Open protocol infrastructure for cooperative industrial machine agents.
CAP defines transport-neutral communication semantics between a Site Agent and Machine Agents operating shared industrial resources. The project focuses on auditable coordination, typed handover, conformance testing, and reproducible protocol-level experiments for autonomous earthwork fleets and adjacent domains.
- A protocol specification for manifests, work orders, heartbeats, dialogue, entity descriptors, reservations, handover, and structured errors.
- A safety boundary that keeps deterministic safety supervision and machine control independent from LLM-based planning and advisory layers.
- Reference SDKs, agents, conformance tests, and public reproduction packages for the protocol-level results reported in the CAP paper.
- Model-checked coordination logic for shared-resource arbitration and typed machine-to-machine handover.
| Repository | Role | Start here |
|---|---|---|
cap-spec |
Protocol Buffers, formal specification, ADRs, RFCs, examples, and TLA+ models. | Read the protocol overview and generated message structure. |
cap-reference |
Python SDK, reference agents, simulator adapters, and TypeScript/C++ interop surfaces. | Run the minimal Machine Agent and inspect the gRPC runtime. |
cap-conformance |
L1/L2/L3 conformance suite covering core runtime behavior, coordination, dialogue, security, and interop. | Use the pytest suite to validate an implementation. |
cap-coordination-kit |
Public protocol-logic kit for reservation arbitration, typed handover, operational-P4 models, and refinement monitoring. | Reproduce the open coordination invariants. |
cap-bench |
Offline reproduction package for fault-injection and fleet-size benchmark campaigns. | Run smoke campaigns or full paper-scale sweeps. |
CAP is designed to be machine-agnostic, transport-neutral, and safety-independent. It is meant to standardize the coordination layer without claiming ownership of low-level control, perception, emergency stop, or OEM-specific safety systems.
The current public repos are released under Apache-2.0 and are organized around independent implementation, conformance, and reproduction.
