AGENTS.md AGENTS.md is a simple, open format for guiding coding agents. Think of it as a README for agents.

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 😀

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.

I had to work hard to help Claude do a good job, but apparently, it enjoyed the experience 🤣

Symfony 20 year! This year, Symfony celebrates its 20 year anniversary. Let’s dive into some statistics of years of making web development history.

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

Symfony 7.4 brings a cleaner way to define console inputs: command arguments and options can now be mapped directly to PHP classes and enums using attributes like `#[MapInput]`, `#[Argument]`, and `#[Option]`.

Type-safe, structured input for your CLI commands 🎉🍕🥓
