Hermes Agent Optimization

Skill by ara.so — Hermes Skills collection.

Hermes Agent is an autonomous AI agent framework that orchestrates LLM calls across 20+ platforms (Telegram, Discord, Slack, CLI, webhooks), integrates with MCP servers for tool access, supports multiple LLM providers (Anthropic, OpenAI, Google, local models), and includes durable execution features like Kanban boards and persistent goals.

This skill covers production deployment, multi-platform configuration, cost optimization, security hardening, skill creation, and troubleshooting based on the OnlyTerp/hermes-optimization-guide repository.

Installation

Quick Local Setup (5 minutes)

# Install Hermes (requires Node.js 18+)
npm install -g @nousresearch/hermes-agent

# Initialize config directory
hermes init

# Start interactive setup
hermes configure

Production VPS Setup (One Command)

For Debian 12 / Ubuntu 24.04:

curl -sSL https://raw.githubusercontent.com/OnlyTerp/hermes-optimization-guide/main/scripts/vps-bootstrap.sh | sudo bash

This installs Hermes, Node.js, Caddy reverse proxy, UFW firewall, fail2ban, creates a hermes user, sets up systemd services, and symlinks all guide skills.

Manual Installation

# Install dependencies
sudo apt update && sudo apt install -y nodejs npm git curl

# Install Hermes globally
npm install -g @nousresearch/hermes-agent

# Create hermes user (production)
sudo useradd -r -m -d /home/hermes -s /bin/bash hermes

# Initialize config
sudo -u hermes hermes init

Durable Execution Features

Kanban Boards (v0.13+)

tenacity:
  kanban:
    enabled: true
    boards:
      - name: development
        lanes:
          - todo
          - in_progress
          - review
          - done
        heartbeat_interval: 60
        retry_budget: 3

    directory: ~/.hermes/checkpoints
    max_size_mb: 500
    pruning:
      enabled: true
      keep_last_n: 10

Usage:

User: "Add feature X to project Y and deploy"
Agent creates Kanban card → moves through lanes → reports status

Persistent Goals

/goal set "Deploy the new API endpoint to production"
/goal list
/goal pause goal_abc123
/goal resume goal_abc123
/goal clear goal_abc123

Goals persist across sessions and keep the agent focused until completion.

Troubleshooting

Common Issues

1. "Cannot find module '@nousresearch/hermes-agent'"

# Reinstall globally
npm uninstall -g @nousresearch/hermes-agent
npm install -g @nousresearch/hermes-agent

# Or use npx
npx @nousresearch/hermes-agent

2. Telegram bot not responding

# Check token validity
curl https://api.telegram.org/bot${TELEGRAM_BOT_TOKEN}/getMe

# Verify webhook isn't set (conflicts with polling)
curl https://api.telegram.org/bot${TELEGRAM_BOT_TOKEN}/deleteWebhook

# Check logs
DEBUG=hermes:telegram hermes daemon

3. MCP server connection fails

# Test server directly
npx @modelcontextprotocol/inspector npx -y @modelcontextprotocol/server-filesystem /tmp

# Check permissions
ls -la ~/.hermes/mcp-servers/

# Verify environment variables
env | grep -E 'GITHUB|BRAVE|DATABASE'

4. Out of memory errors

# Reduce context window
providers:
  anthropic:
    max_tokens: 2048  # Down from 4096
    
# Enable context compression
memory:
  compression:
    enabled: true
    target_tokens: 4000

5. High costs

# Check token usage
hermes stats

# Enable cost-optimized routing
models:
  router:
    strategy: cost_optimized

# Use local models for simple tasks
providers:
  lm_studio:
    default_model: qwen-2.5-coder-32b-instruct

6. Skills not loading

# Verify directory
ls -la ~/.hermes/skills/

# Check skill syntax
hermes validate ~/.hermes/skills/my-skill.md

# Force reload
hermes --reload-skills

Debug Mode

# Full debug output
DEBUG=hermes:* hermes daemon

# Specific subsystems
DEBUG=hermes:telegram,hermes:mcp hermes daemon

# Save debug logs
DEBUG=hermes:* hermes daemon 2>&1 | tee debug.log

Validation Commands

# Validate config
hermes validate

# Test provider connectivity
hermes test-providers

# Check MCP servers
hermes mcp list

# Verify skills
hermes skills validate-all

Real-World Patterns

Pattern 1: Multi-Model Routing

# Use cheap models for simple tasks, premium for complex
models:
  router:
    enabled: true
    rules:
      - if: "token_count < 1000 and !contains(user_input, 'code')"
        use: cerebras  # $0.60/1M tokens
      - if: "contains(user_input, 'write code')"
        use: claude_sonnet
      - if: "contains(user_input, 'analyze image')"
        use: gemini_flash
      - default: claude_haiku

Pattern 2: Secure Webhook Handler

gateways:
  webhook:
    enabled: true
    port: 3001
    path: /webhook
    secret: ${WEBHOOK_SECRET}
    handlers:
      github:
        events:
          - push
          - pull_request
        action: "trigger_skill:github-pr-reviewer"
      stripe:
        verify_signature: true
        action: "trigger_skill:payment-processor"

Pattern 3: Automated Code Review

cron:
  jobs:
    - name: review_prs
      schedule: "0 */2 * * *"  # Every 2 hours
      command: "hermes chat 'Review open GitHub PRs in repo org/project'"
      provider: anthropic
      model: claude-3-5-sonnet-20241022
      
skills:
  # Link github-pr-reviewer.md skill

Pattern 4: Cost-Optimized Local First

models:
  router:
    strategy: local_first
    fallback_on_error: true
    
providers:
  lm_studio:
    endpoint: http://localhost:1234/v1
    default_model: qwen-2.5-coder-32b-instruct
    timeout: 60000
    
  anthropic:  # Fallback for complex tasks
    api_key: ${ANTHROPIC_API_KEY}
    default_model: claude-3-5-haiku-20241022

Pattern 5: Multi-Platform Broadcast

# Send message to all platforms
hermes broadcast "System maintenance in 10 minutes"

# Platform-specific routing in config.yaml
gateways:
  telegram:
    broadcast_channels:
      - "@myteamupdates"
  discord:
    broadcast_channels:
      - "1234567890"  # Channel ID
  slack:
    broadcast_channels:
      - "#general"
