Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00361 | $0.05019 |
| Opus 5 | $0.00180 | $0.02509 |
| Sonnet 5 | $0.00072 | $0.01004 |
| Haiku 4.5 | $0.00036 | $0.00502 |
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.
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)
- 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. - Internet — tylko do orzecznictwa TSUE (curia.europa.eu), doktryny i identyfikacji aktów. Po identyfikacji wróć do CELLAR po tekst.
- 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. - 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.
- 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). Uruchamiaj wyłącznie helper z bieżącego pakietu:
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

prawo-eu-eurlex is a skill published in the GitHub repository jamarpl21/prawo-pl-eli (15 stars, last pushed 17d ago), licensed MIT. It adds 361 tokens to every session and 5,019 once invoked, about $0.0018 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
