Tests
This page shows the performance of each test and its scenarios.
Bad Writing Habits

Codex Extraction
Evaluates a model's ability to extract structured codex entries (characters, locations, objects, lore) from prose passages and return them as well-formed XML.

Codex Red Herring (False Positive Detection)
