Conciseness

The body is lean and operational throughout: frameworks (COM-B, B=MAP, EAST) are named but never taught, mode detection and required reading are terse tables, and the one example ('✗ "Get people to care about observability." / ✓ "Every engineer opening a PR that adds an API endpoint adds an OTel span to it"') earns its tokens. No section explains concepts Claude already knows, and nothing reads as padding.

Actionability

Guidance is concrete and directive ('Parse the first token of $ARGUMENTS', a numbered four-item context list, 'Every intervention carries its lever, the barrier it targets, the evidence grade'), but Steps 3–5 execute against files whose contents are absent from the bundle — 'run the three-question test in rules/ethics.md' and 'Fill the mode's template' cannot be carried out because rules/ethics.md and both templates are missing. This keeps it below fully-executable; it is well above the pseudocode/vague-hints level of 3.

Workflow Clarity

A clearly sequenced five-step workflow (pin behavior → gather context → run mode → ethics gate → emit) with an explicit validation checkpoint ('Any intervention that fails is dropped from the output and replaced by its honest alternative'), error-recovery paths ('proceed with unknowns and list every assumption'; a missing skill is reported 'skipped (not installed)' and work continues), and a six-item Hard Rules checklist governing the output. This is an advisory, non-destructive skill, so the batch/destructive validation cap does not apply.

Progressive Disclosure

The loading design itself is exemplary — 'Load on demand — never all up-front', a per-mode required-reading table, one-level-deep references with precise section pointers ('§ Evidence grading', '§ Diagnosis only'), and the one shipped bundle file (references/frameworks.md) is well-organized. But 7 of the 8 unique files referenced in the body (all five rules/*.md and both templates/*.md) do not exist in the bundle, and frameworks.md itself links back to missing ../rules/*.md files, so most referenced paths are broken in practice — a majority-scale navigation failure, not the 'minor organization gaps' of 4.

Specificity

Lists several concrete actions with named frameworks — 'Applies behavioral science (COM-B, B=MAP, EAST, defaults) to change behavior', 'plans rollouts, workshops, and presentations', 'never recommends a dark pattern or sludge' — but omits the barrier-diagnosis and rollout-review capabilities the body documents, so coverage has minor gaps. It is well above the 1–2-concrete-action level of 3 and short of comprehensive coverage.

Completeness

Explicitly answers both questions: what — 'Applies behavioral science … to change behavior in teams and organizations … and in product flows; plans rollouts, workshops, and presentations' — and when, with a dedicated trigger clause ('Triggers on …') listing concrete quoted phrases. The 'when' is explicit and phrase-level, not merely present, matching the top anchor rather than the 4 anchor's 'could be more explicit'.

Trigger Term Quality

Natural user phrasings are quoted directly — 'how do I get my team to X', 'why don't people do X', 'roll this out', 'nudge' — which a manager would genuinely say. A few natural terms are missing, though: 'adoption', 'change management', and 'buy-in' appear in the body's mode table and tags but not the description, keeping it below comprehensive synonym coverage.

Distinctiveness Conflict Risk

A clear behavioral-science niche with distinctive triggers ('nudge', 'why don't people do X') that few other skills would claim. Minor overlap risk remains: 'plans rollouts, workshops, and presentations' brushes against generic workshop/presentation skills and 'product flows' against UX skills, so it is mostly rather than fully distinct.
