Module: Smith::Errors

Defined in:
lib/smith/errors.rb

Overview

Classification surface for host retry policies. Smith owns the answer to "should the workflow attempt be retried?" so consumers don't reimplement the case statement in every Execution / Job.

  @retry_forbidden_classes ||= [
    Smith::ToolCaptureFailed,
    Smith::ToolOutcomeUncertain,

    Smith::ToolFailureNotificationFailed,
    Smith::BoundedCompletionError,
    Smith::PersistedFailureInvalid
  ].freeze
end

.retryable?(error) ⇒ Boolean

Returns true when the host should retry the workflow attempt. AgentError + DeadlineExceeded are always retryable. DeterministicStepFailure + ToolGuardrailFailed honor their retryable attribute (opt-in at the raise site). All other Smith errors and non-Smith errors return false.

Returns:

  • (Boolean)

  end
end

.retryable_classes ⇒ Object

Always-retryable error classes for explicit ActiveJob retry_on allow-lists. Excludes the retryable-bearing families because their retryability is per-raise, not per-class.
