A comprehensive guide to writing idiomatic and efficient Go code. It covers best practices for error handling (using `%w`), managing slices and maps, implementing robust concurrency with goroutines and channels, designing small composable interfaces, and avoiding common anti-patterns. Essential for improving code quality in Go projects.

This comprehensive guide details the idiomatic and efficient way to write Scala code. It covers crucial modern practices, such as utilizing functional transforms over traditional loops, embracing pattern matching, using Option/Either for robust error handling instead of null checks or exceptions, and managing concurrency safely. Essential reading for any Scala developer aiming for high-quality, maintainable, and performant codebases.

A comprehensive guide to creating a robust API versioning strategy document. It helps service teams define consistent rules for evolving their APIs over time, covering versioning schemes (URL path, headers), lifecycle policies (Stable, Deprecated, Sunset), and classifying breaking changes. Essential for maintaining backward compatibility and managing API deprecation.

This skill generates a complete, actionable CI/CD playbook, thoroughly documenting the entire software deployment lifecycle. It covers essential stages like build & linting, unit/integration testing, security scanning, and phased deployment to staging and production. The output provides clear guidelines on required inputs, automated gates, manual approvals, and necessary rollback procedures, which is crucial for engineering documentation and team onboarding.

A comprehensive guide and playbook for managing feature flags across services or teams. It covers flag taxonomy (Release, Experiment, Ops, Permission), naming conventions, safe rollout strategies, creation checklists, and cleanup policies to prevent technical debt. Ideal for standardizing feature flag practices and governance.

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.

A comprehensive guide for designing and implementing 3D user interfaces across web, mobile, and cross-platform environments. Learn core principles like perspective transformations, Z-axis depth, and interactive rotation to build visually stunning, spatially immersive, and highly engaging product experiences.

Master the end-to-end process of creating Power BI paginated reports using the RDL format. This skill provides guidance on developing print-faithful, multi-page documents like invoices and statements. It covers initial requirements interviews, understanding the core RDL XML structure, best practices for validation, and the critical final rendering and publishing steps in the Power BI Service or Fabric.

This skill provides comprehensive guidance for developing professional, interactive, and distributable Power BI developer visuals (.pbiviz). It covers the entire workflow using the pbiviz toolchain, including scaffolding the project, implementing the IVisual class using TypeScript, managing the formatting model, live-previewing, packaging, certifying, and finally publishing the visual to AppSource.

Programmatically manage your entire contact database within Mailtrap. This guide covers using the API to create, update, delete, and bulk import contacts. It is essential for synchronizing contact data with CRMs, triggering custom automation events, building targeted segments, or performing large-scale list cleanups.

Use Mailtrap Email Sandbox to capture and inspect outbound emails without sending them to real recipients. This is crucial for development, staging, and CI/CD environments. It allows developers to test email content, headers, attachments, and spam scores using dedicated APIs, SMTP settings, or SDKs, ensuring mail integrity before deployment. Ideal for automation and rigorous quality checks.

This document provides a comprehensive guide to the principles and vocabulary needed to write high-quality, predictable, and effective skills. It covers advanced concepts like model-invoked vs. user-invoked skills, managing context load, structuring information hierarchies (steps vs. reference), and implementing progressive disclosure to improve agent predictability.
