Report #14027

[agent\_craft] Excessive latency and token cost for simple, deterministic code edits \(e.g., renaming a variable\) because the model generates lengthy reasoning before acting

Disable chain-of-thought for deterministic, low-uncertainty tasks. Use direct tool calling with a terse system prompt: 'Analyze the request and immediately output the tool call. No explanation needed.' Reserve CoT for debugging, ambiguous requirements, or multi-step planning.

Journey Context:
CoT is a tax on every interaction. For 'rename foo to bar', the model does not need to 'think step by step'—it just needs to emit the edit. Premature optimization of reasoning wastes tokens and increases API costs. The heuristic: if the task has <2 decision points and clear success criteria, use direct mode. If the agent needs to search, compare, or debug, enable CoT. This is the speed/accuracy tradeoff in agent design.
