What is Hermes Agent?

Hermes Agent is an open-source AI agent framework by Nous Research — “the agent that grows with you.” It's a flexible platform for building and running AI agents that can execute real-world tasks.

🌱

Grows With You

Hermes Agent learns and adapts to your workflows over time. The more you use it, the better it understands your social media strategy and content style.

🔧

Open-Source Framework

Built by Nous Research, Hermes Agent is fully open-source. Customize and extend it to fit your exact social media automation needs.

⚡

Tool Execution

Schedule recurring tasks with cron jobs. Hermes Agent can publish your Dev.to articles on a schedule without you having to ask each time.

How Postiz Works with Hermes Agent

When you install Postiz Agent globally, Hermes Agent automatically discovers it by reading the bundled SKILL.md file. This file tells Hermes Agent what commands are available, what environment variables are needed, and how to compose Dev.to articles with the right settings.

✓Install Postiz Agent globally with npx skills add
✓Hermes Agent discovers Postiz through tool execution framework
✓POSTIZ_API_KEY must be set in environment
✓All Postiz commands become available as agent tools
✓Works with any compatible LLM backend

Install Postiz

# Install the Postiz skill
npx skills add gitroomhq/postiz-agent

# Set your API key
export POSTIZ_API_KEY=your_api_key

# Hermes Agent discovers Postiz

Dev.to Publishing with Hermes Agent

Message Hermes Agent from any platform — it reads the Postiz skill, discovers your Dev.to integration, and handles the entire publishing workflow autonomously.

🧠

From Any Chat App

Hermes Agent reads Postiz commands throu...

Send a message to Hermes Agent from your favorite chat app. It runs as a persistent daemon on your machine, so it picks up your message, discovers your Dev.to account via Postiz, formats the article, and publishes it — all while you go about your day.

Hermes Agent

You: Post to Dev.to about our new
  feature launch, schedule for tomorrow
  at 9am

Hermes: I'll handle that! Let me:
  1. Find your Dev.to integration
  2. Compose your post content
  3. Schedule for tomorrow 9:00 AM

  Done! Post scheduled successfully.
  Post ID: abc-123

🧠

Scheduled & Proactive

Hermes Agent supports scheduled tas...

Hermes Agent supports cron-based heartbeat tasks. Set up a recurring job that checks a folder for new Markdown drafts and publishes them to Dev.to automatically — no manual trigger needed.

hermes-config.yaml

scheduled_tasks:
  - name: daily_social_posts
    schedule: "0 9 * * 1-5"
    prompt: |
      Check ~/content/posts for new
      .txt files. For each one, read
      the content and schedule a post
      to Dev.to for today at noon.
      Move posted files to
      ~/content/published.

Also Works with Claude Code

Postiz Agent works as a CLI tool with any AI agent that can execute shell commands — including Anthropic's Claude Code.

Claude Code

by Anthropic

Claude reads the SKILL.md file to learn all available Postiz commands, then autonomously discovers your Dev.to integration, uploads your cover image, applies tags and organization settings, and publishes the article.

Claude Code

> Publish my React tutorial to Dev.to
  under our org with a cover image,
  tag it with react and webdev

Claude will automatically run:
  postiz integrations:list
  postiz upload ./cover.png
  postiz posts:create \
    -c "$(cat react-tutorial.md)" \
    -s "2025-03-02T09:00:00Z" \
    --settings '{"title":
      "React Tutorial",
      "main_image":{"id":"...",
        "path":"uploaded-url"},
      "organization":"org-id",
      "tags":[...]}' \
    -i "devto-id"

Dev.to + Other Platforms

Publish the same article to Dev.to and other platforms in a single command. Each platform gets its own settings.

Terminal

# Cross-post an article to Dev.to and Medium
postiz posts:create \
  -c "$(cat article.md)" \
  -s "2025-03-01T09:00:00Z" \
  --settings '{
    "title": "Building Real-Time Apps",
    "canonical": "https://myblog.dev/real-time",
    "tags": [
      {"value": "webdev", "label": "Web Dev"},
      {"value": "react", "label": "React"}
    ]
  }' \
  -i "devto-id,medium-id"

# Batch schedule a week of Dev.to articles
for day in 1 2 3 4 5; do
  postiz posts:create \
    -c "$(cat articles/day${day}.md)" \
    -s "2025-03-0${day}T09:00:00Z" \
    --settings '{"title":"Day '"$day"' Dev Tips","tags":[{"value":"tutorial","label":"Tutorial"}]}' \
