20	Environment Variables	Environment Variables

Goose supports various environment variables that allow you to customize its behavior. This guide provides a comprehensive list of available environment variables grouped by their functionality.

Model Configuration

These variables control the language models and their behavior.

Basic Provider Configuration

These are the minimum required variables to get started with Goose.

Variable	Purpose	Values	Default
GOOSE_PROVIDER	Specifies the LLM provider to use	See available providers	None (must be configured)
GOOSE_MODEL	Specifies which model to use from the provider	Model name (e.g., "gpt-4", "claude-3.5-sonnet")	None (must be configured)
GOOSE_TEMPERATURE	Sets the temperature for model responses	Float between 0.0 and 1.0	Model-specific default

Examples

# Basic model configuration
export GOOSE_PROVIDER="anthropic"
export GOOSE_MODEL="claude-3.5-sonnet"
export GOOSE_TEMPERATURE=0.7

Advanced Provider Configuration

These variables are needed when using custom endpoints, enterprise deployments, or specific provider implementations.

Variable	Purpose	Values	Default
GOOSE_PROVIDER__TYPE	The specific type/implementation of the provider	See available providers	Derived from GOOSE_PROVIDER
GOOSE_PROVIDER__HOST	Custom API endpoint for the provider	URL (e.g., "https://api.openai.com")	Provider-specific default
GOOSE_PROVIDER__API_KEY	Authentication key for the provider	API key string	None

Examples

# Advanced provider configuration
export GOOSE_PROVIDER__TYPE="anthropic"
export GOOSE_PROVIDER__HOST="https://api.anthropic.com"
export GOOSE_PROVIDER__API_KEY="your-api-key-here"
## Planning Mode Configuration

These variables control Goose's [planning functionality](/docs/guides/creating-plans).

| Variable | Purpose | Values | Default |
|----------|---------|---------|---------|
| `GOOSE_PLANNER_PROVIDER` | Specifies which provider to use for planning mode | [See available providers](/docs/getting-started/providers#available-providers) | Falls back to GOOSE_PROVIDER |
| `GOOSE_PLANNER_MODEL` | Specifies which model to use for planning mode | Model name (e.g., "gpt-4", "claude-3.5-sonnet")| Falls back to GOOSE_MODEL |

**Examples**

```bash
# Planning mode with different model
export GOOSE_PLANNER_PROVIDER="openai"
export GOOSE_PLANNER_MODEL="gpt-4"

Tool Configuration

These variables control how Goose handles tool permissions and their execution.

Variable	Purpose	Values	Default
GOOSE_MODE	Controls how Goose handles tool execution	"auto", "approve", "chat", "smart_approve"	"smart_approve"
GOOSE_TOOLSHIM	Enables/disables tool call interpretation	"1", "true" (case insensitive) to enable	false
GOOSE_TOOLSHIM_OLLAMA_MODEL	Specifies the model for tool call interpretation	Model name (e.g. llama3.2, qwen2.5)	System default
GOOSE_CLI_MIN_PRIORITY	Controls verbosity of tool output	Float between 0.0 and 1.0	0.0

Examples

# Enable tool interpretation
export GOOSE_TOOLSHIM=true
export GOOSE_TOOLSHIM_OLLAMA_MODEL=llama3.2
export GOOSE_MODE="auto"
export GOOSE_CLI_MIN_PRIORITY=0.2  # Show only medium and high importance output

## Security Configuration

These variables control security related features.

| Variable | Purpose | Values | Default |
|----------|---------|---------|---------|
| `GOOSE_ALLOWLIST` | Controls which extensions can be loaded | URL for [allowed extensions](/docs/guides/allowlist) list | Unset |
| `GOOSE_DISABLE_KEYRING` | Disables the system keyring for secret storage | Set to any value (e.g., "1", "true", "yes") to disable. The actual value doesn't matter, only whether the variable is set. | Unset (keyring enabled) |

:::tip
When the keyring is disabled, secrets are stored here:

* macOS/Linux: `~/.config/goose/secrets.yaml`
* Windows: `%APPDATA%\Block\goose\config\secrets.yaml`
:::


## Langfuse Integration

These variables configure the [Langfuse integration for observability](/docs/tutorials/langfuse).

| Variable | Purpose | Values | Default |
|----------|---------|---------|---------|
| `LANGFUSE_PUBLIC_KEY` | Public key for Langfuse integration | String | None |
| `LANGFUSE_SECRET_KEY` | Secret key for Langfuse integration | String | None |
| `LANGFUSE_URL` | Custom URL for Langfuse service | URL String | Default Langfuse URL |
| `LANGFUSE_INIT_PROJECT_PUBLIC_KEY` | Alternative public key for Langfuse | String | None |
| `LANGFUSE_INIT_PROJECT_SECRET_KEY` | Alternative secret key for Langfuse | String | None |


## Notes

- Environment variables take precedence over configuration files.
- For security-sensitive variables (like API keys), consider using the system keyring instead of environment variables.
- Some variables may require restarting Goose to take effect.
- When using the planning mode, if planner-specific variables are not set, Goose will fall back to the main model configuration.
