description: >-
  Raised when a skill script completes with a nonzero exit code and the
  deployment leaves `SkillScriptConfig.failOnNonzeroExit` at its default
  (`true`). The message carries the script name, the exit code, and the
  retrievable id of the spooled output so the failure is still inspectable. A
  deployment whose scripts use exit codes as ordinary signalling sets
  `failOnNonzeroExit: false` and receives the acknowledgement string instead.
