"""
Test for the Claude Code plugin manifest (Issue #1350).

Claude Code's plugin schema requires "agents" to be an array of .md file
paths (a bare directory string is rejected with "agents: Invalid input"),
while "skills" may be a directory string. This guards the manifest shape
so the bundled plugin stays installable.
