Conciseness

The body is dense with actionable material — symptom/action tables, a 10-question spec, a 12-token derivation table, and exact exit codes — with almost no explanation of concepts Claude already knows. Minor trims are possible: the 'Forcing-question library' canon justifications and the 'Distinct from' section restate rationale a reader can infer.

Actionability

Nearly everything is executable: exact commands ('python3 markdown-html/skills/design-system/scripts/onboard.py --set brand.primary=#FF6B35'), exit codes 3 and 4, and a worked-example block covering defaults, per-repo overrides, reset, --show, bypass, and contrast spot-checks. The gap keeping it from 5: the worked example uses 'python3 .../onboard.py' path abbreviations rather than copy-paste-ready full paths.

Workflow Clarity

Sequencing is explicit (symptom→action 'When to invoke' table; onboarding → config → converter consumption) with genuine validation checkpoints: brand_palette_validator.validate() runs after every change, saves are refused with exit 4 on contrast failure and exit 3 on unwritable output, and error recovery is spelled out ('pick a darker primary, blank brand.bg/brand.text ... or override brand.text directly'). This matches the validate → fix → retry anchor including for the destructive --reset path.

Progressive Disclosure

The body is well sectioned and correctly links assets/design_system_schema.json, but all three bundled reference files (references/design_token_canon.md, references/typography_pairing.md, references/wcag_accessibility.md) are never mentioned — the 'References' section lists external books instead. typography_pairing.md documents exactly the '12 safe defaults' the onboarding table alludes to, yet a reader of SKILL.md has no way to discover it; references present but not signaled.

Specificity

Multiple concrete actions with comprehensive coverage: 'Captures the user's brand identity once via a 10-question onboarding wizard', 'validates body-text and link contrast against WCAG 2.2 AA', 'derives 12 CSS custom properties in HSL space', 'Refuses to save if body-text contrast fails AA 4.5:1'. Third-person voice throughout, no fluff.

Completeness

Both questions are answered explicitly: 'what' via the enumerated wizard/validation/derivation/storage pipeline, and 'when' via 'Use before any markdown-html conversion. Triggers on first-run onboarding (...), on explicit reset (...)'. This matches the 5-anchor's 'what AND when with concrete trigger phrases' exactly; the 4-anchor's 'when could be more explicit' does not apply.

Trigger Term Quality

Natural phrases a user would actually say are quoted verbatim: 'set up the brand', 'configure markdown-html', 'run onboarding', 'reset the design system', 're-onboard', plus 'markdown-html conversion' — covering first-run, mutation, and reset vocabulary with synonyms. Not the level below (4) because it goes beyond good coverage to genuinely comprehensive natural phrasing.

Distinctiveness Conflict Risk

A clear niche — the shared brand owner for the markdown-html plugin — anchored by unambiguous scope markers ('every markdown-html converter', config_loader.py, ./.markdown-html/, ~/.config/markdown-html/). The quoted trigger phrases are specific to this skill and would not plausibly route to an unrelated one.
