What problem does it solve? Lens knowledge topologies accumulate defects like duplicate stable IDs, broken parent links, and stale metadata that silently block projection rebuilds. This Skill runs read-only health checks that separate blocking defects from advisory warnings and tell you exactly which workflow can fix each finding. ## Core Features & Use Cases - Blocking Defect Detection: Identifies duplicate published stable IDs, missing required metadata, invalid ID prefixes, broken belongs_to references, parent cycles, and broken local links. - Advisory Triage: Flags draft parent gaps, unpromoted completed knowledge, Salmon signals, and stale timestamps that do not block projections. - Workflow Routing: Produces a compact doctor report with JSON output and routes each finding to the owning workflow such as lens-topology-design, lens-ledger-promotion, or lens-salmon-impact. - Use Case: Before rebuilding published projections, run a doctor check to confirm no blocking defects exist, then follow the routing guidance to resolve any findings. ## Quick Start Ask the assistant to run lens doctor against the project to check topology health and report any blocking or advisory findings.
