## Method

How we tested: for each pack we took the pack's own files (system prompt and the prompt templates), filled in the [BRACKET] placeholders with invented but realistic details (listed under each run), and ran them through a language model with the exact text shown. We saved the raw output and wrote down what held and what didn't. These are single runs on one model. Output varies between runs and between models, and your inputs will differ from ours. Treat this as evidence of what the files can do, not as a guarantee.

Model and settings: grok-4.3 (xAI API), temperature 0, one call per run, on 2026-10-23 (America/Louisville time zone).
