Conciseness

The body never explains concepts Claude already knows (no preamble about what GraphML or vis.js is) and instructions are direct. Minor trimming is possible: the visibility-filter rules are fully stated in the "Visibility Filter" section and then repeated in Step 1, and the community color palette appears twice in section 3d. This fits the 4 anchor (efficient with minor instances that could be trimmed) rather than 5's every-token-earns-its-place.

Actionability

Guidance is fully executable: exact glob exclusions, the wikilink regex `\[\[.*?\]\]`, link normalization rules, confidence overrides, complete worked examples for all four output formats, and a copy-paste-ready HTML template with explicit placeholder substitution instructions. This matches the 5 anchor's copy-paste-ready coverage of common cases.

Workflow Clarity

The sequence is clear and well-numbered (pre-flight checks, build node/edge lists, assign communities, write four outputs, print summary) and includes a pre-flight checkpoint ("if fewer than 5 pages exist, warn the user and stop") plus a count-reporting summary. It falls short of the 5 anchor because there is no post-write validation or feedback loop verifying the output files were written correctly.

Progressive Disclosure

Sections are well-organized and easy to navigate (Before You Start, Steps 1-4 with sub-sections 3a-3d, Notes), and the skill has no bundle files so all guidance is legitimately inline. However, the ~60-line HTML template inlined in the body is content that could live in an assets/ template file, which keeps this at the 4 anchor (good structure, minor organization gaps) rather than 5.

Specificity

The description names the domain, four concrete output formats (graph.json, graph.graphml, cypher.txt, graph.html), the target tools (Gephi, Neo4j), and the exact output destination (wiki-export/ at the vault root). This matches the 5 anchor's comprehensive coverage of specific concrete actions; it exceeds 4 because there are no meaningful gaps in what is produced and where.

Completeness

It explicitly answers both questions: the "what" is exporting the Obsidian wiki's knowledge graph to four named structured formats, and the "when" is a full "Use this skill when the user says..." clause with concrete trigger phrases. This matches the 5 anchor exactly; it is above 4 because the "when" is explicit and specific, not merely present.

Trigger Term Quality

It lists eight explicit natural trigger phrases ("export wiki", "export to Gephi", "visualize wiki", "knowledge graph export", etc.) plus a general condition ("wants to use their wiki data in another tool"), giving good coverage. It stops short of the 5 anchor because a few natural terms and file extensions are absent (e.g., "Obsidian export", "export notes", ".graphml" as a trigger).

Distinctiveness Conflict Risk

The Obsidian wikilink-graph export niche is clear and the triggers (graphml, Neo4j, Gephi, wiki export) are distinct from generic file- or document-handling skills, so conflict risk is minimal. It matches the 5 anchor's "clear niche with distinct triggers".
