Coding standards for readable, maintainable Java 17+ in Spring Boot services. \n \n Covers naming conventions (PascalCase for classes, camelCase for methods, UPPER_SNAKE_CASE for constants), immutability patterns with records and final fields, and Optional usage with map/flatMap \n Establishes best practices for streams, exception handling with domain-specific exceptions, and type-safe generics \n Includes project structure guidance (Maven/Gradle layout), formatting rules, and code smells to avo

This skill creates personalized coding tutorials that evolve with the learner. Each tutorial builds on previous ones, uses real examples from the current codebase, and maintains a persistent record of concepts mastered.

Behavioral guidelines to reduce common LLM coding mistakes, focusing on simplicity and clarity in coding practices.

Grounds every implementation decision in official documentation for authoritative, source-cited code.

Modern C# coding standards covering records, pattern matching, value objects, async/await, and high-performance patterns. \n \n Use record types for immutable DTOs and domain entities; readonly record struct for value objects with zero-allocation semantics \n Leverage pattern matching with switch expressions, nullable reference types, and composition over inheritance for cleaner, type-safe code \n Apply async/await throughout with mandatory CancellationToken parameters; use Span<T> , Memory

Records decisions and documentation for architectural choices, public APIs, and feature shipping to aid future engineers and agents.

Optimizes agent context setup for improved output quality during coding sessions.

Manage Twill Cloud Coding Agent workflows through the public v1 API. \n \n Create, list, retrieve, and manage tasks with support for custom branches, agent selection, and file attachments \n Stream job logs in real time via Server-Sent Events and cancel running jobs at any point \n Full lifecycle control: send follow-up messages, approve plans, archive tasks, and manage task state \n Schedule recurring coding tasks with cron expressions, timezone support, and pause/resume capabilities \n List re

Automate issue-to-Draft-PR pipeline by labeling issues for GitHub Copilot assignment. \n \n Label an issue with ai-copilot to trigger GitHub Actions, which auto-assigns Copilot via GraphQL and initiates code generation, branch creation, and Draft PR opening \n Requires GitHub Copilot Pro+, Business, or Enterprise; one-time setup deploys the workflow, registers a PAT secret, and creates the label \n Copilot PRs are treated as external contributions and require manual approval before CI runs; subs

This skill provides a set of core principles and practices for software development. Use this when implementing new features, refactoring existing code, or reviewing code to ensure high quality and maintainability.
