DESCRIPTION

Generates an agent tool card from a tool name + plain-English description (and optional parameter hints): a strict OpenAI/A2A-compatible spec of { name, description, parameters: <JSON Schema> }. Powered by Venice zai-org-glm-4.7 in json_object mode. Useful for retrofitting LLM-callable tool descriptions onto existing API endpoints. Use it as an OpenAI function-calling spec generator, A2A tool-card builder, or agent tool description writer.
