Description

AI SDK currently supports json based tools well, but does not provide a first class way to define OpenAI custom/freeform
tools (type: "custom").

Please add support for passing OpenAI custom tools through AI SDK, including:

• type: "custom"
• name, description
• optional format:
  • { type: "grammar", syntax: "lark" | "regex", definition: string }

This is needed for tools like freeform patching/editing where JSON schemas are too restrictive.
