Report #93145

[agent\_craft] Agent wastes tokens on unnecessary reasoning for simple code generation, or conversely, generates buggy code without thinking through edge cases

Use explicit or reasoning steps ONLY when the task involves debugging, error analysis, complex logic, or ambiguous requirements. For straightforward code generation \(boilerplate, simple functions\), disable CoT to reduce latency and prevent hallucination of non-existent requirements.

Journey Context:
The default assumption is 'more reasoning is better,' but this is wrong for coding agents. When generating a standard REST endpoint or DTO class, forcing the model to 'think step by step' invites it to invent constraints \(e.g., 'I should add validation for X'\) that weren't in the requirements, leading to over-engineering. Conversely, when debugging a stack trace or analyzing a race condition, CoT is essential to narrow down hypotheses. The rule of thumb: if the input is an error message or a complex spec, enable CoT; if it's a 'generate X' request, use zero-shot. Anthropic's research on 'extended thinking' modes and OpenAI's o1 model guidance suggest separating 'reasoning' tasks from 'generation' tasks explicitly.
