reeve-sdk

The Python SDK for Reeve, a terminal cockpit for AI agents: watch a live trace tree, score every step, and pause, redirect, or stop an agent while it runs.

from reeve_sdk import CheckpointResult, ReeveSdk

sdk = await ReeveSdk.connect("my-agent")

@sdk.trace()
async def run():
    while not done:
        result = await sdk.checkpoint()  # pauses here if you command it to
        if isinstance(result, CheckpointResult.Redirect):
            steer_toward(result.instruction)
        response = await llm.invoke(messages)

Adapters ship for LangChain (ReeveCallbacks), the OpenAI Agents SDK (ReeveHooks), and the Claude Agent SDK (ReeveClaudeClient); each wires checkpoint() and OpenTelemetry spans into the framework's own lifecycle. The cockpit itself installs with cargo install reeve-cockpit.
