Conciseness

There is no padding of concepts Claude already knows — the length is dense domain policy — but "Resolve the analysis target" substantially overlaps the Entry Router, prohibitions repeat ("Do not browse other product directories" / "browse $COMPETITORS_BASE to choose an unrelated product"), and Preflight prose like "A digest identifies bytes, not the requested edition, latest release, or completeness of the collection" could be tightened. Mostly efficient but several sections need consolidation, so it sits at the could-be-tightened anchor rather than the minor-trims one.

Actionability

Copy-paste-ready blocks cover the main paths: preflight git commands, clone with SSH/HTTPS fallback, `gh search repos` with exact flags and JSON fields, `nl -ba` citation practice, and script invocations with env vars and subcommands. Minor gaps keep it below 5: paths are placeholder-templated ("{product-slug}/{owner-repo}"), the HTTPS retry condition "only when that keeps the work moving" is vague, and Profile/Landscape steps defer to reference files.

Workflow Clarity

Sequence is clear — resolve target → route via the intent table → preflight with verification commands (test -d, remote -v, pinned commit) → discovery → ordered fact-gathering → report template → Output Quality Bar checklist — with a recovery loop for SSH failure. Below 5 because several checkpoints (mechanism evidence checks, final checklist details) are delegated to reference files rather than validated inline, and the two routing sections create mild sequencing ambiguity about which governs.

Progressive Disclosure

References are well-signaled, one level deep, purpose-stated at each link (e.g., "Before making mechanism-level claims ... read references/mechanism_evidence.md"), and every linked path and deep anchor resolves to a real file. Not 5 because references/original-app-demo.md exists in the bundle but is never referenced or navigable from SKILL.md.

Specificity

Multiple concrete actions are listed — "Clones and audits competitor repositories into evidence-based intelligence with file:line citations" plus track/add/review/compare/build-landscape/check-updates — covering every mode the skill supports, matching the comprehensive-coverage anchor.

Completeness

Explicitly answers both what ("Clones and audits competitor repositories into evidence-based intelligence with file:line citations") and when ("Use to track competitors, add a competitor repo, ... check for code updates"), with concrete trigger phrases plus a negative boundary ("Not for market research without code").

Trigger Term Quality

Natural phrasings users would say are comprehensively covered, including bilingual synonyms: "track competitors", "add a competitor repo", "competitor scan", "analyze competitor", "compare with X", "latest competitor code", "竞品分析 / 竞品". Not 4 because no commonly said variation is conspicuously missing.

Distinctiveness Conflict Risk

Clear niche — code-repository competitor intelligence with file:line citations — with an explicit disambiguation redirecting market research to deep-research, so conflict risk with adjacent research skills is minimal.
