Reasoning now flows as its own stream — symmetric to the answer's ``delta`` / ``stream_end`` pair — instead of being shipped as one oversized progress message. This lets WebUI render a live "Thinking…" bubble that updates in place, then auto-collapses when the stream closes. Other channels remain plugin no-ops by default. ## Protocol New metadata: ``_reasoning_delta`` (chunk) and ``_reasoning_end`` (close marker). ChannelManager routes both to the dedicated plugin hooks below; the legacy one-shot ``_reasoning`` is kept for back-compat and BaseChannel expands it into a single delta + end pair so plugins only ever implement the streaming primitives. WebSocket emits two new events: - ``reasoning_delta`` (event, chat_id, text, optional stream_id) - ``reasoning_end`` (event, chat_id, optional stream_id) ## BaseChannel surface - ``send_reasoning_delta(chat_id, delta, metadata)`` — no-op default - ``send_reasoning_end(chat_id, metadata)`` — no-op default - ``send_reasoning(msg)`` — back-compat wrapper, base impl forwards to the streaming primitives A channel adds reasoning support by overriding the two streaming primitives. Telegram / Slack / Discord / Feishu / WeChat / Matrix keep the base no-ops until their bubble UIs are adapted; reasoning silently drops at dispatch, never as a stray text message. ## AgentHook Adds ``emit_reasoning_end`` to the hook lifecycle. ``_LoopHook`` tracks whether a reasoning segment is open and closes it on: - the first answer delta arriving (so the UI locks the bubble before the answer renders below), - ``on_stream_end``, - one-shot ``reasoning_content`` / ``thinking_blocks`` after a single non-streaming response. ## WebUI - ``UIMessage.reasoning`` is now a single accumulated string with a companion ``reasoningStreaming`` flag. - ``useNanobotStream`` consumes ``reasoning_delta`` / ``reasoning_end``; legacy ``kind: "reasoning"`` is auto-translated to a delta + end. - New ``ReasoningBubble``: shimmer header + auto-expanded while streaming, collapses to a clickable "Thinking" pill once closed, respects ``prefers-reduced-motion``. - Answer deltas adopt the reasoning placeholder so the bubble and the answer share one assistant row. ## Tests - ``tests/channels/test_channel_manager_reasoning.py`` — manager routes delta + end, drops on channel opt-out, expands one-shot back-compat. - ``tests/channels/test_websocket_channel.py`` — new ``reasoning_delta`` / ``reasoning_end`` frames, empty-chunk safety, no-subscriber safety, back-compat expansion. - ``tests/agent/test_runner_reasoning.py`` — runner closes the segment on streaming answer start and after one-shot reasoning. - WebUI ``useNanobotStream`` + ``message-bubble`` cover the new protocol and the shimmer styling. ## Docs ``docs/configuration.md`` and ``docs/websocket.md`` document the new events and the plugin contract.
