A codebase scan has revealed widespread use of broad except: and except Exception: blocks. This practice violates the project's error handling guidelines, which mandate that exceptions should be allowed to propagate unless they can be handled meaningfully.

Catching broad exceptions can mask underlying issues, complicate debugging, and lead to unexpected behavior. To improve the robustness and maintainability of the code, these broad exception handlers should be replaced with more specific exception types.

Recommendation:

Review all occurrences of except: and except Exception: and replace them with specific exception types that can be handled appropriately in the local context. If the exception cannot be handled locally, it should be allowed to propagate to a higher-level handler.

To find all occurrences, run the following commands:

grep -r 'except:' src/cleveragents
grep -r 'except Exception:' src/cleveragents

State: Verified ✅
Priority: Backlog (unchanged)
Milestone: v3.7.0 (assigned)
MoSCoW: Could Have — Replacing broad exception handling with specific types is good practice per CONTRIBUTING.md error handling guidelines, but this is a refactoring task that doesn't change behavior. It can be deferred if higher-priority work demands attention.

State: Verified
Priority: Backlog — error handling improvement with no behavior change
Milestone: v3.8.0
MoSCoW: Could Have — replacing broad exception handling is desirable per CONTRIBUTING.md guidelines but is a large-scale refactoring effort. The existing code functions correctly. This should be done incrementally.
