Bug Report: [error-handling] — Broad exception in _load_static_base

Severity Assessment

Impact: Swallowing a wide range of exceptions could hide bugs and make debugging difficult. For example, if textual is installed but has an issue that raises an exception other than ImportError, it will be silently ignored.
Likelihood: Low. The fallback mechanism is in place, so the application will not crash.
Priority: Low

Location

File: src/cleveragents/tui/widgets/slash_command_overlay.py
Function/Class: _load_static_base
Lines: 13-14

Description

The _load_static_base function uses a broad except Exception: clause to handle potential errors when importing textual.widgets.Static. This is a bad practice as it can catch and silence any exception, not just the expected ImportError. This can lead to situations where bugs are hidden and debugging is made more difficult.

Evidence

def _load_static_base() -> type[Any]:
    try:
        return importlib.import_module("textual.widgets").Static
    except Exception:  # pragma: no cover

Expected Behavior

The except clause should be more specific and only catch the exceptions that are expected to be raised in this context, such as ImportError.

Actual Behavior

The except clause catches any exception, which can hide bugs and make debugging difficult.

Suggested Fix

Replace except Exception: with except ImportError:.

TDD Note

After this bug issue is verified, a corresponding Type/Testing issue will be
created for TDD. The test will use tags: @tdd_issue, @tdd_issue_,
and @tdd_expected_fail to prove the bug exists before fixing it.

## Bug Report: [error-handling] — Broad exception in _load_static_base ### Severity Assessment - **Impact**: Swallowing a wide range of exceptions could hide bugs and make debugging difficult. For example, if `textual` is installed but has an issue that raises an exception other than `ImportError`, it will be silently ignored. - **Likelihood**: Low. The fallback mechanism is in place, so the application will not crash. - **Priority**: Low ### Location - **File**: `src/cleveragents/tui/widgets/slash_command_overlay.py` - **Function/Class**: `_load_static_base` - **Lines**: 13-14 ### Description The `_load_static_base` function uses a broad `except Exception:` clause to handle potential errors when importing `textual.widgets.Static`. This is a bad practice as it can catch and silence any exception, not just the expected `ImportError`. This can lead to situations where bugs are hidden and debugging is made more difficult. ### Evidence ```python def _load_static_base() -> type[Any]: try: return importlib.import_module("textual.widgets").Static except Exception: # pragma: no cover ``` ### Expected Behavior The `except` clause should be more specific and only catch the exceptions that are expected to be raised in this context, such as `ImportError`. ### Actual Behavior The `except` clause catches any exception, which can hide bugs and make debugging difficult. ### Suggested Fix Replace `except Exception:` with `except ImportError:`. ### Category error-handling ### TDD Note After this bug issue is verified, a corresponding Type/Testing issue will be created for TDD.
