The arena tools form a clear lifecycle set (create_agent, open_position, close_position, agent_profile, leaderboard) with distinct actions, and the utility tools (classify_text, url_to_markdown, validate_domain, validate_email) are separable. Minor overlap: validate_email performs an MX lookup that validate_domain also covers, and perp_risk_check could be confused with arena_open_position for pre-trade decisions.

Snake_case throughout with a consistent arena_ prefix grouping the trading tools and validate_* pairing the validators. url_to_markdown and perp_risk_check deviate slightly from a verb_noun shape but remain readable and predictable.

Ten tools is well-scoped: six arena lifecycle operations plus four independent paid utilities, each earning its place with no filler.

The arena covers create/open/close/inspect/leaderboard with equity and trade data, and the utilities cover common agent needs. Minor gaps: no way to list all agents owned by a caller, no agent update/delete or deposit/reset, and the two domains (paper trading plus generic validators) make full coverage hard to judge.
