Secure REST APIs with authentication, rate limiting, CORS, input validation, and security middleware. Use when building or hardening API endpoints against common attacks.
Advanced concurrency patterns for Tokio including fan-out/fan-in, pipeline processing, rate limiting, and coordinated shutdown. Use when building high-concurrency async systems.
Automatically discover API design skills when working with REST APIs, GraphQL schemas, API authentication, OAuth, JWT, rate limiting, API versioning, error handling, or endpoint design. Activates for backend API development tasks.
Better Auth framework reference — configuration, security, rate limiting, sessions, plugins, and production hardening. Use when configuring Better Auth, auditing auth security, adding plugins, or troubleshooting Heartwood.
Framework-agnostic debouncing, throttling, rate limiting, queuing, and batching utilities.
Guide REST API integration including HTTP methods, authentication, error handling, and rate limiting. Use this skill when the user needs to connect to a third-party API, design an API client, troubleshoot API errors, or understand API concepts — even if they say 'connect to this API', 'why is the API returning errors', 'how do I authenticate', or 'build an API integration'.
Automatic LLM provider failover with fallback chains, inspired by OpenClaw/ZeroClaw model configuration.
OpenAI-compatible proxy aggregating 14 free-tier LLM providers with automatic failover and per-key rate tracking.
Add Arcjet Guard protection to AI agent tool calls, background jobs, queue workers, and other code paths where there is no HTTP request. Covers rate limiting, prompt injection detection, sensitive information blocking, and custom rules using `@arcjet/guard` (JS/TS) and `arcjet.guard` (Python). Use this skill whenever the user wants to protect tool calls, agent loops, MCP tool handlers, background workers, or any non-HTTP code from abuse — even if they describe it as "rate limit my tool calls," "block prompt injection in my agent," "add security to my MCP server," or "protect my queue worker" without mentioning Arcjet or Guard specifically. Uses the Arcjet CLI (`npx @arcjet/cli` or `brew install arcjet`) for authentication and site/key setup.
API Gateway patterns (Kong, Traefik, AWS API Gateway) — rate limiting, auth, routing, versioning. Use when implementing API gateway, reverse proxy, or API management.
