We welcome Pull Requests for general contributions. If you have a larger new feature or any questions on how to develop a fix, we recommend you open an [issue][issues] before starting.
Developers can use locally hosted Langfuse tracing by applying the custom `observe_wrapper` decorator defined in `packages/exchange/src/exchange/observers` to functions for automatic integration with Langfuse, and potentially other observability providers in the future.
- Run `just langfuse-server` to start your local Langfuse server. It requires Docker.
- Go to http://localhost:3000 and log in with the default email/password output by the shell script (values can also be found in the `.env.langfuse.local` file).
- Run Goose with the --tracing flag enabled i.e., `goose session start --tracing`
`To extend tracing to additional functions, import `from exchange.observers import observe_wrapper` and use the `observe_wrapper()` decorator on functions you wish to enable tracing for. `observe_wrapper` functions the same way as Langfuse's observe decorator.
In case locally hosted Langfuse doesn't fit your needs, you can alternatively use other `observer` telemetry plugins to ingest data with the same interface as the Langfuse integration.
To do so, extend `packages/exchange/src/exchange/observers/base.py:Observer` and include the new plugin's path as an entrypoint in `exchange`'s `pyproject.toml`.
In the meantime, we typically incubate any new additions that change the behavior of the Goose through **opt-in** plugins - `Toolkit`s, `Moderator`s, and `Provider`s. We welcome contributions of plugins that add new capabilities to *goose*. We recommend sending in several examples of the new capabilities in action with your pull request.
