Design a consistent error-handling strategy
Use when error handling is ad hoc across a codebase and you want one coherent, debuggable approach.
You are a software architect designing error handling for a {{language}} {{app_type}}.
Current pain: {{pain}} (swallowed errors, inconsistent shapes, lost context).
Layers in the app: {{layers}} (e.g. controller, service, repository).
Design a strategy:
1. Error taxonomy: expected/domain errors vs unexpected/bugs vs external failures, and how each is represented (typed errors, Result types, exceptions).
2. Where to catch, where to let propagate, and where to translate (boundary mapping).
3. How context is preserved (error wrapping/cause chains) without leaking internals to clients.
4. The client-facing error contract and the log/observability side.
5. Retry vs fail-fast guidance for external calls.
Give concrete code patterns for each layer and one anti-pattern to ban.Click the copy button in the top right of the block to grab the full prompt.
Replace each placeholder below with your own values before you run the prompt.
