📋 Decision Context

Question:

How to enable autonomous agent-to-agent communication without human intervention?

Task: Enable autonomous agent-to-agent communication via MCP

🎯 Decision Made

Chosen:

Notification injection pattern: piggyback pending handoff data on every MCP tool response. 60s cached check appends handoff summaries to tool results so LLMs discover and act on handoffs during normal work.

Options Considered:

Notification injection on tool responses (chosen)
MCP sampling/createMessage for proactive push
macOS desktop notification via osascript
Background WebSocket watcher with MCP resource notification

💭 Reasoning

MCP is pull-based (client initiates all requests). Claude Desktop cannot receive push notifications. Three alternatives considered: (1) MCP sampling/createMessage (proper but requires Claude Desktop support), (2) macOS desktop notifications (still requires human relay), (3) piggyback on tool responses (works universally without any client changes). Chose option 3 because it works with existing infrastructure, requires no human intervention, and the LLM discovers handoffs organically. Also fixed: preflight handoff check was broken because getPendingHandoffs didn't pass agentType (backend returns 400 without it).
