Does Cursor retain anything you've corrected between sessions?

I keep running into the same thing: I correct Cursor mid-session — 'don't force-push,' 'always run tests before committing,' 'use the existing helper, don't write a new one' — and it listens. That session is great.

Next session? Groundhog Day. Same force-push. Same skipped tests. Same duplicate helper.

What finally worked for me was dead simple: thumbs down the mistake. Not just a mental note — an actual structured signal: what went wrong, what to change. The system turns that thumbs-down into a prevention rule, and the agent is physically blocked from repeating it next time.

Thumbs-up works too — it reinforces the behavior you want to keep. Over time, the good patterns strengthen and the bad ones literally can't execute.

No prompt engineering. No manually updating .cursorrules every session. You just react with thumbs-up or thumbs-down as you work, and the enforcement builds itself from your feedback.

The agent literally can't repeat a known mistake once a rule exists for it.

Curious how others are handling cross-session reliability. Are .cursorrules and manual prompting enough for your workflow, or have you found something that sticks better?
