Conciseness

The ~46-line body is lean throughout: no concept explanations Claude already knows, no padding, and every rule earns its place (e.g. "A sentence that passes stays as written, so a second pass on the returned text changes nothing"). It matches the 'every token earns its place' anchor.

Actionability

Concrete, executable guidance for an instruction-only skill: an unambiguous mode-dispatch rule ("no draft means author; an imperative on a draft means edit; a question about a draft means detect"), per-mode outputs, and seven named checks. Not 5 because one sentence is hard to parse ("Note that the pattern catalog did not apply inside detect findings or inside a change line the caller asked for, and nowhere else.") and no pass/fail sentence examples are given, leaving minor execution gaps.

Workflow Clarity

Clear sequence (dispatch mode → apply tests → edit or detect → return), with explicit validation checkpoints: a "Done:" definition acting as a completion checklist ("every fact, number, name, quote, and citation in the input survives") and an idempotency check for edit mode ("a second pass on the returned text changes nothing"). Not destructive or batch, so no cap applies.

Progressive Disclosure

The body is a well-organized overview with two clearly signaled, real, one-level-deep references ("read `references/patterns.md`", "read `references/terminology.md`"), each loaded only when the inline tests do not settle a case; both files exist and are appropriately split out of the main body.

Specificity

"Rewrite, check, or draft prose" names three concrete actions mapping to the skill's three modes, each with concrete success criteria ("carries no AI writing tells, reads plainly on the first read, and keeps every source fact"). Coverage is comprehensive within its domain; not 4 because no capability area of the skill is left unlisted.

Completeness

It explicitly answers what ("Rewrite, check, or draft prose so it carries no AI writing tells...") and when ("Use when asked to make writing plainer or free of those tells, to check writing for them, or when drafting from supplied content") with concrete trigger phrases, matching the 5 anchor exactly.

Trigger Term Quality

Natural phrases like "make writing plainer", "free of those tells", and "check writing for them" match what a user would say. A few common synonyms are missing (e.g. "sound less AI", "humanize", "robotic writing"), so it falls just short of the comprehensive-synonyms anchor at 5.

Distinctiveness Conflict Risk

It carves out a clear niche (AI-tell-free prose with fact preservation) and even disambiguates a neighboring skill ("Use ce-promote for channel-specific marketing copy"), minimizing overlap risk; not 4 because the trigger conditions are specific to this skill's purpose rather than generic editing.
