The Arcjet skill for AI coding agents. Adds protection across HTTP route handlers, AI agent tool calls, MCP servers, background jobs, and queue workers — rate limiting, bot detection, email validation, prompt injection detection, sensitive information blocking, content moderation, and abuse prevention — and verifies decisions via the Arcjet CLI, MCP server, and Console. Works in JavaScript/TypeScript, Python, and Go across Next.js, Express, Fastify, SvelteKit, Remix, Bun, Deno, NestJS, FastAPI, Flask, net/http, and non-HTTP contexts.

This skill is also bundled by the
Arcjet plugin, which packages it as
a slash command for Claude Code and Cursor (alongside MCP integration and a
security-analyst agent). Choose the plugin if you want the bundled experience;
choose the direct skill install (npx skills add arcjet/skills) for
portability across any agentskills.io-compatible
client.
