Conciseness

The prose is dense and rule-only with zero padding or explanation of concepts Claude already knows, but it could be tightened: the editing-pass counting rules are stated four times (Workflow step 9, step 10, Repair path steps 1/4/6, Stop conditions), 'preserve content that already sounds human' appears at both line 24 and step 4, and step 7's protected-region rules repeat the Produce section. Not a 2 — there is no verbosity for its own sake — but the duplication is more than 'minor instances that could be trimmed', so anchor 3 fits better than 4.

Actionability

The orchestration guidance is concrete (named canonical voice profiles, explicit handoff envelope fields, a stepwise repair procedure with hard stop rules), and per the rubric's code_vs_instruction note the absence of code is not itself penalized. However, the two things that make the skill executable — the editing rules ('the complete rules in ../avoid-ai-writing/SKILL.md... is the authority') and the required Output format ('Follow the canonical ../avoid-ai-writing/SKILL.md rewrite-mode Output format') — are delegated entirely to a file that does not exist in this bundle, leaving key details missing. That is the anchor-3 case ('some concrete guidance but incomplete'), not 4 ('minor gaps').

Workflow Clarity

A clear 10-step sequence with validation checkpoints (audit before editing in step 3, review before presenting in step 9, verifier handoff in step 10) and a full feedback loop in the Repair path: check pass state, repair only implicated spans, return to the verifier once, then stop and report rather than cycling. This matches the anchor-5 example (validate → fix → re-verify → only-then-proceed) including error-recovery behavior.

Progressive Disclosure

References are clearly signaled with stated purposes and are only one level deep (../avoid-ai-writing/SKILL.md, ../avoid-ai-writing-router/references/handoff-contract.md, skill-graph.json, agency-role-lenses.md), which is structurally right. But none of those files resolve in this bundle — there is no local references/ directory and the sibling skills are absent — so the skill's core content lives in files that cannot be reached, and navigation effectively breaks. Clearly-signaled but non-resolving dependent references fall between the 'references present but not clearly signaled' anchor 3 and the well-split anchor 4; the missing files make it a 3.

Specificity

The description lists several concrete action verbs ("rewrite, humanize, clean up, or remove AI-isms from text") plus a rich preservation scope ("voice, facts, intent, structure, register, and protected material"). It stops short of anchor 5 because the verbs are largely synonyms for one de-AI-ifying rewrite operation and the deliverable (a returned rewritten text) is never named; not below 4 because coverage within the niche is thorough.

Completeness

Both halves are explicit: "Use when the user asks to rewrite, humanize, clean up, or remove AI-isms from text" answers *when* with concrete trigger phrases, and the same clause plus the preservation list answers *what*. This matches the anchor-5 pattern of the good examples.

Trigger Term Quality

"rewrite", "humanize", "clean up", and "remove AI-isms" are natural user phrasings with good synonym coverage. It misses a few common variations users actually say ("make it sound human/natural", "less robotic", "tone down the AI voice"), which keeps it below the comprehensive anchor 5 but comfortably above anchor 3.

Distinctiveness Conflict Risk

"remove AI-isms" carves a clear niche distinct from generic editing/grammar skills. Minor overlap risk remains with plain "rewrite/polish my text" requests and closely related sibling voice-editing skills, so it sits at anchor 4 rather than 5.
