There's a free, open project making the rounds right now called agency-agents. Someone started it after a Reddit thread asked a simple question: what if your AI assistant had an actual specialty, instead of just being a generalist who knows a bit of everything?
The result is a collection of over 100 AI "characters" — each one tuned to a specific job. Not just a developer, but a frontend developer with opinions about user experience. Not just a marketer, but a Reddit community manager who sounds like a real person in a comment thread. A QA tester who looks for problems. A brand guardian who says no when something feels off.
You install it once and it figures out which AI tools you already use — things like Claude or Copilot — then quietly sets everything up for you.
The part that made us stop and think: you can run eight of these agents at once. One session, one project, and you walk away with a market validation, a build plan, and a go-to-market strategy. That's normally a week of consulting.
Most people use AI like a very fast intern — good for drafts, fine for summaries. This is closer to having a small team that actually pushes back, specialises, and delivers something finished.
If you're a founder doing everything yourself, or a small team stretching thin, this changes the texture of what's possible in a single afternoon.
AI agent — An AI that doesn't just answer questions, but takes on a role and works toward a goal. Less like a search engine, more like a colleague.
Persona — In this context, a set of instructions that gives the AI a personality, a specialty, and a way of working. It's what makes one agent feel like a strategist and another like a sceptical QA tester.
Open source / MIT licensed — Anyone can use it, build on it, or use it in a commercial project for free. No permission needed, no fees.
Worth thinking about: what specialist on your team is missing most right now? There's probably an agent here that fills it.
