npm releases (ENEEDAUTH, 401, 404, provenance), npm trust audit/bootstrap/verify, changing the release workflow" — comprehensive coverage with no vague filler. It is above the 4 anchor ("several specific actions; minor gaps") because coverage spans the skill's full scope, not a subset.

Completeness

Both questions are answered explicitly and concretely: what — "Guides npm publishing for Fusion Framework packages through trusted publishing (OIDC) from release.yml"; when — an explicit "USE FOR:" clause enumerating trigger scenarios plus a "DO NOT USE FOR:" clause for exclusions. This matches the 5 anchor ("clearly and explicitly answers both what AND when with concrete trigger phrases") and exceeds the 4 anchor where "when could be more explicit".

Trigger Term Quality

Natural user phrasings are comprehensively covered: "npm publishing", "release", "adding a new public package", "reserving a package name", "snapshot or pre-release publishing", "failed or partial npm releases", plus pasted error codes ("ENEEDAUTH, 401, 404, provenance") users would literally quote, and exclusion terms ("changesets", "Dependabot PRs", "VS Code Marketplace"). Fits the 5 anchor (comprehensive natural terms incl. synonyms) rather than 4 ("a few natural terms missing") — no common trigger phrasing for this domain is absent.

Distinctiveness Conflict Risk

A clear niche is staked out ("Fusion Framework packages", "trusted publishing (OIDC) from release.yml") with minimal conflict risk, and the DO-NOT-USE list actively disambiguates adjacent skills ("writing changesets, Dependabot PRs, VS Code Marketplace publishing, rebasing Version Packages PRs"). Distinct from the 4 anchor ("minor overlap risk with closely related skills") because overlap candidates are explicitly excluded rather than merely unlikely.
