Code Mode API and LSP

[ryanpeach]

Enhancement

I think that LLM's will have trouble, even with schema, writing code calls like this:

await call_tool("foo", {"bar": "baz"})

What we need is to have a resource, given a list of tool names, a python API, like so:

@dataclass
class FooParams:
    bar: str

@dataclass
class FooReturns:
    baz: str

async def foo(params: FooParams) -> FooReturns:
    return FooReturns(**(await call_tool("foo", asdict(params))))

The LLM can retrieve this from a resource or a prompt with a parameter taking a list of tool names.

The code executor can have this preprended to the top of any code its executing.

Then we can run an LSP on the code before we even pass it to the execution environment and return detailed syntax errors too.

Hope this isn't a duplicate.
