Conciseness

The body is 19 lines with zero padding: a one-line trigger, five terse steps, and a four-item output format. It assumes Claude's competence (e.g. 'Call out unknowns explicitly instead of guessing' with no elaboration), so every token earns its place. Not 4 because there are no over-explanations to trim at all.

Actionability

Concrete, specific guidance throughout: exact constraint categories ('(versions, limits, required fields, auth, edge cases)'), a defined four-section output format, and explicit citation and unknowns requirements. As an instruction-only skill the absence of code is not penalized, but minor gaps remain — no example of a checklist entry or citation format. Not 5 because it never shows what the deliverable looks like; not 3 because the guidance is specific and directly executable rather than incomplete.

Workflow Clarity

Five clearly numbered, unambiguous steps in correct order (prioritize sources, capture constraints, convert to checklist, cite, flag unknowns). This is a non-destructive, single-purpose skill under 50 lines, so the simple-skill exception applies and the well-organized sequence scores 5 without explicit multi-step validation loops. Not 4 because nothing in the sequence is missing or implicit.

Progressive Disclosure

Under 50 lines with no need for external references (none exist in the bundle, and none are referenced). Per the judging guideline, well-organized sections alone warrant 5: the body is cleanly split into a trigger condition, a numbered process, and a labeled output format. Not 4 because there is no content that should be split out and navigation is trivial.

Specificity

Names the domain ("official, up-to-date documentation") and two concrete actions ("Gather... documentation", "convert it into a concise implementation checklist"), matching the anchor for 1-2 concrete actions without comprehensive coverage. Not 4 because it does not list several distinct actions; not 2 because the actions are specific rather than minimal or generic.

Completeness

It clearly answers 'what' (gather official docs, convert to implementation checklist) but has no 'Use when...' clause or equivalent explicit trigger guidance, which per the judging guidelines caps completeness at 3. Not 2 because the 'what' is concrete, not vague; not 4 because the 'when' is entirely absent rather than just imprecise.

Trigger Term Quality

Relevant keywords like "documentation", "implementation checklist", and "coding task" are present, but common natural phrases users would say ("check the docs", "latest API", "how do I use X") and synonyms/extensions are missing. This fits 'Some relevant keywords but missing common variations or synonyms', not 4, which requires good coverage with only a few gaps.

Distinctiveness Conflict Risk

The pairing of official docs with a checklist deliverable is somewhat specific, but "documentation" is a broad trigger that would overlap with general research, web-search, or API-reference skills. Fits 'Somewhat specific but could still overlap with similar skills'; not 4 because the trigger surface is not distinct enough to avoid overlap with closely related research skills.
