Asked for a durable JetStream pull-consumer snippet with proper shutdown: baseline used the well-known but wrong nc.Close() and skipped dedup/backoff config, while the skill-guided version caught that exact footgun via its own Common Mistakes table (nc.Drain(), js.Publish() with Nats-Msg-Id, Nak() on failure) -- a concrete production-correctness fix, not just restating docs.
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 NATS does
A self-contained reference for building on NATS: Core NATS pub/sub, request/reply, and queue groups; JetStream streams, pull/push consumers, KV and object stores; connection/reconnect options; NKey/JWT security and subject permissions; server config, clustering, leaf nodes, and Go embedding. Three deep-dive reference files (jetstream.md, security.md, server-deployment.md) live alongside SKILL.md and cover full struct fields, decision trees, and Docker/Kubernetes/Helm configs. Triggers on any NATS/JetStream development, deployment, or messaging-protocol microservice question.
How to install NATS
git clone https://github.com/kaustavdm/nats-skill
cd nats-skill
mkdir -p ~/.claude/skills
cp -r skills/nats ~/.claude/skills/nats
Skills live in ~/.claude/skills/ (global) or .claude/skills/
(per-project). Restart Claude Code after installing.
Commands — how to trigger NATS
-
/natsDense NATS/JetStream reference covering streams, consumers, KV, security, clustering, and a common-mistakes table.
It also activates on plain-language prompts like these:
-
write a durable JetStream pull consumer with proper shutdown handling -
set up NKey security and subject permissions for my NATS cluster -
how do I configure a NATS KV store with leaf node clustering
Frequently asked questions
- Is the NATS skill free?
- Yes. The skill itself is free from kaustavdm/nats-skill. SkillProof publishes the install command and an independent test verdict at no cost.
- Does NATS work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 15, 2026. Verdict: Tested · Works. Asked for a durable JetStream pull-consumer snippet with proper shutdown: baseline used the well-known but wrong nc.Close() and skipped dedup/backoff config, while the skill-guided version caught that exact footgun via its own Common Mistakes table (nc.Drain(), js.Publish() with Nats-Msg-Id, Nak() on failure) -- a concrete production-correctness fix, not just restating docs.
- What is the NATS 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 NATS?
- 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 NATS 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.
