Data & AI

Setup Sentry AI Agent Monitoring in any project. Use this when asked to add AI monitoring, track LLM calls, monitor AI agents, or instrument OpenAI/Anthropic/Vercel AI/LangChain/Google GenAI. Automatically detects installed AI SDKs and configures the appropriate Sentry integration.

Strategies for evaluating agents in production - sampling, baselines, and regression detection

Use when the user asks for a plan or the task is complex/ambiguous. Enforces AGENTS.md workflow and encourages loading other relevant skills.

DDDアーキテクチャでHonoのバックエンドを新規実装または既存コードベースをリファクタリングする際のガイド。レイヤー構成（domain/application/infrastructure/controller）、依存方向、責務境界、Hono公式ミドルウェア/プラグインの活用、Hono OpenAPIプラグイン（hono-openapi）とzod-openapiの必須採用、Drizzle ORMの利用、トランザクション境界、エラーハンドリング、テスト指針、ESLint/Prettierの必須導入を含む。

Use when creating or editing skills, before deployment, to verify they work under pressure and resist rationalization - applies RED-GREEN-REFACTOR cycle to process documentation by running baseline without skill, writing to address failures, iterating to close loopholes

CSS custom properties theme architecture for 4 themes (studio, earth, athlete, gradient) with data-theme attribute switching and theme-aware components. Use when implementing theme switching, defining color schemes, or creating theme-responsive UI elements.

Analyzes and optimizes database queries for performance and efficiency

High availability templates and configs

Container security, secret management, compliance, and secure infrastructure.

Package Go CLIs as minimal secure containers with distroless base images. Static binaries, non-root users, read-only filesystems for production.

Build n8n nodes using programmatic style with full control over execution, data handling, and API calls. Use this skill when implementing execute() methods, creating helper functions for API requests, handling pagination with cursor-based logic, implementing loadOptions for dynamic dropdowns, processing binary data, building webhook or polling triggers, or handling complex data transformations. Apply when building trigger nodes, GraphQL integrations, non-HTTP protocols, or any scenario requiring custom execution logic.

Inverse Fast Fourier Transform for time domain reconstruction

Guide for creating and working in Git worktrees with a consistent workflow. Use when a user wants to run a task in a separate worktree, create or clean up worktrees, migrate a repo into a main/worktrees layout, or implement work based on an issue ID using GitHub/GitLab tooling.

Use when educators need to validate if their lesson plan covers all 3 Delegation subcategories (Problem/Platform/Task Awareness).Analyzes lesson plans and provides objective scores (0-10) with actionable feedback.Works in Claude.ai, Claude Code, and API for maximum portability.

Senior Backend Developer with 10+ years Java and 5+ years Spring Boot experience. Use when implementing Spring Boot features, writing Java code, creating REST APIs, working with databases (R2DBC, JPA), implementing business logic, or writing unit/integration tests.

Create GitHub issues from TASK-???.md files. Use when you need to bulk-create GitHub issues from task markdown files with frontmatter containing title, label, parent, and project attributes. Automatically extracts frontmatter, creates issues via gh CLI, links parent issues, and adds to specified projects.

Reviews finished and in-progress digital products to assess adherence to design specifications and discover potential issues with those specifications. Validates implementation against design intent, identifies visual and interaction discrepancies, and provides actionable feedback for design and engineering teams.

Real-time rope/cable physics using Position-Based Dynamics (PBD), Verlet integration, and constraint solvers. Expert in quaternion math, Gauss-Seidel/Jacobi solvers, and tangling detection. Activate on 'rope simulation', 'PBD', 'Position-Based Dynamics', 'Verlet', 'constraint solver', 'quaternion', 'cable dynamics', 'cloth simulation', 'leash physics'. NOT for fluid dynamics (SPH/MPM), fracture simulation (FEM), offline cinematic physics, molecular dynamics, or general game physics engines (use Unity/Unreal built-ins).

Adds reactive and declarative behavior to HTML with minimal JavaScript using Alpine.js directives. Use when adding lightweight interactivity to server-rendered pages, building interactive components without a build step, or when user mentions Alpine.js, x-data, or Tailwind-style reactivity.

Build production-grade FastAPI backends with SQLModel, Dapr integration, and JWT authentication.Use when building REST APIs with Neon PostgreSQL, implementing event-driven microservices withDapr pub/sub, scheduling jobs, or creating CRUD endpoints with JWT/JWKS verification.NOT when building simple scripts or non-microservice architectures.
