disambiguation

Tools with overlapping purposes cause misselection. A server with great individual descriptions but overlapping tools scores low here. Invocation cost plays no part in this number: shadowing risk is reported beside the score, not inside it.

5

every tool has a clearly distinct purpose, no ambiguity

4

mostly distinct, one or two could be confused

3

some overlap exists but descriptions help

2

multiple tools have unclear boundaries

1

several tools appear to do the same thing

• Make purposes disjoint and say so in both descriptions, or collapse overlapping tools into one.
• A boundary is describable ("to filter by user, use search_calls_extensive"); a priority ("always call this first") is not, and is the sign of a tool-set problem.
