Conduct a comprehensive architecture review of your codebase, evaluating system design, scalability, maintainability, and adherence to best practices. This command provides senior-level analysis with actionable recommendations.

Perform a thorough, senior-level code review focusing on design, maintainability, performance, security, and best practices. Provides constructive feedback with specific suggestions for improvement.

Create a comprehensive, risk-mitigated strategy for refactoring legacy code or large-scale architectural changes. This command helps plan refactoring that can be done incrementally without breaking production systems.

Design a robust, scalable system from scratch or plan major architectural changes. This command guides you through senior-level system design considerations including requirements, architecture, scalability, reliability, and tradeoffs.

Conduct a comprehensive audit of technical debt across your codebase, prioritizing issues and creating a roadmap for addressing accumulated debt. This command helps identify, quantify, and prioritize technical debt for systematic reduction.

You are an expert senior software developer with 10+ years of experience across multiple domains, technologies, and scales. You provide thoughtful, pragmatic technical guidance that balances best practices with real-world constraints. Your expertise spans architecture, system design, code quality, performance, security, and team leadership.

Scaffold and setup Chrome MV3 extensions using WXT framework with React, TypeScript, and shadcn-UI. Use when creating new browser extensions, setting up content scripts, background service workers, side panels, popups, or configuring native messaging. Supports Google Docs/Overleaf integrations, DOM extraction, and cross-context communication patterns.

Generate AI-friendly Python CLIs using Click, Pydantic, and uv. Use when user wants to create a new CLI tool that follows best practices for agentic coding environments.

Detect common code smells and anti-patterns providing feedback on quality issues a senior developer would catch during review. Use when user opens/views code files, asks for code review or quality assessment, mentions code quality/refactoring/improvements, when files contain code smell patterns, or during code review discussions.

Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).

Generate production-ready monorepo structures for full-stack applications including frontends (Next.js, React), APIs (Hono, Express), and data pipelines. Use when creating new monorepo projects, scaffolding multi-project architectures (web apps, APIs, workers, CLI tools), setting up shared packages, or configuring workspace tooling with Bun, PNPM, or Yarn.

Identify security vulnerabilities and anti-patterns providing feedback on security issues a senior developer would catch. Use when user mentions security/vulnerability/safety concerns, code involves user input/authentication/data access, working with sensitive data (passwords/PII/financial), code includes SQL queries/file operations/external API calls, user asks about security best practices, or security-sensitive files are being modified (auth, payment, data access).

Identify performance issues and bottlenecks suggesting optimizations a senior developer would recommend. Use when user mentions performance/optimization/speed issues, asks "why is this slow?" or similar questions, code contains obvious performance anti-patterns (N+1 queries, unnecessary loops, etc.), user works on performance-critical code paths, performance profiling shows bottlenecks, or large data processing or database operations detected.

Comprehensive guide for creating VS Code extensions from scratch, including project scaffolding, API usage, activation events, and packaging. Use when user wants to create/build/generate/develop a VS Code extension or plugin, asks about VS Code extension development, needs help with VS Code Extension API, discusses extension architecture, wants to add commands/webviews/language support, or mentions scaffolding a VS Code project.
