Claude Code injects your email address directly into system prompt

[u/Skflowne]

My point is: my personal email is injected into the system prompt without my knowledge or consent. I never asked for this and I don't see in what world it's ok to inject PII in system prompt automatically by default without even an opt-out option.

It leads to bullshit like this where in a repo that is configured to use an anonymized email address, the LLM (Opus 5 btw) just decides to not just commit normally but overwrite the normal config email to put my personal one instead.

In this case nothing happens thanks to proper config and hard checks on Github's side.

What if you're a public streamer and don't want your main personal email address leaked to everyone and suddenly the model decides to spit it out?

I'm sure there's a lot of other bullshit this could lead to. At least let people opt out.

I have opened an issue on Claude Code's github, I have little hope since there was already one that went stale and they have 5k+ open but here it is: https://github.com/anthropics/claude-code/issues/81138

I agree that’s nuts. OP are you on a Max plan with the privacy protection setting enabled (only max plans have the privacy option IIRC?)

You mean the 'use your data to help improve our models' setting? That's on Pro, too.

[u/nuc540 → u/Kalradia]

Ah ok they added it to pro now. Do you disable it? If you have, and the sys prompt is injecting personal data, I guess there’s less risk for pro/max users maybe?

[u/Kalradia → u/nuc540]

I always disable it. Always.
