When to use it
Use it when
Your rough ask sounds like: replay, replay a failure, rerun failed case. 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 examples
Prompt upgrade
Weak ask: Fix this replay flow.
Exact Terms ask: Save agent traces and replay failed scenarios before accepting a fix.
Handoff examples by use case
Architecture prompt
Audit this workflow for Replay and related concerns: Regression set, Observability, Eval harness. Return states, rules, failure modes, and recovery behavior before code.
Implementation prompt
Implement Replay for this app flow. Include data ownership, edge cases, fallback behavior, and acceptance tests.
Test prompt
Create tests that prove Replay 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 Replay with the related vocabulary trail: Regression set, Observability, Eval harness.
