Hide Secrets from AI Agents and NPM install using Airgap

Airgap is a Linux security tool that protects sensitive credentials from AI agents and malicious npm packages by running programs in isolated namespaces and redacting secrets from files like .env and .npmrc. The tool prevents threats like the Shai-Hulud worm, which steals credentials during npm installations, by hiding real secret values while allowing programs to still access and work with files. Users can install airgap via Rust's cargo package manager, and it currently supports AI agents like Claude and opencode with redaction-only access, plus npm with interactive file permission gates.
