Godot engine cracks down on vibe-coding, now requires genAI disclosures from contributors

The Godot Foundation has announced a new policy cracking down on generative AI use in contributions to the open source Godot game engine. Following a surge of what the foundation calls "low-effort slop" pull requests, maintainers say the problem has become impossible to ignore.

The policy draws a line between acceptable and unacceptable AI use. Small, menial tasks — like find-and-replace operations — are still fine. But vibe-coding, where a contributor asks a bot to generate large chunks of code wholesale, is now firmly discouraged. On top of that, all contributors must disclose any genAI usage going forward. The foundation's blog post explains the core problem bluntly: the effort required to submit a pull request has dropped sharply thanks to AI tools, so the volume of PRs has climbed, while the number of qualified reviewers and the time they have available has stayed exactly the same. Some of the newer "contributors" aren't even human — they're fully automated AI agents submitting code.

Godot matters well beyond its own codebase. It's the engine powering Slay the Spire 2, Buckshot Roulette, The Case of the Golden Idol, and Cruelty Squad, among others, and its popularity surged after Unity torched its own reputation in 2023 by introducing per-install runtime fees that outraged developers. Godot runs almost entirely on volunteer labor, with contributors submitting pull requests that seasoned maintainers then review and approve. That mentorship pipeline — where reviewers invest time in educating new contributors who might eventually become maintainers themselves — is central to how the project sustains itself across generations of developers.

The foundation says AI-generated PRs are particularly demoralizing because that mentorship loop breaks down entirely: feedback given to a bot doesn't train a future maintainer, it just disappears. The community's reaction has been broadly supportive of the new rules, with many long-time contributors pointing out that the pull request backlog had already become a running joke before AI made it worse. What comes next depends on how strictly the disclosure requirement gets enforced and whether the policy actually reduces the flood of low-quality submissions.
