Show HN: Keyhole – Share secrets with your AI agents

I had the idea for Keyhole while bootstrapping a bunch of small services and apps. I'm trying to prototype fast, and sometimes these need a variety of secrets. I use Doppler to remove myself from the loop, but once in a while I still need to provide a secret. AI agents will suggest you rotate a secret once it's been shared in a chat. I thought it would be a cool experience to let your agent ask for secrets without having them dumped in the context. The agent runs a command, a form pops up in my browser, and I paste the key.

Env vars work. But anything that allows me to stay focused is a win. This isn't perfect, but it solves something for me, and hopefully others will find it useful too.

There's nothing crazy cool technically here, as one might expect; I vibe-coded the whole thing. But I think it's a great UX/DX.
