Report #71558

[agent\_craft] Agent uses LLM reasoning to calculate file tree structures, count lines, or perform string matching, wasting tokens and hallucinating results

Never use the LLM to compute what a shell command or script can. Externalize filesystem traversal, line counting, and exact string matching to bash or python execution. Only bring the deterministic results into context.

Journey Context:
LLMs are fundamentally bad at spatial reasoning and exact counting. Asking an agent to 'list all python files' in a large repo forces it to guess or use slow, token-expensive tools. A quick shell command is deterministic, near-zero token cost, and exact. Context window space is too expensive for deterministic operations.
