Lists multiple specific concrete actions: hypothesis writing, channel selection, budget allocation, audience targeting, bid strategy, campaign types, what NOT to spend on, attribution reality, and failure modes. These are clearly defined capabilities.

Clearly answers both 'what' (hypothesis writing, channel selection, budget allocation, audience targeting, bid strategy, etc.) and 'when' with explicit trigger terms and scenario-based triggers ('when a team is asking how to scale paid media, or whether to add a new channel, or how to reallocate spend').

Excellent coverage of natural terms users would say: 'audit my Google Ads', 'audit my Meta Ads', 'scale paid media', 'kill underperforming campaign', 'ad spend strategy', 'attribution reality', 'performance marketing strategy'. These are highly natural phrases a user would actually type.

Occupies a clear niche around paid media strategy and ad spend. The specific mentions of Google Ads, Meta Ads, bid strategy, and attribution make it highly distinct from general marketing or content strategy skills.

The skill is well-written and mostly efficient, but it's quite long (~400 lines) with some sections that over-explain concepts a senior performance marketer (or Claude) would already know. The introductory paragraphs, the 'What this skill is for' section, and the closing section add context that doesn't directly instruct. Some channel descriptions repeat common knowledge. However, the content is not egregiously padded—most sections carry useful, opinionated guidance.

The skill provides strong strategic guidance with specific numbers (e.g., '30+ conversions for tCPA', 'frequency above 4', '70-30 to 80-20 splits') and concrete decision rules, which is good. However, it lacks executable artifacts—no code, no command examples, no templates inline, no audit checklists with checkboxes, no example spreadsheet structures. For a strategy skill this is partially acceptable, but the guidance remains at the 'informed advice' level rather than 'copy-paste ready' operational level. The hypothesis example is excellent and concrete, but most other sections describe what to do rather than providing ready-to-use frameworks.

The 11-consideration framework provides a clear sequence, and the scale/hold/kill decision output is well-defined. The hypothesis section includes pre-commitment and falsification rules, which serve as validation checkpoints. However, the skill lacks explicit step-by-step workflows for common operations like 'audit an existing account' or 'add a new channel'—these are described conceptually but not sequenced with validation gates. For a skill covering destructive budget decisions, the absence of explicit 'check X before proceeding to Y' patterns in the operational sections is a gap.

The skill has excellent progressive disclosure structure. The main body provides opinionated summaries for each topic, and seven clearly-labeled reference files are linked at relevant points throughout the text and collected in a dedicated reference section. References are one level deep, well-signaled with descriptive text, and the paths are consistent. The main file serves as a navigable overview that points to deeper detail appropriately.
