What is Paperclip?

Paperclip is an open-source orchestration framework for building “zero-human companies” by hiring and managing teams of AI agents. It handles content, social media distribution, marketing, dev, QA, and more from a single dashboard.

👥

Agent Teams

Paperclip manages teams of AI agents that work together. Assign a content agent, a scheduling agent, and a review agent to your social media workflow.

📊

Single Dashboard

Monitor all your AI agents and their social media tasks from one unified dashboard. Track posts, schedules, and performance in real time.

⚙

Orchestration

Schedule recurring tasks with cron jobs. Paperclip can post your Slack messages on a schedule without you having to ask each time.

How Postiz Works with Paperclip

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

✓Install Postiz Agent and set your POSTIZ_API_KEY
✓Paperclip discovers Postiz through tool integration
✓Assign Postiz commands to specialized agents in your team
✓Orchestrate multi-step workflows with approval chains
✓Monitor everything from the Paperclip dashboard

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 Slack integration, identifies the correct channel, and sends your message.

Claude Code

> Post a deployment update to #engineering
  on Slack

Claude will automatically run:
  postiz integrations:list
  postiz posts:create \
    -c "Deployment v2.4.1 complete" \
    --settings '{"channel":"C12345"}' \
    -i "slack-id"

Slack + Other Platforms

Post the same announcement to Slack and other platforms in a single command. Each platform gets its own settings.

Terminal

# Post an announcement to Slack and Discord simultaneously
postiz posts:create \
  -c "New feature released: dark mode is here!" \
  -s "2025-01-15T09:00:00Z" \
  --settings '{"channel":"C12345"}' \
  -i "slack-id,discord-id"

# Batch schedule a week of Slack updates
for day in 1 2 3 4 5; do
  postiz posts:create \
    -c "Daily standup reminder - Day $day" \
    -s "2025-03-0${day}T09:00:00Z" \
    --settings '{"channel":"C12345"}' \
    -i "slack-id"
done
