dotnet-patterns is a practical .NET pattern guide for backend development. It helps you write and review idiomatic C# with stronger defaults for immutability, explicit dependencies, async/await, and maintainable ASP.NET Core services. Use it for code generation, refactoring, and review when you want repeatable patterns, not generic advice.

x-api helps you work with the X/Twitter API for posting, reading timelines, search, and basic analytics. It guides auth choices, endpoint selection, and request shape for API Development tasks, including bearer-token reads and OAuth 1.0a write flows.

Use the security-review skill to review auth, user input, secrets, APIs, payments, uploads, and other sensitive flows. It provides a practical security-review guide with clear pass/fail checks, risky-pattern examples, and a focused process for catching common issues before release.

nestjs-patterns is a practical NestJS architecture skill for building modular, production-grade TypeScript backends. It guides module structure, controller and service boundaries, DTO validation, guards, interceptors, config, testing, and the right way to organize code for maintainable Backend Development.

laravel-plugin-discovery helps you discover and evaluate Laravel packages via LaraPlugins.io MCP. Use it to assess package health, check Laravel/PHP compatibility, and find options for API Development before you install.

laravel-patterns helps you design Laravel apps with cleaner boundaries: thin controllers, services or actions for business logic, predictable Eloquent data access, and practical patterns for queues, events, caching, and API resources. It is built for backend development teams that need maintainable production apps, not quick one-off scaffolding.

documentation-lookup helps agents answer library, framework, and API questions from current docs instead of memory. It is ideal for setup, configuration, reference, and code-example tasks when the latest syntax matters. Use the documentation-lookup skill for Skill Docs when a request depends on live documentation and version-accurate guidance.

claude-api helps with Anthropic Claude API patterns for Python and TypeScript, including install, messages, streaming, tool use, vision, batches, prompt caching, model selection, and Claude Agent SDK workflows.

Use the benchmark skill to measure performance baselines, detect regressions before and after PRs, and compare stack alternatives across pages, APIs, and builds for Performance Optimization.

backend-patterns is a backend development skill for Node.js, Express, and Next.js API routes. It helps with API design, repository/service/controller layering, validation, caching, background jobs, and database optimization so you can build cleaner server-side systems with less guesswork.

api-connector-builder helps you add a repo-native API connector or provider by matching the host repository’s existing integration pattern, wiring, tests, and conventions.

api-design is a REST API design skill for planning and reviewing endpoints, resource naming, status codes, pagination, filtering, versioning, and error responses.

ai-regression-testing helps catch bugs AI-assisted development often misses, including incomplete fixes, stale assumptions, and regressions across sandbox and production paths. Use this ai-regression-testing skill for Regression Testing when an agent has changed API routes, backend logic, or bugfixes that need practical, repeatable checks. It is especially useful for DB-free sandbox-mode verification and review workflows that expose hidden branches.

claude-api is a practical skill for installing and using the Claude API and Anthropic SDKs. It helps developers choose the right SDK or raw HTTP path, detect language-specific docs, and implement streaming, tool use, files, batches, and error handling with less guesswork.

technical-writer is a lightweight documentation skill for creating clearer README files, API docs, setup guides, tutorials, onboarding docs, and release notes. It centers Technical Writing on user goals, quick starts, examples, and troubleshooting. The skill is delivered as a single SKILL.md file with no extra scripts or templates.

The fullstack-developer skill is a reusable prompt package for modern JavaScript and TypeScript web app work across React, Next.js, Node.js, APIs, databases, auth, and deployment. It is best for multi-layer planning and implementation, with a single SKILL.md file that defines scope and workflow rather than providing scripts or templates.

The cloud skill helps you install and use Browser Use Cloud for Browser Automation, including quickstart setup, v2 and v3 APIs, SDK usage, sessions, profiles, CDP connections, proxies, webhooks, and live monitoring.

mcp-builder is a guide skill for designing, implementing, and evaluating MCP servers in Python FastMCP or Node/TypeScript, with best practices for agent-friendly tools, schemas, pagination, errors, security, and evaluation.

zyte-api-automation helps agents run Zyte API workflows through Composio Rube MCP by discovering current tool schemas, checking the zyte_api connection, and executing Web Scraping tasks with less guesswork.

zenserp-automation helps agents run Zenserp tasks through Composio Rube MCP. Use it to connect Zenserp, discover current tool schemas first, and collect SERP data for SEO research.

veriphone-automation helps agents run Veriphone workflows through Composio Rube MCP by discovering current tool schemas, checking the Veriphone connection, and executing validated tasks without guessing parameters.

Uploadcare Automation helps agents manage Uploadcare files via Rube MCP and Composio: list uploads, filter by status or date, inspect metadata, get download URLs, store files, and work with file groups.

twocaptcha-automation is a Claude skill for using Twocaptcha through Composio Rube MCP. It guides agents to discover live tools, verify the connection, and follow current schemas before execution.

twelve-data-automation helps Claude agents automate Twelve Data workflows through Composio Rube MCP. It covers setup, active twelve_data connection checks, RUBE_SEARCH_TOOLS discovery, and schema-aware usage for Workflow Automation.
