- Renamed AppMessage to AgentMessage throughout - New agent-loop.ts with AgentLoopContext, AgentLoopConfig - Removed transport abstraction, Agent now takes streamFn directly - Extracted streamProxy to proxy.ts utility - Removed agent-loop from pi-ai (now in agent package) - Updated consumers (coding-agent, mom) for AgentMessage rename - Tests updated but some consumers still need migration Known issues: - AgentTool, AgentToolResult not exported from pi-ai - Attachment not exported from pi-agent-core - ProviderTransport removed but still referenced - messageTransformer -> convertToLlm migration incomplete - CustomMessages declaration merging not working properly
