Conciseness

The body is dense and directive throughout with zero explanation of concepts Claude already knows — e.g. the evidence policy, mutation gate, and scoring rules are stated as bare operational contracts. It does not reach 5 because a few sections could be trimmed: the niche ads-cockpit companion paragraph, the Ten Thinking Principles glosses, and coverage thresholds (80%/60-79%/<60%) that duplicate references/scoring-system.md.

Actionability

For an instruction-only orchestration skill the guidance is fully executable: an exact command-to-skill routing table, a six-item mutation-gate checklist, canonical hard-stop request->response contracts (e.g. "Permanently delete every paused campaign." -> "refuse deletion and offer only reversible alternatives"), a copy-pasteable secret-reference JSON example, and explicit retry/partial-failure rules. Specific examples cover the common risky cases; it is not 4 because there are no material gaps in executability.

Workflow Clarity

A ten-step Operating order with explicit validation checkpoints at every risky surface — "Validate input completeness and source freshness before applying thresholds", "stop at a draft unless the mutation gate passes in full", "Verify produced artifacts and actions with tool results" — plus a Completion gate checklist and feedback loops (retry one transient failure, needs_input path, partial-bundle labeling). Destructive and batch operations are thoroughly validated, so neither the anchor-4 'minor validation gaps' nor the destructive-op cap applies.

Progressive Disclosure

A dedicated Progressive disclosure section lists eleven references with one-line purposes, every one of which exists in the bundle (thinking-framework.md, scoring-system.md, benchmarks.md, conversion-tracking.md, compliance.md, compliance-requirements.md, mcp-integration.md, additional-platforms.md, automation-tier-classifier.md, status-contract.md, prompt-patterns.md), all one level deep with load-only-when-needed rules and gap reporting for absent resources. It is not 4 because navigation is clear and content is appropriately split: SKILL.md carries only routing and safety policy while detail lives in references and per-command sub-skills.

Specificity

Lists nine concrete capability areas — "account intake, source-grounded audits, strategy, budget and measurement planning, creative production, experiments, reporting, monitoring, and explicitly approved campaign changes" — across twelve named platforms, giving comprehensive, action-level coverage of the paid-media lifecycle. It sits at the top anchor rather than 4 because coverage is comprehensive with no significant gaps, not merely 'several specific actions with minor gaps'.

Completeness

Explicitly answers both questions: the 'what' is "Operate professional paid advertising across Google, Meta, ..." with a concrete capability list, and the 'when' is stated twice with concrete trigger phrases ("Use for account intake, ..." and "Also trigger on PPC, paid social, ..."). This matches the top anchor exactly; it is not 4 because the 'when' clauses are explicit and specific rather than improvable.

Trigger Term Quality

Includes many natural user phrases and synonym pairs — "PPC, paid social, retail media, attribution, tracking, landing pages, ... negative keywords or search terms, ... API-token or credential setup" — plus all twelve platform names. It falls just short of the 5 anchor because a few natural terms users would actually say are missing, e.g. colloquial platform names like Facebook/Instagram ads and metric terms such as ROAS, CPA, or ad spend.

Distinctiveness Conflict Risk

Occupies a clear paid-advertising niche with distinctive triggers (PPC, negative keywords, cross-platform conversion totals, campaign deletion, Claude Ads install/uninstall) that are unlikely to fire for unrelated skills. Minimal conflict risk; not 4 because there is no meaningful overlap with neighboring skill domains.
