1#!/usr/bin/env node
2// Run one editor-API snippet from a file in the open Harmony editor and print its result.
3//
4//   node scripts/copy/editor-run.mjs <snippet.js> [--site <metaSiteId>] [--max 20000] [--capabilities caps.json]
5//
6// The snippet is the body of an async function with `editorLLMApis` in scope; `return`
7// its result. Keeping snippets in files avoids shell-quoting bugs and leaves a replayable
8// record of every write. Prints the parsed `result` on success, or the editor's failure
9// summary (which lists completed writes: never re-run those, continue from the failed call).
