Ask HN: Do you comment on a code/Markdown files, then get your agent to reread?

I'm building a cli driven markdown reader called SDocs (https://sdocs.dev / https://github.com/espressoplease/SDocs). I am considering adding a "leave a comment" feature, where you can make a comment inline on the markdown file and easily get the feedback back to your agent.

This is not something I normally do, so I was wondering if it's a common use case I should build for.

Thank you for any thoughts
