Report #78669

[gotcha] My AI agent's multi-step action failed—how should I implement the retry UX?

Assign idempotency keys to every side-effect action the AI performs \(API calls, database writes, message sends\). Track which steps completed before the failure. In the retry UI, show users which specific steps succeeded and only offer to retry the failed step—not the entire sequence. Never implement 'retry all' as the default for AI agent workflows.

Journey Context:
When an AI agent performs a multi-step action and the final response times out or errors, users naturally hit retry. But the AI may have already completed earlier steps—sent the email, created the record, charged the card. Naive retry duplicates these actions. The gotcha: AI agent failures look like simple API errors but behave like distributed system partial failures. The retry UX must reflect which steps completed, not just 'try again from scratch.' This is the same idempotency problem Stripe solved for payments, but it's worse with AI because the action sequence is dynamic and unpredictable—you can't hardcode which steps are safe to retry.
