Report #38741

[agent\_craft] Agent wastes tokens on elaborate reasoning chains for straightforward CRUD operations, causing context window exhaustion

Use explicit routing: prepend a classification step that tags the task complexity \(SIMPLE vs COMPLEX\). For SIMPLE tasks \(single table queries, basic file reads\), disable CoT and use direct answer format; reserve CoT only for COMPLEX tasks requiring multi-step logic or debugging

Journey Context:
CoT is overapplied. Agents default to 'thinking step by step' for everything, burning 30-40% of context window on trivial operations. The insight is that not all tasks need reasoning; some just need mapping. The classification router pattern \(used by LangChain's 'route chains'\) prevents this waste. Tradeoff: adds ~100ms latency for the classification call, but saves significant token costs and prevents context overflow in long sessions.
