Conciseness

The body is lean and fully operational: every section (Inputs, Workflow, NOT-do, Voice, Verification, Tools) issues instructions rather than explaining concepts Claude already knows, and the one framing sentence ("the index is the maintainer's first stop for navigation") earns its place by stating the goal. It matches the 'every token earns its place' anchor; not the 4 anchor, which requires trimmable over-explanation — none is evident.

Actionability

Guidance is fully executable for an instruction-only skill: exact entry format (`- [[<path>]] — <one-line summary>`), exact log-entry templates with field placeholders, concrete paths (`wiki/projects/<slug>/standup.md`, `wiki/log.md`), explicit skip rules, and named tools with their allowed write targets. This matches the 5 anchor ('copy-paste ready... specific examples cover the common cases'); the 4 anchor's 'minor gaps' do not apply.

Workflow Clarity

The 9-step workflow is clearly sequenced (read index, walk by category, scan the last ~50 log entries, produce sorted entries, drop dead entries, add missing ones, write editorially, preserve custom categories, append counts) and closes with an explicit pre-close Verification checklist covering the batch-write risks (dangling entries, modified page bodies). It falls short of the 5 anchor because there is no explicit validate→fix→retry feedback loop for this batch file-writing operation — the checklist gates closing the issue but does not tell the agent what to do when a check fails.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent), and the ~60-line body is appropriately self-contained with well-labeled sections — the rubric's 5-without-references exception is reserved for skills under 50 lines, which this slightly exceeds, so the 4 anchor ('good structure; most content appropriately placed; minor organization gaps') is the best fit. It is clearly above the 3 anchor: nothing that belongs in a separate file is inlined.

Specificity

The description lists several concrete actions — "Rebuild `wiki/index.md` from the actual wiki tree", "reconcile missing/deleted entries", "log counts without editing page bodies" — plus an explicit non-goal boundary. It falls just short of the 5 anchor because it omits part of the workflow covered in the body (e.g. walking categories, preserving custom sections), a minor coverage gap.

Completeness

Both questions are answered explicitly: "Use when an LLM Wiki operation issue requests an index refresh" gives a concrete when-clause, and the rebuild/reconcile/log actions with the "without editing page bodies" boundary give a clear what. It clearly matches the 5 anchor rather than the 4 anchor, whose 'when' is only partially explicit.

Trigger Term Quality

Relevant keywords are present ("index refresh", "LLM Wiki", "operation issue", "wiki/index.md") but they are domain-jargon heavy and miss natural user variations like "update/rebuild/sync the index", "index is out of date", or "standup". This sits between "some relevant keywords but missing common variations" (3) and "good keyword coverage" (4), closer to 3 because the natural-language phrasings a user would actually say are largely absent.

Distinctiveness Conflict Risk

The trigger is a narrow niche (an LLM Wiki operation issue specifically requesting an index refresh), making wrong-skill firing unlikely, though the description does not contrast itself with the closely related `wiki-lint` routine mentioned in the body, leaving minor overlap risk. Mostly distinct with minor overlap — the 4 anchor.
