Skill answer nailed specifics a generic answer glossed over: the exact $JS.EVENT.ADVISORY.CONSUMER.MAX_DELIVERIES subject for wiring a real DLQ, the default 2m DuplicateWindow, and a concrete backoff ladder — baseline covered the shape of the design but not these load-bearing details.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 8/10
  • Docs & honesty 5/5

What Jetstream Architecture does

Guides an agent through designing NATS JetStream systems: subject namespace, stream retention/storage, pull vs push consumers, ack/backoff/DLQ strategy, and idempotent exactly-once publishing. Triggers on JetStream-specific asks (stream config, consumer types, fanout/work-queue patterns) and on generic 'build a message queue / event stream on NATS' requests; explicitly defers Kubernetes/deployment and monitoring/troubleshooting questions to sibling skills in the same repo.

How to install Jetstream Architecture

git clone https://github.com/lithqube/nats-jetstream-claude-skills
cd nats-jetstream-claude-skills
mkdir -p ~/.claude/skills
cp -r jetstream-architecture ~/.claude/skills/jetstream-architecture

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Jetstream Architecture

  • /jetstream-architecture Designs NATS JetStream streams, subjects and consumers, with working Go/JS/Python code.

It also activates on plain-language prompts like these:

  • Design a JetStream setup for our order-processing events
  • I need a durable pull consumer with exactly-once delivery
  • Set up NATS streams for created/paid/shipped order events

Frequently asked questions

Is the Jetstream Architecture skill free?
Yes. The skill itself is free from lithqube/nats-jetstream-claude-skills. SkillProof publishes the install command and an independent test verdict at no cost.
Does Jetstream Architecture work with Claude Code?
We tested it with Claude Code 2.x (agent harness) on Jul 14, 2026. Verdict: Tested · Works. Skill answer nailed specifics a generic answer glossed over: the exact $JS.EVENT.ADVISORY.CONSUMER.MAX_DELIVERIES subject for wiring a real DLQ, the default 2m DuplicateWindow, and a concrete backoff ladder — baseline covered the shape of the design but not these load-bearing details.
What is the Jetstream Architecture SkillProof Score?
9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.
How do I install Jetstream Architecture?
Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
Can I use Jetstream Architecture with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
