Conciseness

The body is efficient and domain-specific, with no explanations of concepts Claude already knows; the smell table delivers rules in a compact, token-dense format. Minor trimmable instances remain: the PRD exception is stated in the opening section and restated at the end of the research-docs section, and the final sync paragraph is somewhat long-winded.

Actionability

Fully executable guidance: two copy-paste-ready grep commands with concrete patterns, a literal smell/fix table showing example phrases and their replacements, and an operational test ("does this sentence describe the codebase, or a previous version of this document?"). Specific examples cover the common cases.

Workflow Clarity

The sweep workflow has a clear sequence with a validation checkpoint: run the greps, "Read every hit in context: some are legitimate", then fix, plus a verify hook via scripts/check_skill_pairs.py and a manual diff. It falls short of the top anchor because there is no explicit re-run loop confirming the sweep is clean after fixes, and no checklist form.

Progressive Disclosure

A roughly 55-line single-purpose rule set organized into well-labeled sections (Rule 1/2/3, the sweep, research-docs scope, three-tree sync) with no external bundle files and no content inlined that belongs in a separate file. Per the simple-skill guidance, well-organized sections with no need for external references earn the top score.

Specificity

The description names several concrete capabilities ("state current behavior only, and prefer plain, short wording", "the grep sweep to run before calling a doc clean") rather than vague language. It stops short of comprehensive coverage because the body contains a third rule (no em-dashes) that the description never mentions, leaving a minor gap.

Completeness

It explicitly answers "when" ("Read before writing or editing any SKILL.md, or any research/audit doc in .gemini/internal-docs/research/") and "what" (the standing rules plus the grep sweep), with the PRD exception boundary stated. Both halves are concrete and explicit, matching the top anchor rather than the 'when could be more explicit' anchor below it.

Trigger Term Quality

Natural triggers users would say are present: "writing or editing any SKILL.md", "research/audit doc", "PRDs". A few natural terms are missing (e.g. "skill files", "doc hygiene", "cleanup"), so keyword coverage is good but not comprehensive with synonyms.

Distinctiveness Conflict Risk

A clear niche (living-reference prose hygiene for this repo's skill and research docs) with distinct triggers and an explicit carve-out ("PRDs are the deliberate exception") that pre-empts overlap with the prd-writing skill. Minimal conflict risk with other skills.
