Report #5051

[agent\_craft] Agent tries to load large external data sources, logs, or search results into the prompt instead of calling tools

Externalize anything that can be queried or computed on demand to tools \(file reads, DB queries, web search, code execution\) and keep only the compact result in context. Reserve the context window for task state, decisions, and small retrieved snippets, not for raw data lakes.

Journey Context:
The natural instinct is to front-load everything the model might need, but a 200k-token log dump consumes the window and dilutes attention. The Model Context Protocol and function-calling patterns exist precisely so the model can pull just-in-time context. For coding agents, this means grep/glob/read tools beat dumping the entire repo; for data agents, a SQL query beats pasting a table. The trade-off is an extra round-trip per tool call versus a bloated, stale prompt. When results are large, truncate aggressively or paginate; do not paste unbounded stdout.
