+name: usage
+description: >
+  Show Ollama Cloud credit/usage spent via the ollama.com usage API.
+  Triggers on: "/usage", "kolik kreditu", "kolik mam vycerpano",
+  "ollama usage", "spotreba ollama", "credits".
+---
+
+# Usage
+
+Zobrazí spotřebu kreditů na Ollama Cloud pro aktuální API klíč.
+
+## Spuštění
+
+```bash
+uv run skills/usage/scripts/ollama_usage.py
+```
+
+Skript čte `OLLAMA_API_KEY` z `workspace/.env` (vytvořeného uživatelem).
+Pokud chybí nebo klíč nefunguje (401/403), řekni to uživateli — nescrapuj web.
+
+## Výstup
+
+Text v češtině, stručně:
+
+- **Session**: použité $ + per-model requesty
+- **Weekly**: použité $ + per-model requesty
+- **Aktivita**: `activity.cost` za poslední 4 týdny
+
+Čísla vypisuj přesně jak je vrací API — žádné dopočítávání procent
+(API nezveřejňuje limit, takže % nelze spočítat ověřeně).
+
+## Poznámky
+
+- Endpoint: `GET https://ollama.com/api/usage`, hlavička
+  `Authorization: Bearer <key>` (ověřeno 2026-09, issue #15132 je zastaralá).
+- Klíč z `~/.ollama/id_ed25519` nefunguje — jen API key z ollama.com.
