1. Software Development

Compares current branch changes against main branch to evaluate design, maintainability, and correctness for code quality assurance.

Analyzes fuzzing test coverage to identify uncovered code, magic values, and measure campaign effectiveness.

Fetches LLM-optimized API documentation from designated endpoints to provide developers with up-to-date reference materials.

Applies Lean Manufacturing principles (5 Whys, Ishikawa, PDCA) to software development tasks like bug analysis and code review for systematic problem solving.

Automates final branch completion: verifies tests, presents merge/PR options, and cleans worktree for efficient development cycles.

Offers 100+ performance optimization rules for Three.js, covering memory, rendering, geometry, materials, WebGPU, and WebXR.

Enforces test-driven development: write tests first, watch them fail, then implement minimal code to pass.

A structured four-phase debugging methodology: root cause investigation, pattern analysis, hypothesis testing, and implementation.

Builds stateful, coordinated applications on Cloudflare's edge using Durable Objects for persistent data management.

Offers best practices for optimizing React Native app performance including FPS, bundle size, TTI, memory management, and animations.

Enforces server-first rendering and proper client boundaries for React 19 and Next.js 16 App Router components, hooks, and pages.

Mandatory checklist enforcing DRY principle and existing pattern reuse before any new code implementation.

Dispatches multiple agents to independently solve problems across different domains concurrently in a single workflow.

Provides a guide for validating external data using Zod, covering API responses, webhooks, and user input to ensure data integrity.

Enforces TypeScript type organization by mandating all types, interfaces, and DTOs to reside in the /types directory, preventing inline type definitions.

Evaluates external code review suggestions against project-specific conventions to validate or reject comments.

Guides service worker caching updates by editing sw-template.js and executing yarn prebuild for seamless integration.

Guides bundle size and image optimization using Next.js Server Components and image quality caps for enhanced frontend performance.

Enforces URL canonicalization rules to prevent SEO issues and costly incidents from improper URL structures, especially avoiding searchParams on listing pages.

Provides testing patterns for unit and end-to-end tests using Vitest and Playwright, including SEO and sitemap validation.

Provides best practices for internationalization in Next.js using next-intl, including proper link usage with @i18n/routing.

Enforces a standardized internal API proxy layer pattern for adding endpoints, data fetching, and HMAC signing within lib/api/ and app/api/ directories.

Guides implementation and debugging of configuration-driven filters, including URL parsing and updates to the filters configuration file.

Performs comprehensive code reviews focusing on correctness, security, and LLM/MCP safety to ensure robust and secure code in repositories.
