Pull Request Overview
This PR introduces performance optimizations by wrapping error checks in debug conditions so that certain exceptions are only raised in non-optimized (debug) mode. The key changes include:
- Using debug blocks to conditionally raise exceptions in production builds.
- Changing some exception types for missing initialization or attribute errors.
- Applying the debug wraps across multiple modules, including model, abstract agents, and example agent implementations.
Reviewed Changes

| File | Description |
|---|---|
| mesa_frames/concrete/model.py | Wrapped error checks in debug and changed the exception type on missing init |
| mesa_frames/concrete/agents.py | Applied debug flag in getattr, potentially bypassing error checks |
| mesa_frames/abstract/agents.py | Modified exception type in getattr when _agents is missing |
| examples/sugarscape_ig/ss_polars/agents.py | Added debug conditions around NotImplementedError for unimplemented methods |

178-181: Good optimization for runtime error handling.The change conditionally checks for missing attribute initialization only in debug mode, which aligns with the PR objective of performance optimization.
Consider using a more explicit error cascade by using
raise ... from None:if __debug__: # Only execute in non-optimized mode - raise RuntimeError( + raise RuntimeError( "You haven't called super().__init__() in your model. Make sure to call it in your __init__ method." - ) + ) from None🧰 Tools

185-188: Type validation optimization aligned with PR goals.Making type checking conditional on debug mode is consistent with the optimization objective.
For better readability, you could simplify the nested if statements:
-if __debug__: # Only execute in non-optimized mode - if not isinstance(agents, AgentsDF): - raise TypeError("agents must be an instance of AgentsDF") +if __debug__ and not isinstance(agents, AgentsDF): # Only execute in non-optimized mode + raise TypeError("agents must be an instance of AgentsDF")🧰 Tools

442-446: Good optimization for attribute error handling.The change conditionally raises AttributeError for private attributes only in debug mode, which aligns with the PR objective.
To improve readability, consider simplifying the nested if statements:

1001-1005: Good improvement for error handling optimization and type.Converting from RuntimeError to AttributeError for missing attributes is more semantically appropriate, and making it conditional in debug mode aligns with the optimization goal.
To improve readability, consider simplifying the nested if statements:

You probably forgot to call super().__init__ in the __init__ method." - ) +if __debug__ and name == "_agents": # Only execute in non-optimized mode + raise AttributeError( + "The _agents attribute is not set.

170-314: Document the effects of running with -O flag.The optimization strategy is well-implemented, but could benefit from documentation explaining the behavior differences when running with the -O flag.
Consider adding a class-level docstring that explains the optimization strategy:
class AntPolarsBase(AgentSetPolars): """Base class for ant agents using Polars dataframes. Note: When running Python with the -O flag, certain runtime checks (like NotImplementedError for abstract methods) are disabled for performance optimization. Ensure all subclasses properly implement required methods to avoid unexpected behavior in production. """🧰 Tools
