**Problem**
When working with parsers, 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 any files, tests, or parser entry points. Start by locating the parser error-handling paths in the repository and review how current errors are reported; clarify the expected detailed messages before changing anything. Done means parser failures provide consistently more descriptive errors and the relevant behavior is covered by tests.
