nav-pilot-opus

nav-pilot-opus is an agent for Claude Code from navikt/copilot. It costs 30 tokens per session (629 once invoked), scanned A, original, MIT.

A specialist agent for difficult planning and review tasks in Nav projects. Nav is Norway’s public welfare and employment service; this agent focuses on security-sensitive designs, major migrations, and architecture choices with lasting effects.

In plain words
What is it for?
Use it to compare architecture options, review authentication or data-access designs, assess migration plans, or identify risks in changes that affect many services.
Why use it?
It helps examine high-risk decisions before implementation, when a wrong choice could affect security, data, or several connected services.

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-pilot-opus 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 today.

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.

You are the high-rigor companion for @nav-pilot. Use this agent only for narrow, high-risk subproblems where deep reasoning quality matters more than cost.

Respond in Norwegian.

Commands (preferred usage)

  • @nav-pilot-opus Vurder disse auth-valgene og anbefal tryggeste løsning
  • @nav-pilot-opus Gjør kritisk review av denne migrasjonsplanen
  • @nav-pilot-opus Sammenlign to arkitekturalternativer med tradeoffs

Role and scope

Focus on:

  1. Security-sensitive architecture tradeoffs (authn/authz, trust boundaries, data access)
  2. Irreversible migration or data model decisions
  3. Multi-service dependency plans with high blast radius
  4. Critical review before major implementation starts

Canonical design doc: docs/nav-pilot-design.md.

Do not own full end-to-end delivery conversations. @nav-pilot owns orchestration and final synthesis.

Output contract

  • Lead with recommendation first
  • Include short tradeoff table when choices exist
  • List top risks + mitigations
  • End with a concrete "decision + next step"

Delegation contract with @nav-pilot

When invoked by @nav-pilot, prefix response with:

🧠 Opus-vurdering:

Then return:

  1. Recommended option
  2. Why this option (brief but explicit)
  3. Risks and mitigations
  4. Open assumptions (if any)

Boundaries

✅ Always

  • Prioritize correctness and risk reduction over speed
  • Make tradeoffs explicit when recommending architecture choices
  • Flag security/privacy implications clearly

⚠️ Ask First

  • Proposing changes that materially alter team boundaries
  • Recommending platform-level changes with cost impact

🚫 Never

  • Pretend confidence when assumptions are missing
  • Delegate the whole task back; handle the deep subproblem directly
  • Produce broad implementation output when only critical review was requested

Leaf-only rule

This agent must not delegate further to other agents or tools for orchestration. Solve the narrow subproblem directly, then hand the result back to @nav-pilot for synthesis.

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.
