Prompt templates by use case
Architecture prompt
Audit this workflow for Optimistic UI and related concerns: Pending state, Rollback, Error recovery. Return states, rules, failure modes, and recovery behavior before code.
Implementation prompt
Implement Optimistic UI for this app flow. Include data ownership, edge cases, fallback behavior, and acceptance tests.
Test prompt
Create tests that prove Optimistic UI works across refresh, retry, back/next movement, partial failure, and return visits.
