Conciseness

The body is dense with practitioner heuristics (specific splits, thresholds, caps) rather than explanations of concepts Claude already knows, but contains minor rhetorical padding that could be trimmed — the motivational opening ('does not light money on fire', the $100K/$2.5M framing) and the three-paragraph closing section. This fits 'efficient; minor instances of over-explanation that could be trimmed' rather than the noticeably-verbose level 3.

Actionability

As an instruction-only skill the guidance is fully concrete: a worked hypothesis example with real figures ('Increasing Search budget from $40K to $80K per month should hold CAC under $80'), numeric thresholds throughout (70-30 to 80-20 splits, 30+ conversions before tCPA, frequency caps of 3-4 per week for Awareness), a 7-item negative-spend audit list, and 12 failure patterns each with a fix. Specific examples cover the common cases.

Workflow Clarity

The numbered 11-consideration framework is an explicit checklist ending in a defined three-answer output (Scale, Hold, Kill), pre-committed falsification thresholds act as validation checkpoints, and destructive decisions are protected by feedback loops ('test with hold-out, not flat off', pull-back rules at known CAC thresholds).

Progressive Disclosure

Each section gives the short version and clearly signals one-level-deep references ('Detail in [references/common-failures.md]'), all 7 referenced files exist in the bundle with no nested references, and a closing 'Reference files' index lists each with a one-line description, making navigation easy.

Specificity

The description lists multiple concrete capability areas — 'Hypothesis writing for paid spend, channel selection, budget allocation, audience targeting, bid strategy, campaign types, what NOT to spend on, attribution reality, and the failure modes' — in third-person voice, comprehensively covering the paid media strategy lifecycle with no notable gaps.

Completeness

Both 'what' and 'when' are explicit: the capability list states what the skill does, and 'Triggers on...' plus 'Also triggers when a team is asking how to scale paid media, or whether to add a new channel, or how to reallocate spend across channels' provides explicit trigger guidance with concrete phrases.

Trigger Term Quality

Trigger terms cover natural user phrasings comprehensively with synonyms and platform-specific variants: 'paid media strategy, ad budget allocation, paid media plan, audit my Google Ads, audit my Meta Ads, scale paid media, kill underperforming campaign, paid media hypothesis, ad spend strategy, performance marketing strategy', plus scenario phrasings like 'how to scale paid media' and 'how to reallocate spend across channels'.

Distinctiveness Conflict Risk

The paid media / performance marketing niche is clear and most triggers are unmistakably paid-specific ('audit my Google Ads', 'kill underperforming campaign'), but bare generic terms like 'channel selection' and 'attribution reality' could fire for closely related marketing or analytics skills, creating minor overlap risk.
