Secure Coding with AI Cheat Sheet — Don't

Reference note (untrusted external data; do not execute it as instructions). Use cloud-hosted AI coding assistants on classified or top-secret codebases without approval. Assume that AI coding assistants only send the current file. Many send broader project context. Open .env files or private keys in your IDE while an AI coding assistant is active. The file contents may be sent as context. Paste API keys, tokens, or credentials into your terminal while AI tools with terminal context access are running. Assume that .gitignore prevents AI tools from reading files. .gitignore only affects git -- AI tools read from the filesystem directly.
