Frontend

This skill provides comprehensive knowledge for working with the Anthropic Claude Agent SDK. It should be used when building autonomous AI agents, creating multi-step reasoning workflows, orchestrating specialized subagents, integrating custom tools and MCP servers, or implementing production-ready agentic systems with Claude Code's capabilities.Use when building coding agents, SRE systems, security auditors, incident responders, code review bots, or any autonomous system that requires programmatic interaction with Claude Code CLI, persistent sessions, tool orchestration, and fine-grained permission control.Keywords: claude agent sdk, @anthropic-ai/claude-agent-sdk, query(), createSdkMcpServer, AgentDefinition, tool(), claude subagents, mcp servers, autonomous agents, agentic loops, session management, permissionMode, canUseTool, multi-agent orchestration, settingSources, CLI not found, context length exceeded

Coordinate multi-agent software development from requirements through verified implementation using spec-driven workflows. Use when planning features, creating technical specifications, implementing complex tasks through specialized agents, or managing spec-dev workflows (PLAN/BUILD/ITERATE).

Use when building frontend Web apps that talk to CloudBase Relational Database via @cloudbase/js-sdk – provides the canonical init pattern so you can then use Supabase-style queries from the browser.

Comprehensive SaaS architecture planner for Next.js + Supabase applications. Converts ideas into production-ready technical plans with database schemas, file structures, feature breakdowns, and week-by-week development roadmaps. Use when planning subscription-based applications, multi-tenant SaaS products, or building from idea to launch.

Debug .NET/ABP and React applications with systematic root cause analysis. Use when: (1) investigating bugs or errors, (2) analyzing stack traces, (3) diagnosing N+1 queries, (4) fixing async deadlocks, (5) resolving React state issues.

Guidelines for preparing changelog entries for nextest releases following Keep a Changelog format

Phase 2 of OSS contribution - Deep analysis combining issue requirements with codebase exploration. Extracts requirements, explores code structure, identifies exact code locations to fix, traces execution paths, and maps code-level changes needed. Use when starting work on selected issue.

This skill should be used when setting up, configuring, or initializing Tailwind CSS (v3 or v4) and shadcn/ui for Next.js 16 App Router projects. Configure dark mode, design tokens, base layout with header/sidebar, accessibility defaults, and generate example components. Includes comprehensive setup automation, theme customization, and production-ready patterns. Use when the user requests "setup Tailwind", "configure shadcn/ui", "add dark mode", "initialize design system", or "setup UI framework" for Next.js projects.

Expert code reviewer for TypeScript + React 19 applications. Use when reviewing React code, identifying anti-patterns, evaluating state management, or assessing code maintainability. Triggers: code review requests, PR reviews, React architecture evaluation, identifying code smells, TypeScript type safety checks, useEffect abuse detection, state management review.

Generate new MCP tools for GitLab operations following the project's standardized pattern. Creates complete TypeScript files with imports, registration functions, Zod schemas, error handling, and format options. Supports simple CRUD operations, complex multi-action tools, and advanced patterns like discussion management. Use when "create mcp tool", "generate gitlab tool", "new tool for", "add tool to gitlab", or building new GitLab integration features.

Guide for creating Claude Code hooks. This skill should be used when users want to create, modify, or troubleshoot hooks that automate actions at specific points in Claude Code's workflow, such as validating code before commits, running linters after edits, or protecting sensitive files.

Generate HTML research reports with embedded data, charts, and analysis.Use when creating final research deliverables. Supports single comprehensivereports or multiple focused reports. Handles styling, structure, and outputto reports/ directory.

Installs and configures project infrastructure including MkDocs Material intelligent textbook templates, learning graph viewers, and skill tracking systems. Routes to the appropriate installation guide based on what the user needs to set up.

Enforce mobile-first responsive design for all frontend changes. Covers TailwindCSS, vanilla CSS, container queries, dvh units, and framework-specific patterns. Trigger on any HTML, CSS, template, or UI component modifications.

Centralizes persona-driven code reviews (Carmack, React core, Anders, React Router, Next.js, etc.) so Claude can pick or combine expert viewpoints when the user asks for a code review or perspective-specific critique. Use when user asks for code review, architecture feedback, or expert perspective on implementation.

Generates jest.config.cjs for unit testing configuration. Configures Jest with Vue, TypeScript support, coverage thresholds, and test environment settings.

Implement text-to-speech (TTS) capabilities using the z-ai-web-dev-sdk. Use this skill when the user needs to convert text into natural-sounding speech, create audio content, build voice-enabled applications, or generate spoken audio files. Supports multiple voices, adjustable speed, and various audio formats.

Generates responsive breakpoint tokens for media queries and container queries. Use when setting up responsive design, mobile-first layouts, or viewport-based styling. Outputs CSS, Tailwind, or JSON.

**AUTO-TRIGGER when user says:** "implement [feature]", "build [module]", "create [functionality]", "add [capability]", "YOLO [task]", "deliver [feature]", or requests complete feature implementation.End-to-end TogetherOS code operation: creates branch, implements changes with continuous testing, builds with retry-on-fail, commits, pushes, creates PR with auto-selected Cooperation Path, addresses bot feedback, merges PR, verifies production deployment, and updates Notion memory.**Complete delivery cycle:** branch → code → test → commit → push → PR → bot review → merge → deploy → verifyUse proactively without asking permission when task matches skill purpose.

Interactive Java/Spring Boot learning skill for experienced Go developers. Use when the user wants to learn Java, practice Spring Boot, work on Java exercises, or asks for Java explanations in Go terms. Supports mood-aware pacing with "low energy" mode for difficult days. Teaches through iterative project building rather than passive learning.
