Skill UI

This utility provides an extension point to inject custom query parameters into all live preview URLs generated by the Website Builder. Developers can use this to automatically append necessary data, such as signed tokens, tenant identifiers, or feature flags, ensuring the preview environment is fully configured for specific use cases. It supports complex async operations like fetching tokens from remote APIs.

This skill allows users to query the current state of various AWS resources (including EC2, S3, Lambda, RDS, VPC, etc.) using natural language. It translates user intent into strictly read-only AWS CLI commands (e.g., `describe-*`, `list-*`). Crucially, this tool can only view data and is contractually incapable of performing any write, modify, delete, or mutation actions, ensuring maximum safety.

Skill for working with Power BI reports using the pbir CLI. It covers exploring, building, managing, formatting, validating, and publishing reports, as well as driving Power BI Desktop for refresh and screenshots, and querying semantic models.

Expert guidance for the cross-platform Tabular Editor CLI (`te`) to scaffold, inspect, edit, validate, query, deploy, refresh, and test Power BI / Analysis Services semantic models from the terminal, including TMDL/BIM conversion, BPA, DAX testing, and CI/CD pipelines.

This skill is a comprehensive tool for managing and understanding SQL queries. It can explain complex SQL in plain English for non-technical stakeholders, optimize slow queries by identifying performance bottlenecks, generate functional SQL code from natural language prompts, and produce detailed query documentation and data dictionaries. Supports major dialects including PostgreSQL, MySQL, and BigQuery.

This skill provides comprehensive, read-only access to the pkg.go.dev API using the `godig` tool. It allows users to query detailed information about Go packages and modules, including full documentation, API signatures, available versions, dependency graphs, and known security vulnerabilities. It is essential for researching the external Go ecosystem and comparing library metadata.

This skill validates the correctness and completeness of any API request. It rigorously checks the HTTP method, URL structure, required headers, body format, authentication details, and query parameters. Use it to debug cURL commands, verify endpoint calls, or ensure API structures adhere to best practices, providing immediate, actionable feedback on required fixes.

Utilize this skill to assess the health, adoption, and performance metrics of published EAS Updates directly via the CLI. It reports critical data points including crash rates, unique user counts, install volumes, payload size, and the split between embedded and OTA users, making it essential for post-publish monitoring and regression detection.

EAS Observe is a comprehensive tool for monitoring performance metrics in production Expo applications. It tracks critical performance data, including app startup time, navigation performance across routes, and custom user events. Developers can integrate it into their Expo project using the `expo-observe` package and query detailed reports via the EAS CLI, ensuring optimal user experience and stability.

A comprehensive discipline for managing the write path in React or React Native applications using a query/cache layer. It codifies the full optimistic update lifecycle, ensuring that UI updates feel instantaneous, rollbacks are verbatim upon failure, and the global cache remains perfectly coherent across all components and list views. This pattern is essential for complex, highly interactive user experiences.

This guide details best practices for implementing robust, type-safe GraphQL queries and mutations. It covers using separate .gql files, running code generation tools, and implementing mandatory error handling (onError) and loading states. Use this when building complex, reliable data fetching layers with Apollo Client.

A comprehensive guide covering scalable backend architecture patterns, including Repository, Service, and Middleware design. It details best practices for building robust APIs using Node.js, Express, and Next.js. Topics covered include RESTful API structuring, database query optimization (preventing N+1 issues), implementing database transactions, and integrating caching strategies like Redis. This guide is essential for developing high-performance, maintainable server-side applications.
