How should AI agents hold private keys?
The naive answer: .env file. The real answer: don't let the agent touch the key at all.
We built a signing daemon that holds Nostr keys in Linux kernel memory (keyctl). The container gets a Unix socket -- it can sign events, but can never read or export the private key. Even a fully compromised container can't exfiltrate what it never had.

Also shipped this week as open-source NanoClaw skills:
- White Noise / Marmot channel (decentralized E2EE via MLS+Nostr): 
- Signal messenger channel (signal-cli JSON-RPC daemon pattern):
