What if you could hire 144 specialists -- engineers, designers, marketers, QA testers, even a "Whimsy Injector" -- and pay them zero salary?
That's what The Agency does. It's a 105,000-star GitHub project by Marcin Sitarzewski that packages 144 AI agent personalities into .md files you can load into any AI coding tool.
Not a SaaS subscription. Not a framework. Just 144 detailed job descriptions that teach AI to act like specialized employees.
12 Departments, 144 Specialists
The Agency organizes agents into 12 divisions, each with clear roles:
| Division | Sample Agents | Best For |
|---|---|---|
| Engineering | Frontend Dev, Backend Architect, DevOps, Sec | |
| urity Engineer | Full-stack dev, infrastructure | |
| Design | UI Designer, Graphic Designer, Accessibility Specialist | Visual design, UX |
| Product | PM, Competitive Analyst, Monetization Strategist | Strategy, roadmapping |
| Marketing | Content Creator, Reddit Builder, Growth Hacker | Content, community |
| Quality | Evidence Collector, Performance Benchmarker, API Tester | Testing, reviews |
| Support | Analytics Reporter, Finance Tracker, Legal Compliance | Operations |
Each agent has a personality, core mission, critical rules, deliverables, workflow, and success metrics.
What Makes It Different From Prompt Libraries
Most prompt collections give you one-liners. The Agency gives you employees:
"I don't just test your code — I default to finding 3-5 issues and demand visual evidence for everything." — Evidence Collector
"You're not doing marketing on Reddit. You're becoming a valuable community member who happens to represent a brand." — Reddit Community Builder
"Every playful element must serve a functional or emotional purpose. Design delight to enhance, never distract." — Whimsy Injector
This depth is what separates it from generic prompt packs.

One Pattern I'm Stealing Immediately
The Evidence Collector agent. It defaults to finding 3-5 issues and demands visual proof. I'm adding this to my quality pipeline.
What This Means for Solo Devs
If you're a one-person team, The Agency gives you specialists. You don't need to be good at everything -- just pick the right agents.
