Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

prawo-eu-eurlex scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/eurlex.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Prawo UE z oficjalnego repozytorium CELLAR/EUR-Lex

Skill do pracy z prawem Unii Europejskiej — przy każdym pytaniu o prawo UE oraz przy tworzeniu i analizie umów i pism, gdzie trzeba przywołać przepis unijny, zweryfikować podstawę prawną lub datę stosowania. Cytowanie przepisów UE z pamięci albo z portali jest zawodne (nowelizacje, sprostowania, różne daty stosowania) — ten skill sięga do źródła pierwotnego: CELLAR, wspólnego repozytorium Urzędu Publikacji UE, które zasila EUR-Lex (SPARQL + REST, bez rejestracji i klucza).

Kolejność źródeł (przepis ≠ internet)

  1. Treść przepisu UE — wyłącznie z EUR-Lex/CELLAR. Nigdy nie cytuj brzmienia z pamięci ani z portali. Jeśli wynik wyszukiwania internetowego podał brzmienie — zweryfikuj przez eurlex.py, zanim go użyjesz w odpowiedzi.
  2. Internet — tylko do orzecznictwa TSUE (curia.europa.eu), doktryny i identyfikacji aktów. Po identyfikacji wróć do CELLAR po tekst.
  3. Pytanie bez wskazanego przepisu („czy to zgodne z prawem UE…", „czy RODO pozwala…") to też zadanie dla tego skilla — najpierw ustal akt (tabela niżej lub szukaj), pobierz przepisy (tekst --fragment), dopiero potem ewentualnie internet po orzecznictwo.
  4. Granica PL/UE: rozporządzenie UE stosuje się wprost; dyrektywa działa przez TRANSPOZYCJĘ — polską ustawę wdrażającą sprawdzaj skillem prawo-pl-eli (ELI Sejmu). Przy pytaniach mieszanych (np. RODO + polska ustawa o ochronie danych) używaj OBU skilli.
  5. Delegując research subagentowi, wpisz do jego promptu: „treść przepisów UE pobieraj wyłącznie przez scripts/eurlex.py (skill prawo-eu-eurlex); internet tylko do orzecznictwa i doktryny".

Narzędzie

Wszystko robi helper scripts/eurlex.py (tylko biblioteka standardowa Pythona — bez instalacji, bez klucza API). Skrypt leży obok tego pliku SKILL.md — NIE zakładaj, że to ~/.claude/skills/ (skill zainstalowany jako plugin leży w katalogu pluginów; w Claude Code: ${CLAUDE_PLUGIN_ROOT}/skills/prawo-eu-eurlex).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
