Tool-Schema Compression Enables Agentic RAG Under Constrained Context Budgets
The paper discusses the challenges faced by agentic RAG systems due to tool schemas consuming context windows needed for retrieval-augmented generation. It presents a systematic study evaluating various models and the impact of tool-schema compression on performance. The findings indicate that compressed schemas significantly improve functionality in constrained contexts, establishing their necessity for effective deployments.
- ▪Agentic RAG systems struggle with resource conflicts as tool schemas occupy the same context window required for generation.
- ▪The study evaluates 14 models and shows that applying tool-schema compression can restore functionality in limited context budgets.
- ▪Compressed schemas lead to a significant increase in exact-match performance, particularly in scenarios where tool definitions overflow the context window.
