Yes — Claude Code skills are isolated by filename, so installing both is safe. They only conflict if they share the same trigger phrase, which is rare. Read each SKILL.md before installing to confirm the trigger patterns don't collide.

Are these skills free?

Yes — every skill listed on ClaudSkills is free to install. The catalog itself is published under CC BY 4.0; per-skill SKILL.md license is set by the original author. Check each skill page's Attribution section for the upstream license.

1. GAME.md / roster   → /unikit-gd-spec      (content edits, and add-system for any new system a later delta needs)
2. systems            → /unikit-gd-system     (the single upstream source — always before content/flow)
3. content types      → /unikit-gd-content    (a sink of the system axis)
4. flows              → /unikit-gd-flow        (a sink of the system axis)
