Conciseness

The body is lean and assumes Claude's competence: vault location, naming conventions, linking rules, and copy-paste bash commands with zero padding or explanation of concepts Claude already knows (e.g., "Mostly flat at root level" conveys structure in four words). Every token earns its place, matching the top anchor.

Actionability

The search, backlink, and index workflows give fully executable copy-paste bash commands, but the create workflow references undefined conventions: "Write content as a unit of learning (per vault rules)" and "use the hierarchical numbering scheme" without specifying either. This fits 'mostly executable guidance with minor gaps' rather than the fully copy-paste-ready top anchor.

Workflow Clarity

Each workflow is a clear, unambiguous single-action sequence, and the operations are non-destructive so no validation checkpoints are required. It falls short of 5 because the note-creation steps depend on the unspecified "vault rules" and "hierarchical numbering scheme", leaving that workflow incompletely defined; it is above 3 because sequences are explicit and steps are well-separated.

Progressive Disclosure

This is a simple skill (~54-line body, single purpose, no bundle files) whose content fits entirely in SKILL.md with no need for external references. Sections (Vault location, Naming conventions, Linking, Workflows) are well-organized and easy to navigate, which the rubric's simple-skill guidance says can score 5 with just well-organized sections.

Specificity

The description lists several specific actions ("Search, create, and manage notes") and adds concrete mechanism detail ("with wikilinks and index notes"), matching the anchor for several specific actions with minor gaps. It is not a 5 because "manage" is generic compared to a fully concrete action list, and not a 3 because more than 1-2 concrete actions are explicitly named.

Completeness

It explicitly answers both what ("Search, create, and manage notes in the Obsidian vault with wikilinks and index notes") and when ("Use when user wants to find, create, or organize notes in Obsidian") with concrete trigger phrases, matching the top anchor exactly. The when-clause specificity exceeds the anchor-4 example ('Use when working with PDF files').

Trigger Term Quality

Natural phrases like "find, create, or organize notes in Obsidian" map well to what users would actually say, giving good keyword coverage. It falls short of the comprehensive anchor (5) because common synonyms such as "knowledge base", "backlinks", or "linking notes" are missing, but it is well above the partial-coverage anchor (3).

Distinctiveness Conflict Risk

"Obsidian vault" pins a clear niche with distinct triggers, but the skill could still fire for generic note requests ("create a note") where Obsidian is not mentioned, creating minor overlap risk with generic note-taking skills. This fits 'mostly distinct; minor overlap risk' rather than the minimal-conflict top anchor.
