Report #4539

[agent\_craft] Agent loads entire large files into context to search for a specific function or bug

Delegate search to deterministic code execution tools \(e.g., ripgrep, ast-grep, or IDE language servers\) instead of reading the whole file. Only load the specific matched lines or AST nodes into the context window.

Journey Context:
Reading a 2000-line file wastes context tokens and increases hallucination risk. Tools like grep or git diff are deterministic and free from token limits. The agent's context window is a scarce resource reserved for reasoning, not for holding data that a Unix tool can process faster and more accurately.
