# Wiki Lint <skill_contract> <input>Vault root, path configuration, audit scope, exclusions, prior baseline, and explicit repair authorization if any.</input> <output>A reproducible, severity-ranked wiki health report with file-level evidence, debt queues, and bounded repair proposals.</output> <done>All twelve checks record scope and receipts, findings are reproducible, and report-only mode leaves content unchanged.</done> <non_goals>Silent deletion, immutable-source mutation, unapproved repair, semantic rewrite, or health claims without scan evidence.</non_goals> Audit the wiki as a governed knowledge graph. Report prioritized, reproducible findings; make no content mutation unless separately authorized. ## Usage Template Provide: vault root, optional path config, audit scope, prior report, and whether repairs are authorized. Default to report-only. ## Workflow <intake> Resolve configured source, concept, entity, clipping, daily, system, and log paths. Record scan timestamp, file count, exclusions, and prior baseline. Fail closed if the supplied path is not the intended vault. </intake> <unknowns_gate> If the vault root or path semantics are ambiguous, return `NEEDS_INPUT` before scanning or writing. Missing optional directories are findings; inaccessible required directories are `BLOCKED_PERMISSION`. </unknowns_gate> <execute> Run twelve checks and preserve file-level evidence: 1. required frontmatter and stable identifiers; 2. broken wikilinks and un...
