Guidelines for building server-side API routes in Expo Router with EAS Hosting, covering HTTP methods, dynamic routes, environment variables, CORS, error handling, local testing, and deployment.

This skill generates FastAPI router templates with authentication, response models, and HTTP status codes. It helps developers create standardized backend endpoints quickly by replacing placeholders for resource names and implementing security patterns.

Learn to build and deploy event-driven serverless applications using Google Cloud Functions Gen1 and Gen2. This skill covers configuring triggers for Pub/Sub, Cloud Storage, and Eventarc, as well as managing deployments via gcloud CLI. It includes examples for Python and Node.js runtimes, handling HTTP requests, scheduled tasks, and data processing pipelines without maintaining servers. Ideal for implementing serverless workloads on GCP.

This skill enables identification and testing of HTML injection vulnerabilities in web applications to assess security risks. It involves using tools like Burp Suite and understanding HTTP structures. Strictly for authorized security assessments, defensive validation, or educational purposes in controlled environments.

A skill for hunting CSRF vulnerabilities in web applications. Covers raw HTTP client techniques, token bypass methods, and high-value target identification, with an emphasis on authorized testing.

This skill helps identify gRPC security vulnerabilities during penetration testing. It includes fingerprinting gRPC servers, enumerating services via reflection, testing authentication bypasses, and checking for DoS risks like HTTP/2 Rapid Reset. Requires explicit authorization for offensive use.

This skill covers identifying and exploiting HTTP request smuggling vulnerabilities (CL.TE, TE.CL, H2.CL, H2.TE). It includes fingerprinting front-end servers, crafting payloads for cache poisoning, and harvesting credentials via backend desyncs. Requires authorization and defensive guidance protocols.

Build Model Context Protocol servers to enable LLMs to interact with external APIs and services. Supports Python (FastMCP) and Node/TypeScript (MCP SDK) for creating tools that help AI agents accomplish real-world tasks. Learn to design well-structured tools, manage context, and implement transport mechanisms like stdio or Streamable HTTP.

This skill provides expert guidance for writing JavaScript code within n8n Code nodes. It covers using $input, $json, and $node syntax, making HTTP requests with $helpers, and working with dates using DateTime. It helps with troubleshooting Code node errors and choosing between Code node modes. Use this for complex transformations, custom calculations, recursive operations, and data aggregation that simple nodes cannot handle.

This skill guides users on writing Python code within n8n Code nodes, focusing on standard library usage. It details critical limitations regarding external packages, offering workarounds for HTTP requests and data analysis. Users learn when to prefer Python over JavaScript and how to handle specific syntax requirements safely within the n8n environment.

Deploy long-running Node.js HTTP functions directly on Neon database branches. Automatically injects DATABASE_URL and runs compute next to your data. Ideal for stateful streaming, WebSocket servers, and agent backends that exceed traditional serverless limits. Managed via Neon CLI.

This skill guides users to configure and test common network services like HTTP, HTTPS, SNMP, and SMB within a controlled penetration testing lab environment. It covers service enumeration, log analysis, and security testing procedures. Users will learn to set up web servers, secure connections, and file shares while practicing defensive and offensive security techniques on properly configured target systems.
