nav-architecture-review

nav-architecture-review is a skill for Claude Code, Codex from navikt/copilot. It costs 23 tokens per session (2,226 once invoked), scanned A, original, MIT.

An architecture decision record (ADR) generator with reviews from architecture, security, and platform viewpoints. An ADR is a written explanation of an important technical choice and its alternatives.

In plain words
What is it for?
Use it to describe a proposed change, compare at least two options, select a solution, and list the work needed to implement it. It is tailored to Nav's architecture review process.
Why use it?
It gives teams a shared record of why a change was chosen and what risks it introduces. The separate viewpoints help reveal concerns that one reviewer might miss.

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

nav-architecture-review 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.

Architecture Review — ADR Generator

Generer et Architecture Decision Record (ADR) med review fra tre perspektiver: arkitektur, sikkerhet og plattform. Følger Navs Architecture Advice Process.

Workflow

  1. Forstå konteksten — hva er endringen og hvorfor?
  2. Evaluer fra tre perspektiver — arkitektur, sikkerhet, plattform
  3. Identifiser alternativer — minst to alternativer + valgt løsning
  4. Generer ADR — formelt dokument med Nav-spesifikke vurderinger
  5. Liste aksjonspunkter — hva må gjøres for å realisere beslutningen

Steg 1: Kontekst

Still disse spørsmålene:

  • Hva er endringen? (én setning)
  • Hvorfor gjøres den? (forretningsbehov, teknisk gjeld, regulatorisk)
  • Hva er konsekvensen av å ikke gjøre noe?
  • Hvilke team påvirkes?

Steg 2: Fler-perspektiv-review

Evaluer fra tre perspektiver. For hvert perspektiv: identifiser bekymringer, risiko og anbefalinger.

Perspektiv 1: Arkitektur

  • Passer dette i Navs overordnede arkitektur?
  • Finnes det enklere alternativer?
  • Introduserer det unødvendig kompleksitet?
  • Er det i tråd med team-autonomi-prinsippet?
  • Gjenbruker det eksisterende plattform-kapabiliteter?
  • Navs prinsipper: Team First, essential complexity, Product Development

Perspektiv 2: Sikkerhet

Dypere sikkerhetsgjennomgang: For trusselmodellering, OWASP-sjekklister og compliance-vurderinger, delegér til @security-champion-agent som har komplett sikkerhetsmateriale.

  • Hvilke data behandles? Klassifiseringsnivå?
  • Er autentisering og autorisasjon riktig?
  • Er tilgangsstyring minimalt nødvendig (least privilege)?
  • Er PII beskyttet (logging, lagring, transit)?
  • Følger dette Navs Golden Path for sikkerhet?

Perspektiv 3: Plattform

  • Fungerer dette på Nais (Kubernetes/GCP)?
  • Er ressurskrav realistiske?
  • Er observerbarhet ivaretatt?
  • Er CI/CD-pipeline enkel og vedlikeholdbar?
  • Er det avhengigheter til on-prem eller legacy?

Perspektiv 4: Migrasjon (kun ved endring av eksisterende system)

  • Er endringen bakoverkompatibel? Kan gammel kode kjøre med nytt skjema?
  • Finnes det en rollback-plan som ikke medfører datatap?
  • Er det definert exit criteria for når migreringen er ferdig?
  • Er feature toggle satt opp for gradvis utrulling?
  • Er berørte konsumenter (andre team/tjenester) identifisert og informert?
  • Er det satt opp rekonsiliering for å verifisere datakonsistens?
  • Er dekommisjoneringsplan for gammel løsning definert?
  • Er migrasjons-observerbarhet på plass (gammel vs ny path, avviksteller)?

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.

nav-architecture-review is a skill published in the GitHub repository navikt/copilot (54 stars, last pushed yesterday), licensed MIT. It adds 23 tokens to every session and 2,226 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
