Goose

Goose is Block’s open-source agent. It supports OpenAI-compatible providers via configuration.

Configure

Edit ~/.config/goose/config.yaml:

GOOSE_PROVIDER: openai
OPENAI_HOST: https://lowrouter.ai/api/v1
OPENAI_API_KEY: lr-sk-...
GOOSE_MODEL: lowrouter/auto

Or set them as environment variables before starting Goose:

export GOOSE_PROVIDER=openai
export OPENAI_HOST=https://lowrouter.ai/api/v1
export OPENAI_API_KEY=lr-sk-...
export GOOSE_MODEL=lowrouter/auto
goose session

Picking a model

Set GOOSE_MODEL to any LowRouter model ID. For agentic tasks (file reading, shell tools, multi-step reasoning), pick a model tagged with tool_use: true on the model browser.

Recommended setup

• Dedicated key, daily limit. Same reasoning as the other agents: agentic loops can run away.
• Limit the toolset Goose has access to. Goose’s extensions config lets you allow only the tools the workflow needs. Fewer enabled tools = fewer surprises.
• Set a step limit. Goose has a max-step setting; cap it at a small number for unattended runs.

Troubleshooting

• Goose immediately exits with a config error: OPENAI_HOST does not include a trailing slash. Match the value above exactly.
• Tool calls fail silently: verify the chosen model actually supports tool use (model browser, tool_use: true). Some smaller models don’t.
