Conciseness

The body is dense with facts — nearly every line carries a benchmark, formula, or decision rule (e.g. 'max customers = new customers per month ÷ monthly logo churn', 'organic 40-50%, paid under 50%') and there is no padding explaining concepts Claude already knows. It is not 5 because the 'Receipts' section duplicates content in references/quotes.md and the heavy per-claim name attribution could be trimmed in places.

Actionability

For an instruction-only skill the guidance is fully executable: exact formulas ('net growth = new users − stale users + resurrected users'), reference thresholds ('Facebook 7 friends in 10 days; Slack 3 real people and 50 real messages'), pass/fail guardrails ('abandon or continue on those numbers'), a fill-in-the-blank deliverable template, and a 1/3/5-anchored grading rubric. Specific examples cover the common cases, matching the top anchor.

Workflow Clarity

The sequence is explicit — Step 1 diagnose (max 4 questions, 'State your inferred answers back in one line'), Step 2 pick the play via a situation table, Step 3 run it — with a hard validation gate ('if no flattening, stop and fix the product or run pmf-check') and 'Done when' checkpoints closing every play. Feedback loops and checklists are present, matching the top anchor; anchor 4 is surpassed because validation is explicit at each stage, not just at the end.

Progressive Disclosure

References are one level deep, real, and clearly signaled ('references/frameworks.md — every framework in this skill, how to run it'; 'references/quotes.md — verified quotes with timestamps'), and related-skill handoffs are listed. It is not 5 because some content that could live in references is inlined — the six 'Receipts' quotes duplicate references/quotes.md and the full 8-criterion grading table is a self-contained artifact that could be split out — leaving minor organization gaps that match anchor 4.

Specificity

The description lists multiple concrete actions — 'Diagnose where your growth is actually leaking (acquisition, activation, retention, or loops)' and 'produce a growth plan with a named loop, an activation definition, a 90-day experiment portfolio and channel guardrails' — comprehensively covering the skill's scope with no vague filler. It fits the top anchor better than 4 because the action list spans the skill's full output rather than having coverage gaps.

Completeness

It explicitly answers 'what' (diagnose the leak, produce a growth plan with four named components) and 'when' ('Use it when someone says...') with concrete trigger phrases. Both halves are explicit and concrete, matching the top anchor exactly.

Trigger Term Quality

It includes nine natural user phrasings in question and statement form: 'growth stalled', 'signups don't activate', 'retention is flat', 'how do we build a growth loop', 'should we go PLG', 'onboarding redesign', 'churn', 'referral program', 'which channel should we bet on'. These cover synonyms and colloquial variations a user would actually say, matching the comprehensive-coverage anchor; nothing common is missing.

Distinctiveness Conflict Risk

The growth-diagnosis niche is clear and most triggers ('should we go PLG', 'how do we build a growth loop') are distinct, but terms like 'churn', 'onboarding redesign' and 'retention is flat' could also route to narrower retention or onboarding skills in the same family (pmf-check, metrics, position). Minor overlap risk with closely related skills matches anchor 4; it is not 5 because a few triggers are shared vocabulary with adjacent domains.
