Conciseness

The body is dense and operational throughout (e.g. 'direct, compressed, concrete', 'parentheticals are for qualification, narrowing, or over-clarification'), with almost no explanation of concepts Claude already knows. A few editorial lines could be trimmed ('The point is not literary criticism. The point is operational reuse.'), which matches anchor 4's 'minor instances of over-explanation that could be trimmed' rather than anchor 5's every-token-earns-its-place.

Actionability

The guidance is fully executable for an instruction-only skill: a 4-tier source priority list, numbered collection steps with concrete parameters (5-20 samples, 'use `x-api` to pull recent original posts'), a 9-item extraction checklist, named hard bans, and an output contract pointing to an exact schema in references/voice-profile-schema.md, which exists and provides a copy-paste-ready template. This matches anchor 5's fully executable, specific-examples-cover-common-cases.

Workflow Clarity

The sequence is coherent and clearly ordered (When to Activate -> Source Priority -> Collection Workflow -> What to Extract -> Output Contract -> Downstream Use), but there is no validation checkpoint confirming the produced VOICE PROFILE against the source set before reuse. Anchor 4's 'clear sequence with most checkpoints present; minor validation gaps' fits; the skill is not a destructive or batch operation, so the workflow-clarity cap does not apply.

Progressive Disclosure

The body is a clear, well-sectioned overview, and its single bundle reference ('Use the schema in [references/voice-profile-schema.md](references/voice-profile-schema.md)') is real, one level deep, clearly signaled at the point of need, and holds the bulk of the output template. This matches anchor 5's clear overview with well-signaled one-level-deep references and appropriate content split.

Specificity

Names the domain and two concrete actions ('Build a source-derived writing style profile from real posts, essays, launch notes, docs, or site copy, then reuse that profile across content, outreach, and social workflows') with enumerated inputs and outputs. It falls short of anchor 5's 'multiple specific concrete actions; comprehensive coverage' since the action verbs are limited to build and reuse.

Completeness

Explicitly answers both what (build and reuse a source-derived writing style profile) and when ('Use when the user wants voice consistency without generic AI writing tropes'). The when-clause is present and explicit but covers only the voice-consistency trigger, missing triggers for the outreach, launch-post, and channel-adaptation use cases, so anchor 4 ('when could be more explicit or specific') fits better than anchor 5.

Trigger Term Quality

Includes natural phrases users would say such as 'voice consistency', 'writing style profile', and 'generic AI writing tropes', plus source-type keywords (posts, essays, launch notes, docs, site copy). A few natural synonyms are missing (e.g. 'brand voice', 'tone', 'sound like me'), matching anchor 4's 'good keyword coverage; a few natural terms missing' rather than anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

'Voice consistency' and 'generic AI writing tropes' carve a fairly distinct niche with a clear dedicated purpose, but the tail 'content, outreach, and social workflows' is broad enough to overlap with general content-writing skills, matching anchor 4's 'mostly distinct; minor overlap risk' rather than anchor 5's minimal conflict risk.
