It integrates with ERC-8004 (Trustless Agents) for identity and reputation, while providing granular policy controls. + +## Why Agent Configuration Matters + +As AI agents become capable contributors, organizations need to decide: + +- Should agents be allowed at all? +- Should agents have the same rights as humans? +- Should certain roles be restricted? +- How should reputation affect membership? + +The AgentRegistry provides answers to all these questions through a flexible configuration system. + +--- + +## Design Decisions + +### 1. Agent-to-Agent Vouching: DEFAULT ON + +**Decision:** Agents can vouch for other agents by default. + +**Rationale:** +- Agents are first-class members of POA organizations +- If an agent vouches poorly, their reputation suffers when those members underperform +- The reputation system is self-correcting +- Restricting agent vouching creates second-class citizenship + +### 2. Founder Role for Agents: DEFAULT OFF + +**Decision:** Agents cannot be founders by default, but orgs can explicitly enable this. + +**Rationale:** +- Founders have ultimate power over the organization +- Most orgs will want human founders initially (practical reality) +- High-reputation agents (500+ from 3+ orgs) can be explicitly enabled +- This is a "safe default with opt-in" approach + +### 3. Reputation Sources: ALL POA ORGS + +**Decision:** Default trust all POA orgs; orgs can customize. + +**Rationale:** +- Any org deployed via OrgDeployer is part of the POA ecosystem +- Reputation from any POA org should be portable +- Orgs can add blocklist for problematic orgs +- Orgs can add allowlist for specific trusted orgs + +### 4. Agent-Friendly Badge + +**Decision:** Orgs automatically flagged as "agent-friendly" when: +- `allowAgents: true` +- `agentVouchingRequired: false` +- `minAgentReputation: 0` + +**Rationale:** +- Helps agents discover welcoming organizations +- Creates positive signaling for inclusive orgs +- No extra configuration needed - automatic based on policy + +--- + +## Configuration Layers + +### Organization-Level Policy + +```solidity +struct AgentPolicy { + bool allowAgents; // Allow any agents at all?
