Conciseness

The ~400-line body duplicates the frontmatter intent verbatim in the Purpose section and repeats bias guidance in both the output template ("Biases to Avoid") and a standalone "Common Pitfalls" section, fitting 'mostly efficient but includes some unnecessary explanation'; it is not 4 because the redundancy exceeds minor over-explanation, and not 2 because most content is genuine domain-specific signal rather than padding.

Actionability

Copy-paste-ready question scripts ("Tell me about the last time you [experienced the problem]. What did you try?"), four enumerated options per question, and a fully worked Mom Test example match 'fully executable; copy-paste ready; specific examples cover the common cases'; it is not 4 because the worked example fills in every template placeholder for the primary use case.

Workflow Clarity

A clear Step 0 → Q1–Q4 → Output sequence with adaptation logic and a Success Criteria checklist matches 'clear sequence with most checkpoints present'; it is not 5 because there are no explicit validate-then-retry feedback loops, and not 3 because the steps are well-defined with adaptation guidance rather than gap-ridden.

Progressive Disclosure

Well-organized sections (Purpose, Input, Key Concepts, Application, Steps, Output, Examples, References) with clearly signaled one-level references to related skills (workshop-facilitation, problem-statement.md) match 'good structure; most content appropriately placed'; it is not 5 because a 400-line skill could offload the large output template or worked example into one-level-deep reference files for a leaner SKILL.md.

Specificity

Quotes "Plan customer discovery interviews with the right goal, segment, constraints, and method" name the domain plus four concrete planning dimensions, matching the 'several specific actions; minor gaps' anchor; it falls short of 5 because it rests on a single verb (Plan) rather than multiple distinct actions.

Completeness

It explicitly answers what ("Plan customer discovery interviews...") and when ("Use when preparing interviews for problem validation, churn research, or new product ideas") with concrete trigger phrases, matching the top anchor exactly; it is not 4 because the 'when' is explicit and specific, not merely present.

Trigger Term Quality

Natural phrases like "problem validation", "churn research", and "new product ideas" give good keyword coverage a user would actually say, matching the 'good coverage; a few natural terms missing' anchor; it is not 5 because synonyms like "user research" or "customer development" are absent.

Distinctiveness Conflict Risk

"customer discovery interviews" with triggers for problem validation, churn research, and new product ideas carves a clear niche with minimal overlap risk, matching the 'clear niche with distinct triggers' anchor; it is not 4 because the triggers are specific enough to avoid confusion with adjacent research skills.
