The bundled JSHint fork in ace-builds 1.24.2 (still present
unchanged in 1.43.6) never plumbs state.option.module into the
prefix("await", ...) handler, so a /* jshint module: true */
directive is silently ignored for top-level await expressions in
the MCP custom tool function body editor. The handler falls into
its "treat await as identifier" branch and produces a misleading
"Missing ';' before statement." error on otherwise valid code.
Patch the minified worker so the handler takes a module-mode
path that parses the await operand as an expression without
requiring a surrounding async function. Async-function behavior
is unchanged.
Customers can now write:
/* jshint esversion: 11, module: true */
const res = await fetch(...);
in the custom tool function body editor and get clean linting.
Runtime was already fine — the daemon wraps the body in an
async IIFE at custom-tools.service.ts, so this was purely a
cosmetic editor warning, but a disruptive one.
A marker comment is prepended to worker-javascript.js so future
ace-builds upgrades know to re-audit this patch.
