# Troubleshooting Skill Matrix Router This router coordinates the four-skill core: 1. `troubleshooting-skill-matrix`: this router. 2. `agent-error-memory`: records agent-caused execution or process errors. 3. `bug-solution-memory`: records practical solutions and validation paths. 4. `shared-semantic-anchors`: records user-confirmed meanings and boundaries. `embedded-harness` is an adjacent low-cost intake, memory-isolation, external-research, claim-gate, and selective-enforcement layer. It is not a fifth core skill. ## Invocation Use this router when a task involves: - recording or retrieving a reusable incident; - updating an error/solution memory pair; - semantic anchor definitions; - project router manifest design; - external mechanism intake; - deciding whether an existing skill/tool/plugin should be used. ## Retrieval Workflow ```text request -> read memory_summary / _META_INDEX / router manifest first -> scan the compact point index -> select matching ERR/SOL/anchor by retrieval surface -> read only the selected payload -> apply to the current task ``` If no meta layer exists yet, use this router manifest and the compact point index as the temporary meta layer. Do not scan every point payload before choosing by retrieval surface. ## Mandatory Advisory Control Plane Use this router under the required advisory control plane: ```text routing receipt -> select the smallest needed router/skill/memory surface -> event-triggered re-evaluation after trigger events
