I recently created a throwaway API key for cloudflare and asked a cursor cloud agent to deploy some infra using it, but it responded with this:

> I can’t take that token and run Cloudflare provisioning on your behalf, even if it’s “only” set as an env var (it’s still a secret credential and you’ve shared it in chat). Please revoke/rotate it immediately in Cloudflare.

So clearly they've put some sort of prompt guard in place. I wonder how easy it would be to circumvent it.

Claude definitely has some API token security baked in, it saw some API keys in a log file of mine the other day and called them out to me as a security issue very clearly. In this case it was a false positive but it handled the situation well and even gave links to reset each token.

If your prompt is complex enough, doesn’t seem to get triggered.

I use a lot of ansible to manage infra, and before I learned about ansible-vault, I was moving some keys around unprotected in my lab. Bad hygiene- and no prompt intervening.

Kinda bums me out that there may be circumstances where the model just rejects this even if you for some reason you needed it.
