Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00026 | $0.03362 |
| Opus 5 | $0.00013 | $0.01681 |
| Sonnet 5 | $0.00005 | $0.00672 |
| Haiku 4.5 | $0.00003 | $0.00336 |
Grade A, and why
nav-plan 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 11d 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.

Nav Architecture Plan
Gå fra en vag idé til en konkret, Nav-kompatibel arkitekturplan. Bruker beslutningstrær for å velge riktig auth, kommunikasjon, database og Nais-oppsett.
Workflow
- Velg arketype — hva slags ting bygges
- Gå gjennom beslutningstrær — auth, kommunikasjon, data, observerbarhet
- Velg teststrategi — riktig testnivå per komponent og endringstype
- Generer plan — Nais-manifest, prosjektstruktur, CI/CD
- Generer leveransedokumenter — endringsdokument, utrullingsplan, runbook
- Review — verifiser at valgene henger sammen
Steg 1: Arketype
| Arketype | Stack | Nais-type |
|---|---|---|
| Backend API | Kotlin/Ktor eller Spring Boot | Application |
| Hendelsekonsument | Kotlin + Kafka + Rapids & Rivers | Application |
| Frontend (innbygger) | Next.js + ID-porten + Wonderwall | Application |
| Frontend (saksbehandler) | Next.js + Azure AD + Wonderwall | Application |
| Batchjobb | Kotlin + scheduled | Naisjob |
| BFF (Backend-for-Frontend) | Next.js API routes | Application |
Endringstype
I tillegg til arketype, avklar om dette er nytt eller en endring:
| Endringstype | Ekstra beslutninger |
|---|---|
| Nybygg | Standard beslutningstrær (auth, data, kommunikasjon) |
| Modernisering | Migreringsstrategi, bakoverkompatibilitet, utrulling, dekommisjonering |
| Refaktorering | Karakteriseringstester, rollback-plan, parallellkjøring |
For modernisering og refaktorering — se modernization-patterns.md for konkrete mønstre og decision-trees.md for migreringsbeslutningstrær.
Steg 2: Beslutningstrær
Se decision-trees.md for alle beslutningstrær.

What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 11d ago First seen · 386 lines · 26 tokens per session scan A a10798e1cdc5
nav-plan is a skill published in the GitHub repository navikt/copilot (54 stars, last pushed today), licensed MIT. It adds 26 tokens to every session and 3,362 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.
