Add unit tests for parsers

**Description**
Currently hooks lacks proper monitoring support.

**Proposed solution**
Add configurable monitoring with sensible defaults.

**Priority**: Low/Medium

Start by locating the parser and hooks implementations, then compare the issue title with the proposed monitoring work to determine the intended scope. Identify the existing test entry points and clarify whether “done” means parser coverage or configurable hook monitoring with defaults before making changes.
