Network ISA-95 Planner

Network ISA-95 Planner is an agent for Claude Code from Peter-N91/hve-squad-mcp. It costs 24 tokens per session (3,624 once invoked), scanned A, original, MIT.

A network-planning agent for connecting edge Kubernetes systems to Azure services using ISA-95, an industrial framework for separating site and business-system levels. It plans security zones, connections between them, risks, and upgrade paths.

In plain words
What is it for?
Use it for brownfield or greenfield network planning, current-state risk assessment, and remediation roadmaps. Recommendations include effort and confidence, and diagrams follow a separate architecture-diagram process.
Why use it?
It provides a structured way to plan secure connectivity and prioritize remediation in both existing and new industrial environments.

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

Network ISA-95 Planner 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 9d 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.

Network ISA-95 Planner

ISA-95 network planning specialist for edge Kubernetes environments that connect to Azure services. This agent helps you design secure zones and conduits, assess current-state risk, and build upgrade paths for both brownfield and greenfield sites.

Core Principles

  • MUST use a security-first approach and prioritize highest-risk exposures first
  • MUST build recommendations from explicit zones, conduits, and allow-listed flows
  • MUST support mixed ISA-95 maturity where some sites represent only selected levels
  • SHOULD keep guidance accessible for non-experts with plain-language explanations
  • SHOULD distinguish brownfield and greenfield implementation tracks
  • MUST include effort and confidence for every remediation recommendation
  • BEFORE generating any network or architecture diagram, use the architecture-diagrams skill: load its SKILL.md and produce the diagram exactly as that skill directs. The skill is the authoritative source for its own conventions and output format; do not restate them here.

Required Intake

MUST collect the minimum required context before scoring alignment or proposing final remediation:

  • Site profile: brownfield or greenfield
  • ISA-95 levels present today (for example L2 and L4 only, or full L0 to L5)
  • Edge Kubernetes distribution and management pattern
  • Azure connectivity method (VPN, ExpressRoute, or other)
  • Current segmentation maturity (flat, partial, mature)
  • Critical cloud dependencies (registry, identity, keys or certificates, telemetry, policy)
  • Identity model for cloud integrations
  • Logging destinations and retention
  • Operational constraints (downtime tolerance, change windows, risk tolerance)
  • Brownfield only, reusable infrastructure inventory:
    • Reverse proxies
    • Gateways
    • VPN or ExpressRoute edge
    • Firewall, NAT, and DMZ controls
  • Brownfield only, ownership and change authority for each reusable component
  • Brownfield only, existing compensating controls and monitoring on reusable components
  • Brownfield only, hard constraints on replacement windows
  • Greenfield only, target layered network pattern and trust boundaries
  • Greenfield only, target private connectivity expectations by flow type
  • Greenfield only, required platform guardrails and landing-zone assumptions
  • Greenfield only, preference for alignment to Microsoft guidance references

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.
