Report #56278

[agent\_craft] Agent loads entire large files into context to analyze them, consuming massive tokens and suffering from lost-in-the-middle effects

Delegate analysis to code execution. Write a script to process the file and return only the computed result, rather than reading the whole file into the LLM context.

Journey Context:
LLMs are bad at finding needles in large haystacks loaded into context. If you need to know 'how many times is X called?', reading a 2000-line file is expensive and error-prone. Writing a bash command \`grep -c 'X\(\)' file.py\` is 100% accurate and costs 10 tokens. Use the LLM for logic, use the execution environment for data processing.
