Goose (Block)

Trace Block's Goose AI agent in Muster via env var configuration.

Goose is Block's open-source AI developer agent. Muster (langfuse) tracing is configured via environment variables — once set, every Goose action is captured.

Setup

1. Get Muster API keys

Sign up at your Muster instance (or self-host) and copy the public/secret keys.

2. Set environment variables

export LANGFUSE_INIT_PROJECT_PUBLIC_KEY="pk-lf-..."
export LANGFUSE_INIT_PROJECT_SECRET_KEY="sk-lf-..."
export LANGFUSE_HOST="https://app.getmuster.io"

3. Run Goose

Start Goose with the env vars set. Muster begins capturing traces of every LLM call and agent action.
