[agent\_craft] Agent loads entire files or codebase into context upfront — wastes window on irrelevant code

Load context progressively: start with skeletal structure \(directory tree, type signatures, exported APIs\), then drill into specific files or functions only when the agent's reasoning demands it. Implement as a 'lazy context' pattern where the agent has a 'list structure' tool and a 'read detail' tool, and must call them sequentially.

Journey Context:
The naive approach is to load as much context as possible upfront to 'give the model everything it needs.' This fails for three reasons: \(1\) it wastes the context window on code the agent will never reference, \(2\) it makes relevant signal harder to find \(needle in a haystack\), \(3\) it often hits token limits before the real work begins. Progressive loading mirrors how experienced developers navigate unfamiliar code — you read the directory structure, then the module headers, then drill into the specific function. The overhead of extra retrieval steps is paid back by higher-quality reasoning on focused context. Agents with progressive loading make fewer 'hallucinated API' errors because they're working from actual code, not from a fog of partially-relevant context.
