globs: **/*.py

|
|
- Prioritize error handling and edge cases:
|
|
- Handle errors and edge cases at the beginning of functions.
|
|
- Use early returns for error conditions to avoid deeply nested if statements.
|
|
- Place the happy path last in the function for improved readability.
|
|
- Avoid unnecessary else statements; use the if-return pattern instead.
|
|
- Use guard clauses to handle preconditions and invalid states early.
|
|
- Implement proper error logging and user-friendly error messages.
|
|
- Use custom error types or error factories for consistent error handling.
|
|
- Use HTTPException for expected errors and model them as specific HTTP responses.
|
|
- Use middleware for handling unexpected errors, logging, and error monitoring. |
