commitlayer-integrations (Python)

CommitLayer for agent frameworks and durable-workflow runtimes. One distribution, six optional packages, built on the commitlayer SDK:

The four framework packages share one mapping and one recorder (commitlayer_integrations.tools.ToolRecorder): a tool name maps to a contract, the argument that holds the subject, and the arguments that are the action's parameters, in the same shape the MCP recorder's mapping file uses. Each framework package is the hook at which that recorder runs: a wrap_tool_call wrapper for LangGraph, a before_tool_call hook for CrewAI, RunHooks for the OpenAI Agents SDK, a WrapperToolset for Pydantic AI. None of them imports its framework at module load, so the tests run without any of them installed.

Each one does the same two things in its runtime's own terms:

1. Record the agent's intent before the work runs (an activity, a step) as an action under a contract: POST /v1/actions with the contract, subject and parameters taken from the call's own arguments. The result of the work is never sent.
2. Gate completion on the verdict: wait for GET /v1/actions/{ref} to report a settled verification and branch on PASS / FAIL / UNKNOWN. The workflow does not tell the customer "done" until the verdict is PASS.

The workflow engine makes the process durable. CommitLayer independently verifies the result, from the systems of record, after the fact. The agent may declare its intent. It may read the verdict. It must never control the independent facts, the governing contract, or the final evidence.

Python 3.10+. Both packages import without their runtime SDK installed (the SDK is imported lazily), so a service that uses only one of them does not need the other.
