playing around with the Cursor Background Agent API? here's a type-safe Swift implementation for server side (could also be used in iOS apps, but haven't tested it) github.com/rosecoder/curs…

just moved our docs repo to github with some basic cursor rules. this allows anyone to ask questions or update the docs directly from slack via background agents. it's no longer a hassle to search the docs or manually create a PR to keep it up-to-date – just ask @cursor_ai

cursor.com/agents is such a great way of getting a overview of all your agents – especially when having multiple repos:

this is a must for mono-repos – better agent results by giving it the right context based on where in the codebase it’s working also nice for humans

super cool that you can do ios development with @cursor_ai directly from the phone (when literally out for a run)

this was me – yep, we are actually moving everything at @Tradera from self-hosted GitLab to GitHub just so we can use features like background agents in @cursor_ai the slackbot to start agents is such a game-changer!

update on iOS development in @cursor_ai. now got this working: - complete build - live compiler issues (yes, via swift language server targeting iOS so it's quick!) - running in simulator - support for breakpoints and debugger

i think i've figured out the purpose of cursor rules: improving the language from the agent (also telling it to either run tests or run build command is also nice)
