Connect Your Agent to LangWatch Simulations

Connect the agent in this codebase to LangWatch, so test suites run from the platform against the real agent process. The SDK opens an outbound connection to LangWatch from the process that already runs the agent, registers the agent with its environment and its run parameters, and receives one call per conversation turn. The simulation exercises the real code, dependencies, secrets and traces.

Three steps: install the SDK, add the connect function where the service starts, start the service the way the user always starts it. Work through them in order, confirm the agent reads Online, run one test suite, then report what changed and the result.

In Langy, do not print the change for the user to apply by hand: call code_access and follow the code-changes skill to make it on their machine or through GitHub.

Use the HTTP fallback at the bottom of this skill ONLY when the agent cannot import the SDK: the agent is written in a language with no LangWatch SDK, or you have no access to its code.

Step 1: Set up the LangWatch CLI
