Start a NEW task in the local Qwen Code agent — a separate CLI coding agent with its own file/shell tools and its own context window. Blocks until qwen settles, then returns only its final result plus stats, prefixed [session: ]; continue that session later with qwen_reply. Good for: a second opinion from a different model, work kept out of this context, or parallel investigation. Caution: with approval_mode 'yolo' (the server default) qwen edits files and runs shell commands as your user inside cwd without asking. For analysis-only work pass an allowed_tools list or approval_mode 'plan'.

Send a new turn to an existing qwen session that is not executing right now — including one that timed out or was cancelled: the session survives in qwen's own store, so resume it here instead of restarting with qwen. qwen still has its prior turns (but never this conversation), so the follow-up can be short. Survives restarts of this server. For a turn still running under 'stream', use qwen_send instead.

List the models this qwen installation can actually reach right now — id, label, capabilities, context window — read live from the CLI over its control protocol. Use it to pick a model value for qwen / qwen_reply. Starts no task.

Deliver a message into a qwen turn that is executing right now. Works only on runs started with transport 'stream' — 'print' runs cannot be reached, and a session that already finished takes qwen_reply, not qwen_send. Returns immediately; qwen's reaction appears in the answer of the qwen/qwen_reply call still waiting on that turn. qwen_running lists reachable sessions. Note: the adapter reports the first result envelope; a follow_up queued behind the current turn is delivered but its answer is not awaited by the original call.

List qwen turns executing at this moment — the ones qwen_send can reach — with session id, working directory, elapsed time, and messages already sent in. Only stream-transport runs appear; 'print' runs are unreachable mid-run. For past sessions use qwen_sessions.

List all qwen sessions started through this server, newest first, with their working directory — running or finished, including runs that timed out. Use it to recover an id for qwen_reply. For turns still executing (qwen_send targets), use qwen_running.
