Data Transmission
AI commands send regex patterns and test content to api.evolink.ai for analysis by Claude. By setting EVOLINK_API_KEY and using these commands, you consent to this transmission. Data is not stored after the response is returned. The cheatsheet command runs entirely locally and never transmits data.
Network Access

Persistence & Privilege
Temporary files for API payloads are cleaned up automatically. No credentials or persistent data are stored.
