Conciseness

The body is lean (~30 lines) with no padding and no explanation of concepts Claude already knows; every line is direct instruction, matching 'Lean and efficient; assumes Claude's competence; every token earns its place.'

Actionability

A copy-paste-ready routing table maps concrete request types to specific `/notfair:...` commands, and the opening paragraph gives a concrete checklist of inputs to establish; for an instruction-only skill the guidance is fully actionable and covers common cases.

Workflow Clarity

There is a clear logical sequence (read shared docs -> establish business outcome/inputs -> route -> operating posture) with validation checkpoints ('published only after the platform confirms the exact object and settings', 'Establish that the platform's own verified connector is available before promising an account read or write'), but no explicit numbered checklist or error-recovery feedback loop, so it falls at score 4.

Progressive Disclosure

This under-50-line router is an overview with well-organized sections and clearly signaled one-level-deep references ('Read ../shared/operating-contract.md and ../shared/measurement-framework.md before acting') plus routing to specialized skills, meeting the simple-skill exception for a score of 5.

Specificity

The description names the paid-media domain and eight specific platforms but relies on a single abstract action verb ('Coordinate safe, evidence-based paid-media work'); it does not list several concrete operations (audit/operate/optimize/launch), which the score-4 anchor requires.

Completeness

It explicitly answers 'what' ('Coordinate safe, evidence-based paid-media work across [8 platforms]') and 'when' with concrete trigger phrases ('Use for broad ads questions, multi-channel strategy, budgets, CPA or ROAS, ...'), matching the score-5 anchor for both being clearly and explicitly present.

Trigger Term Quality

The 'Use for broad ads questions, multi-channel strategy, budgets, CPA or ROAS, campaign requests, spend, ad performance' clause supplies many natural phrases users would say, though a few common synonyms (e.g., 'PPC', 'paid social', 'ad accounts') are missing, keeping it just below comprehensive.

Distinctiveness Conflict Risk

The named-platform niche is clear and mostly distinct, but as a router that explicitly forwards to specialized sub-skills it carries minor overlap risk with those sub-skills on single-platform requests, which fits 'mostly distinct; minor overlap risk' rather than minimal.
