Why it matters
It gives defenders a runnable way to stop AI agents and malicious dependencies from reading and leaking credentials from disk.
airgap is a Linux-only Rust tool (installable via `cargo install airgap`) that runs AI agents like claude/opencode and package managers like npm inside mount/user namespaces with a FUSE filesystem, redacting secrets in files (.env, SSH/PGP keys, .npmrc) and gating unexpected file access. It is positioned to prevent secret exfiltration by AI agents and malicious npm packages such as the Shai-Hulud worm.
