[agent\_craft] Agent hallucinates imports or class structures when reading code snippets via RAG instead of full files

For coding tasks, prefer reading entire files over chunk-based RAG retrieval. Use RAG only to identify which files to read, not to provide the code context itself.

Journey Context:
Standard RAG chunks code into 500-token pieces. When an agent retrieves a chunk of a Python class, it loses visibility of the class imports, parent classes, and sibling methods. The agent then hallucinates methods or imports that don't exist. Reading the whole file costs more tokens upfront but drastically reduces the loop iterations required to fix compilation/syntax errors caused by missing structural context. Aider's whole file approach vs. chunked RAG is a classic example of this tradeoff.
