    A3.7/5.0

    Scored across 5 tools

    Disambiguation5/5

    Each tool has a clearly distinct purpose: two HTTP request methods (GET/POST) and three session management operations (list/create/destroy). No overlap or ambiguity; an agent can easily select the correct tool.

    Naming Consistency4/5

    All tools use snake_case with a consistent 'flare_' prefix, but the pattern is mixed: session tools include the resource noun 'session' (e.g., flare_session_create) while HTTP request tools omit it (e.g., flare_get). Minor deviation, still readable.

    Tool Count5/5

    Five tools is well-scoped for this domain: two core request methods and three session lifecycle operations. Each tool earns its place with no redundancy.

    Completeness5/5

    The surface covers the standard FlareSolverr API completely: GET/POST requests and session create/list/destroy. No obvious missing operations for the stated purpose.
