Ask HN: How do you manage bad artifacts?

We use a repo called business-ops that has read-only codebase access, dropbox access, and g-suite access, along with all our brand/sales/marketing stuff.

We use Cursor to work in here mostly on biz-dev, non-technical proejcts.

A lot of what is generated is ideation, and 75% or more is unused. But it gets stored as MD files regardless. So future agents use some of this as context for thinking about whatever the new session is exploring. Which sucks and means it gets more noisy over time.

Anyone have a good method for cleaning up old artifacts automatically that doesnt involve manually deleting MD files or text inside MD files?
