Scored across 4 tools
Each tool targets a distinct phase in the safety workflow: pending-call gating, descriptor audit, single-function UX copy review, and address-level contract discovery. check_descriptor and explain_signature overlap somewhat since both operate on descriptors, but their scope is clearly separated by whole-descriptor structural review versus one-function copy review.
All four tool names follow a consistent snake_case verb_noun pattern: preflight_transaction, check_descriptor, explain_signature, and scan_contract. The verbs clearly reflect each tool's action, making the set predictable and easy to navigate.
Four tools is well-scoped for a specialized EVM clear-signing safety server. Each tool covers a distinct workflow stage without redundant peers, and none feels like filler.
The set covers the major lifecycle stages: pre-interaction contract discovery, descriptor authoring review, per-function copy review, and the pending-transaction gate. Runtime simulation and bytecode-level analysis are absent, but they are explicitly listed as out of scope, so the surface is mostly complete without dead ends.
