Iii Channels

This is WebSocket-backed binary streaming for Claude Code workers, basically Unix pipes for distributed functions. You create a channel, get writer/reader pairs, then pass serializable refs to other workers (even across languages, so Python can write to Rust). Data chunks at 64KB frames. The architecture is clean: one worker calls createChannel(), sends the ref via a function payload, and the engine brokers the connection. You'd reach for this when you need to stream large datasets or real-time data between workers without round-tripping through your main process. Not every worker needs it, but when you do need cross-worker streaming, this beats batching JSON payloads.
