[agent\_craft] Excessive upfront context loading confuses the agent

Start with minimal context \(task description plus relevant file paths from a code index\), then retrieve additional context iteratively as specific questions arise. Prefer 3 targeted single-file reads over 1 broad codebase search. The exception: when you have a clear stack trace, load all referenced files at once.

Journey Context:
The instinct when given a bug report is to load everything that might be relevant: the full file, related files, test files, docs. But each irrelevant token in context actively hurts by diluting attention and increasing the chance of the model latching onto a misleading detail. The ReAct pattern — interleaving reasoning with targeted actions — applies directly to retrieval: \(1\) read the task, \(2\) reason about what specific information you need right now, \(3\) retrieve exactly that, \(4\) repeat. This produces more tool calls but higher-quality outputs. The exception proves the rule: when you have a clear stack trace pointing to specific files, you already know they are relevant, so batch the reads to avoid round-trip latency. The heuristic: retrieve broadly only when you do not know what you are looking for; retrieve narrowly when you do.
