pull requests

System76 has announced that its COSMIC desktop projects will no longer accept code submissions containing LLM-generated content. The Linux hardware and software company says contributions including material produced by large language models will be rejected in pull requests. The move makes System76 one of the more prominent open-source developers to explicitly bar AI-written code, reflecting frustration among maintainers with low-quality AI-assisted contributions.

Orbi, an AI coding agent, reportedly takes a GitHub issue and returns a reviewed, merged pull request, with one agent writing the fix and another handling review. A follow-up post examining the system's harness asks what its reviewer missed, suggesting developers are scrutinising how reliable the automated pipeline is. The discussion is drawing interest from the open-source and AI engineering communities.

A user has raised an improvement request for the Mastodon iPhone app, complaining that refreshing the feed requires an awkwardly long pull-down gesture. When reaching the end of the timeline, the swipe needed to load new messages is too tall to reach comfortably with a thumb, forcing users to shift their grip or use another finger. The feedback adds to ongoing discussion about small usability issues in the decentralized social network's mobile apps.

A developer is offering a paid human second-pass review of AI-generated pull requests, and says they reviewed three AI-written PRs from public repositories before pitching the service, which they call Riven Desk. The idea taps into growing concern that AI-written code is being merged without careful human scrutiny. Commenters in programming and engineering communities appear engaged with the question of how much review AI code actually needs.

System76, the Linux hardware and software company, will no longer accept LLM-generated content in pull requests for its COSMIC desktop environment project. The move means code submissions flagged as AI-generated will be rejected. The decision reflects a broader debate in open-source development, where maintainers are increasingly pushing back on low-quality or unreviewable AI-generated contributions flooding their queues.

A week of releases across the Linux ecosystem: OpenMandriva ROME 26.09 and Nitrux 7.0 shipped, Ubuntu 26.10 entered beta, and updated versions of Firefox 157, Wine 11.19 and Git 2.56 landed. In project news, the COSMIC desktop has stopped accepting AI-generated pull requests, a decision drawing attention among developers. The roundup bundles the main open-source headlines from the past week.

Developers are debating how to handle pull requests written with the help of AI coding agents. The discussion, circulating among programmers and engineering managers, asks how thoroughly reviewers should scrutinise such contributions, weighing whether agent-written code deserves the same depth of review as human work and what that means for team standards, trust and inclusive review culture.

Bevy contributor Alice Cecile is working another late night on the Bevy merge train, the process of reviewing and landing community-approved pull requests into the open-source Rust game engine. She notes flexible schedules are a mixed blessing and is writing a series of free-form posts about the realities of open-source engine development.

A software developer has added a continuous integration workflow to their open-source project that automatically rejects pull requests containing commits signed by major AI agents or marked as AI-assisted. The check is shared as a reusable workflow in a separate repository so the blocklists and regex patterns can be updated centrally across projects.
