In-memory storage provider backed by an Agent process.

Designed for testing. State is a flat map where paths are keys and values are {:file, binary()} or :dir. Directories are inferred from file paths (a put to "a/b/file.txt" makes dir?("a/b") return true) and can also be created explicitly via ensure_dir/1.

Test Setup

Use start_supervised!/1 in each test for automatic isolation — the Agent dies with the test process, so no cleanup is needed:

setup do
  start_supervised!(SkillKit.Storage.Memory)
  :ok
end

Configure as the test provider:

# config/test.exs
config :skill_kit, SkillKit.Storage,
  provider: SkillKit.Storage.Memory

Seeding Test Data

setup do
  start_supervised!(SkillKit.Storage.Memory)
  Storage.ensure_dir!("kits/greeting/skills/hello")
  Storage.put!("kits/greeting/skills/hello/SKILL.md", skill_content)
  {:ok, dir: "kits/greeting"}
end

How list/1 Works

list/1 returns direct children only (matching File.ls semantics). Given state %{"a/b/c.txt" => {:file, ...}, "a/b/d/e.txt" => {:file, ...}}, list("a/b") returns {:ok, ["c.txt", "d"]}.
