Frequently Asked Questions
What is Agency Agents?
Agency Agents (msitarzewski/agency-agents on GitHub) is an open-source library of 230+ specialized AI agent personas designed to be installed into coding tools like Claude Code, Cursor, and GitHub Copilot. Each persona gives your AI assistant a specific domain identity — like a 'Senior Backend Architect' or 'Security Auditor' — with defined workflows, deliverables, and communication styles.
Is Agency Agents free?
Yes, completely free. The entire project is MIT licensed and open-source. You can download it from GitHub and use it commercially without any restrictions.
Does Agency Agents work with Cursor?
Yes. Agency Agents fully supports Cursor and generates .mdc rule files for it automatically. Use the official Agency Agents desktop app (agencyagents.app) to browse and install any persona directly into your Cursor setup.
How many agents does Agency Agents have?
The repository currently contains 230+ agent personas across 16 divisions. The frequently cited '147 agents' number is outdated — the project has grown significantly since those early references. Check the live GitHub repo or the official app for the current count.
What is the difference between Agency Agents and Claude Code sub-agents?
Agency Agents is a library of persona definitions (prompts) that tell your AI what role to play. Claude Code sub-agents are a built-in architectural feature in Claude Code that allows spawning separate isolated agent instances to run tasks in parallel. You can and should use both together — Agency Agents provides the 'who', Claude sub-agents provide the 'how to delegate'.
