## FAQ

### What is AgentShield?

AgentShield is an open-source, zero-leak runtime security layer and OS kernel sandbox designed to prevent autonomous AI coding agents from exfiltrating credentials or reading unauthorized files.

### How does AgentShield differ from running agents in Docker?

Unlike heavy container virtualization, AgentShield uses sub-millisecond unprivileged native kernel isolation like Bubblewrap on Linux or Apple Seatbelt on macOS to intercept and replace real credentials with synthetic tokens.

### How does AgentShield neutralize prompt injection exfiltration?

It uses a synthetic canary decoy to return fake honeytokens when files are read and a CIDR egress firewall to reject unauthorized outbound network sockets at the kernel level.

### Can I use AgentShield with Claude Code?

Yes, you can use a one-command generator to configure Claude Code to intercept terminal executions via a PreToolUse hook.
