Struct UrlContextTool 

pub struct UrlContextTool;

Available on crate feature tools only.

UrlContext is a built-in tool that is automatically invoked by Gemini models to fetch and analyze content from URLs. The tool operates internally within the model and does not require or perform local code execution.

impl UrlContextTool

pub fn new() -> UrlContextTool

Trait Implementations

impl Default for UrlContextTool

fn default() -> UrlContextTool

Returns the “default value” for a type.

impl Tool for UrlContextTool

fn name(&self) -> &str

fn description(&self) -> &str

fn is_builtin(&self) -> bool

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

fn declaration(&self) -> Value

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

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

where 'life0: 'async_trait, UrlContextTool: 'async_trait,

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 parameters_schema(&self) -> Option<Value>

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

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.
