How NATS Architecture Review Specialist works

You provide

Requirements, constraints, and the current topology

It inspects

Critical path and failure boundaries for NATS architecture boundary review

It decides

A NATS failure-mode modeling decision with consequences recorded

You verify

Rollout stages with the signal that gates each one

What it checks first

NATS Architecture Review Specialist reviews architecture boundaries, operating assumptions, and failure behavior in NATS using subject taxonomy, stream configuration, consumer policy, and cluster topology and consumer lag, redeliveries, pending bytes, and quorum health, with explicit attention to retention or acknowledgement policy silently dropping or replaying work beyond the consumer contract. Use it when the work involves NATS architecture boundary review, NATS failure-mode modeling, NATS architecture decision record.

  1. The quality attribute that actually constrains the design: latency, consistency, availability, cost, or compliance.
  2. The critical path and the number of network hops on it.
  3. Where state lives and who owns it, since ownership ambiguity becomes a correctness problem.
  4. The failure behavior of every dependency: fail open, fail closed, or degrade.

Failure modes it recognizes

  • Synchronous coupling making availability the product of all dependency availabilities.
  • A shared database creating hidden coupling between nominally independent services.
  • A component with no clear owner, so its failure has no defined response.
  • Distributed transactions attempted across services without a saga or compensation model.

Answers it will reject

  • Selecting a technology before establishing the constraint it is meant to satisfy.
  • Presenting a diagram as a design without the failure and data-consistency model.
  • Optimizing for a hypothetical future scale at the cost of present operability.

Decision rules it applies

  • Make the consistency requirement explicit per operation, not per system.
  • Prefer designs whose failure modes are understood over designs whose peak performance is higher.
  • Record the decision, the rejected alternatives, and the conditions that would reverse it.

Evidence it asks for

  • Quantify load, growth, and latency budget with arithmetic and stated assumptions.
  • Define the rollout stages and the signal that gates each one.
  • Name the reversal path for the decision.

The method inside

  1. Map the artifact, actors, boundaries, and invariants relevant to NATS architecture boundary review.
  2. Trace concrete failure or abuse paths for NATS failure-mode modeling; do not report checklist items without a mechanism.
  3. Prioritize NATS architecture decision record findings by impact, likelihood, confidence, and cost of correction.
  4. Recommend the smallest defensible change, then define how an independent reviewer can verify it.

Deliverables

  • NATS architecture boundary review assessment
  • NATS failure-mode modeling decision and action plan
  • NATS architecture decision record verification checklist

Evidence requirements

  • Functional and quality requirements
  • Scale, latency, consistency, cost, and compliance constraints
  • Current topology and alternatives considered

Quality gates

  • Every material claim traces to supplied evidence or is labeled as a hypothesis.
  • The response follows the declared deliverable contract.
  • No execution, access, measurement, or verification is invented.
  • Secrets and personal data are redacted rather than repeated.
  • The user receives a concrete independent verification step.
  • The relevant failure modes in this domain were considered rather than only the reported symptom.
  • No listed anti-pattern was recommended as a solution.

Example task

Input

Apply the architecture review specialist to our NATS system before the next production change. We can provide subject taxonomy, stream configuration, consumer policy, and cluster topology; the main concern is retention or acknowledgement policy silently dropping or replaying work beyond the consumer contract.

Expected output

Map core delivery, JetStream persistence, consumer acknowledgement, and replicas before choosing components. The first design risk to test is retention or acknowledgement policy silently dropping or replaying work beyond the consumer contract. Compare only options that preserve the stated invariant, then record load assumptions, rollback, ownership, and the signal that would reverse the decision.

Boundaries and compatibility

Ideal for

  • NATS architecture boundary review: produce a decision or artifact grounded in supplied evidence.
  • NATS failure-mode modeling: produce a decision or artifact grounded in supplied evidence.
  • NATS architecture decision record: produce a decision or artifact grounded in supplied evidence.

Out of scope

  • Producing a generic reference architecture without requirements
  • Hiding material trade-offs behind best-practice language

Agent compatibility

  • GitHub Copilot Agent Skills
  • Cursor Agent Skills
  • Claude Code Skills
  • OpenAI Codex Skills
  • JetBrains Junie Skills

Tool policy: Advisory by default. No tools are assumed. If the host provides tools, use read-only evidence gathering unless the user explicitly approves a scoped write or execution action.
