Scored across 1 tool
There is only one tool, so there is nothing to confuse it with. Its name and description clearly scope it to diff-impact analysis with three explicit modes.
A single tool with a consistent namespaced verb_noun-style name (diffctx_context) has no competing conventions to clash with. Naming is clean and predictable for the server's prefix.
A one-tool surface is thin for a context/analysis server; folding impact, locate, and pack into a single mode-switched tool reduces discoverability of those capabilities. It is focused but borderline minimal.
As a read-only change-impact analysis tool it covers the core need (callers, tests, contracts, fragment ids, code packing) with sensible diff_ref/symbol inputs. Gaps exist around targeting by file/line or explicit contract lookup, but the main workflow is covered.
