backend-development-nodejs

backend-development-nodejs is a skill for Claude Code from aAAaqwq/AGI-Super-Team. It costs 37 tokens per session (380 once invoked), scanned A, original, MIT.

A Node.js backend development guide covering NestJS, Express, Koa, databases, Redis, GraphQL, and real-time communication. Node.js runs JavaScript or TypeScript on the server; a backend provides application services and APIs.

In plain words
What is it for?
Building APIs and services with NestJS, Express, or Koa; using Prisma or TypeORM; adding GraphQL or Socket.io; and working with Redis and TypeScript.
Why use it?
It helps choose a server framework and apply consistent patterns for validation, errors, database access, asynchronous work, and tests. It also brings common Node.js tools into one reference.

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

backend-development-nodejs 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.

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.
