Phobos

Validates Syringe hooks (DEFINE_HOOK / DEFINE_HOOK_AGAIN) on the current branch during code review. Trigger whenever new or modified hooks need validation.

A "tag" is an INI key that generally corresponds to a C++ property. Defining a tag requires modifications in four places within the target `ExtData` class: **declaration**, **initialization**, **serialization**, and **INI loading**. If the user does not provide all information explicitly, the AI should infer the missing pieces, present them to the user for confirmation, and only proceed after approval.

### Write Documentation This command is invoked when the code changes for a feature or bugfix are complete on a branch (branched from `develop`) and documentation is the only remaining task. The AI should discover what changed, categorize it, and write the appropriate documentation entries.
