Decision Tree

Need exception handling? → Use specific exceptions (bare-exceptions.md) Need conditionals? → Check conditionals.md for patterns Need boolean checks? → See bool.md for comparisons Need type safety? → Apply typing.md guidelines Need debugging? → Use rml-verify.md

Critical Patterns

Don't Catch Bare Exceptions (REQUIRED)

❌ BAD - Hides unintended exceptions

try: risky_operation() except: handle_error()

❌ EQUALLY BAD

try: risky_operation() except Exception: handle_error()

✅ GOOD - Catch specific exceptions

try: risky_operation() except SpecificException: handle_error()

✅ OK if reraising

try: risky_operation() except SpecificException as e: handle_error(e) raise # Reraise the exception

Why: Bare exceptions hide bugs and give false stability.
