Conciseness

The body is lean and assumes Claude's competence — it names tools, paths, and formats without explaining concepts — e.g. 'Open the target space's `wiki/index.md` first' and the exact citation syntax. Minor trims exist: 'it is the navigation aid', 'The wiki points to `raw/` precisely so you can verify', and the Voice bullet 'The query response is itself a candidate for filing into `wiki/synthesis/`' restates step 5, which places it at the minor-trimming anchor rather than fully lean at 5.

Actionability

Fully concrete instruction-only guidance: named tools (`wiki_read_page`, `wiki_read_source`), exact citation formats ('(see [[wiki/concepts/managed-resources]])' or '(see raw/<filename>)'), concrete output structure ('Direct answer first, in 1–4 sentences'), and an exact log-entry format ('query | filed synthesis'). Per the scoring notes, absence of code is not penalized for instruction skills when guidance is this executable.

Workflow Clarity

A clearly sequenced 6-step workflow with explicit checkpoints: read the index before pages, verify thin claims against `raw/`, plain failure handling ('When the wiki cannot answer... Never bluff'), and a closing verification checklist ('Every claim in the answer cites a wiki page or raw source'). The opt-in guard on writing synthesis ('Do not write the synthesis page silently') and checklist coverage of the write path provide the validation the 5 anchor requires.

Progressive Disclosure

No bundle files exist, and the body is ~41 lines of well-organized sections (Inputs, Workflow, Voice, Verification, Tools) with no content that belongs in a separate reference file. Under the rubric's simple-skill note, a sub-50-line skill with no need for external references scores 5 on well-organized sections alone.

Specificity

Names the domain ('LLM Wiki operation issue' queries) and several concrete actions — 'Answer from wiki pages and raw sources with citations, name gaps plainly, and offer to file durable synthesis'. Actions are specific but slightly abstract (no mention of reading pages, following wiki-links, or the fallback path when the wiki cannot answer), leaving minor coverage gaps that keep it below the comprehensive anchor at 5.

Completeness

Explicitly answers both parts: 'Use when an LLM Wiki operation issue asks a question' gives the when with a concrete trigger, and 'Answer from wiki pages and raw sources with citations, name gaps plainly, and offer to file durable synthesis' gives the what. Both are clear and concrete, matching the top anchor; it does not fall to 4 because neither half is implicit or vague.

Trigger Term Quality

Includes natural terms a user in this environment would say — 'wiki', 'asks a question', 'query', 'citations', 'gaps'. Missing a few natural variations such as 'look up', 'search the wiki', or 'answer from the wiki', so it sits at good-but-not-comprehensive keyword coverage rather than the full synonym coverage of the 5 anchor.

Distinctiveness Conflict Risk

The trigger is tightly scoped to a query-type operation issue against a specific wiki space, a clear niche that is unlikely to fire for ingest/distill/write-style wiki skills. Third-person-imperative voice, no buzzwords or over-claims, so minimal conflict risk per the 5 anchor.
