Run a deterministic, read-only health check on an Obsidian wiki. Use for lint, vault health check, audit wiki health, find orphans, find dead links, frontmatter audit, provenance audit, or wiki audit. Reports graph, link, frontmatter, provenance-ledger, empty-section, and stale-index findings; it do

Lint the wiki Use the portable lint engine as the source of truth. Lint observes vault state; it does not create reports, dashboards, canvases, stubs, or fixes. Resolve the installed product root from this skill's own location, not from the vault or current working directory: Every ../wiki/references/ link in this file resolves the same way, relative to this skill's own directory under $PRODUCT ROOT , never relative to the selected vault's wiki/ directory. Run Resolve the user vault, then run one of: The repeatable exclude GLOB flag scopes a path (for example a scratchpad folder) out of page, link resolution, orphan, frontmatter, empty section, and stale index scanning. Use strict only when a nonzero exit for findings is useful in automation. The command remains read only either way. The deterministic parser understands Obsidian wikilinks and embeds, Markdown links, aliases, heading and block fragments, escaped aliases, and code fences. It skips dot prefixed directories by default, mirroring Obsidian's own indexer. Link resolution honors .gitignore files inside the vault (no git subprocess): when a link is ambiguous between a page and a gitignored file such as a build artifact, the gitignored candidate is dropped. It reports such categories as dead or ambiguous links, orphan pages, required frontmatter gaps (including title ), empty sections, stale index entries, and source/claim ledger contract violations. Report only the checks and counts present in its output; do not claim that it performed semantic, stylistic, or prose level contradiction analysis when it did not. Explain findings 1. Preserve the engine's paths, line numbers, targets, categories, and counts. 2. Group findings by likely impact: broken navigation, ambiguous resolution, metadata quality, then maintainability. 3. Explain that an orphan may be intentional and an ambiguous basename needs a path qualified link; do not infer intent from the finding alone. 4. Treat allowlisted findings as policy, not as proof that the target exists. 5. Separate deterministic facts from suggested remediation. Do not write the Markdown rendering into the vault. Return it in chat or stdout. Repair is a separate operation Never auto fix a lint result. After the user chooses specific findings to repair: 1. Re read each target and record its expected SHA 256. 2. Draft only the selected changes; do not delete or merge pages without explicit consent. 3. Build one repair bundle with a new operation ID. 4. Inspect the bundle and show exact changed paths. 5. Apply only after that separate review. 6. Re run lint read only and compare the relevant findings. Follow the [operation transaction contract](../wiki/references/operation transactions.md). Lint itself never applies that transaction and never commits Git. Checkpoint Observe the deterministic report, think about root causes rather than finding count, verify proposed repairs against current hashes, and grow by improving the workflow that produced repeated findings.
