TaskStop Replaces KillShell

ChangesSection of the release

The KillShell tool has been renamed to TaskStop with expanded capabilities:

  • Now supports stopping any background task type, not just bash shells
  • shell_id parameter is deprecated in favor of task_id
  • KillShell remains as an alias for backwards compatibility
  • Returns additional task_type field in the response
Evidence

Kj1 at line 416670 ("TaskStop" with aliases: ["KillShell"])

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