I don't understand why it was necessary to develop a new protocol for this. LSP already exists for discovering what relevant functions there are to call, wouldn't it be better to have a single source of truth for function docs rather than a markdown file which points the agent at the function so that it can then read more or less the same information from the function's docstring? This way you get a skills hierarchy which you have to maintain separately from whatever hierarchies exist for organizing your code. Is it really justified to maintain an entirely separate structure?
