- LOWTool 'execute-code' doesn't follow camelCase/snake_casein execute-code
- LOWTool 'execute-command' doesn't follow camelCase/snake_casein execute-command
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.
