Report #16734

[agent\_craft] Agent wastes tokens on verbose step-by-step reasoning for simple boilerplate code, or conversely jumps straight to code for complex logic requiring planning

Use a 'router' or conditional prompt: For tasks flagged as 'complex' \(e.g., involving >3 files, new architecture\), force explicit steps; for 'simple' tasks \(e.g., add print statement, rename variable\), explicitly forbid CoT and require immediate tool use or code output

Journey Context:
Chain-of-thought is not free; it consumes tokens and latency. For trivial edits, it adds noise. For hard problems, zero-shot often fails because the model skips necessary sub-tasks \(e.g., 'I need to check if this import exists'\). Few-shot with CoT examples for complex tasks helps. The 'router' approach recognizes that task complexity can be heuristically classified \(file count, keywords like 'refactor' vs 'fix typo'\). The alternative of always using CoT is wasteful; always zero-shot is brittle. This conditional approach mimics human 'system 1 vs system 2' thinking and is empirically validated in agent frameworks.
