install.sh copies every skills-lock.json skill into .claude/skills while enable-plugins.js also enables the caveman and ponytail plugins that ship the same skills, so Claude listed 13 long descriptions twice on every turn of every session. enable-plugins.js now removes from the settings' .claude/skills every locked skill whose source is an enabled plugin's repository, taken from MARKETPLACES; .agents/skills keeps the copies for Codex and Gemini, which have no Claude plugin. The install message names it. test_dream checks that plugin copies go and other skills stay.
