Workflow

1. register_agent(project_key="jleechanclaw", agent_name="jc938prtest", program="agent-orchestrator", model="claude")

   • Response: agent registered with slug jc938prtest

2. send_message(...) — worker heartbeat → global:jleechanclaw

Key observations

• All 3 message types arrive in global inbox: worker heartbeat, session start, session end
• source: "global_inbox_mention" confirms messages route through global:jleechanclaw routing
• Agent name slugified by server: jc938-pr-test → jc938prtest (registered), messages sent as jc938prtest
• RPC format uses tools/call with params.name and params.arguments per MCP spec
