Expand description

Metadata sent by clients (CLI, browser SDK, etc.) alongside A2A messages. Deserialized by the server to configure execution context. This is the canonical schema — all clients should serialize this struct.

Fields§

§tool_metadata: Option<HashMap<String, Value>>

Additional context for tools to use, passed as meta in tool calls

§metadata: Option<Value>§additional_attributes: Option<AdditionalAttributes>§external_tools: Option<Vec<ExternalTool>>

External tools that delegate execution to the client

§definition_overrides: Option<DefinitionOverrides>

Definition overrides supplied by the client

§dynamic_sections: Option<Vec<PromptSection>>

Dynamic prompt sections to inject into the template per-call

§dynamic_values: Option<HashMap<String, Value>>

Dynamic key-value pairs available in templates per-call

§browser_session_id: Option<String>

Browser session ID for browser tool integration

§env_vars: Option<HashMap<String, String>>

Environment variables passed from the client for execution

§dry_run: Option<bool>

When true, unsafe tools are simulated via LLM instead of executed

§runtime_mode: RuntimeMode

Runtime environment. Determines which system agent variants to use.
