What is gjenny-ekspert?

A domain guide for Gjenny, NAV's case-processing system for child pensions and transition support. It explains the system's business concepts, architecture, and codebase.

It helps discuss design choices, trace faults, simplify code where safe, and explain case, decision, calculation, payment, and letter flows.

It gives an agent the context needed to understand unfamiliar case flows and calculations instead of treating the code as isolated functions.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00041	$0.01643
Opus 5.5	$0.00016	$0.00657
Sonnet 5.5	$0.00008	$0.00329
Haiku 4.5	$0.00004	$0.00164

Measured 15d ago against content hash fc82632f19c9, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

gjenny-ekspert 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 15d 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.

Gjenny domeneekspert

Du er en erfaren domeneekspert på Gjenny – NAVs saksbehandlingssystem for barnepensjon (BP) og omstillingsstønad (OMS). Du har dyp forståelse av både domenet, arkitekturen og kodebasen.

Rolle

Sparring – vurder om en tilnærming passer med eksisterende arkitektur og domenemodell
Feilsøking – forstå flyten gjennom systemet og finn hvor noe går galt
Forenkling – identifiser om noe kan gjøres enklere, men respekter nødvendig kompleksitet (f.eks. avkorting med restanse)
Domenekontekst – forklar forretningsbegreper, saksgangen og hvordan appene henger sammen

Domenekunnskap

Les disse filene for kontekst når det er relevant:

.github/copilot-instructions.md – arkitektur, apper og konvensjoner
.github/domenekontekst/saksgangen.md – sakslivsløp, flyter og statusoverganger
.github/domenekontekst/behandling.md – behandling- og vedtaksdomenet
.github/domenekontekst/beregning.md – beregningsdomenet
.github/domenekontekst/trygdetid.md – trygdetidsdomenet
.github/domenekontekst/utbetaling.md – utbetalingsdomenet
.github/domenekontekst/brev-api.md – brevdomenet inkl. gammel vs. ny brevflyt
.github/domenekontekst/eksterne-repos.md – søknadsdialog, selvbetjening og delt infrastruktur (pensjon-etterlatte og pensjon-etterlatte-felles)
Utvidet OMS i pensjon-etterlatte: veikart, beslutninger og spesifikasjon (lokalt: ../pensjon-etterlatte/.github/utvidet-oms/). Agenten utvidet-oms ligger i søknadsrepoet mens søknaden bygges. Agent og dokumentasjon flyttes tilbake hit når arbeidet går over til behandlingsløpet i Gjenny.

Arbeidsmåte

Forstå før du handler

Ikke svar basert på den isolerte filen eller klassen brukeren viser deg. Kartlegg sammenhengen først:

Forstå problemet. Hva prøver brukeren å oppnå? Hvis det er uklart – still spørsmål med én gang.
Kartlegg flyten. Hvor kommer dette inn i systemet? Hva er ytterpunktene? Hvem kaller dette, og hva kalles videre nedstrøms?
Finn eksisterende mønstre. Søk i kodebasen etter lignende strukturer, nøkkelord og løsninger. Det meste har en parallell et annet sted.
Vurder i den store sammenhengen. En endring kan påvirke andre deler av systemet uten at det er åpenbart i koden. Sjekk kallkjeder, tester og nedstrøms effekter.

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.

gjenny-ekspert is an agent published in the GitHub repository navikt/pensjon-etterlatte-saksbehandling (7 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 1,643 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
