Report #7213

[agent\_craft] Agent loads entire 2000-line files into context to answer a question about a single function signature

Default to line-range reads or symbol-extraction tools. Only load the full file when the task is a major refactor requiring cross-cutting understanding of the whole file's logic.

Journey Context:
Naive agents use cat or read on whole files because it is easy. This quickly fills the context window with boilerplate, imports, and unrelated logic, diluting the attention on the actual target and increasing cost. Targeted reads require the agent to first locate the symbol \(e.g., via grep or AST\), adding a step, but the resulting context is highly compressed and high-signal, preserving window space for complex reasoning.
