Report #39580

[agent\_craft] Agent generates verbose, unstructured reasoning that consumes tokens without improving accuracy on simple coding tasks

Use 'Structured Zero-Shot CoT' instead of open-ended 'Let's think step by step'. Append a specific template to the prompt: 'Before writing code, outline your approach in 3 bullet points: 1\) Key algorithm/data structure, 2\) Potential edge cases, 3\) Time/space complexity target. Then write the code.' This constrains reasoning length and ensures relevant dimensions are considered without meandering.

Journey Context:
The original 'Zero-Shot CoT' paper used the phrase 'Let's think step by step', which unlocked reasoning capabilities but often leads to stream-of-consciousness text that repeats the problem statement and wastes tokens \(50-200 tokens per call\). For coding agents, we don't need philosophical reasoning; we need algorithmic clarity. By structuring the CoT into specific engineering dimensions \(algorithm, edge cases, complexity\), we get the benefits of deliberate planning \(reducing bugs\) without the cost of verbose text. This is a specific application of 'Tree of Thoughts' pruning to a single linear path. This pattern is observed in production systems which show a structured plan before execution and in advanced coding agents that use structured planning.
