clone-office

1// The plugin's mod. Two things, so the person's office comes to the Claude Code they work in:
2//
3// What waits on them (their clone's questions about colleagues' requests, its permission cards,
4// questions kept for later) shows under the prompt and as a toast when one comes, and /office
5// answers each in Claude Code's own question dialog, as the page or the phone would. It asks the
6// Clone Office app on this computer (its address in app.json in the clone's folder) for that.
7//
8// What colleagues' mini-mes send back later comes into the conversation that asked, once it is
9// idle. A quick answer already came in the tool's own reply; this is for the rest, often because the
10// colleague's mini-me asked its person first. It learns which requests a conversation asked from the
11// tools' replies, keeps them in the plugin's store (so a conversation closed and resumed later still
12// gets its answers), looks at them on the relay every 10 seconds while any is open, and starts a
13// turn with what came. It calls the relay itself: the plugin's own calls to its MCP tools would need
14// the person's leave every time.
