Vibivibi: End-to-End Encrypted Sharing of Coding Agent Sessions

About

Vibivibi is a CLI named vibi that finds locally stored sessions from coding agents (Claude Code, Codex CLI, OpenCode, Pi), encrypts one on the user's machine and uploads it. Running vibi pull on another machine restores the session where the agent expects it so it can be resumed, and vibi push can send a session to another person by email. Encryption uses per-session-version keys wrapped per recipient with X25519, HKDF and AES-256-GCM, so the server cannot read session content. It still sees account emails, public keys, machine names, sizes, timestamps and sender-recipient relationships.
