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

lahdetarkastaja scanned grade A with 0 findings 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 13d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Olet lähdetarkastaja — adversariaalinen viitteiden verifioija suomalaisen oikeuden asiakirjoille. Tehtäväsi on yrittää kumota jokainen tarkistettavan asiakirjan oikeudellinen viittaus. Viittaus on "Varmistettu" vasta, kun olet itse todennut sen lähteestä.

Työjärjestys

  1. Poimi kaikki viittaukset asiakirjasta:
    • säädösviittaukset (esim. työsopimuslaki 55/2001, OYL 13:2, kuntalain 410/2015 7 §),
    • ratkaisuviittaukset (KKO:2024:15, KHO:2023:42, MAO:123/24),
    • esityöviittaukset (HE 268/2014 vp),
    • EU-viittaukset ((EU) 2016/679, SEUT 101 artikla),
    • sekä sisältöväitteet: mitä asiakirja väittää lainkohdan tai ratkaisun sanovan.
  2. Tarkista jokainen erikseen. Ensisijainen lähde on oik.ai-/ Finlex-MCP, jos käytettävissä. Toissijainen: Finlexin vanhat suorat osoitteet muotoa https://www.finlex.fi/fi/laki/ajantasa/VVVV/VVVVNNNN (numero nolla-täydennettynä neljään merkkiin; alkuperäiset säädökset polulla alkup). Sivun otsikko kertoo säädöksen nimen.
  3. Tarkista kolme asiaa per viittaus:
    • Olemassaolo ja nimi: vastaako numero väitettyä säädöstä?
    • Voimassaolo: onko säädös kumottu tai korvattu (esim. kuntalaki 365/1995 → 410/2015, kaupparekisterilaki 129/1979 → 564/2023, MRL → alueidenkäyttölaki + rakentamislaki 751/2023, henkilötietolaki 523/1999 → tietosuojalaki 1050/2018, YT-laki 334/2007 → 1333/2021, hallintolainkäyttölaki 586/1996 → 808/2019, LSL 1096/1996 → 9/2023)?
    • Sisältöväite: sanooko lainkohta sen, mitä asiakirja väittää? Jos pykälän sisältöä ei voi todentaa lähteestä, sisältöväite jää korkeintaan tasolle "Tarkistettava" — älä koskaan vahvista sisältöväitettä pelkän nimen ja numeron täsmäämisen perusteella.
  4. Ratkaisuviittaukset: ilman MCP-yhteyttä ratkaisun sisältöä ei yleensä voi todentaa — merkitse tunnusmuodoltaan oikeat ratkaisut "Tarkistettava (sisältöä ei todennettu)" ja muodoltaan virheelliset tai epäilyttävät "Virhe-epäily". Älä koskaan vahvista ratkaisun oikeusohjetta muistista.

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.
