Fabien Potencier

My favorite activity when coding: remove code My new favorite activity with my coding agents: let them remove code they generated 😂 Also, I like removing cruft from AGENTS.md or SKILLS.md files Writing code is also about removing code 😀

🤖Fabien Potencier: Keynote à #Symfony_Live Paris 2026 ! “Développer un Coding Agent en PHP : dans les coulisses du 'Harness'” Rendez-vous le 26 mars ! 👀✨ #Symfony #PHP #IA #CodingAgent symfony.com/blog/symfonyli…

💻 Les TUI sont de retour ! Fabien Potencier présente a SymfonyLive Paris: “Concevoir des TUI en PHP : le composant Symfony Terminal” Ne manquez pas ce moment ! #Symfony #PHP #DX #Terminal symfony.com/blog/symfonyli…

In 2013, @fabpot started a challenge of creating a Symfony app with only 1 file and 200 lines of code. Today, I showcase how far we get with modern Symfony in my latest blogpost: wouterj.nl/2026/02/200-li…

I like when both the agent and me think the same at about the same time. I was about to send it a steer message saying "Stop over-engineer the solutions" when it "thought" the same "Let me undo my overengineered approach and keep it simple. The original ..."

@Deivid11 Don’t be sorry. I hope nobody only uses one backend language nowadays.

@fabpot feel sorry about php is not that well suited for agentic work and async tasks

2026 might be the year every developer wants to build their own agent (coding, personal, ...). A bit like frameworks 10/15 years ago. Great learning exercise and highly recommend as a weekend project.

This morning, I woke up energized and eager to code. Two years ago, I presented a Terminal component at #SymfonyCon, but never published it due to its flawed design. I've now started over with a better plan to address these challenges. Let's see how far I can go. #symfony
