Concurrent Tool Error Propagation

Entry
JSON All of v2.0.58
EntryKind: in v2.0.58,
ChangesSection of the release

What: When one tool in a concurrent execution fails, sibling tools are now gracefully aborted with a clear "Sibling tool call errored" message instead of continuing independently.

Details:

  • New hasErrored flag tracks error state across concurrent tools
  • getAbortReason() distinguishes between user interruption and sibling errors
  • Synthetic error messages clearly indicate why tools were aborted
  • Evidence: Class y30 at line 411600, createSyntheticErrorMessage() at line 411636, getAbortReason() at line 411653 in v2.0.58
