Symfony Language Tools stopped taking patches

Symfony’s new Language Tools repository closed its pull request tab. Contributors now start with an issue instead. Maintainers turn selected issues into code, usually with a coding agent doing much of the implementation work.

Fabien’s reasoning is what stuck with me. An agent can usually produce the implementation quickly; understanding the problem is what actually takes time, and that understanding is usually deepest in whoever hit the bug. As a maintainer I recognise that trade immediately. A precise bug report, naming the exact editor and version, plus whatever local configuration mattered, has always been worth more to me than a diff I first have to unpick to find the real problem underneath it.

It still makes me a little sad. Contribution is what makes open source communities work, and a merged pull request still means something: your name in the changelog, proof you were part of it.

The part I keep circling back to isn’t really the pull request tab, though. It’s responsibility. Making code this cheap to produce doesn’t automatically make anyone responsible for seeing it through. I see both sides of that already in symfony/ai: pull requests that are obviously AI-generated, including some of mine, where the person behind them stays in the conversation and sees the concept through, and others that are fire-and-forget, oversized, dropped as if writing the diff were the whole job.

Closing pull requests to outsiders doesn’t remove that responsibility problem. It moves more of it onto the maintainer. I think I would rather keep contributors in the loop: issue first, then a pull request once someone is actually taking responsibility for seeing it through.

What I’m less sure about is how either model scales. If contributors provide the problem and maintainers own the whole path from there to implementation, the bottleneck moves away from typing code and toward understanding, prioritising and validating what should actually be built.

For a repository built with agents from the start, closing the pull request tab might still be an honest description of where the work has moved.
