What Agency Os is
Agency Os is a plugin published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”
A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.
Installing Agency Os adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.
How to install Agency Os
Claude Code
- Add the repository as a plugin marketplace: claude plugin marketplace add jeremylongshore/tons-of-skills-marketplace
- Install the plugin: claude plugin install agency-os@<marketplace-name>, using the marketplace name from the repository's .claude-plugin/marketplace.json.
- Restart the session if the new skills or commands don't appear straight away.
Claude Cowork
- Open Customize → Plugins and choose Add marketplace.
- Enter jeremylongshore/tons-of-skills-marketplace (the owner/repo shorthand works for GitHub).

> Run your work like an AI agency, from a single Notion board.
Turn Notion into the dashboard of your own AI agency. You discuss ideas with the agent, it clarifies scope and writes the plan into Notion, you approve, and agents ship the work in parallel - with result links back on the row.
What you get
- Agent-driven planning. Talk through an idea in plain English. The agent asks questions, carves work into tasks and subtasks, sets dependencies, and writes the plan to Notion.
- One board for everything. Ideas, tasks, decisions, and finished work in one place.
- Parallel execution. Agents run Exec=Agent rows in parallel, respecting dependency order. Right model for the job - fast models for mechanical work, bigger ones for judgment tasks.
- Operator-gated. Nothing dispatches autonomously. Every run is opt-in; the board is honest about what's queued and why.
Quick Start
- Install the plugin from your terminal: ccpi install agency-os
- Duplicate the public Notion template into your workspace.
- Create a Notion integration at https://www.notion.so/my-integrations and share it with the duplicated page.
- Add NOTION_KEY=secret_... to your .env (and ensure .env is in your .gitignore).
- Restart your claude session and run /agency-os scaffold in the chat to wire the board.

Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
