Report #13117

[agent\_craft] Agent reads large files into context instead of executing code to extract specific data

Externalize data extraction to code execution. If the task requires finding a specific value, write and execute a script using grep, wc, or AST parsing to get the answer, rather than loading the entire file into the context window.

Journey Context:
Agents default to reading files because it is the most general tool. However, reading a 2000-line file consumes massive tokens and might miss the exact count. Code execution is deterministic, cheap, and uses zero context tokens for the intermediate data. The tradeoff is that writing a script takes an extra tool call and might fail, but it scales infinitely better than context stuffing.
