Conciseness

Mostly lean and assumes Claude's competence (env-var table, direct commands); minor over-explanation in the 'black-box witness' framing and rationale prose keeps it just below a 5.

Actionability

Provides concrete, mostly executable commands (llm-server status/issue, export+run invocation) and an exit-code-to-action table; not a 5 because placeholders like <mimocode> and <provider/model> prevent full copy-paste readiness.

Workflow Clarity

Setup is clearly sequenced (steps 1-3) and the expiry section gives an explicit feedback loop (exit 2 -> run renew_argv -> replace key -> retry once) with a full exit-code recovery table.

Progressive Disclosure

Well-organized into clear sections (needs, setup, expiry, prohibitions) with all content appropriately inline and no nested references; not a 5 because the body exceeds the ~50-line simple-skill threshold and there is no reference structure to signal.

Specificity

Names the domain ('temporary local LLM server') and several concrete mechanisms ('borrow a configured chat model through a local base_url and a throwaway token', 'expire-and-reissue loop'), with only minor coverage gaps; not a 5 because it frames roughly two actions rather than a comprehensive list.

Completeness

It explicitly states both what it is ('Demo and end-to-end fixture for MiMoCode's temporary local LLM server') and when to use it ('Use when verifying... or when testing the expire-and-reissue loop') with concrete trigger phrases.

Trigger Term Quality

The 'Use when verifying that a skill can borrow a configured chat model... or when testing the expire-and-reissue loop' clause gives good keyword coverage for its narrow niche; not a 5 because it lacks synonyms or file-extension variants.

Distinctiveness Conflict Risk

Highly niche triggers ('MiMoCode's temporary local LLM server', 'expire-and-reissue loop') plus the explicit 'Not a general-purpose skill' boundary give it a clear niche with minimal conflict risk.
