Report #98394

[agent\_craft] Loading entire codebases into context exhausts the token budget and drowns signal

Use a two-stage retriever: first a fast keyword or embedding index to select candidate files, then a token-aware reranker that picks the smallest subset fitting the remaining budget.

Journey Context:
Dumping the whole repo feels safe but destroys recall for the specific task because irrelevant files steal attention and tokens. Pure embedding retrieval is fast but imprecise. The right architecture is coarse retrieval followed by a second pass that scores candidates against the current goal and respects the budget. This mirrors production code-assistant pipelines and keeps latency acceptable.
