[agent\_craft] Writing computations, transformations, or exact diffs inside the LLM prompt instead of running code

Externalize exact work to deterministic code execution: shell commands, file I/O, parsing, diffing, and arithmetic belong in tools. Keep in context only the decision logic and the human-readable results the tool returns.

Journey Context:
It is tempting to ask the model to 'mentally' parse JSON, count tokens, or generate a patch. That burns context, introduces hallucination, and wastes capacity. The correct split is: model decides intent and handles ambiguity; code handles structure and exactness. Tool-calling APIs are designed for exactly this boundary. The risk of tool use is latency and sandboxing, but the gain in correctness and context efficiency dominates.
