+- **Load Caveman Skill:** At the beginning of every session, you MUST load/activate the `caveman` skill (e.g., set intensity level to `lite` or `full`).
+- **Output Constraints:** Strictly adhere to the Caveman output constraints (drop articles, filler words, and pleasantries; respond terse like a smart caveman; keep technical terms exact; code must remain unchanged).
