Conciseness

Dense, non-pedantic, and assumes Claude's competence (no explaining what a usability test or thematic analysis is). Not a 5 because of trimmable redundancy: the three tools are described three times (Purpose bullets, Workflow steps, Scripts table), the 'Distinct from' table repeats the 'Do NOT use this skill to' list, and the forcing-question library largely restates anti-patterns and reference-file content. Above level 3, which would imply genuinely unnecessary explanation rather than structural repetition.

Actionability

Fully executable throughout: complete CLI invocations with flags ('study_designer.py --goal {discovery|evaluative|validation} --stage {...} --profile {...}', 'insight_synthesizer.py --input observations.json --min-sources 3'), onboarding and autoresearch commands, and a Quick examples section that states the expected behavior ('promotes "import-confusion" ... flags "wants-slack" as an ANECDOTE'). All referenced scripts exist with --help/--sample. Copy-paste ready, covering the common cases.

Workflow Clarity

A clear five-step sequence with explicit commands and real checkpoints ('Honor the redirect if it routes to experiment-designer', 'Record the confidence label and limits', 'Treat ANECDOTE-flagged clusters as signals to probe, not findings to ship'). Not a 5: there is no explicit verify/recovery loop after synthesis or repository filing (e.g., re-run the synthesizer after recoding, or audit that insights were tagged to the atomic schema), so it sits at 'clear sequence with most checkpoints; minor validation gaps'.

Progressive Disclosure

SKILL.md functions as an overview: three clearly-scoped reference files (methods canon, sampling/saturation, repository/synthesis) verified to exist, each one level deep with no nested references and each paired with its script; details are appropriately split out (saturation math and citations live in references, not the body). The Scripts table and one-line reference annotations make navigation easy.

Specificity

Lists three concrete, comprehensive actions with named methods: 'selecting the right method for the goal (generative interviews vs usability test vs concept test vs validation)', 'computing method-based saturation/sample size with an explicit confidence level', and 'synthesizing coded observations into insights while flagging single-source anecdotes'. Matches the level-5 anchor (multiple specific concrete actions, comprehensive coverage); below it there is no gap in action coverage to justify 4.

Completeness

Explicitly answers both: what ('selecting the right method... computing method-based saturation/sample size... synthesizing coded observations into insights') and when ('Use when planning and synthesizing product/user research...') with concrete trigger phrases. This matches the level-5 anchor exactly; level 4 would require a weaker or less explicit 'when' clause, which is not the case.

Trigger Term Quality

Good keyword coverage: 'product/user research', 'usability test', 'concept test', 'sample size', 'saturation', 'insights', 'anecdotes'. Not a 5 because the phrasing leans technical ('generative interviews', 'method-and-repository discipline') and omits plainer synonyms users naturally say, such as 'user interviews', 'discovery research', or 'how many participants'; clearly above the 'some relevant keywords but missing variations' anchor at 3.

Distinctiveness Conflict Risk

Establishes a clear niche ('this is the research-ops method + insight-repository layer') and explicitly disambiguates from product-team/ux-researcher-designer, product-team/product-discovery, product-team/experiment-designer, and market sizing. Minimal conflict risk; matches the level-5 'clear niche with distinct triggers' anchor.
