Conciseness

Roughly 30 lean lines with no padding or explanation of concepts Claude already knows; the npm inclusion rules (files field precedence, always-included README/LICENSE/CHANGELOG) are non-obvious specifics that earn their tokens. Not 4 because no over-explanation was found to trim.

Actionability

Provides a concrete copy-paste command ('bash scripts/list-package-files.sh') backed by a real, complete script, and summarizes its behavior accurately. Not 5 because 'Run the script from the package directory (e.g., packages/ai)' leaves ambiguous whether the relative path resolves from the package directory or the skill directory, and the pnpm-vs-npm tooling assumption is unstated.

Workflow Clarity

A single-action skill whose one step is unambiguous: run the script, which builds, packs, lists, and cleans up (matching the actual script). The rm only removes the tarball the script itself created, so the destructive-operation cap does not apply.

Progressive Disclosure

Under 50 lines with well-organized sections (Usage, Understanding Package Contents) and one real, one-level-deep script reference that exists in the bundle. No external references are needed for a skill this size.

Specificity

Names the domain ('npm package tarball') and one concrete action ('List the contents... before publishing'), but offers no additional capabilities such as inspecting sizes or diffing against the files allowlist. It is not 4 because only a single action is listed, and not 2 because the action and domain are concrete rather than generic.

Completeness

Explicitly answers both what ('List the contents of an npm package tarball before publishing') and when ('Use when the user wants to see what files are included in an npm bundle, verify package contents, or debug npm publish issues') with concrete trigger phrases, matching the anchor 5 example structure.

Trigger Term Quality

Includes several natural phrases users would say ('npm bundle', 'verify package contents', 'debug npm publish issues'). It is not 5 because common variants like '.tgz' or 'what's in my package' are missing, and not 3 because coverage goes beyond a couple of generic keywords.

Distinctiveness Conflict Risk

Occupies a clear niche (pre-publish npm tarball inspection) with distinct triggers ('npm bundle', 'npm publish issues') and minimal overlap with generic packaging or publishing skills.
