Conciseness

The body is lean runtime instructions throughout (e.g., 'Default to audit-only', 'Never delete meaningful content silently; move long explanation, examples, templates, or schemas into local references/'), with zero tutorial background and every token earning its place, matching the anchor-5 example of assuming Claude's competence.

Actionability

Guidance is fully executable for an instruction-only skill: exact file paths with fallback chains ('Read docs/skill-style-guide.md; if unavailable, read references/skill-style-guide.md; if neither exists, enforce the core LLM-first structure'), enumerated audit criteria, and a concrete command ('gentle-ai skill-registry refresh'); the Decision Gates table and Output Contract give unambiguous instructions for every fork.

Workflow Clarity

The five Execution Steps are clearly sequenced with fallbacks and an output contract, and apply mode ends with a rerun/registry-refresh checkpoint; however, for a batch multi-file editing operation the post-apply validation is terse and partly implicit ('then rerun or request gentle-ai skill-registry refresh' does not specify re-running the audit or a fix-and-revalidate loop), fitting anchor 4 rather than 5.

Progressive Disclosure

Scored against the actual bundle: references/skill-style-guide.md exists, is clearly signaled both in Execution Steps (as the documented fallback) and in the References section with per-file purpose annotations, and is exactly one level deep; the ~45-line body is well organized into the required section order with no content that belongs in a separate file inlined, and docs/skill-style-guide.md / .atl/skill-registry.md are repo-environment files with explicit fallback handling rather than nested references.

Specificity

"Audit and upgrade existing LLM-first skills" names the domain plus two concrete actions, matching the 1-2-actions anchor; it stays below anchor 4 because it gives no detail on what the audit or upgrade covers (e.g., frontmatter, triggers, structure).

Completeness

Both what ("Audit and upgrade existing LLM-first skills") and when (explicit "Trigger:" clause with concrete phrases) are present, so the missing-'Use when' cap does not apply; it is not anchor 5 because the when is a bare keyword list rather than an explicit situational clause like "Use when the user asks to improve an existing skill".

Trigger Term Quality

"improve skills, audit skills, refactor skills, skill quality" are natural phrases a user would say, giving good keyword coverage; it falls short of anchor 5 because common variants like "review skills", "fix skills", or the file name "SKILL.md" are absent.

Distinctiveness Conflict Risk

Auditing/upgrading existing skills is a distinct niche with clear triggers, but there is minor overlap risk with a skill-creation skill that the description itself does not disambiguate (only the body does via the skill-creator note), so it fits anchor 4 rather than anchor 5.
