Scored across 3 tools
Each tool has a clearly distinct purpose: scan_component evaluates one component, diff_components compares two versions, and list_rules looks up detection rules. There is no meaningful overlap in action or output, and the descriptions explicitly clarify when to use each.
All tool names follow a consistent snake_case verb_noun pattern: scan_component, diff_components, list_rules. The verbs accurately reflect the operations and no mixed conventions are present.
Three tools is a focused and coherent surface for a security scanning server, with each tool earning its place. It is slightly thin, as additional operations like batch scanning or report retrieval might be expected, but nothing feels extraneous.
The surface covers the core lifecycle: scanning a component, comparing versions, and inspecting rules behind findings. Minor gaps exist, such as no batch scanning, scan history, or direct export of reports, but these are workaroundable and not central to the stated purpose.
