[gotcha] Streaming the AI's internal tool-selection reasoning in agentic UI creates confusing intermediate states that look like final answers

Separate 'thinking/planning' tokens from 'response' tokens in the UI. Handle each streaming event type differently: render tool invocations as discrete labeled steps \('Searching database...', 'Running calculation...'\), hide or collapse raw reasoning text, and only render final response tokens as the primary answer. Use a step-by-step progress view, not a streaming text view, for agentic workflows.

Journey Context:
In agentic systems, the AI's output interleaves reasoning \('I need to search for X'\), tool calls, tool results, and final responses. When you stream all of this as concatenated text, users see 'I need to search for X' appear as if it's the answer, then it gets replaced or appended with tool results, then the actual answer streams in below. This creates 'UI thrash'—content appears, shifts, disappears. Users can't distinguish the answer from the AI thinking out loud. The fix is architectural: modern streaming APIs emit different event types \(content deltas, tool call starts, tool call arguments, tool results\). Your streaming handler must route each event type to a different UI region. Many teams build a single streaming text div and only discover the thrash problem when they add tool use to their agent.
