Pigeon, a signed Pass for what a sub-agent may do
Pigeon is a new security tool designed to limit the permissions of sub-agents spawned by AI agents. By using signed 'Pigeon Passes,' developers can ensure sub-agents only have access to the specific resources they need, preventing unauthorized actions.
Why it matters
As AI agents become more autonomous, securing their interactions and preventing privilege escalation is a critical challenge for software security.
Your agent spawned a sub-agent and handed it the same API key. That sub-agent can now deploy to production, read the payments database, and merge to main.
Pigeon stops that. You hand the child a Pigeon Pass : a narrowed, signed credential for what it may do, not a copy of everything you can do.
