What this actually is
The Agency is a public GitHub repository holding a cast of AI specialists. Not prompt templates, not a starter pack. Each one is a written character with a name, a domain, a working process and a stated definition of done, and each one drops into Claude Code as an agent you can call by name.
The reason it is worth your time is not the count. It is that somebody has already done the boring half of the work: deciding what a Reddit Community Builder should care about that a Frontend Developer should not, and writing that difference down.
- Repo: github.com/msitarzewski/agency-agents
- Over 149,000 stars and 24,000 forks, MIT licensed, free
- 273 agents counted across 18 divisions
- A native desktop app for macOS, Windows and Linux that installs them for you
- Installs into Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot, Windsurf, Qwen, OpenCode and Osaurus
The mistake almost everyone makes on day one
They install all 273. Do not.
An agent roster is a selection problem before it is a capability problem. When you type a request, something has to decide which specialist should answer it, and that decision gets worse as the candidate list grows. Handing the selector 273 options when your work only ever touches six is not thoroughness, it is noise you have to wade through every single session.
There is a second reason, and it is more concrete. OpenCode's runtime currently registers only about 119 agents and silently drops the rest, which the repo documents in its own README. A full install on that harness means a roster where some agents exist and some quietly do not, with nothing telling you which is which.
Install the two or three divisions that match what you actually ship. Add a fourth when a real task has no match, never in advance
The 18 divisions, and roughly what sits in each
This is the map nobody publishes, and it is the thing that makes the roster navigable. Counted from the repo's own tables.
- Engineering, 59 agents. The largest by a wide margin. Frontend, backend, mobile, infrastructure, refactoring.
- Specialized, 57. The catch-all, and worth browsing rather than assuming.
- Marketing, 36. Content, community, SEO, lifecycle, and the Reddit builder.
- Game Development, 21. Systems, level design, economy, live ops.
- GIS, 13. Geospatial, mapping, remote sensing.
- Security, 12. Auditing, threat modelling, compliance.
- Design, 10 and Sales, 10.
- Testing, 9. Unit, integration, load, and test strategy.
- Paid Media, 7 and Project Management, 7.
- Support, 6. Spatial Computing, 6. Academic, 6.
- Product, 5. Finance, 5. Healthcare, 3. Research, 1.
If you build software, Engineering plus Testing plus Security is a complete working set and it is 80 agents, not 273. If you make content, Marketing plus Design plus Paid Media is 53. Pick the row that describes your week.
