Conciseness

The body is lean and assumes Claude's competence — it never explains what Obsidian or mkdir is, keeps directory notes to informative one-liners ("_raw/ — Staging area for unprocessed drafts... wiki-ingest will promote them"), and defers QMD install detail to ".env.example". Every token earns its place, matching the lean anchor rather than the minor-trimming anchor 4.

Actionability

Fully executable throughout: an exact "mkdir -p" command with brace expansion, complete copy-paste templates for index.md, log.md, and hot.md, full .obsidian JSON configs, and concrete user questions with defaults and fallbacks. Clearly-marked placeholders (TIMESTAMP, OBSIDIAN_VAULT_PATH) make it copy-paste ready, matching the top anchor.

Workflow Clarity

Steps 1-6 are clearly sequenced and Step 6 provides an explicit verification checklist with report-back and next actions. It falls short of anchor 5 because there is no error-recovery feedback loop — no guidance on what to do if a sanity check fails — and it is above anchor 3 since the validation checkpoint is explicit rather than implicit.

Progressive Disclosure

Well-organized self-contained sections with sensible deferral of detail to .env.example, and no nested or buried references. At ~153 lines it exceeds the under-50-line threshold where sections alone merit a 5, and the three file templates could arguably live in assets/ files to copy rather than retype, placing it at the good-structure-with-minor-gaps anchor.

Specificity

Lists several actions — "Initialize a new Obsidian wiki vault with the correct structure, special files, and configuration", "create the .env file", "reconfigure their existing vault", "fix a broken setup" — matching the several-specific-actions anchor. It falls short of 5 because "special files" and "configuration" are unnamed abstractions rather than concrete enumerations, and above 3 since more than 1-2 actions are given.

Completeness

Explicitly answers "what" ("Initialize a new Obsidian wiki vault with the correct structure, special files, and configuration") and "when" with a literal "Use this skill when..." clause containing concrete trigger phrases, plus a secondary "Also use when" clause for reconfiguration/repair. Matches the both-what-and-when-with-concrete-triggers anchor exactly; not 4 because the "when" is fully explicit rather than merely present.

Trigger Term Quality

Quotes natural user phrases — "set up my wiki", "initialize obsidian", "create a new vault", "get started with the wiki" — plus "from scratch", "reconfigure", and "fix a broken setup", covering the synonym space (set up / initialize / create / get started). Not 4: coverage is comprehensive for this domain, where no file extensions meaningfully apply.

Distinctiveness Conflict Risk

Occupies a clear niche (Obsidian wiki vault initialization and repair) with distinct quoted triggers unlikely to fire for sibling skills. The "fix a broken setup" clause slightly broadens scope but stays within this skill's stated purpose, so it does not drop to the minor-overlap anchor 4.
