Conciseness

The body is lean and dense with actionable specifics (audience size bands, form-field conversion rates, tool names) with no explanation of concepts Claude already knows; the single framing sentence about LinkedIn CPM cost earns its place by justifying the targeting rules.

Actionability

Concrete tool names (list_audiences, pull_linkedin_ads_performance, list_campaigns) and specific numeric guidance (50k/300k/500k thresholds, 12-15% conversion bands) make the guidance mostly executable, but tool invocations lack arguments or syntax and a few directives ("map your vertical to LinkedIn's taxonomy") are directional rather than concrete.

Workflow Clarity

Sections 1-5 give a clear build-to-verify sequence with a "Verify and iterate" section and pre-launch checks in Rules ("Check estimated audience size before launch; fix anything under 50k"), but some checkpoints are implicit or distributed rather than embedded as explicit validation steps in the flow, so it falls short of the feedback-loop-rich top anchor.

Progressive Disclosure

A compact single-file skill (~55 lines) with well-organized numbered sections and clearly bold-signaled cross-skill references (**audience**, **attribution**, **media-plan**); all content appropriately lives in SKILL.md with no bundle files needed, qualifying for the simple-skill exception.

Specificity

"Build LinkedIn Ads audiences with job title, seniority, and company targeting, ABM company lists, lookalikes, and lead gen form optimization" lists multiple concrete capabilities that comprehensively cover the skill's scope, matching the top anchor rather than the 'minor gaps' anchor below it.

Completeness

The first sentence explicitly states what the skill does and the "Use when..." clause gives concrete trigger phrases, clearly matching the anchor requiring both what and when; it is well above the anchor where 'when' is only weakly implied.

Trigger Term Quality

"building LinkedIn audiences, setting up ABM, choosing ad formats, optimizing lead gen forms, or estimating LinkedIn costs" provides good natural-term coverage a user would actually say, but common synonyms such as "account-based marketing", "LinkedIn campaigns", or "B2B ads" are absent, keeping it below the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

The description is firmly niche (LinkedIn Ads targeting, ABM, lead gen forms) with distinct triggers, so it is unlikely to fire for unrelated skills and matches the minimal-conflict-risk anchor.
