What is Pi Purge?
A pi extension for system-prompt experiments: /purge switches which system prompt a session runs with — pi's stock prompt, a trimmed variant, or only a persona prompt. It is meant for prompt engineering work: comparing how the same request behaves when the harness prompt is present, trimmed, or absent; regression-testing your own instructions; and studying instruction-following and prompt-injection robustness under controlled conditions.
