Struct JsReplTool 

pub struct JsReplTool;

JavaScript REPL tool — executes JavaScript code using Node.js.

Uses a fresh Node.js subprocess per invocation. The code is piped to node --input-type=module on stdin so multi-line programs and await at the top level are supported.

Inspired by Codex’s js_repl tool but uses a simpler sub-process model rather than a persistent kernel.

Implementations

impl JsReplTool

pub fn new() -> Self

Trait Implementations

impl Default for JsReplTool

fn default() -> Self

Returns the “default value” for a type.

impl Tool for JsReplTool

fn name(&self) -> &str

fn description(&self) -> &str

Human-readable tool description for LLM.

fn classify(&self, _args: &Value) -> ToolClass

Per-call scheduling + permission-gating class (args-aware). Folds the former mutability/call_mutability/concurrency_safe/ call_concurrency_safe hooks into one value. Defaults to the conservative ToolClass::MUTATING_SERIAL (mutating, serial, not promotable).

fn parameters_schema(&self) -> Value

JSON Schema for tool parameters.

fn invoke<'life0, 'async_trait>( &'life0 self, args: Value, ctx: ToolCtx, ) -> Pin<Box<dyn Future<Output = Result<ToolOutcome, ToolError>> + Send + 'async_trait>>

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

The sole execution entry: returns the call’s per-call ToolOutcome (Completed / Running / NeedsHuman), or a ToolError for infrastructure / argument failures (preserved from the former execute).

fn to_schema(&self) -> ToolSchema

Convert tool to LLM-compatible schema.
