Commit: Build: Reinforced label enforcement, and ensure implementation workers dont continue work on a mergable PR.
Branch: main
SHA: 5a9aaa79ed

Background and Context

retry_auto_debug in src/cleveragents/core/retry_service_patterns.py tracks the last error in a variable typed as Exception | str | None. When the decorated function returns a dict with an "error" key (rather than raising an exception), last_error is set to str(error_value) — a plain string. At the end of the retry loop, if all attempts fail via this dict-error path, the code raises Exception(last_error) — a generic Exception wrapping a string.

This loses all error type information: callers cannot distinguish between a NetworkError, ProviderError, or any other domain-specific error type. The error handling hierarchy defined in exceptions.py is bypassed entirely.

Current Behavior

# In retry_service_patterns.py - retry_auto_debug wrapper:
last_error: Exception | str | None = None

# When result is a dict with "error" key:
error_value: Any = result.get("error")
if error_value is not None:
    last_error = str(error_value)   # ← string, loses type info
    ...

# At end of all attempts:
if last_error is not None:
    if isinstance(last_error, Exception):
        raise last_error   # ← correct for exception path
    raise Exception(last_error)   # ← generic Exception for string path, loses type!

Expected Behavior

When the dict-error path is taken, the error should be wrapped in a domain-appropriate exception type rather than a generic Exception. At minimum, it should use CleverAgentsError or ExecutionError from the exception hierarchy:

from cleveragents.core.exceptions import ExecutionError

# At end of all attempts:
if last_error is not None:
    if isinstance(last_error, Exception):
        raise last_error
    raise ExecutionError(str(last_error))   # ← domain-specific exception

This preserves the error handling hierarchy and allows callers to catch specific exception types.

Acceptance Criteria

When retry_auto_debug exhausts all attempts via the dict-error path, it raises a CleverAgentsError subclass (not a generic Exception)
The error message is preserved
Callers can catch the raised exception using the domain exception hierarchy
BDD test scenario verifies the exception type on the dict-error exhaustion path

Subtasks

Replace raise Exception(last_error) with raise ExecutionError(str(last_error)) (or appropriate subclass)
Import the appropriate exception type in retry_service_patterns.py
Add BDD test verifying exception type on dict-error exhaustion
Verify no existing tests break

Definition of Done

The issue is closed when retry_auto_debug raises a domain-specific exception (not generic Exception) when exhausting retries via the dict-error path, with a passing BDD test, merged to main.

When the decorated function returns a dict with an `"error"` key (rather than raising an exception), `last_error` is set to `str(error_value)` — a plain string. At the end of the retry loop, if all attempts fail via this dict-error path, the code raises `Exception(last_error)` — a generic `Exception` wrapping a string. This loses all error type information: callers cannot distinguish between a `NetworkError`, `ProviderError`, or any other domain-specific error type. The error handling hierarchy defined in `exceptions.py` is bypassed entirely. ## Current Behavior ```python # In retry_service_patterns.py - retry_auto_debug wrapper: last_error: Exception | str | None = None # When result is a dict with "error" key: error_value: Any = result.get("error") if error_value is not None: last_error = str(error_value) # ← string, loses type info ... # At end of all attempts: if last_error is not None: if isinstance(last_error, Exception): raise last_error # ← correct for exception path raise Exception(last_error) # ← generic Exception for string path, loses type! ``` ## Expected Behavior When the dict-error path is taken, the error should be wrapped in a domain-appropriate exception type rather than a generic `Exception`.

✅ Verified — Bug: error type information lost when retry_auto_debug raises generic Exception. MoSCoW: Should-have. Priority: Medium — error type preservation is important for debugging.
