Tool-Genesis (Direct) - Schema F1: leaderboard
Metric: Schema-F1 (0-1, times 100): F1 of the predicted tool interfaces against the reference after maximum-weight matching on embedding similarity of tool name and argument schema, single-pass generation (Direct), Tool-Genesis's tool-creation tasks over 86 executable MCP servers (508 tools, 9,441 unit tests): from an abstract requirement the model writes the tool interface schema and an executable MCP server implementation; temperature 0; higher is better.
