Tool-Genesis (Code-Agent) - 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, a ReAct-style agent loop of up to 10 think-act-observe steps with sandboxed execution to run and repair the artifacts (Code-Agent), 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. Source: arxiv.org. Saturation forecast: Estimated already saturated. 14 models tracked.
