Conciseness

The body is lean and assumes competence — no padding, no explaining concepts Claude already knows, concrete before/after examples like '"perform an evaluation of" becomes "evaluate"'. Anchor 4 ('efficient; minor instances that could be trimmed') fits better than 5 because a few lines (e.g., the Notes on vendored paths, the rationale sentence about reviewers) carry slightly more context than strictly necessary, though nothing is wasted enough to drop to 3.

Actionability

Guidance is fully executable and copy-paste ready: `git checkout -b fix/issue-<number>-<short-desc> main`, `scripts/lint.sh <changed-markdown-files>`, the complete commit heredoc with mandatory body, and `git log --all --full-history -- "**/filename.md"` for renames. This matches anchor 5 — specific commands cover the common cases, including validation of staged files via `git diff --cached --name-only`.

Workflow Clarity

The numbered workflow (branch → read then edit → front matter check → validate → self-review → commit) is clearly sequenced with explicit validation checkpoints: automated rumdl after each edit via the PostToolUse hook, manual lint after all edits, re-reading changed files, `git diff` verification of intended changes, and staged-file verification before commit. This matches anchor 5's 'clear sequence with explicit validation steps; feedback loops' — including fixing lint errors before proceeding.

Progressive Disclosure

Sections are well-organized and the body stays lean (~105 lines), pushing style detail to referenced files (AGENTS.md, STYLE.md, CLAUDE.md, COMPONENTS.md) one level deep. However, the actual bundle contains only scripts/post-edit.sh — none of the referenced guideline files exist in the bundle, and their location (bundle vs. repo) is not clearly signaled, matching anchor 4 ('good structure; references mostly clear; minor organization gaps') rather than anchor 5's well-signaled, verifiable references.

Specificity

The description lists several concrete actions — 'Write or edit reader-facing technical prose', 'handles edits, formatting, self-review, and commits' — with only minor coverage gaps (e.g., no mention of specific doc types it edits like READMEs or blog posts). It sits at anchor 4 ('lists several specific actions; minor gaps') rather than 5 because coverage is not fully comprehensive, and well above anchor 3 since it names multiple actions, not just 1-2.

Completeness

It explicitly answers 'what' ('Write or edit reader-facing technical prose for immediate comprehension... handles edits, formatting, self-review, and commits') and 'when' with concrete trigger phrases ('Use for documentation, PR titles and descriptions... Also use when asked to make writing clearer...'), plus a negative trigger ('Do not use for code-only tasks'). This matches anchor 5 exactly; anchor 4 would require the 'when' to be less explicit, but here triggers are concrete and multiple.

Trigger Term Quality

Natural trigger phrases users would say include 'documentation', 'PR titles and descriptions', 'release notes', 'design documents', and 'make writing clearer, more natural, less AI-generated, or easier to read'. A few common variations (e.g., 'docs', 'README', 'blog post') are missing, matching anchor 4 ('good keyword coverage; a few natural terms missing') rather than anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The niche is clear — reader-facing prose quality, 'less AI-generated' writing, PR descriptions — with distinct triggers and an explicit exclusion for code-only tasks. Minor overlap risk remains with general documentation-fixing and commit-message skills, matching anchor 4 ('mostly distinct; minor overlap risk with closely related skills') rather than anchor 5's minimal conflict risk.
