Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| get_best_design_modelA | Get the current #1 design model from designarena.ai's crowdsourced leaderboard, optionally filtered by category. Returns model info and OpenRouter availability. |
| get_leaderboardA | Browse the full designarena.ai design model rankings with optional category filter and pagination. Shows Elo ratings, win rates, and OpenRouter availability. |
| query_design_modelA | Send a design prompt to the best available model on OpenRouter, automatically selected from designarena.ai rankings. Skips models not available on OpenRouter. Requires OPENROUTER_API_KEY. |
| query_specific_modelA | Send a design prompt to a specific model via OpenRouter. Accepts either an OpenRouter model ID (e.g. 'anthropic/claude-sonnet-4-5-20250514') or a Design Arena model name (e.g. 'claude-sonnet-4-5'). Requires OPENROUTER_API_KEY. |

Scored across 4 tools
Each tool has a clearly distinct purpose: getting the top model, viewing the full leaderboard, querying the best available model, and querying a specific model. No overlaps.
All tool names follow a consistent verb_noun pattern in snake_case (get_best_design_model, get_leaderboard, query_design_model, query_specific_model), making them predictable.
With 4 tools, the server is well-scoped for its purpose of providing design model leaderboard information and querying capabilities via OpenRouter.
The tool set covers the core workflow (view leaderboard, query best/specific model) but lacks a tool to list all available models on OpenRouter, which is a minor gap.
