Mostly efficient with genuinely specific operational detail (incentive rates, 20-30% no-show, recruit 7 to schedule 5, 5-15 participants), but ~250 lines include generic advisory prose ('Bad questions produce bad research', 'Findings die in slide decks') and an obvious Failure-patterns list that could be tightened.

Instruction-only skill with concrete, actionable guidance: named methods with participant counts, recruit ratios, dollar incentive ranges, and a copy-paste findings-document template; absence of code is not penalized here.

A clearly sequenced 9-step Workflow plus a 6-phase framework with explicit validation checkpoints — pilot 1-2 sessions before the main batch, 'test the insight against the data', and 'track impact'.

Body is well-sectioned and points to a single, real, one-level-deep reference (references/interview-guide-template.md, verified present), clearly signaled in a dedicated 'Reference files' section.

Lists multiple specific concrete actions — 'research planning, recruiting, interview design, qualitative synthesis, and translating findings into product decisions' — rather than vague language.

Explicitly answers both what ('Plan and execute user research including...') and when ('Use this skill whenever the user wants to...', 'Triggers on...').

Provides strong coverage of natural terms users would say — 'user research, UX research, user interviews, discovery research, generative research, formative research, qualitative research, user insights, research synthesis, recruitment, interview guide, jobs to be done.'

Clear generative/discovery research niche with distinct triggers; the body further disambiguates from usability-testing, journey-mapping, analytics-strategy, and cro-optimization.
