Skill packs install to ~/.claude/skills/<slug>/— Claude Code's standard skills directory. They are auto-discovered on next startup.
After installing a skill pack for the first time, restart Claude Code (or VS Code) so it picks up the new ~/.claude/skills/ directory. Subsequent installs and updates do not require a restart.
Files land at ~/.claude/skills/<slug>/ (user scope, the default) or .claude/skills/<slug>/ (project scope, when you pass --scope project). Claude Code discovers SKILL.md from any subdirectory under its skills root.
Only files tracked by MemoryMarket are removed. Files you created inside the skill directory are preserved.
