Comprehensive guide for building Agent Skills according to agentskills.io specification. Use when developers need to create, structure, or validate skills that follow the Agent Skills standard format and best practices.

Spec Kit を使って要件定義や仕様作成（仕様策定・仕様書作成・仕様設計を含む）を新規作成または既存仕様へ追記し、spec.md/plan.md/tasks.mdまで生成・更新する。要件定義、要件追加/変更、TDD前提の要件整理、仕様の明文化、Spec Kitのspecify/clarify/plan/tasksフロー実行が求められるときに使用。

Design database schemas for PostgreSQL, Neon, Convex, or Supabase. Use when users need to create tables, define relationships, plan migrations, optimize indexes, or implement data models. Covers normalization, denormalization strategies, and platform-specific features.

Turn the model into a SQLAlchemy-focused Python coding agent for designing models, writing queries, debugging database issues, and integrating SQLAlchemy with Alembic and FastAPI in new or existing Python projects.

Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.

Kalahari architecture patterns and key classes. Use for code analysis and design.

Build Kubernetes-native CLIs in Go with type safety, testability, and complex orchestration logic for deployment tools and cluster automation.

Automatically generates comprehensive test suites (unit, integration, E2E) based on code and past testing patterns. Use when user says "write tests", "test this", "add coverage", or after fixing bugs to create regression tests. Eliminates testing friction for ADHD users.

Production-ready code implementation following approved designs. Writes clean,tested, documented code. Zero linting violations. All code includes tests.

Production-grade text search algorithms for finding and matching text in large documents with millisecond performance. Includes Boyer-Moore search, n-gram similarity, fuzzy matching, and intelligent indexing. Use when building search features for large documents, finding quotes with imperfect matches, implementing fuzzy search, or need character-level precision.

Create emotionally compelling murder mystery narratives using Danpyeonsun methodology and K-drama storytelling principles. Designs 3-act dramatic structures, complex morally-gray characters, bittersweet endings, and scene-by-scene emotional beats. Use when writing scenarios for detective games, designing murder mystery plots, or creating K-drama style narratives with moral complexity.

macOS UI automation and screenshot capture tool. Use when working with macOS applications and needing to: (1) Capture screenshots with UI element annotations, (2) Automate UI interactions (clicking, typing, scrolling), (3) Control applications and windows programmatically, (4) Navigate menus and dialogs, (5) Perform visual analysis of screens, (6) Create multi-step automation workflows. Requires macOS 15.0+ with Screen Recording and Accessibility permissions.

Send BSV transactions using @bsv/sdk. Build, sign, and broadcast transactions to the BSV blockchain.

Default testing standard for all implementation work - ensures code actually works through mandatory execution validation before confirming to user. Applies automatically whenever writing, modifying, debugging, or implementing any code (scripts, APIs, UI, configs, data operations, logic changes). This is the baseline expectation, not an optional extra - every implementation must be verified through actual execution, not assumed correct.

Guia implementação de breadcrumb de navegação hierárquica seguindo padrões de acessibilidade WCAG e design system do Ultrathink

Implement ng-alain theming system with layout configuration, responsive design, menu management, and settings drawer for ng-lin project

Create and modify combat system components for SHINOBI WAY game following the dual-system architecture (CombatCalculationSystem + CombatWorkflowSystem). Use when user wants to add new combat mechanics, damage formulas, status effects, mitigation logic, turn phases, or refactor existing combat code. Guides through proper separation of pure calculations vs state management.

PyTorch CUDA environment and performance guidance, with emphasis on CUDA 13 toolkit/driver requirements, PyTorch wheel compatibility, and runtime checks. Use when configuring PyTorch on NVIDIA GPUs, debugging CUDA setup, or migrating to CUDA 13; triggers: pytorch cuda, cuda 13, driver version, nvcc, torch.version.cuda, tf32, streams.

Optimizes token usage and context management for large tasks, cleanup operations, multi-step workflows, code audits, and complex agent operations. Automatically triggers when handling cleanup commands, large codebase analysis, multi-file operations, or tasks requiring multiple subagents. Enforces efficient context usage while maintaining quality results.

Use when building or working with Mastra agents - establishes best practices for agent development, tool creation, and workflow orchestration
