Conciseness

The body is ~30 lines with zero padding: every checklist item is a concrete file path, variable assignment, or executable command, and the Public Boundary section is four terse rules. It assumes Claude's competence and every token earns its place, matching anchor 5 exactly; anchor 4's 'minor instances of over-explanation' do not exist here.

Actionability

Three fully executable verification commands with correct quoting and subshell usage ('bash "$ENGINE/scripts/verify-generated-package.sh" "$PACKAGE_ROOT"', '(cd "$PACKAGE_ROOT" && bash "$ENGINE/scripts/public_safety_check.sh")') and exact file paths for every artifact check. It falls short of anchor 5 because '<slug>' is never defined and ENGINE resolution is delegated to '/hep-build Step 0' rather than given inline — minor gaps that keep the guidance from being fully copy-paste ready.

Workflow Clarity

The checklist includes explicit validation checkpoints (three verify scripts that must 'pass') plus a safety check, but the sequence is only implicit: the prerequisite steps ('Resolve ENGINE using /hep-build Step 0 and set PACKAGE_ROOT') appear mid-list after the file-existence checks that depend on them, and there is no error-recovery loop for what to do when a verify script fails. Anchor 5 requires explicit validation AND feedback loops; anchor 4's 'clear sequence with most checkpoints, minor gaps' is the better fit.

Progressive Disclosure

The skill is under 50 lines with no bundle files and no need for external references; per the rubric's simple-skill guidance, well-organized sections alone qualify. The two sections (Checklist, Public Boundary) are cleanly separated and each item is self-contained, so navigation is trivial.

Specificity

The description names the domain ('packaging an Agentlas agent repo') and enumerates four concrete distribution targets ('public GitHub release, Codex plugin submission, Claude adapter distribution, or one-line terminal installation'), but the stated action is a single verb — packaging — with no breakdown of what packaging entails. It sits between anchor 3 (domain plus 1-2 concrete actions) and anchor 4 (several specific actions), and since the enumerated items are scenarios rather than distinct actions, 3 is the best fit.

Completeness

It explicitly answers both questions: what ('packaging an Agentlas agent repo') and when ('Use when packaging... for public GitHub release, Codex plugin submission, Claude adapter distribution, or one-line terminal installation'). The 'when' clause is fully explicit with four concrete trigger phrases, matching the anchor 5 example pattern; anchor 4 would require the 'when' to be less explicit than it is.

Trigger Term Quality

Natural trigger phrases are present and well-matched to the niche: 'packaging', 'public GitHub release', 'Codex plugin submission', 'Claude adapter', 'one-line terminal installation'. It falls short of anchor 5 because common synonyms and variations (e.g., 'publish', 'distribute', 'curl | bash install') are absent, though the coverage is clearly above the 'some relevant keywords' level of anchor 3.

Distinctiveness Conflict Risk

The 'Agentlas' qualifier plus the specific submission channels create a clear niche with distinct triggers and minimal overlap risk with generic packaging or publishing skills. Anchor 4's 'minor overlap risk with closely related skills' is a worse fit since the proper-noun domain makes confusion unlikely.
