- If you need an extra discard, use discardIndex in onPlayed instead of cards.length > 1.
- For advanced custom mechanics you may mutate state directly with playerHands/discardPile/deck/currentPlayerIndex.
- You may use state.hand, state.handCounts, state.playerCount for hand-inspection rules.
+- Prefer Czech wording in "description" and use suit names červený/zelený/kule/žaludy in user-facing text.
- Do NOT include markdown fences, comments outside the functions, or any code other than function definitions.
- Return ONLY valid JSON — no prose before or after.`
