Lists multiple specific concrete actions: 'audience research, competitive landscape, category dynamics, problem space, and positioning territory exploration.' It also specifies the context ('very start of a brand or website project') and what the user needs to understand.

Clearly answers both 'what' (run upstream brand discovery covering audience research, competitive landscape, etc.) and 'when' (at the very start of a brand or website project, with explicit trigger terms listed and an additional conditional trigger for creative briefs missing upstream inputs).

Excellent coverage of natural trigger terms users would say: 'brand discovery, audience research, market research, competitive scan, category research, customer research, who is this for, who are we, positioning research, intake, kickoff.' These are highly natural phrases a user would actually use.

Occupies a clear niche as an upstream/discovery-phase brand research skill, distinct from execution-phase skills like design, copywriting, or website building. The explicit scoping to 'very start of a brand or website project' and the specific trigger terms reduce conflict risk significantly.

The skill is well-structured but somewhat verbose for Claude's capabilities. Sections like 'When to use' and 'When NOT to use' are helpful but could be tighter. Explanations like 'The third is most often forgotten and most often the actual competitor' and the failure patterns section add useful context but some entries explain things Claude would already understand (e.g., what demographic/psychographic means). Overall mostly efficient with some trimming opportunities.

The skill provides a solid conceptual framework with clear categories, sources, and outputs for each dimension. However, it lacks concrete executable examples—no sample discovery report snippet, no example audience profile, no example competitor matrix row. The guidance is specific in structure but abstract in execution; Claude would need to interpret rather than follow copy-paste-ready templates inline.

The 8-step workflow is clearly sequenced and logical. However, there are no validation checkpoints or feedback loops—no step says 'verify audience segments against data before proceeding' or 'review competitor matrix for completeness before territory generation.' For a multi-step discovery process where errors compound downstream, the absence of explicit validation gates is a notable gap.

The skill references two external files (discovery-report-template.md and interview-guide.md) and cross-references other skills (creative-brief, brand-ideation, seo-competitor). However, no bundle files were provided, so the references are unverifiable. The main content is quite long (~200+ lines) with detailed framework content inline that could potentially be split into reference files, particularly the per-dimension details.
