Improve error messages in parsers

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

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

**Priority**: Low/Medium

First resolve the mismatch between the title’s parser error-message request and the description’s hooks caching request. Locate the parser and hook entry points, inspect their current behavior and tests if present, then confirm whether done means clearer parser errors or configurable caching with sensible defaults.
