Tool-Description Quality Is Not One Axis: A Regime Analysis of Where It Helps and Where It Backfires
Working paper (draft, not yet submitted)
Tool-description quality is widely treated as a broadly-applicable lever for agent tool-use, but it is not a single better/worse axis: the precision that helps an agent disambiguate within a family of confusable tools is orthogonal to, or actively harmful for, context-rich selection and for tool retrieval.
