Conciseness

The body is dense with Obsidian-specific facts Claude cannot be assumed to know (filename-resolved wikilinks, rename-in-app vs. move_file breaking links, Bases vs. Dataview tradeoffs), but there are minor instances that could be trimmed: "unlinked mentions" is explained in both the Wikilinks and Orphan sections, the intro paragraph restates the frontmatter description, and "Bases is built in since Obsidian 1.9" embeds a version number. This fits the score-4 anchor (efficient, minor over-explanation) better than score 5 (every token earns its place).

Actionability

Fully concrete, copy-paste-ready guidance throughout: exact wikilink syntax variants, a complete MOC template, a full frontmatter baseline block, three executable Dataview queries, a folder layout, and named tool commands (start_search, edit_block, write_file). It fits the score-5 anchor (specific examples covering the common cases), not score 4, which allows minor gaps.

Workflow Clarity

The Workflows section sequences four multi-step processes and the "Checklist before finishing" provides explicit verification, and destructive/batch operations (delete-after-dedupe, repointing links) include a pre-delete check ("start_search for inbound [[links]] to the discarded note and repoint them before deleting"), so the destructive-operation cap at 3 does not apply. However, there are no error-recovery feedback loops (what to do when a search or edit fails), which keeps it at the score-4 anchor rather than score 5.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent) and the single 190-line body is well-sectioned with clear headers, so navigation is easy. But reference-like material (the MOC/frontmatter templates and the Dataview query catalog) is inlined with no external references at all, which fits the score-4 anchor (good structure, minor organization gaps) rather than the score-5 anchor, which expects well-signaled one-level-deep references.

Specificity

The description lists multiple concrete actions with comprehensive coverage: "creating Maps of Content, adding/fixing wikilinks, finding orphan notes, normalizing YAML frontmatter, generating Dataview/Bases dashboards, organizing folders, deduplicating or renaming notes, and preparing the vault for AI use" — matching the score-5 anchor rather than the score-4 anchor, which requires minor gaps in coverage.

Completeness

It explicitly answers both what (the enumerated action list) and when ("Use ONLY when the user explicitly refers to Obsidian — by naming 'Obsidian', an Obsidian 'vault'... or the Dataview or Bases plugins"), plus a negative boundary ("Do NOT use this skill for generic note-taking, Markdown, or knowledge-base requests"). This exceeds the score-4 anchor, whose 'when' clause is less explicit.

Trigger Term Quality

Natural trigger terms are comprehensive and include synonyms and feature-specific vocabulary users would actually say: "Obsidian", "vault", "wikilinks ([[ ]])", "Dataview", "Bases", "Properties", "orphan notes", "MOCs", "dashboards". It fits the score-5 anchor (natural terms including synonyms); score 4 would require natural terms to be missing, and the only omissions (e.g. "backlinks") are peripheral to triggering.

Distinctiveness Conflict Risk

Clear niche (Obsidian-only) with distinct triggers and an explicit exclusion clause preventing overlap with generic Markdown, note-taking, and knowledge-base skills — minimal conflict risk, matching the score-5 anchor. Score 4 would require minor overlap risk with closely related skills, which the exclusion clause largely forecloses.
