ymparistovastuut

ymparistovastuut is a skill for Claude Code, Codex from akunikkola/claude-for-legal-finland. It costs 230 tokens per session (1,911 once invoked), scanned A, original, MIT.

A Finnish environmental-liability guide for contaminated soil and groundwater, environmental damage, environmental crimes, and environmental due diligence in transactions.

In plain words
What is it for?
It helps map responsibility for contamination, organise environmental due diligence, assess compensation and crime-related issues, and identify matters requiring technical investigation or legal review.
Why use it?
It helps separate public duties to clean up contamination, private compensation claims, and possible criminal liability. This gives transaction teams a clearer view of risks that may otherwise be missed.

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

ymparistovastuut 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 9d 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.

Ympäristövastuut — pilaantuminen, korvaukset ja transaktiot

Tämä skill jäsentää ympäristövastuiden kolme kerrosta — julkisoikeudellinen puhdistus-/ennallistamisvastuu, yksityisoikeudellinen korvausvastuu ja rikosvastuu — sekä niiden hallinnan transaktioissa. Perusteet: ../ymparistolupa-ja-valvonta/references/ymparisto-perusteet.md.

Vastuuvapaus: analyysit ovat tarkistettavia — ei oikeudellista neuvontaa. Pilaantuneisuuden toteaa tekninen tutkimus, ei tämä skill. Katso ymparisto-ja-kaavoitus/CLAUDE.md (mm. negatiivirajaus: pilaantumistiedon panttaamista kaupassa ei avusteta).

Tarkista laki lähteestä

Hae YSL:n (527/2014) pilaantuneen maaperän vastuusäännökset, ympäristövahinkolain (737/1994) korvausperusteet ja rikoslain ympäristörikossäännökset juristi:oikeustutkimus-skillillä. Toimivaltainen viranomainen PIMA-asioissa tarkistetaan lähteestä (LVV 2026 — ei ELY).

Kerros 1: Julkisoikeudellinen puhdistusvastuu (PIMA)

Jäsennä vastuuketju YSL:n mukaan (järjestys ja edellytykset lähteestä):

  1. Aiheuttaja — ensisijainen vastuu pilaantumisesta.
  2. Alueen haltija — toissijainen vastuu edellytyksin (tiesi tai olisi pitänyt tietää; kohtuullisuus).
  3. Kunta — viimesijainen.

Käytännön kysymykset: vanhat pilaantumiset ja sovellettava laki (siirtymäsäännökset — lähteestä), vastuun kohtuullistaminen, puhdistustarpeen arviointi ja PIMA-ilmoitusmenettely, kunnostuksen tavoitetasot. Maaperän ja pohjaveden pilaamiskiellot ovat ehdottomia — uusi pilaaminen ei ole "lupa-asia".

Kerros 2: Yksityisoikeudellinen korvausvastuu

  • Ympäristövahinkolaki (737/1994): ankara vastuu (ei edellytä tuottamusta) toiminnasta aiheutuneesta ympäristövahingosta; soveltamisala, sietämisvelvollisuus ja syy-yhteyden todennäköisyyskynnys lähteestä. Korvattavina mm. henkilö- ja esinevahinko, taloudellinen vahinko ja torjuntakustannukset.
  • Naapuruussuhteet: rasituksen kohtuuttomuus (immissiot — melu, pöly, haju) erillisenä perusteena; suhde lupaan (lupa ei poista korvausvastuuta — tarkista lähteestä).
  • Vakuutukset ja ympäristövahinkorahastojärjestelmä toissijaisena — tarkista voimassa oleva järjestelmä lähteestä.

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.
