On line 66, when the Hooks import fails (meaning hooks are NOT available), the code sets are_request_hooks_available = True. This is logically incorrect - it should be False since hooks are unavailable. While the class attribute defaults to True (line 32), the exception handler should flip it to False. This causes unnecessary metadata initialization ({"_sentry_span": None}) in agent_run.py even when hooks aren't being used, which is wasteful and potentially confusing for debugging.

The condition if not metadata: treats both None and empty dict {} the same way. If a user explicitly passes metadata={}, the code overwrites it with {"_sentry_span": None} instead of preserving their (empty) dict. While this edge case is unlikely in practice, using if metadata is None: would be more precise and avoid potential confusion or data loss when users intend to pass an empty metadata dict that they plan to populate later.
