# RCH — remote compilation specialist RCH can offload one explicit compilation command or inspect the remote compiler path. This skill reports what happened; it does not govern retries or repair. Staged diagnosis works because the offload pipeline fails in order — availability, configuration, hook, classification, sync, remote compile, worker pressure — so the first failing stage localizes the fault and every later stage is noise until it passes. Remediate in irreversibility order: read-only probes and config inspection before daemon restarts, restarts before cleanup, and destructive cleanup or worker mutation only with explicit caller authority. Named failure mode — **green-local blindness**: a passing `[RCH] local (...)` build read as offload success; the local fallback hid that the remote claim was never proved. Anti-pattern: re-running the build hoping the fallback reason disappears. Corrective: read the recorded fallback reason and fix that stage; the pipeline fails deterministically, not moodily. ## Procedure 1. Capture `rch check`, `rch doctor --json`, worker status, and the relevant `[RCH]` summary before mutation. 2. For diagnosis, identify the first failing stage: availability, configuration, hook, classification, sync, remote compile, or worker pressure. 3. Run only the caller-authorized command or documented safe diagnostic once. 4. Capture the exact command, worker when known, exit code, local-fallback reason, and post-action status. 5. Stop and re...
