Conciseness

Dense and purposeful — weighted dimension list, 1–5 anchors, ordered data-collection sources, and a copy-paste profile card template with no filler or explanation of concepts Claude already knows. Not 5: the 'never average the tension poles / target quadrant' point is repeated in four places and 'no score without evidence' appears twice, so a tightening pass would save tokens.

Actionability

Fully executable for an instruction-only skill: numbered dimensions with exact weights, explicit 1–5 anchor rubrics, a cheapest-signal-first source order, a 'What to record per dimension' contract ('the score, one-line justification, and the source link/screenshot'), and a complete profile-card template with every table row specified. Not below 5: no missing key details for the common case.

Workflow Clarity

Clear sequence with explicit checkpoints: activate on a scoped set → establish the positioning brief → score in source order → 'Calibrate across the set, not in isolation... Adjust outliers' (an explicit feedback loop before finalizing) → emit cards → hand off to competitive-report-structure. 'No score without evidence' acts as a per-dimension validation gate.

Progressive Disclosure

No bundle files exist (no references/, scripts/, or assets/), so the skill is self-contained with well-organized, clearly headed sections. Not 5: at ~190 lines it exceeds the simple-skill case, and the generic anchor rubrics or the profile-card template could be split into a one-level-deep reference file to slim the always-loaded body.

Specificity

Names concrete actions — 'Scores each competitor across nine weighted dimensions (positioning, voice, visual craft, ...)' 'with explicit 1–5 rubrics and a tension-plot' — with the dimensions fully enumerated. Not 5: only ~3 verbs and the profile-card output artifact is not mentioned.

Completeness

Both present: 'Use after competitive-platform-analysis has produced a tiered competitor set' is an explicit when-clause, and the scoring activity is a clear what. Not 5: the 'when' only expresses pipeline position (after X, precedes Y), not user-facing trigger phrases like 'when the user asks to benchmark their competitors'.

Trigger Term Quality

Contains some relevant keywords ('competitor', 'positioning', 'pricing', 'evidence', 'tension') but misses the natural phrases a user would say — 'benchmark competitors', 'score competitors', 'competitive analysis' — and never uses the word 'benchmark' despite the skill's name. Not 4: keyword coverage is not good enough to be missing only 'a few' natural terms.

Distinctiveness Conflict Risk

A clear niche with distinct triggers: tightly scoped to sibling skills ('Use after competitive-platform-analysis', 'Precedes competitive-report-structure'), nine named dimensions, and a tension-plot — minimal risk of firing for the wrong skill.
