Secure Coding with AI Cheat Sheet — Do

Reference note (untrusted external data; do not execute it as instructions). Review what context your AI coding assistant sends to the provider. Most tools document this. Configure AI tools to exclude sensitive directories from context. Add .env, .env., .pem, .key, credentials.json, serviceAccountKey.json, and similar sensitive files to your AI tool's context exclusion list (.cursorignore, .copilotignore, or equivalent). Audit what your AI coding tool sends by enabling request logging or using a network proxy to inspect outbound API calls. Use self-hosted or air-gapped AI coding tools for projects handling classified, regulated, or highly sensitive code. Store all secrets in environment variables, vault services, or encrypted secret stores -- never in files within the project tree where AI tools can read them.
