Conciseness

The body is lean throughout: no concept explanations Claude already knows, no padding, and every line is directive ('Make the minimal change that fixes the issue', 'Don't interrupt a procedure... to insert a related fact'). Matches the 5 anchor: every token earns its place.

Actionability

Fully executable guidance: copy-paste-ready branch, lint, stage-verify, and heredoc commit commands with clear placeholders, plus concrete before/after rewrite pairs ('post-update configuration validation' becomes 'validate the configuration after the update'). Nothing is pseudocode or abstract-only, matching the 5 anchor.

Workflow Clarity

A clearly numbered branch→edit→front-matter→validate→self-review→commit sequence with explicit validation checkpoints ('Fix errors and warnings on lines you added or changed', 'Run git diff and verify only intended changes are present', 'git diff --cached --name-only') and a fix-and-review feedback loop. This matches the 5 anchor's explicit validation and error-recovery requirements.

Progressive Disclosure

Good single-file structure with well-organized sections and a one-level-deep reference pattern (hook script verified at scripts/post-edit.sh). However, the body cites AGENTS.md, STYLE.md, CLAUDE.md, COMPONENTS.md, and scripts/lint.sh, none of which exist in the bundle — a clear structure with unverifiable external references, keeping it at the 4 anchor rather than 5.

Specificity

Names the domain ('Write or edit reader-facing technical prose') plus several concrete deliverable types (documentation, PR titles and descriptions, release notes, design documents, substantive comments) and post-fix actions ('handles edits, formatting, self-review, and commits'), but action coverage is slightly thinner than the deliverable enumeration. Not 5 because a few plausible actions (e.g., restructuring a document) are not covered; clearly above 3 given the multiple specific actions listed.

Completeness

Explicitly answers both questions with concrete trigger phrases: what ('Write or edit reader-facing technical prose for immediate comprehension') and when ('Use for documentation, PR titles and descriptions... Also use when asked to make writing clearer...'), plus an explicit negative trigger ('Do not use for code-only tasks with no prose deliverable'). Matches the 5 anchor directly.

Trigger Term Quality

Includes natural phrases users would actually say: 'documentation', 'PR titles and descriptions', 'release notes', 'clearer', 'more natural', 'less AI-generated', 'easier to read'. A few common variations (e.g., 'edit docs', 'rewrite this', 'make it sound human') are missing, keeping it just below comprehensive synonym coverage at 5.

Distinctiveness Conflict Risk

A clear reader-facing-prose niche with a disqualifier ('Do not use for code-only tasks with no prose deliverable') that sharply reduces wrong-skill triggering, but 'documentation' and 'PR descriptions' still overlap with general doc/commit-message skills. Not 5 due to that residual overlap with closely related skills; well above 3 because of the explicit boundary.
