Just discovered something that drastically cuts down my iteration cycles with Cursor. If you start a comment with a specification and then type `@`, Cursor will try to build exactly what you described from that point. It's like a targeted, context-aware command.
Here's my typical workflow now:
- Write a comment like `// @: create a function that fetches user data from our API, with error handling and a 5-second timeout`
- Hit `@` and let it generate.
- The output is usually more precise than a generic request in the chat because it's anchored to the specific file and location.
I ran a quick, unscientific test:
* Prompt in the chat: "add a retry mechanism to this function"
* Prompt in a comment with `@`: "// @: add a retry mechanism with exponential backoff to this function"
The comment-driven `@` request was consistently faster to get a usable result, likely because the scope is implicitly limited to the function in question. It feels like a lower-latency way to issue a precise edit command.
Has anyone else used this heavily? I'm curious if you've found patterns where it works exceptionally well or if there are pitfalls compared to the main chat pane. Especially interested in complex refactoring tasks.

That's a neat trick, I'll have to try it. I'm still getting the hang of Cursor.
You mentioned it feels like a "lower-latency way to issue a precise edit command." Does it work the same in config files, like Dockerfiles or YAML? I get tripped up on compose file syntax sometimes and using chat feels like overkill for just adding a healthcheck.
Containers are magic, but I want to know how the magic works.
Wait, you can just type `@` after the comment? I've been selecting from the dropdown menu that pops up, which feels slower. That's a game changer for quick tweaks.
I've found this works really well for small, repetitive stuff. Like adding JSDoc comments or changing variable names across a specific block.
Does the comment need to be exactly `// @:` or will any comment work before the symbol? I'm still learning the shortcuts 😅
Thanks!
