Instead they've built 'software factories': teams of specialized agents that triage issues, reproduce bugs, implement fixes, and review changes before a human merges. Vercel reports its factory now authors 25-35% of merged PRs and closes 70-80% of issues within four weeks. Astro's auto-triage system, built after five years of unmanageable backlog, inspired creator Fred Schott to build Flue, which auto-converts every external PR into an issue or discussion. tldraw's Steve Ruiz and Ghostty creator Mitchell Hashimoto go further, suggesting large open source projects may close contributions entirely, redirecting community involvement toward reporting, discussion, and perspective rather than code. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why is Vercel's AI SDK project rejecting external pull requests now? Vercel built a 'software factory' of specialized AI agents to triage, reproduce, fix, and review issues instead of relying on community-submitted PRs, many of which were AI-generated and untrustworthy. The system was deployed after the project accumulated over 1,000 open issues and nearly 800 pull requests by late June. Within four weeks, the factory authored 25-35% of merged PRs and closed 70-80% of issues. _Anyone weighing agent-driven maintenance against traditional PR review can follow this shift on daily.dev._ ### What does the Flue project do when someone submits an external pull request? Flue automatically closes every external pull request and converts it into either an issue or a discussion instead of reviewing the code directly. Bug reports and fix proposals become issues, while feature requests become discussions, after which the team uses its own expertise plus top LLMs to decide what to pursue, then deploys agents for research, design, and implementation. _Contributors adjusting their workflow around agent-first maintainers can track these policy shifts on daily.dev._ ### Does tldraw accept community pull requests? No, tldraw automatically closes external pull requests, a policy creator Steve Ruiz announced and later reiterated, citing changes in how the team codes with more agents, evolving social norms around public contribution, and code security concerns. tldraw still accepts community input in the form of bug reports, discussion, and perspective, just not direct code contributions. _Developers deciding how to engage with agent-managed open source projects can follow these policy changes on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@kartiknvj** · 2 upvotes > The software-factory framing lands, but that 25-35% of merged PRs only works because a human still reviews before merge. I'd be curious how they stop the triage agents from confidently reproducing a bug that isn't real, since a false repro wastes more time than a drive-by PR. Are the fix and review agents scored on anything beyond "tests pass"? **@agustinbarrientos** · 0 upvotes > I'd let external contributors write the failing test while maintainers keep implementation inside the factory. That preserves a path into the project without turning every AI-generated patch into review debt. ## Similar posts on daily.dev - [Open source maintainers are drowning in AI-generated pull requests.
