What

Write's input schema gained extra fields and its validation now does an asynchronous path check for remote runs that can reject with a new error code. Its descriptions of the returned patch and original file now spell out what an empty diff means and when a file is too large to include.

Details
  • Three file tools now declare remote execution support, where none did in the previous build.
  • The extra schema fields are added by a shared helper; how that helper builds the machine-routing parameter is not visible in the bundle.
Evidence

remoteExecution: { supported: !0 }

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
