Conciseness

The body is lean and fully operational — "Resolve `ENGINE` using `/hep-build` Step 0", the three bash commands, and the file checklist — with no padding and no explanation of concepts Claude already knows; every token earns its place, matching anchor 5.

Actionability

The three bash commands (e.g., "bash \"$ENGINE/scripts/verify-generated-package.sh\" \"$PACKAGE_ROOT\"") are concrete and executable, but "inspect the generated package's selected adapters and install files" does not state what to inspect beyond file presence, and ENGINE resolution is delegated to an external skill — minor gaps that fit anchor 4 rather than the fully copy-paste-ready anchor 5.

Workflow Clarity

The sequence (resolve variables, run the three verification scripts, inspect files, apply the completion gate "Do not claim completion if any required file is missing") is clear with explicit validation scripts and a checkpoint, but no error-recovery loop is described for when a verification script fails, which anchor 5 requires.

Progressive Disclosure

This is a single-purpose skill well under 50 lines with no need for external reference files (no references/, scripts/, or assets/ directories exist in the bundle); the content is well organized with a heading, code block, and checklist, so it qualifies for the simple-skill exception scoring 5.

Specificity

"Verifies structure, adapters, schemas, executable scripts, and public-safety boundaries" lists several concrete verification targets, matching anchor 4's pattern of specific actions with minor gaps; it is not a 5 because coverage rests on a single verb over a list and "public-safety boundaries" remains abstract, and not a 3 because more than 1-2 concrete actions are named.

Completeness

It explicitly answers both questions: what ("Verifies structure, adapters, schemas, executable scripts, and public-safety boundaries") and when ("Use before claiming that the package can be installed or published"), an explicit and concrete trigger clause comparable to the anchor-5 commit-message example; it exceeds anchor 4, where the 'when' is only implied or under-specified.

Trigger Term Quality

The phrase "before claiming that the package can be installed or published" supplies natural keywords (install, publish, package) a user would actually say, but common variations and synonyms (release, check, build output) are missing, which fits anchor 4 rather than the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

The niche of verifying a generated agent package (adapters, schemas, public-safety checks) is mostly distinct with clear triggers, though "published" leaves minor overlap risk with generic publishing or release-verification skills, placing it at anchor 4 rather than the minimal-conflict anchor 5.
