- Runs raw JavaScript in an isolated context (no Node, no file system, or network access, no console).
- Send raw JavaScript source text, not JSON, quoted strings, or markdown code fences.
const EXEC_DESCRIPTION_TEMPLATE: &str = r#"Run JavaScript code to orchestrate/compose tool calls
- Evaluates the provided JavaScript code in a fresh V8 isolate as an async module.
- All nested tools are available on the global `tools` object, for example `await tools.exec_command(...)`. Tool names are exposed as normalized JavaScript identifiers, for example `await tools.mcp__ologs__get_profile(...)`.
- Nested tool methods take either a string or an object as their input argument.
- Nested tools return either an object or a string, based on the description.
- Runs raw JavaScript -- no Node, no file system, no network access, no console.
- Accepts raw JavaScript source text, not JSON, quoted strings, or markdown code fences.
- You may optionally start the tool input with a first-line pragma like `// @exec: {"yield_time_ms": 10000, "max_output_tokens": 1000}`.
- `yield_time_ms` asks `exec` to yield early after that many milliseconds if the script is still running.
- `max_output_tokens` sets the token budget for direct `exec` results. By default the result is truncated to 10000 tokens.
- All nested tools are available on the global `tools` object, for example `await tools.exec_command(...)`. Tool names are exposed as normalized JavaScript identifiers, for example `await tools.mcp__ologs__get_profile(...)`.
- Tool methods take either string or object as parameter.
- They return either a structured value or a string based on the description above.
- When the JS code is fully evaluated, the isolate's lifetime ends and unawaited promises are silently discarded.
- Global helpers:
- `exit()`: Immediately ends the current script successfully (like an early return from the top level).
