Struct BuiltinTool 

pub struct BuiltinTool {
    pub name: String,
    pub display_name: Option<String>,
    pub description: String,
    pub parameters: Value,
    pub policy: ToolPolicy,
    pub category: Option<String>,

    pub full_parameters: Option<Value>,

Built-in tool configuration

Note: The kind field has been removed. Tools are now identified solely by their name field, and execution happens via the ToolRegistry which looks up tools by name.

Fields

name: String

Tool name (used by LLM and for registry lookup)

display_name: Option<String>

Human-readable display name for UI rendering (e.g., “Get Current Time” for get_current_time)

description: String

Tool description for LLM

parameters: Value

JSON schema for tool parameters

policy: ToolPolicy

Tool policy (auto or requires_approval)

category: Option<String>

Category for tool_search namespace grouping (from parent capability)

deferrable: DeferrablePolicy

Whether this tool’s schema can be deferred via tool_search

hints: ToolHints

Semantic hints describing the tool’s behavioral properties

full_parameters: Option<Value>

Original full parameter schema saved by DeferSchemaHook before stripping. Serialized only when present so durable reason-to-act scheduling can preserve deferred schemas for tool_search in the act phase.
