Function classifyErrorCode

pkg/runtime/loop_steps.go:200–214

classifyErrorCode maps a model error to an ErrorCode constant for structured error events. The classification mirrors [modelerrors] but reduces the granularity to a small set of codes that external consumers can act on. Overflow errors are split by [modelerrors.OverflowKind] so the client can rende

(err error)

// can render kind-specific messages (e.g. "request too large" vs "context
// window exceeded") instead of one generic string.
func classifyErrorCode(err error) string {
	switch modelerrors.OverflowKindOf(err) {
	case modelerrors.OverflowKindWire:
		return ErrorCodeRequestTooLarge
	case modelerrors.OverflowKindMedia:
		return ErrorCodeMediaTooLarge
	case modelerrors.OverflowKindTokens:
		return ErrorCodeContextExceeded
	}
	_, rateLimited, _ := modelerrors.ClassifyModelError(err)
	if rateLimited {
		return ErrorCodeRateLimited
	}
	return ErrorCodeModelError
