Scored across 3 tools
Each tool serves a clearly distinct function: searching agents by skill, retrieving a detailed card, and calling an agent with payment. No overlap in purpose.
All tool names follow a consistent verb_noun pattern in snake_case (call_agent_with_payment, find_agents_by_skill, get_agent_card), making them predictable.
With 3 tools, the set is minimal but well-scoped for the server's purpose of discovery and basic interaction. Each tool earns its place, though a few more could be justified.
Core functionalities (search, details, call) are covered. Minor gaps exist, such as listing all agents without a skill filter or managing registrations, but agents can work around these.
