Conciseness

The body is lean bullet-based guidance with no explanations of concepts Claude already knows, matching the 4 anchor (efficient, minor trims possible). Not 5 because the opening line duplicates the frontmatter description verbatim, the Philosophy/Avoid sections partially overlap Anti-Patterns, and "Schema-bound outputs include `schema_version`" is cryptic filler.

Actionability

Concrete copy-paste commands cover the common cases: `mise doctor`, `mise --version`, `which mise`, `mise cache path`, `mise install`, `mise list`, `mise trust <path>`, `mise cache prune --dry-run`, `brew upgrade mise`, `mise self-update --yes`, `mise upgrade --dry-run`, plus three realistic example requests — matching the 5 anchor.

Workflow Clarity

The five-step workflow has explicit fail-fast checkpoints ("Stop at the first failed gate or blocker and report exact evidence") and a validation feedback loop ("do not proceed until it is fixed and rerun"; "rerun `mise doctor` and the original failing command"), matching the 5 anchor with explicit validation and error-recovery loops.

Progressive Disclosure

Sections are well organized and the deferred context is one level deep with a "Load only the specific archived file" rule, matching the 4 anchor. Not 5 because the referenced path `Infrastructure/references/deferred-skill-context/agent-ops-fix-mise/` does not resolve within the skill bundle — the bundle's `references/` directory holds contract/evals/task-profile files, none of which the body links to.

Specificity

"Diagnose, fix, and validate mise runtime failures" lists several distinct actions in a named domain, matching the 4 anchor (several specific actions, minor gaps). It falls short of 5 because coverage of trust prompts, cache writes, and binary updates appears only in the 'when' clause, not the 'what'; it exceeds 3 because more than 1-2 concrete actions are named.

Completeness

Explicitly answers both questions: the 'what' is "Diagnose, fix, and validate mise runtime failures" and the 'when' is a concrete "Use when commands fail from mise config, missing runtimes, stale pins, trust prompts, or shell activation drift" clause — a direct match for the 5 anchor.

Trigger Term Quality

"mise config", "missing runtimes", "stale pins", "trust prompts", and "shell activation drift" are natural phrases users would say when hitting these failures. Not 5 because common synonyms and concrete artifacts are missing (e.g., `.mise.toml`, `mise doctor`, "mise not installed").

Distinctiveness Conflict Risk

"mise" names a specific tool with a distinct failure domain, so the description occupies a clear niche with trigger terms unlikely to fire for unrelated skills — matching the 5 anchor.
