Scored across 1 tool
There is only one tool, so there is no possibility of selecting the wrong tool. Its purpose—finding external context a change reaches—is clearly stated and distinct.
The single tool uses a readable snake_case name with a server-specific prefix. With only one tool, there is no cross-tool pattern to violate, though the name is not a conventional verb_noun form.
A single tool is thin for a server, even a focused one. It does bundle multiple modes (impact, locate, pack), which helps, but the surface still feels minimal.
The tool covers impact analysis, fragment location, and code packing for a diff context, which is a coherent lifecycle for the stated purpose. Minor gaps may exist, such as explicit diff listing or file-level retrieval, but the core domain is addressed.
