Conciseness

The body is a lean 31-line checklist plus a two-sentence boundary section; every line is a check or command and nothing explains concepts Claude already knows. This matches anchor 5 (lean and efficient, every token earns its place) and clearly exceeds anchor 4, which still allows trimmable over-explanation.

Actionability

Most guidance is concretely executable: explicit file paths (e.g., `.claude/commands/<slug>.md`, `scripts/install.sh`) and copy-pasteable commands like `bash "$ENGINE/scripts/verify-generated-package.sh" "$PACKAGE_ROOT"`. It stops short of anchor 5 because the commands depend on resolving `ENGINE` via `/hep-build` Step 0 and on external scripts that are not bundled or recoverable within this skill, leaving a gap if that dependency is unavailable.

Workflow Clarity

Explicit validation checkpoints are present (three verify/safety script invocations), satisfying the validation requirement for batch/release operations, and the checklist is roughly ordered (structure checks, then ENGINE resolution, then verification). It does not reach anchor 5 because the list is unnumbered with only implicit ordering (PACKAGE_ROOT must exist before the verify commands) and there is no feedback loop describing what to do when a check fails.

Progressive Disclosure

The skill is under 50 lines, single-purpose, and needs no external references; it is organized into two well-labeled sections (Checklist, Public Boundary), matching the rubric's exception for short simple skills. All paths referenced point to the generated package or engine repository rather than to missing bundle files, so navigation is unambiguous.

Specificity

The description names one action ("packaging this meta-agent") and a set of concrete target scenarios ("public Codex plugin registration, Claude Code installation, GitHub release, one-line terminal install, or open-source distribution") but does not enumerate the specific actions the skill performs (verification, checklist enforcement, publishing boundary). This matches anchor 3 (domain plus 1-2 concrete actions, not comprehensive) rather than 4, which expects several distinct listed actions.

Completeness

Both parts are present: the 'when' is explicit and specific ("Use when packaging this meta-agent for...") and the 'what' is stated as packaging for registration, installation, and release. It does not reach 5 because the 'what' leans on scenario enumeration rather than stating the concrete operations the skill carries out, keeping the 'what' side thinner than the 'when' side.

Trigger Term Quality

Natural user phrases are present ("packaging", "GitHub release", "one-line terminal install", "open-source distribution", "Codex plugin registration"), giving good keyword coverage. It falls short of anchor 5 because common synonyms such as "publish" and extension/tool names beyond 'Codex plugin' are missing, and the term "meta-agent" is project jargon rather than something a user would naturally say.

Distinctiveness Conflict Risk

It carves out a clear niche (packaging this specific meta-agent for public distribution across named platforms) with distinct trigger phrases unlikely to fire for unrelated skills. Anchor 5 fits; there is no meaningful overlap with generic packaging or publishing skills given the specific platform names.
