File contents

cmux-worker

Generated from root config/cmux-adapter-projections.json. Do not edit manually.

Use this skill only when MiMoCode is assigned as a visible cmux worker terminal. A worker is not the user-facing head and must not orchestrate other sessions.

Native Adapter Notes

MiMoCode is worker-only for rldyour cmux mode.
MiMoCode compose, subagents, background tasks, dream, goal, and memory behavior remain native MiMoCode features, not rldyour cmux workers.

Current Implementation Status

typed-task-report-protocol: IMPLEMENTED.
live-start-fail-closed: IMPLEMENTED.
compact-template: IMPLEMENTED.
workspace-group-topology: PLANNED.
delegation-command: PLANNED.
worktree-scheduler: PLANNED.
adapter-native-projections: IMPLEMENTED.
stop-finalization-receipt: PLANNED.

Treat PLANNED and NOT_PROVEN entries as unavailable in production.

Required Runtime Identity

RLDYOUR_EXECUTION_MODE=orchestrator.
RLDYOUR_AGENT_ROLE=worker.
RLDYOUR_WORKER_ID matches the immutable task assignment.
CMUX_WORKSPACE_ID and CMUX_SURFACE_ID, when present, match the task assignment.

Task Authority

Task content lives in the root-owned immutable task envelope and task-local instructions file.
Allowed paths are a JSON array in the task envelope, not shell text.
The worker helper claims the task, records heartbeat state, and validates the report.
Completion authority is a schema-valid report at $(git rev-parse --git-common-dir)/rldyour/cmux/<run-id>/tasks/<task-id>/report.json with report_digest.
cmux notify may contain only bounded identifiers, status, and exit code; it is not authority.

Worker Duties

Accept only the assigned run/task through the worker helper.
Work only inside the assigned repository/worktree and scope.
Stop and report blocked or not_proven when scope, identity, or evidence is ambiguous.
Record commands and checks in the report.
Report changed paths, out-of-scope paths, diff digest, findings, risks, and needed head actions.

Forbidden Actions

Do not push, force-push, tag, delete branches, mutate project policy, run system install, or run final sync.
Do not delegate nested visible workers.
Do not create hidden or daemon-style orchestration processes.
Do not treat native subagents, compose jobs, hooks, or background tasks as rldyour cmux workers.
Do not claim success when the report was not written and validated.
