+### OnTransformAst
+This function provides the ability to modify `ast`.
+
+After the token is generated and before the comments are compiled, so it is possible to modify ast directly and ensure that changes to the comments take effect as well.
+
+You can return new one `ast` or modify the origin `ast`.
+
+```Lua
+---@param  uri  string # The uri of file
+---@param  ast  parser.object # The file ast
+---@return parser.object? ast
+function OnTransformAst(uri, ast) end
+```
+
+### VM.OnCompileFunctionParam
+This function modifies the behavior of a function when compiling (presumably) the type of its arguments.
+
+`next` is the compiler's default behavior for functions. `func` is the function to be compiled, `param` is the parameter.
+If all functions return `false`, the parameter is defined as `any`.
+
+```Lua
+---@param next  fun(func:parser.object, param:parser.object) # Default behavior
+---@param func  parser.object                                # The function
+---@param param parser.object                                # The param
+---@return boolean? ready                                    # Already know the type.
+function VM.OnCompileFunctionParam(next, func, param) end
