Report #36151

[frontier] Agent latency stalling on expensive context preparation \(retrieval, summarization\) that could be predicted and pre-computed

Implement speculative context preparation: run lightweight 'shadow' agent threads that predict likely next user intents based on current trajectory, pre-compute expensive context \(retrieval, tool calls, summarization\) for the top-2 predicted branches, and cache in hot memory. When actual next step is revealed, merge pre-computed context if matched, or discard if diverged.

Journey Context:
This adapts 'speculative execution' from CPU architecture to agent systems. Early 2025 implementations recognize that user turns in multi-step tasks are highly predictable \(Markovian\), and the cost of wasted speculative computation is lower than the latency of on-demand retrieval. The pattern requires a 'speculation controller' that monitors prediction confidence and throttles speculation when uncertainty is high. Tradeoff: increases token consumption \(speculative waste\) but reduces user-perceived latency by 40-60%. This is emerging as critical for real-time voice agents and coding assistants where latency > accuracy for immediate feedback loops, and compute is cheaper than user time.
