Conciseness

The body is lean and directive throughout — 'Lead with the concrete thing', 'Explain after the example, not before', 'Use proof instead of adjectives' — with no padding and no explanation of concepts Claude already knows. Every line earns its place, matching the 'lean and efficient; every token earns its place' anchor above the 'minor instances of over-explanation' level (4).

Actionability

Guidance is concrete as directives (e.g., the explicit Banned Patterns list and the 'start sections with proof, artifact, conflict, or example' steps), but there are no executable code blocks, commands, or worked before/after examples — it instructs via rules rather than copy-paste artifacts. This fits the 'some concrete guidance but incomplete; missing key details' anchor, below the 'mostly executable guidance' level (4) which requires concrete code or commands.

Workflow Clarity

The Writing Process is a clear 5-step sequence and the Quality Gate is an explicit pre-delivery checklist acting as a validation checkpoint. It lacks a validate-fix-retry feedback loop, but this skill produces prose rather than destructive/batch operations, so the destructive-cap does not apply; minor checkpoint gaps place it at 'clear sequence with most checkpoints' rather than the full feedback-loop level (5).

Progressive Disclosure

Content is well-organized into clearly signaled sections (When to Activate, Core Rules, Voice Handling, Banned Patterns, Writing Process, Structure Guidance by type, Quality Gate) with the only cross-reference being a clearly signaled one-level pointer to the `brand-voice` skill. There are no bundle files present, so the structure is self-contained; it sits at 'good structure; most content appropriately placed' rather than a 5 because no detailed reference files exist to demonstrate one-level-deep splitting for the per-type guidance.

Specificity

Lists several concrete output types (articles, guides, blog posts, tutorials, newsletter issues) plus a concrete action (matching an existing founder/operator/brand voice from examples), though it stops short of naming every long-form variant. It sits above '1-2 concrete actions' (3) but the actions are output nouns rather than distinct transformational verbs, so it does not reach the comprehensive multi-action level (5).

Completeness

It explicitly answers 'what' (write long-form content types derived from supplied examples/brand guidance) and 'when' (an explicit 'Use when the user wants polished written content longer than a paragraph...' clause with concrete triggers). This matches the anchor that clearly and explicitly answers both what and when with concrete trigger phrases, exceeding the level (4) where 'when' could be more explicit.

Trigger Term Quality

Covers natural user phrasing comprehensively — 'articles, guides, blog posts, tutorials, newsletter issues', 'polished written content longer than a paragraph', and 'voice consistency, structure, and credibility' — including the common synonyms users would say when asking for long-form content. It matches the comprehensive-synonym anchor rather than the 'a few natural terms missing' anchor (4).

Distinctiveness Conflict Risk

The long-form-content framing plus 'voice consistency/structure/credibility' carve a fairly distinct niche with minimal overlap risk, but it could still rub against a generic writing or summarizing skill, so it sits at 'mostly distinct; minor overlap' rather than the 'clear niche, minimal conflict' anchor (5).
