arvopaperimarkkinat

arvopaperimarkkinat is a skill for Claude Code, Codex from akunikkola/claude-for-legal-finland. It costs 252 tokens per session (1,722 once invoked), scanned A, original, MIT.

A reference guide to Finnish and EU rules for companies whose shares are traded on a stock exchange, including disclosure duties and insider trading controls.

In plain words
What is it for?
Use it to prepare or check work involving stock-exchange announcements, unpublished price-sensitive information, insider lists, trading restrictions and related transactions.
Why use it?
It helps organise which rules apply when a listed company must publish information, delay an announcement, manage insider lists or restrict trading. Drafts still need legal review and are not legal or investment advice.

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

arvopaperimarkkinat 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 12d 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.

Arvopaperimarkkinat — tiedonanto, sisäpiiri ja transaktiot

Tämä skill jäsentää listayhtiön ja sen neuvonantajien arvopaperimarkkinaoikeudelliset velvoitteet. Sääntelypohja: arvopaperimarkkinalaki (746/2012) + suoraan sovellettava EU-sääntely (MAR, esiteasetus) + Fivan määräykset ja Nasdaq Helsingin säännöt. Perusteet: ../rahoitus-ja-vakuudet/references/rahoitus-perusteet.md.

Vastuuvapaus: luonnokset ovat tarkistettavia — ei oikeudellista neuvontaa eikä sijoitusneuvontaa. Sisäpiiritiedon väärinkäyttöä ei avusteta — ehdoton negatiivirajaus (CLAUDE.md). Seuraamukset ovat ankaria: hallinnolliset seuraamusmaksut ja rikosvastuu.

Tarkista sääntelykerrokset lähteestä

Kolme kerrosta, tarkista kaikki: AML 746/2012 (Finlex), EU-asetukset (MAR, esiteasetus — EUR-Lex, ml. ESMA:n ohjeet) ja Fivan määräykset ja ohjeet sekä pörssin säännöt [tarkista]. Käytä juristi:oikeustutkimus-skilliä kansalliseen lakiin; EU-tekstit ja kynnysarvot lähteestä.

Sisäpiiritiedon hallinta (MAR)

  1. Onko tieto sisäpiiritietoa? Täsmällistä, julkistamatonta, olennaisesti hintaan vaikuttavaa — arvio dokumentoidaan jokaisessa hankkeessa (järkevän sijoittajan testi). Epävarmassa tilanteessa käsittele sisäpiiritietona.
  2. Julkistaminen mahdollisimman pian — pääsääntö; pörssitiedotteen sisältövaatimukset (olennaisuus, johdonmukaisuus aiempaan viestintään).
  3. Lykkääminen — edellytykset (oikeutettu etu, ei harhaanjohtavuutta, luottamuksellisuus turvattu) ja menettely (lykkäyspäätöksen dokumentointi, ilmoitus Fivalle julkistettaessa) — yksityiskohdat lähteestä.
  4. Sisäpiiriluettelot — hankekohtaiset; ajantasaisuus, tietoisuusvahvistukset; pysyvät sisäpiiriläiset eri asia.
  5. Tiedon vuotaminen → välitön julkistaminen; huhujen kommentointipolitiikka valmiiksi.

Johdon liiketoimet ja kaupankäyntirajoitukset

  • Johtohenkilöiden ja lähipiirin liiketoimi-ilmoitukset (määräajat ja kynnys lähteestä) yhtiölle ja Fivalle + julkistaminen.
  • Suljettu ikkuna ennen tulosjulkistuksia (pituus lähteestä) — yhtiön sisäinen kaupankäyntiohje usein laajempi; laadi ohjeluonnos.

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.
