Avoid orchestrator-budget burn when a subagent's main work is done but it's still polling an external event (CI completion, auto-deploy GHA workflow, Cloud Build, gcloud run revision rollout, long-running test suite, etc.). Use when: (1) you've dispatched a subagent with a final-step instruction like "verify auto-deploy" / "wait for CI green" / "poll until revision active", (2) the subagent has already done its substantive work (PR merged, artifact built) and is now in a polling loop, (3) you…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Subagent external-wait → orchestrator-takeover ## Problem You dispatch a subagent with a brief that includes both substantive work AND a final verification step gated on an external event: > "1. Implement … 2. Open PR … 3. Merge … 4. **Verify auto-deploy: poll GHA > workflow + `gcloud run revisions list` until new revision is active.**" Step 4 is **wait work** — the subagent has nothing to compute, only to wait and check. The harness keeps the agent task open during this wait, and each heartbeat / external signal wakes the agent for a tiny no-op cycle: ``` status: completed · tool_uses: 0 · duration_ms: 2000 · result: "Still polling." status: completed · tool_uses: 0 · duration_ms: 2200 · result: "In progress." status: completed · tool_uses: 0 · duration_ms: 1800 · result: "Continuing to wait." ... × 10-20 ... ``` Each cycle costs: - **Subagent**: ~100-300 tokens of additional context per wake (small but accumulates) - **Orchestrator**: ~one full turn to acknowledge the notification (large — the orchestrator's context is bigger and every reply costs) The orchestrator's response cost dwarfs the subagent's polling cost. Over a …

How to install
mdr add wan-huiyan/agent-traffic-control/subagent-external-wait-orchestrator-takeover@sha256:1274afa4af5b797dThe line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
