Conciseness

The body is dense and largely assumes Claude's competence (no basic-concept padding), but it carries redundancy — the intro restates the description and the "Quality bar" checklist restates the "Done when" criteria, and the competitive-research paragraph could be tightened. It is mostly efficient rather than lean, so it sits at score 2 not 3.

Actionability

The numbered steps give concrete, specific guidance — "extract the page's headline, primary value prop, the concrete offer/claim, and the CTA", "build 3+ distinct angles (e.g. benefit, pain, proof, urgency)" — with named scripts (registry-events.py), memory offsets, and reference files. As an instruction-only skill the absence of executable code is not penalized because the guidance is actionable and copy-applicable, reaching the score-3 anchor.

Workflow Clarity

An explicit 8-step sequence with embedded validation checkpoints (step 6 drop unmatched units, step 7 flag claims/policy), a "Quality bar before handoff" checklist, and a fix-or-report feedback loop ("If any item fails, fix it or report it in the handoff — do not ship silently"). This matches the score-3 anchor of clear sequence with explicit validation and error-recovery; it is above 2 because checkpoints are explicit rather than implicit, and batch-creative validation is present so the cap does not apply.

Progressive Disclosure

The body is an overview that offloads detail to one-level-deep, clearly signaled references — local bundle files references/ad-format-specs.md and references/angle-matrix.md (both present on disk) plus a dedicated Reference Materials section — matching the score-3 anchor of well-signaled, shallow references rather than a monolithic wall or nested chain.

Specificity

Lists multiple concrete actions — "produces ad units — RSA headlines/descriptions, hooks, and an angle matrix — message-matched to the destination landing page" — matching the score-3 anchor that names several specific actions rather than vague language.

Completeness

Explicitly answers both what (produces RSA headlines/descriptions, hooks, angle matrix, message-matched) and when via a clear "Use when the user asks to..." clause, satisfying the highest anchor; it is not missing the when clause that would cap it at 2.

Trigger Term Quality

Embeds natural user phrasings as triggers — "write ad copy", "generate RSA headlines", "build ad creative at volume" — giving good coverage of terms a user would actually say, beyond technical jargon.

Distinctiveness Conflict Risk

Explicitly fences off sibling skills — "Not for scoring an ad account — use ad-account-auditor; not for the post-click page — use landing-optimizer; not for organic articles — use content-writer" — establishing a clear niche unlikely to trigger the wrong skill.
