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 Opportunity Solution Tree to structure product discovery — map a desired outcome to opportunities, solutions, and experiments') and when ('Use when structuring discovery work, mapping opportunities to solutions, or deciding what to build next') with an explicit 'Use when' clause.

Includes strong natural keywords users would say: 'Opportunity Solution Tree', 'OST', 'product discovery', 'opportunities', 'solutions', 'experiments', 'deciding what to build next', 'Continuous Discovery Habits', 'Teresa Torres'. These cover both the framework name and the natural language a user might use.

Highly distinctive due to the specific framework reference (Opportunity Solution Tree, Teresa Torres, Continuous Discovery Habits). This is a clear niche that is unlikely to conflict with other skills — it targets a very specific product discovery methodology.

Significant verbosity explaining concepts Claude already knows well — what an OST is, who Teresa Torres is, what the Product Trio is, what opportunities vs features means. The 'Domain Context' section is essentially a textbook summary that doesn't add actionable value. Quotes like 'Best ideas often come from engineers' and extensive principle explanations are padding.

The 6-step process provides a reasonable framework, and the Opportunity Score formula is concrete. However, there's no executable output format, no template or example of a completed OST, no sample markdown structure to produce. The instruction 'Think step by step. Save as markdown if substantial.' is vague. The experiment design step mentions specifying hypothesis/method/metric/threshold but gives no example.

The 6 steps are clearly sequenced and logically ordered. However, there are no validation checkpoints — no guidance on when to loop back, how to verify opportunity framing is correct, or what constitutes a well-formed tree before proceeding. The 'Discovery is not linear' principle mentions looping back but doesn't integrate this into the workflow steps.

The content has some structure with sections (Domain Context, Instructions, Process, Further Reading), but the Domain Context section is a large inline block that could be separated or significantly trimmed. The Further Reading links are external URLs rather than bundle files, and there are no supporting reference files. For a standalone skill with no bundle, the organization is adequate but the inline domain context bloats the main file.
