Pigeon, a signed Pass for what a sub-agent may do
TL;DR
Pigeon introduces a signed credential system that limits the actions of sub-agents by providing them with a Pigeon Pass instead of full API access. This enhances security by preventing unauthorized actions in production environments.
✦ Why It Matters
Implement Pigeon to enhance security by limiting sub-agent permissions in your development environment today.
Key Takeaways
- Use Pigeon to issue limited credentials for sub-agents.
- Implement verification to enforce action constraints.
- Avoid sharing full API keys with sub-agents.
- Utilize detailed feedback from Pigeon for denied actions.
How It Works
Pigeon allows a parent agent to create a signed credential, or 'Pigeon Pass', that specifies the capabilities and resources a sub-agent can access. When a sub-agent attempts an action, the parent agent verifies the pass against the requested action and resource, ensuring that only allowed actions are executed.
This mechanism prevents unauthorized access and limits the potential damage from compromised sub-agents.
