Plannotator Inbox arrives as a local preview

The preview groups agent questions, files and reviews into one local window; replies return to the asking session. It listens on loopback and stores data locally. Claude Code’s mod exposes its Inbox tool by default; Pi and OpenCode 2 require an explicit opt-in. Test the question/reply lifecycle before relying on it for unattended work. ⁴

Relevant to: Developers coordinating several agent sessions that need human decisions.
