Peer Messaging Skill
Purpose
Enables cross-session coordination between multiple Claude Code instances through the claude-peers-mcp broker. Complements Agent Teams (R018, intra-session) with inter-session messaging.
Scope Clarification
| Scope | Mechanism | Tools | Use Case | |-------|-----------|-------|----------| | Intra-session agents | Agent Teams (R018) | TeamCreate, SendMessage | Single session multi-agent collaboration | | Cross-session instances | claude-peers-mcp | list_peers, send_message | Multi-terminal/project real-time coordination | | Cross-session memory | claude-mem | save_memory, search | Async memory persistence |
Important: R018's
SendMessageand claude-peers-mcp'ssend_messageare different tools with different scopes. Do not confuse them.
MCP Tool Mapping
| Tool | Purpose | oh-my-customcode Scenario |
|------|---------|---------------------------|
| list_peers | Discover active Claude instances | omcustom:status system overview |
| send_message | Send message to peer | Cross-project workflow coordination |
| set_summary | Broadcast current task summary | DAG cross-project step sync |
| check_messages | Read incoming messages | Receive coordination signals |
Use Cases
Multi-Project Workflow
Terminal A runs auto-dev on project-1; Terminal B works on dependent project-2. Peers coordinate via messages when blocking dependencies are resolved.
Cross-Project QA
Share test infrastructure state between projects running concurrent test suites.
DAG Bridge
dag-orchestration cross-project steps can use peer messaging for synchronization (currently impossible without this tool).
Setup
# Install broker (optional MCP server)
npm install -g claude-peers-mcp
# Add to MCP config
claude mcp add claude-peers-mcp -- npx claude-peers-mcp
Integration
- Works with R018 Agent Teams (different scope, complementary)
- Works with claude-mem (async vs sync messaging)
- Works with
omcustom:status(peer discovery) - Broker runs on localhost:7899 (SQLite-backed)
