Report #97372

[agent\_craft] Agent tries to reason over data that should be computed externally

Use tools for deterministic, large, or verifiable operations and load only compact results or semantic interpretations into context. If a task can be grep, pytest, or a SQL query, run it externally; do not ask the model to hold the raw data in working memory.

Journey Context:
Loading logs, schemas, or intermediate calculations into context burns tokens and invites hallucination. The right boundary is: context is for meaning and decisions, tools are for ground truth. Anthropic's coding agent workflow relies on tool results as environmental feedback rather than context material.
