Conciseness

Dense, information-rich prose with no explanation of concepts Claude already knows; the smell/why/fix table delivers maximal information per token. Only minor trimming exists: the PRD exception is explained both in the intro ("belong in PRDs... never in a skill body") and again at the end ("This does not apply to PRDs... per prd-writing"), and a few sentences could be tightened. Anchor 4 (efficient, minor trimming possible), not 5 due to that slight redundancy, well above anchor 3.

Actionability

Fully executable guidance: copy-paste-ready grep commands in the sweep section, a smell/why/fix table quoting exact offending phrases with their fixes, and a named validation script ("scripts/check_skill_pairs.py") with an explanation of what it flags. Matches anchor 5's copy-paste-ready commands covering the common cases.

Workflow Clarity

The sequence is discernible and validated: apply the rules, run the grep sweep, "Read every hit in context", fix the violations, then sync the three trees, with checkpoints (the sweep itself, the pair-check script, and the manual-diff advice). But the steps are presented as reference sections rather than an explicitly ordered procedure with numbered steps, leaving minor gaps that fit anchor 4 rather than anchor 5's explicit sequenced workflow with feedback loops.

Progressive Disclosure

No bundle files exist (no references/, scripts/, or assets/ directories), so the ~55-line body is appropriately self-contained for a simple, single-purpose skill. Sections are well-organized with clear headers, and external pointers (skills-index, prd-writing, check_skill_pairs.py) are one level deep and well-signaled, matching anchor 5 per the simple-skill guideline.

Specificity

Lists several concrete actions ("state current behavior only", "prefer plain, short wording", "plus the grep sweep to run before calling a doc clean", "PRDs are the deliberate exception"), but it advertises "the two standing rules" while the body actually teaches three rules plus cross-tree sync, so coverage has minor gaps. This matches anchor 4 (several specific actions, minor gaps) rather than anchor 5's comprehensive coverage, and is well above anchor 3's 1-2 actions.

Completeness

Both questions are answered explicitly: what ("Covers the two standing rules for living-reference prose... plus the grep sweep to run before calling a doc clean") and when ("Read before writing or editing any SKILL.md, or any research/audit doc in .gemini/internal-docs/research/") with concrete trigger phrases. This is exactly anchor 5; the explicit 'when' clause also avoids the completeness cap of 3.

Trigger Term Quality

Natural trigger phrases like "writing or editing any SKILL.md" and "research/audit doc" match what a user would say, supplemented by "grep sweep", "PRDs", and "correction trail". A few natural terms are missing (e.g. "skills" generically, "documentation", "cleanup"), fitting anchor 4 rather than the sparse keyword set of anchor 3 or the synonym-complete coverage of anchor 5.

Distinctiveness Conflict Risk

It carves out a clear niche (living-reference prose hygiene for SKILL.md and audit docs) with distinct triggers, and actively manages the boundary with its sibling skill via "PRDs are the deliberate exception (they keep a correction trail)". Matches anchor 5's clear niche with minimal conflict risk, not anchor 4 which would require unaddressed overlap with a closely related skill.
