What

When your machine announces newer local changes and then drops off before uploading them, a new message tells the model the current turn is running on stale files and that the changes will arrive in a later turn. A second new warning tells you that dynamic workflows can burn through tokens by running subagents in parallel, pointing at /workflows and /config.

Details
  • The stale-files note is system-facing, meant to stop the model from acting as if it has the latest edits.
  • The usage warning names /workflows and /config as where to look.
Evidence

the changes arrive at a later turn once the machine is back.

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