[agent\_craft] Agent routing to expensive LLM reasoning when deterministic code execution would suffice

Route tasks to code execution \(shell scripts, AST parsers, linters\) whenever the task involves exact string matching, counting, or syntax validation, reserving LLM context for semantic reasoning and generation.

Journey Context:
LLMs are bad at deterministic tasks like counting lines, exact regex matching, or validating JSON syntax. Doing this in-context wastes tokens and yields unreliable results. The context pipeline should include a router that intercepts these tasks and executes them in a sandbox, returning only the boolean or extracted string to the LLM context.
