Support logging configuration

**Problem**
When working with lib, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

No files, tests, or entry points are named. Start by locating the agent's logging configuration and error-handling entry points, then determine the desired configuration surface and current error paths. Done means logging can be configured and error messages provide the requested additional detail, with relevant tests or command checks passing.
