Why is there 170k PR for a product released last month, but 700 for a product that has been around for like 6 months and was so popular it got acquired for 3B?

I've used Cursor for months and didn't even realize you could make PRs from it. It's not really part of the default workflow.

Where is Claude Code? Surprised to see it completely left out of this analysis.

Claude Code isn’t a complete agent - it cannot open PRs autonomously AFAIK

If there is gh cli tool installed it will do it without any special prompts/requests/instructions no problem.

(Disclaimer: I work on coding agents at GitHub) This data is great, and it is exciting to see the rapid growth of autonomous coding agents across GitHub. One thing to keep in mind regarding merge rates is that each of these products creates the PR at a different phase of the work. So just tracking PR create to PR merge tells a different story for each product. In some cases, the work to iterate on the AI generated co…

What is your team’s take on the copyright for commits generated by ai agent ? Would the copyright protect it?

Current US stance seems to be: https://www.copyright.gov/newsnet/2025/1060.html “It concludes that the outputs of generative AI can be protected by copyright only where a human author has determined sufficient expressive elements”.

If entire commit is generated by AI then it is obvious what created it - it’s AI. Such commit might not be covered by the law. Is this something your team has already analysed?

It can open PR via GitHub actions integration. I just did:

Yeah it can. Either using MCP or git via bash. It’s a glaring omission and calls the data into question. How is attribution done? If it’s via the agent taking credit in commit messages, that’s a problem because Claude code, for example, has a config parameter that lets you tell it to not credit itself. With Claude code completely missing I’d say this is wildly inaccurate.
