Conciseness

The body is dense and information-rich: nearly every section carries domain facts Claude would not know (the two published bands, the 70% concentration thresholds, percentile-bucket interpretation, add-back rules). A few passages are discursive and could be trimmed — the buyer organic/paid preference aside ('cited preferences run from 100% organic through 50/50 to 75/25 paid/organic') and some of the deal-structure detail — so it matches 'Efficient; minor instances of over-explanation' rather than the every-token-earns-its-place anchor.

Actionability

For an instruction-only skill the guidance is fully executable: exact tool invocations ('Request proceeds from `get-chart-data` on the `revenue` chart with the `revenue_type` selector set to `proceeds`', 'Use `get-benchmarks`' `percentile_bucket` directly: 70+ is strong, 30–70 neutral'), numeric thresholds throughout, a fully worked arithmetic example ('$200k ARR × 60% assumed margin = $120k profit × 3–5x'), and a mandated output format (named base × multiples, position, confidence).

Workflow Clarity

The method is explicitly sequenced — 'A valuation is four decisions, in order' — with each step numbered, decision gates ('Fail any check and the broad-market band applies. Say which check failed'), divergence triggers ('when it differs... by more than about 20%, present both'), and a required closing step stating the range, confidence, and what would move it. Validation checkpoints are built into the flow rather than left implicit.

Progressive Disclosure

There are no bundle files (references/, scripts/, assets/ are absent) and the ~280-line body is monolithic: the valuation core, the scorecard detail, the 'Preparing to sell, finding buyers, negotiating' section, and the citing-sources section are all inlined in one file. Structure is good at the section level, but content that would serve better as separate reference files (sale prep, sourcing/citation policy) is inline, matching 'Some structure but could be better organized' — the under-50-line single-file exception does not apply at this length.

Specificity

The description names the domain ('app valuations', 'sale/exit', 'subscription app') but lists no concrete actions — it is purely a list of trigger situations with no verbs describing what the skill actually does. It matches 'Names the domain but actions are minimal or generic'; not score 3 because no 1-2 concrete actions are stated, and not score 1 because the language is concrete rather than abstract.

Completeness

The 'when' is explicit and strong, but the 'what' is never stated — the skill's capabilities (estimate a profit-multiple range, score factors, ground it in RevenueCat data) are only implied through the trigger topics. It sits between 'only when present without what' (2) and 'both present' (4): the trigger list conveys a moderately clear what, but no capability is explicitly declared.

Trigger Term Quality

It covers the natural phrases a user would actually say for this need — 'how much their app is worth', 'what they could sell their app for', 'app valuations', 'acquisitions', 'prepare a subscription app for sale/exit' — including the synonyms (sell/sale/exit, worth/valuations). Matches the comprehensive-coverage anchor rather than the 'a few natural terms missing' anchor.

Distinctiveness Conflict Risk

It carves a clear niche — valuing and selling a (subscription) app — with triggers ('how much is my app worth', 'sell my app', 'valuation', 'acquisition', 'exit') unlikely to fire for any other skill. Clear niche with distinct triggers; minimal conflict risk.
