Resource extension that synthesizes :eval and :docs generic actions for driving an LLM agent against a scoped Lua surface.

defmodule MyApp.Agents.MCPActions do
  use Ash.Resource, extensions: [AshLua.EvalActions]

  eval_actions do
    resource MyApp.Posts.Post, actions: [:read, :get_statistics]
    resource MyApp.Posts.Comment, actions: [:read]
  end
end

The synthesized actions inherit the caller's actor / tenant / context — both the script body and the documentation rendering are constrained to the configured (resource, action) pairs, and every Ash call inside the Lua script flows through the standard authorization machinery.
