An Agent Skill for Arcjet — the runtime security platform that ships with your code.
Gives AI coding agents the knowledge to add Arcjet security protection to any project. Works in VS Code (GitHub Copilot), Claude Code, Cursor, and any other compatible agent.
npx skills add arcjet/skillsThe 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.
Dedicated Python Guard integration skills cover official LangChain, CrewAI, OpenAI Agents, Claude Agent SDK, Claude Managed Agents, and Strands Agents adapters. JS Guard adapters are per-file references inside the arcjet skill (references/guards_js_*.md) — load fundamentals plus exactly one adapter. Shared fundamentals stay in the arcjet skill. HTTP frameworks are not separate skills.

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.
