Conciseness

The body is lean overall — every rule uses compact bad/good example pairs — but has minor trimmable instances: 'Five facts drive every rule below' spends 11 lines on ADHD cognition Claude broadly already knows, and 'Vague estimates fail' is stated verbatim in both the facts section and Rule 6. This matches anchor 4 (minor over-explanation that could be trimmed), not 5, and is well above 3 since the padding is marginal.

Actionability

Fully concrete and executable for an instruction-only skill: enumerated forbidden phrases ('Great question,' 'Let me...'), a specific error-reporting format ('Test fails at `auth.spec.ts:42`: expected 200, got 401. Cause: missing auth header. Fix: add `Authorization: Bearer ${token}`'), concrete time estimates ('About 15 minutes if tests already cover this'), and a copy-paste-able pre-send checklist. This matches the top anchor for instruction skills; nothing remains vague.

Workflow Clarity

A single-purpose skill whose action is unambiguous, with an explicit validation checkpoint: the 'Pre-send check' section is a 5-item deletion checklist plus a final verification loop ('if the reader reads only the first line and the last line, do they know (a) what to do next, and (b) what just happened? If yes, send.'), and 'When to break the rules' enumerates edge cases including harness conflicts. Meets the simple-skill exception and the feedback-loop bar; not scored lower because no destructive/batch validation gap applies.

Progressive Disclosure

The skill is self-contained: no bundle files exist, no references are cited, and content is organized into clear H2/H3 sections (Rules, When to break the rules, Pre-send check) with no nesting. Splitting rules into reference files would harm a skill whose rules must be in context every turn, so the single-file structure with well-organized sections fully satisfies the simple-skill guidance.

Specificity

'Shape output for an ADHD reader: next action first, numbered steps, no tangents' names the domain and three concrete behaviors. Anchor 4 ('lists several specific actions; minor gaps in coverage') fits: the skill's ten rules include behaviors the description omits (concrete time estimates, matter-of-fact error tone, 5-item list cap, pre-send checks), so it is not comprehensive (5), but it exceeds the 1-2 actions of anchor 3.

Completeness

The 'what' is clear and concrete ('Shape output for an ADHD reader: next action first, numbered steps, no tangents'), and explicit trigger guidance exists ('Trigger: /i-have-adhd'), so the missing-trigger cap of 3 does not apply. However, the 'when' is terse — appropriate for a disable-model-invocation slash-command skill, but it could be more specific about when a user should invoke it. Matches anchor 4 ('both what and when; when could be more explicit or specific'), not 5.

Trigger Term Quality

'ADHD' is the core natural keyword a user would say, and 'numbered steps' and 'tangents' are natural phrasings. A few natural terms users might say are missing ('distracted,' 'overwhelmed,' 'keep it short,' 'step by step'), matching anchor 4 ('good keyword coverage; a few natural terms missing') rather than 5's synonym/variation coverage, and clearly above 3's partial coverage.

Distinctiveness Conflict Risk

A clear niche — output shaping for an ADHD reader — with a distinct trigger ('Trigger: /i-have-adhd'). No other skill category (formatting libraries, document tools, general brevity) would plausibly fire on these triggers, so conflict risk is minimal, matching anchor 5.
