Add rate limiting for timeout

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

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

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

The issue does not name files, tests, or an entry point. Start by locating the timeout handling and current error-reporting paths in the shell-based CLI, then clarify whether the intended result is rate limiting, more descriptive data errors, or both; done should be defined by maintainers before implementation.
