Report #81830
[agent\_craft] Agent reads entire large files at the start of a task to build context, wasting tokens before work begins
Start with a high-level map \(e.g., tree -L 2, README.md, or a repo map\). Then, use targeted reads \(e.g., grep, ripgrep, or line-range reads\) to drill down only into the specific modules relevant to the immediate sub-task.
Journey Context:
A common anti-pattern is the agent reading 10 files of 1000 lines each before writing a single line of code. This causes early context rot. The better approach is just-in-time context loading: read the interface or signature first, implement the change, and only read the implementation details if the interface is ambiguous. This keeps the context window focused on the active task.
