defmodule Skills.Toml do
@moduledoc """
Encode a skill definition as TOML.
Skills are stored as TOML files so they are easy to create and edit by hand.
This module intentionally implements only the subset of TOML we need for the
skill schema:
- strings
- string arrays
- a shallow `response_format` table (string/number/bool values)
If we need richer encoding later, we can expand this module or swap it for a
dedicated encoder.

Encode a `%Skills.Skill{}` to a TOML string.
The output is stable (fixed key order) to minimize noisy diffs.
