[agent\_craft] Chain-of-Thought increasing syntax errors in simple code generation

Disable CoT \(remove 'Let's think step by step'\) for boilerplate/syntactic transformations; enable CoT only for complex algorithmic logic requiring edge-case analysis

Journey Context:
While Chain-of-Thought \(CoT\) prompting improves performance on complex reasoning tasks \(math, logic\), it paradoxically degrades code generation for simple, boilerplate tasks \(getters/setters, simple refactors\). Forcing the model to 'think step by step' before generating simple syntax causes it to over-analyze, introducing typos and 'creative' edge-case handling that breaks the code. Research shows CoT increases syntax error rates on simple functions while reducing logic errors on complex algorithms. The heuristic: use zero-shot direct generation for syntactic transformations \(moving code, renaming\) and reserve CoT for algorithms with complex control flow or edge cases.
