Struct ManagedBuiltinTool 

pub struct ManagedBuiltinTool { /* private fields */ }

Built-in tool for server-side execution (bash, filesystem, web_search, etc.).

When the Runner calls execute(), this tool performs the operation in-process. For bash, it spawns a child process via tokio::process::Command. For tools that require external services (web_search, web_fetch), it returns a structured error indicating the service is unavailable unless explicitly configured.

When a sandbox backend is configured, execution tools (bash, code_execution) delegate to the sandbox for isolated execution instead of running in-process.

Implementations

impl ManagedBuiltinTool

pub fn new(name: impl Into<String>, description: impl Into<String>) -> Self

Create a new built-in tool (no sandbox).

Trait Implementations

impl Clone for ManagedBuiltinTool

fn clone(&self) -> ManagedBuiltinTool

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ManagedBuiltinTool

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Tool for ManagedBuiltinTool

fn name(&self) -> &str

Returns the unique name of this tool.

fn description(&self) -> &str

Returns a human-readable description of what this tool does.

fn execute<'life0, 'async_trait>( &'life0 self, _ctx: Arc<dyn ToolContext>, args: Value, ) -> Pin<Box<dyn Future<Output = Result<Value>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Executes the tool with the given context and arguments.

fn declaration(&self) -> Value

Returns the tool declaration that should be exposed to model providers.

fn enhanced_description(&self) -> String

Returns an enhanced description that may include additional notes. For long-running tools, this includes a warning not to call the tool again if it has already returned a pending status. Default implementation returns the base description.

fn is_long_running(&self) -> bool

Indicates whether the tool is a long-running operation. Long-running tools typically return a task ID immediately and complete the operation asynchronously.

fn is_builtin(&self) -> bool

Indicates whether this tool is a built-in server-side tool (e.g., google_search, url_context).

fn parameters_schema(&self) -> Option<Value>

Returns the JSON Schema for this tool’s parameters, if any.

fn response_schema(&self) -> Option<Value>

Returns the JSON Schema for this tool’s response, if any.

fn required_scopes(&self) -> &[&str]

Returns the scopes required to execute this tool.

fn is_read_only(&self) -> bool

Indicates whether this tool performs no side effects. Read-only tools may be executed concurrently in Auto mode.

fn is_concurrency_safe(&self) -> bool

Indicates whether this tool is safe for concurrent execution. Used by the Parallel strategy to validate dispatch safety.
