Idempotency, Retry policy, Deduplication, Exactly once
When to use it
Use it when
Your rough ask sounds like: retry, duplicate, same action twice. The term gives your coding agent a clearer problem shape.
When not to use it
Do not use this term as a request for a quick screen fix. Use it when the system needs explicit state, rules, failures, or recovery behavior.
Copy-ready handoff phrase
Before and after
Weak ask
Fix this retry flow.
Exact Terms ask
Add idempotency keys so retries and double submits cannot create duplicate side effects.
Prompt templates by use case
Architecture prompt
Audit this workflow for Idempotency and related concerns: Retry policy, Deduplication, Exactly once. Return states, rules, failure modes, and recovery behavior before code.
Implementation prompt
Implement Idempotency for this app flow. Include data ownership, edge cases, fallback behavior, and acceptance tests.
Test prompt
Create tests that prove Idempotency works across refresh, retry, back/next movement, partial failure, and return visits.
Common mistake
What goes wrong
Asking for code before defining states, transitions, persistence, and failure behavior.
Better move
Use Idempotency with the related vocabulary trail: Retry policy, Deduplication, Exactly once.
