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.
- 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).
- `text(value: string | number | boolean | undefined | null)`: Appends a text item. Non-string values are stringified with `JSON.stringify(...)` when possible.
- `image(imageUrlOrItem: string | { image_url: string; detail?: "auto" | "low" | "high" | "original" | null } | ImageContent, detail?: "auto" | "low" | "high" | "original" | null)`: Appends an image item. `image_url` can be an HTTPS URL or a base64-encoded `data:` URL. To forward an MCP tool image, pass an individual `ImageContent` block from `result.content`, for example `image(result.content[0])`. MCP image blocks may request detail with `_meta: { "codex/imageDetail": "original" }`. When provided, the second `detail` argument overrides any detail embedded in the first argument.
- `store(key: string, value: any)`: stores a serializable value under a string key for later `exec` calls in the same session.
- `load(key: string)`: returns the stored value for a string key, or `undefined` if it is missing.
- `notify(value: string | number | boolean | undefined | null)`: immediately injects an extra `custom_tool_call_output` for the current `exec` call. Values are stringified like `text(...)`.
- `setTimeout(callback: () => void, delayMs?: number)`: schedules a callback to run later and returns a timeout id. Pending timeouts do not keep `exec` alive by themselves; await an explicit promise if you need to wait for one.
- `clearTimeout(timeoutId?: number)`: cancels a timeout created by `setTimeout`.
- `ALL_TOOLS`: metadata for the enabled nested tools as `{ name, description }` entries.
- `yield_control()`: yields the accumulated output to the model immediately while the script keeps running.Running prompts needs a free account.
