Create a new tool in the Tool Registry with an initial version. The tool definition should be in OpenAI function-calling format. Tool names must be unique within a workspace. The initial version is created with version number 1. Pass an optional execution payload to attach a sandbox-executable body. PromptLayer will run it between LLM turns whenever a prompt references the tool. See Auto Tool Execution for the body model and conventions.
