Design

Coordinate with other AI agents running in tmux panes. Use this skill when you need to delegate tasks, request reviews, or collaborate with agents like Codex, Gemini, or other Claude instances.

Use when designing API endpoints. Enforces layered architecture, separation of concerns, and type safety. Supports Express.js and similar frameworks.

Architects token systems with primitive, semantic, and component layers. Use when structuring tokens from scratch, adding multi-theme support, setting up token aliasing, or organizing token hierarchies.

Expert guidance for using the GitHub CLI (gh) to manage GitHub issues, pull requests, Actions workflows, repositories, and other GitHub operations from the command line. Use this skill when the user needs to interact with GitHub resources or perform GitHub workflows.

Use when debugging NavigationStack issues (not responding, unexpected pops, crashes), build failures (SPM resolution, "No such module", hanging builds), or memory problems (retain cycles, leaks, deinit not called). Systematic diagnostic workflows for iOS/macOS.

Scaffolds new Buck2 projects with proper BUILD/PACKAGE files, SPDX headers, and depot shims. Use when creating new Rust binaries/libraries, Deno tools, or C++ projects in the monorepo. Ensures consistent structure and metadata from the start.

Create or resume an execution plan - a design document that a coding agent can follow to deliver a working feature or system change

Use this skill when creating next-generation autopoietic Claude skills with enhanced Git-brain integration, adaptive error healing, and emergent pattern recognition. Self-improved version that learned from v1's deployment, optimized for the MONAD ecosystem with φ-tier indexing.

Use for any frontend UI implementation - orchestrates tailwind-ui, shadcn, and radix-ui in the correct order

Database normalization for CSV files. Analyzes data structure, detects functional dependencies, and decomposes into normalized tables (1NF-BCNF). Outputs multiple CSV files, SQL DDL, and Mermaid ERD. Use when: (1) converting flat CSV data into relational database schema, (2) reducing data redundancy, (3) preparing denormalized exports for database import, (4) user mentions "normalize", "1NF/2NF/3NF/BCNF", "functional dependencies", or "database design".

Define and maintain clean architecture for the .NET 8 WPF widget host app. Use when shaping solution structure, layer boundaries, dependency rules, DI wiring, and project layout to keep UI, application, domain, and infrastructure separated.

Generate Prisma schema files with models, relations, enums, and database configuration for TypeScript ORM setup. Triggers on "create Prisma schema", "generate Prisma model", "prisma.schema for", "database schema Prisma".

A comprehensive guide to using ripgrep, a fast command-line search tool that recursively searches directories for regex patterns with automatic filtering and rich output options. Use when searching codebases, filtering files by type, or performing complex pattern matching across large directory structures.

Neon serverless Postgres with autoscaling, instant database branching, and zero-downtime deployments. Use when building serverless applications, implementing database branching for dev/staging, or deploying with Vercel/Netlify.

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.
