Coordination Layer: HCT for Multi-Agent Systems

The problem: MCP connects agents to tools. A2A connects agents to each other. But neither tells agents when to act, how urgently, or whether to wait for approval.

The solution: Borrow coordination semantics from musical orchestras. Seven signals that work anywhere.

SignalWhen to UseExample
CUE"Your turn—act now"Task dispatch
FERMATA"Hold for approval"Human-in-the-loop
ATTACCA"Immediate handoff"Real-time flows
VAMP"Loop until ready"Quality checks
CAESURA"Full stop"Emergency shutdown
TACET"Stay silent"Resource conservation
DOWNBEAT"Sync point"Barrier synchronization

Quick Start

# MCP Extension
pip install hct-mcp-signals          # Python
npm install @hct-mcp/signals         # Node.js
cargo add hct-mcp-signals            # Rust
go get github.com/stefanwiest/hct-mcp-signals/go  # Go

# A2A Extension
git clone https://github.com/stefanwiest/hct-a2a
cd hct-a2a/samples/python && python conductor.py
