Global scenario configuration with per-test overridable fields.

Fields

base_url: Option<String>

Base URL for relative navigation.

llm_url: Option<String>

LLM server base URL (deprecated; prefer [config.endpoints]).

llm_model: Option<String>

LLM model name (deprecated; prefer [config.endpoints]).

llm_api_key: Option<String>

LLM API key (Bearer token).

llm_headers: HashMap<String, String>

Custom HTTP headers as JSON key-value pairs.

browser_headless: Option<bool>

Run browser in headless mode.

timeout_secs: Option<u64>

HTTP / browser action timeout in seconds.

viewport_width: Option<u32>

Browser viewport width.

viewport_height: Option<u32>

Browser viewport height.

start_url: Option<String>

Default URL every test auto-navigates to before running its steps.

auto_navigate: bool

Whether to auto-navigate to start_url before test steps.

Disable when a test starts with click-based navigation.

temperature: f64

LLM temperature (0.0–1.0). Lower = more deterministic.

thinking: Option<bool>

Enable thinking/reasoning tokens. None means the provider default is used (no thinking key is sent). Set to true/false to explicitly enable or disable.

model_params: HashMap<String, Value>

Provider-specific model parameters merged into the chat completion request body (e.g. effort = "high" for Anthropic).

endpoints: HashMap<String, EndpointConfig>

Named endpoints (LLM, MCP, A2A agents) with pricing.

budgets: BudgetsConfig

Global and per-test budgets for cost/token/call limits.

mcp_server: Option<McpServerConfig>

MCP server exposure configuration.

a2a_server: Option<A2aServerConfig>

A2A agent server exposure configuration.
