Design

Use when implementing reduced motion alternatives, vestibular-safe animations, WCAG compliance, or designing for users with motion sensitivity.

Guide decision-making using principles and trade-off analysis frameworks. Use when making technical decisions, evaluating alternatives, designing solutions, or choosing between options. Helps establish lasting principles.

This skill should be used when creating extensions for Claude Code or OpenCode, including plugins, commands, agents, skills, and custom tools. Covers both platforms with format specifications, best practices, and the ai-eng-system build system.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Use when completing tasks, implementing major features, or before merging to verify work meets requirements - dispatches superpowers:code-reviewer subagent to review implementation against plan or requirements before proceeding

Scaffolds new frontend pages/features with TDD approach, following established UI patterns from BuildProject/Baker pages. Generates page component, test file, updates routing, and maintains 90%+ test coverage before implementing production code. Use this when creating new pages or features in the Bucket app.

Comprehensive security specialist that performs vulnerability assessments, secure code reviews, dependency audits, and provides remediation guidance following OWASP, CWE, and industry security standards

This skill should be used when working with the Ghostmind development system, which uses meta.json as a central configuration for Docker, Compose, Terraform, and Tmux. Use this skill when creating or modifying configurations for any of these components, setting up new applications, or understanding how the system components interconnect.

build marp presentations

Generate properly configured tsconfig.json files for TypeScript projects with appropriate compiler options for various project types. Triggers on "create tsconfig", "generate tsconfig.json", "typescript config for", "configure TypeScript".

This skill should be used when the user asks to "add unit tests", "write tests", "set up Vitest", "create a utility function", "add test coverage", or mentions TDD, test-driven development, or testing utilities. Provides guidance for unit testing with Vitest in TypeScript/Next.js projects using TDD approach.

Security-focused code review guidelines for identifying vulnerabilities

Use this skill when exploring codebase architecture or planning new features requiring models/enums.AUTO-ACTIVATE when user mentions (FR/EN): - modèle, model, models, enum, enums, schema, Prisma schema - architecture, domain, domaine, existe, exists, available, disponible - créer, create, ajouter, add, nouveau, new, nouvelle feature - quel modèle, what model, which model,quel enum - 121 modèles, 87 enums, Planning, Leave, Business RulesThis skill provides INSTANT lookup (500 tokens vs 15k for full ERD) for 121 models and 87 enums.

Follow these patterns when designing guardrails validation contracts in OptAIC. Use for signal bounds, dataset schemas, portfolio constraints, PIT validation, and other domain-specific validation rules. Covers the "Law vs Police" architecture where Definitions contain contracts and the Engine enforces them.

Master system design and scalable architecture. Learn distributed systems, scalability patterns, high availability, and designing large-scale systems.

Guide for creating Claude Code hooks - shell commands that execute at specific lifecycle events (SessionStart, SessionEnd, PreToolUse, PostToolUse, etc.). Use when users want to automate actions, add validation, logging, or integrate external tools into Claude Code workflows.

Guide for adding new AI providers to ClaudeBar using TDD patterns. Use this skill when:(1) Adding a new AI assistant provider (like Antigravity, Cursor, etc.)(2) Creating a usage probe for a CLI tool or local API(3) Following TDD to implement provider integration(4) User asks "how do I add a new provider" or "create a provider for X"

Systematic architecture analysis following Understand → Research → Specify → Decompose → Plan workflow. Use for system design, solution evaluation, build vs buy decisions, and task decomposition. Activate when users say "design", "architect", "break down", "best approach", or "should I build".

Expert knowledge for UX Layer modeling in Documentation Robotics

Builds accessible UI with shadcn/ui including component installation, customization, theming, and Radix primitives. Use when adding UI components, customizing design systems, implementing accessible interfaces, or building component libraries.
