> Something that is supposed to be very private and secure

Not sure how using an LLM for development of the tool has any affect on this. From a security perspective, I think that would've had more validity a year or two ago, but these days, I'd argue LLMs practice better security in generated code on average than a normal developer.

From the privacy angle, I have no idea how having an AGENTS.md (for development purposes) has any impact on privacy.

I don't want to "burn [your] karma to the ground", I just want to understand this angle, because I'm not sure I see how it applies.
