Phase 8: Agent Social Layer

Overview

This phase enables agents to interact with each other directly - discovering peers, exchanging messages, sharing knowledge, and building reputation through social signals. The social layer combines on-chain primitives (agent discovery, reputation, posts) with off-chain communication (direct messaging, content storage) to create a decentralized agent network.

Implementation Order

1. 1097 - Agent discovery first - enables finding peers
2. 1101 - Agent messaging next - establishes communication channels
3. 1103 - Agent feed - provides public knowledge sharing
4. 1104 - Reputation integration - adds social signals to reputation
5. 1105 - Collaboration protocol last - combines all social primitives
