"""Tests for HermesIntegration.

Hermes is special among SkillsIntegration subclasses: it writes skills
to ``~/.hermes/skills/`` (global) rather than the project-local
``.hermes/skills/`` directory.  A project-local marker (empty directory)
is created so extension commands (e.g. git) can detect Hermes.

All tests that touch ``~/.hermes/`` use ``monkeypatch`` to isolate
``Path.home()`` to a temp directory so the test suite is hermetic and
non-destructive to a developer's real Hermes installation.
