[gotcha] Why streaming AI responses that pivot mid-stream feel worse than delayed refusals

Buffer the first 3-5 tokens before displaying to detect early refusals or direction changes. If a refusal is detected in the buffer, render it as a complete, considered response rather than a streaming walkback. For tool-use patterns, do not stream text until tool results are confirmed. Implement a 'commit threshold' — once streaming display begins, the response should not fundamentally change character.

Journey Context:
When you stream tokens in real-time, users start forming expectations about the complete response from the very first tokens. If the AI starts with 'Sure, here's...' and then pivots to 'Actually, I cannot help with that,' the pivot feels like a bait-and-switch. This is worse than a delayed refusal because the user already committed mentally to receiving an answer. The cognitive whiplash is real: the user's brain predicted a completion that did not arrive. This is especially painful with safety refusals that begin with acknowledgment \('I understand you want...'\) before the refusal — the user reads the first tokens as agreement, then gets rejected. The fix is to buffer a small window of tokens before starting to stream. This adds a tiny latency cost but prevents the worst pivots. For tool-use flows, this is even more critical — never stream text that might be invalidated by a tool result.
