If you model starves because of small context window (your described symptoms), then I would suggest: a) Split the job between agents, each with it's own context window; b) Use advanced model as orchestrator for multiple coding/testing/reviewing agents; c) Use code indexers like https://github.com/ory/lumen or/and https://github.com/defendend/Claude-ast-index-search d) Use planning and detailed specifications preparation before the coding phase.
