awp-python

The Python agent SDK for the Agent World Protocol. ClientConnection is the agent side of AWP as a sans-IO state machine, and awp.aio.AsyncClient drives it over a WebSocket.

It targets specification revision 0.1-draft.12, pinned as the spec/ submodule. This is an alpha, so the API will change along with the draft. The reference world, awp-sim, is a separate package built on this one.

Status

In both time models, the demo agent built on the client is Core Agent: AWP-conformant against 0.1-draft.12. awp-conformance reports no failure and nothing untested, and conformance/ holds the reports and the evidence for their manual rows.

Implemented:

• lockstep and streaming sessions, with world.tick advances that wait for every per-tick channel;
• multi-bind sessions (embodiments);
• inline and ws stream bindings, and the binary frame codec (every spec vector);
• the action lifecycle, checked against the spec's transition table, and idempotent resubmission;
• heartbeats, clock synchronization, receiver reports, and resumption with replay and acknowledgement;
• canonical schema validation in receiver and sender forms;
• task, approval and standing approvals, transfer, reset, snapshots, and command channels.

Not implemented: stream bindings other than inline and ws (webrtc, webtransport, shm, grpc).

Install

pip install --pre awp-python

Requires Python 3.11+.

Using the client

With asyncio:

from awp import ClientConnection
from awp.aio import AsyncClient

conn = ClientConnection({"name": "my-agent", "version": "0.1.0", "vendor": "me"}, ["proprio/json"])
async with AsyncClient(conn, "ws://127.0.0.1:8710") as client:
    await client.initialize()
    await client.open_session("streaming", embodiment="arm_01", subscribe=["proprio"])
    await client.wait_for(lambda e: "proprio" in client.latest)
    record = await client.submit(
        "move_to_pose",
        {"pose": {"frame": "base", "p_m": [0.3, 0.2, 0.5], "q": [0, 0, 0, 1]}},
        basis=client.latest["proprio"].frame,  # the observation this intent rests on
        valid_for_ms=200,
    )
    print((await client.wait_terminal(record.action_id)).state)
    await client.close_session()

Without asyncio, feed ClientConnection the decoded messages and send whatever it queues:

from awp import jsonrpc

events = conn.receive(jsonrpc.decode(text))  # typed events: ActionUpdated, FrameReceived, ...
for out in conn.outgoing():  # messages to send, in order
    transport.send(jsonrpc.encode(out))

The connection:

• tracks the action lifecycle against the spec's transition table;
• deduplicates replayed statuses;
• keeps the clock offset from heartbeats;
• reports any violation by the world as a ProtocolViolation event.

The demo agent

awp-demo is a scripted agent for awp-sim's arm. It moves, cancels a move, and triggers an envelope refusal. It rides out a lost connection by resuming the session, or by opening a new one if the world no longer holds it.

pip install --pre awp-sim
awp-sim serve &                      # streaming world on ws://127.0.0.1:8710
awp-demo                             # or --url, --token ($AWP_URL, $AWP_TOKEN)
