What

When Claude Code cannot create a temporary folder because the disk is full, the error now carries an extra error code.

Several small pieces were also added:

  • Team records gained a field naming a lead process.
  • A configuration option called declare_task was added, off by default.
  • A hold option lets a later worker hold the first turn. A worker is a separate process that does part of the job.
  • A usage measurement now leaves out tool descriptions that were never sent.
  • Tasks that save memory after a turn are left out of a task listing.
Why

Most of these are parts of features still being built. Who uses them, and their defaults beyond the one noted, are not yet clear.
