Ragex.MCP.Formattable protocol (Ragex v0.18.0)

Protocol for compacting MCP tool responses.

Types that implement this protocol define how to produce a compact representation (signatures, locations, counts only) versus a verbose one (full detail -- the current default behavior).

The formatter calls compact/2 when verbose: false (the new default) and falls through to the raw value when verbose: true.

Implementing for a new struct

defimpl Ragex.MCP.Formattable, for: MyResult do
  def compact(result, opts) do
    %{summary: result.summary, count: result.count}
  end
end
