Lists multiple specific concrete actions: 'Build an Opportunity Solution Tree', 'map a desired outcome to opportunities, solutions, and experiments', and 'structuring discovery work'. It also names the specific framework (Teresa Torres' Continuous Discovery Habits).

Clearly answers both 'what' (build an OST to structure product discovery, map outcomes to opportunities/solutions/experiments) and 'when' (explicit 'Use when structuring discovery work, mapping opportunities to solutions, or deciding what to build next').

Includes strong natural keywords users would say: 'Opportunity Solution Tree', 'OST', 'product discovery', 'opportunities', 'solutions', 'experiments', 'what to build next', 'discovery work'. These cover both the formal framework name and natural language variations.

Highly distinctive — references a specific framework (Opportunity Solution Tree / Teresa Torres) and a clear niche (product discovery structuring). Unlikely to conflict with generic product management or roadmapping skills due to the specific methodology named.

The domain context section explains concepts like what an OST is, its structure, and key principles at length. While some of this is useful framing, much of it (e.g., explaining what opportunities vs features are, quoting principles Claude could infer) is verbose. The quotes and attributions add tokens without adding actionability.

The process steps provide a reasonable sequence but remain at a high level of abstraction — there are no concrete examples of a completed OST, no template markdown output, no sample experiment format. The Opportunity Score formula is a nice concrete detail, but overall the skill describes what to do rather than showing executable examples of the output.

The 6-step process is clearly sequenced and logical, but lacks validation checkpoints or feedback loops. Step 4 mentions 'most promising solutions' without criteria for selection, and there's no explicit guidance on what to do when experiments fail beyond a brief mention in the principles section. For a multi-step discovery process, explicit checkpoints would strengthen this.

The Further Reading section provides external references, but the skill itself is monolithic — the lengthy domain context, principles, and process are all inline. The domain context section could be separated or significantly trimmed. The external links are to web articles rather than companion skill files, limiting their utility in a skill context.
