Report #68285

[agent\_craft] Agent generates buggy code silently without reasoning through edge cases

Use explicit or tags for debugging/refactoring tasks \(>50 lines or >2 file changes\), but use direct generation for boilerplate \(<20 lines\) to optimize latency; never use CoT for simple CRUD.

Journey Context:
Chain-of-Thought \(CoT\) significantly improves accuracy on complex reasoning but increases token cost by 30-50% and latency. For coding, 'complex' means cross-file dependencies or algorithmic logic, not syntax generation. Common error is forcing CoT on simple 'create a React component' tasks, burning tokens on 'Let me think about the imports...' noise. Conversely, skipping CoT on 'refactor this authentication middleware' leads to missed edge cases \(rate limiting, token expiry\). The 50-line heuristic correlates with cognitive load; alternatives like 'always CoT' waste budget, 'never CoT' misses bugs.
