Designing effective tools for large language models (LLMs) is crucial for optimal performance, as poor tool design can lead to issues like bloat and confusion. Bloat occurs when tool definitions consume excessive context, degrading the LLM's reasoning abilities. Confusion arises from ambiguous naming, semantic similarity between tools, and unclear descriptions, leading to incorrect tool calls and retries. Practical approaches to mitigate these problems involve refining tool descriptions, optimizing response fields, providing clear error messages, and implementing schema constraints like enums and default values.
