Report #98878

[agent\_craft] Agent hallucinates arithmetic, file listings, or multi-step transformations because it tried to do them in-context

Externalize deterministic computation to shell/python tools; reserve context for intent, constraints, and reasoning, not for data processing.

Journey Context:
LLMs are poor at precise arithmetic, exact file-system state, and large deterministic diffs. Keeping these in context invites hallucination and token bloat. The rule is: if a result has a verifiable ground truth \(git diff, dependency tree, test output, exact file content\), compute it with a tool and pipe only the concise result back. Context should hold the goal, the plan, and discovered facts. Tradeoff: tool calls add latency, but they slash error rates and free context for what the model is good at. This is the core insight behind ReAct loops.
