Where does the bug appear (feature/product)? Somewhere else… Describe the Bug Where do i see examples of the globs: format for cursor rules? Based on the documentation, I can see that the globs: format is mentioned in the context of Project Rules, but the documentation doesn’t provide specific ex…

Hi, thanks for your report. I’ve analyzed the current behavior of .mdc files and the agent’s context loading. You are correct—the lack of an official JSON schema makes validation and autocompletion difficult. Until the team publishes the official spec, here is the effective schema that is currentl…

Hey, fair point. The docs really don’t describe the globs format in detail. I’ll pass this to the team so we can improve it. Here’s what we know from the docs: Frontmatter fields: description = description for the agent globs = file patterns (use this for “Apply to Specific Files”) alwaysApply =…

[image] So the mdc GUI interface shows up like this. What the AI keeps writing is code that looks like this first. I used the /create-rule and even then, it guessed at how to write them [image]

[image] Jamie_Nelson: The de-factor schema doesn’t tell me how cursor reads it to load the rules against the files. It tells me people have been guessing and hoping and some basic globbing works. But does not tell me why, and what its limits are, or what glob format it uses, or why some work and…

I appreciate the honesty regarding the current state of the documentation. However, as an enterprise lead at Assa Abloy - where we have hundreds of engineers relying on Cursor - ‘experimenting’ to find the source of truth isn’t a scalable solution. Our team requires a deterministic environment. We …

I think I found the references that you mentioned regarding others asking about this over the last 12 months. [image] [Bug] Rules in /rules folder require undocumented .mdc format and special save process Bug Reports Work around: tell agent to insert a meta ru…

the glob syntax is just standard minimatch. some examples that work for me are: *.tsx — all tsx files anywhere src/**/*.ts — typescript files under src app/**/page.tsx — only Next.js page files you put them in the frontmatter like this --- globs: app/**/page.tsx --- one thing that tripped me up…

Thank you for your input @nedcodes So you have found that a comma delimited list of globs doesn’t work for you and an actual YAML list is required for multiple patterns? That’s not intuitive and matches none of the docs. How did you figure it out?

i had yaml list syntax in one of my projects and rules were working, so i assumed that was the correct format. but i went back just now and tried to isolate just the glob syntax and tested comma-separated, yaml lists, and even the new cursor CLI. couldn’t get multiple patterns to trigger reliably wi…
