Score	Level	Auto-Approve
0.9+	High	Yes
0.7+	Good	No
0.5+	Neutral	No
0.3+	Low	No
<0.3	Critical	No

1. create_agent_identity — Register the agent
2. authorize_action — Request permission for an action
3. verify_authorization — Verify the token before executing
4. Trust score updates automatically based on activity

Data Storage

All identity data is stored locally in SQLite at ~/.agent-identity/identities.db.
