Relay Sidecar

relay-sidecar is an ADVISORY AUXILIARY skill for existing relay runs. It is NOT part of the mandatory plan → dispatch → review → merge lifecycle, and /relay does not require a sidecar step.

Use when

• Running an artifact-only advisory sidecar for an existing relay run
• Capturing supplemental context recap, test-gap, docs-sync, or similar output
• Producing non-gating sidecar artifacts under a run's sidecars/<id>/ directory

Do not use when
