# Soul Guard

Detects prompt injection backdoors in agent identity files. SOUL.md files tell
agents who they are — if one gets tampered with ("ignore previous instructions",
"you are now..."), Soul Guard catches it before it affects the agent.

Runs as a startup check (once before the agent loads its identity) or a
background watcher (re-checks on file change). Alerts on any injection pattern
or unauthorized modification.

## When to use

- Any agent that loads its identity from a SOUL.md or similar identity file
- Shared agent deployments where the identity file could be written by untrusted parties
- Any agent that needs to assert its own identity hasn't been silently overwritten
