impl Tool for WebFetchTool

fn definition(&self) -> ToolDef

fn approval(&self, args: &str) -> ApprovalRequirement

fn execute<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, args: &'life1 str, _ctx: &'life2 ToolContext, ) -> Pin<Box<dyn Future<Output = Result<ToolResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

fn approval_with_context( &self, args: &str, _ctx: &ToolContext, ) -> ApprovalRequirement

fn validate_args(&self, _args: &str) -> Result<(), String>

Pre-flight syntactic check on raw tool-call arguments. The runner calls this before approval and before execute, so a parse failure short-circuits to a tool-result error and the model receives a structured retry hint without bothering the user.
