[agent\_craft] Agent wastes tokens on step-by-step reasoning for trivial syntax errors or fails to reason through complex logic bugs

Implement a routing heuristic: if the error is a SyntaxError, ParseError, or TypeError with a clear stack trace, skip chain-of-thought and proceed directly to fix generation; if the error is a logic bug, silent failure, or integration issue, force CoT before proposing a fix.

Journey Context:
CoT is expensive \(tokens and latency\) and can hallucinate reasoning steps when the actual fix is a trivial character change \(e.g., missing colon\). However, for logic errors, jumping straight to a fix often results in surface-level patches that don't address root causes. The routing heuristic must be accurate; using error type and stack trace depth is a reliable proxy. The alternative—always using CoT—burns budget, and the alternative—never using it—misses deep bugs. This conditional approach optimizes the accuracy/cost frontier.
