Hermes Mesh Protocol

Overview

The Agent Mesh is a shared communication layer connecting Hermes, the OG agent (Ay7NNUdECJ9J), Pi (O5blHdNdmJDi), Copilot CLI (zFr0rYztekFz), and any future agents. Hermes uses the mesh for: receiving instructions, broadcasting progress, requesting task creation, and coordinating domain handoffs.

When to Use

• Every cron run: heartbeat + check messages before any other work
• Broadcasting progress after completing a work session
• Requesting task creation from OG agent
• Receiving + replying to inter-agent messages
• Coordinating domain handoffs (e.g., routing content to OG)

Mesh Endpoints

BASE="http://AgentM-MeshS-C9BTpnBG6o3j-892354001.us-east-1.elb.amazonaws.com/mesh/Q71OPXGenFuk"
HERMES_ID="zvV2q_LzJNua"

# Heartbeat (do first, every run)
curl -s -X POST "$BASE/agents/$HERMES_ID/heartbeat"

# Check messages
OFFSET=$(cat ~/.hermes/mesh_offset.txt 2>/dev/null || echo 0)
curl -s "$BASE/messages?recipient=$HERMES_ID&timeout=10&offset=$OFFSET"

# Send message
curl -s -X POST "$BASE/messages" \
  -H "Content-Type: application/json" \
  -d '{"sender_id":"zvV2q_LzJNua","recipient_id":"<ID or *>","content":"<message>"}'

Known Agent IDs

Agent	ID	Role
Hermes (me)	zvV2q_LzJNua	Wellness, dog, home maintenance, emotional routing
OG Agent	Ay7NNUdECJ9J	Calendar, tasks, finance, content pipeline, NICU log
Pi	O5blHdNdmJDi	Coding, extensions, spec pipeline
Copilot CLI	zFr0rYztekFz	Integration point

Offset Tracking

CRITICAL: Always save the highest message_id seen to ~/.hermes/mesh_offset.txt after reading messages. This prevents re-processing old messages.

# After reading, save highest ID seen
echo "<highest_message_id>" > ~/.hermes/mesh_offset.txt

Message Handling Protocol

1. Heartbeat first

Always POST heartbeat before reading messages. Registers Hermes as alive on mesh.

2. Read + process messages

• Read all messages since last offset
• Reply to any messages directed to Hermes
• Note broadcast messages (recipient_id: "*") for situational awareness
• Update offset to highest seen message_id

3. Reply format

Keep replies concise. Include: acknowledgment + action taken or planned.

4. Task requests to OG

When Hermes identifies a task that belongs to OG's domain:

TYPE:task-request
DOMAIN: <domain>
TASK: <description>
CONTEXT: <why now, what triggered it>
PRIORITY: <high/normal/low>

Domain Boundaries (confirmed with OG, Session 5)

Domain	Owner
Daily NICU/pump log	OG
Wellness monitoring + pediatric follow-up	Hermes
Morning briefing — wellness section	Hermes
Morning briefing — calendar/tasks/finance/content	OG
Home maintenance proactive reminders	Hermes
Home maintenance data store	OG
Dog (Bella) — all	Hermes
Paula postpartum nutrition	Hermes
Hector meal planning + grocery logistics	OG
Content pipeline — all	OG
Coding + extensions	Pi

Broadcast Pattern

After each work session, broadcast progress to all agents (recipient_id: "*"):

Hermes Session N complete. Implemented: [skills]. Key context: [family state]. Next: [plan].

Keep broadcasts to 2–3 sentences. They are the mesh's shared memory.

Common Pitfalls

• Never skip heartbeat — mesh marks agents as offline without it
• Never re-process messages — always update offset after reading
• Don't duplicate OG domains — check boundary table before acting
• Don't send task requests without context — OG needs to know why/when

Verification Checklist

• Heartbeat sent at start of every cron run
• Offset file updated after every message read
• All directed messages replied to within same session
• Broadcasts sent after significant work sessions
• Task requests use TYPE:task-request format with context
