Conciseness

The 310-line body is mostly skill-specific policy rather than explanation of concepts Claude already knows, but it is heavily padded with restatement: the editing-pass budget is explained in "Iterate to convergence," again in the marks pass, twice in "Rewrite mode (default)," and again in "Edit mode"; protected-content rules appear in the Editing contract, the marks pass, and the Verification sections. The ~20-line detector-research digression (Liang et al., Jabarian & Imas, arXiv citations) and lawyerly restatements like "A pass count alone is not a stop reason" could be cut to roughly half the length. Not 2: nearly every paragraph carries a skill-specific rule rather than filler or generic explanation.

Actionability

Guidance is largely executable: exact commands with flags and exit codes ("node scripts/normalize-quotes.js <rewritten-prose> --reference <original> --write", "node scripts/check-style.js <file> --config <path>" with "exit 0 clean / 1 hard violation / 2 tool error"), quoted mode-trigger phrases, and per-mode numbered step lists with required output sections. Not 5: "examples/README.md" and "examples/<name>.json" are cited as the schema documentation for --style configs but the examples/ directory does not exist in the bundle, so that guidance dead-ends.

Workflow Clarity

Each mode has a clear numbered sequence (rewrite: audit → rewrite → summarize; edit: read → minimal in-place edits → re-read and verify) with explicit validation checkpoints — the four-item Verification checklist (Editing passes, Checks, Residuals, Stop reason), the before-delivery source comparison, the mechanical preservation validator, and feedback loops (repair within remaining pass budget, re-validate, report unresolved failures). Not 4: validation is not merely present but structurally required at every exit point, including no-op and failure paths.

Progressive Disclosure

The single deep reference (references/patterns.md) is well signaled with a mandatory-load directive and holds the pattern catalog, and scripts are referenced by path — one level deep, matching the anchor-4/5 structure. Not 5: the bundle structure is inconsistent with the body — "examples/README.md", "examples/<name>.json", and "detector/validate.js" are referenced but absent, while bundled scripts/markdown-prose.js is never mentioned anywhere in SKILL.md.

Specificity

The description lists multiple concrete capabilities — "Audit and rewrite content to remove AI writing patterns ('AI-isms')", a "detect-only mode", an "edit-in-place mode for files", an "optional voice profile (casual / professional / technical / warm / blunt)", and an "iterate-to-convergence pass" — giving comprehensive, distinct coverage of what the skill does. Not 4: the actions enumerated cover every operational mode of the skill, not just several with gaps.

Completeness

It explicitly answers both questions: the "what" is stated up front ("Audit and rewrite content to remove AI writing patterns") and the "when" is given as concrete quoted trigger phrases ("Use this skill when asked to..."). This matches the anchor-5 example structure of a clear what followed by explicit trigger phrases.

Trigger Term Quality

Five natural trigger phrases are quoted verbatim ("remove AI-isms," "clean up AI writing," "edit writing for AI patterns," "audit writing for AI tells," "make this sound less like AI"), which is good coverage. Not 5: common user phrasings for this exact task are missing — "humanize this," "make this sound human/human-written," and "de-slop" are frequent ways users ask for exactly this and none appear.

Distinctiveness Conflict Risk

The niche is distinct — AI-ism removal — and the triggers are anchored to AI-specific phrasing ("audit writing for AI tells," "make this sound less like AI"), which a generic editing or proofreading skill would not claim. Minimal conflict risk with other skills.
