Handoff Workbench makes authority transfer between AI agents explicit, reviewable, and verifiable. A human sees the exact proposed scope, approves its digest, and can follow the handoff through a versioned lifecycle to a verified completion receipt.
Open the live synthetic Workbench
- Signed handoff envelopes with explicit recipient, capability, resource, data, money, evidence, and expiration bounds
- Exact digest-bound human approval before delegation advances
- A seven-step lifecycle with seven ordered durable events at completion
- Receipt verification and durable recovery after reload
- Stable rejection codes with no state change for demonstrated authority expansion, wrong-recipient, stale-version, replay, and tampering attacks
- A narrow MCP tool boundary for programmatic integration
The supplied scenario is synthetic. It does not represent customer adoption, production financial authority, unsupervised operation, or live-network rate exhaustion.
Requirements: Node.js 24.12.x and npm 11.6.x.
npm ci
npm test
npm run workbenchOpen http://127.0.0.1:4188/. The documented command starts the interface and its real local application service on one same-origin listener. SQLite state is stored under .workbench-local/ unless WORKBENCH_DB_PATH is set.
