Claude-Code-Everything-You-Need-to-Know

Audit a CLAUDE.md file for the patterns that actually degrade Claude Code's output — vagueness, unnamed files, stale facts, and bloat. Use when asked to review, audit, improve, shrink, or fix a CLAUDE.md, and when a project's results feel inconsistent or Claude keeps rediscovering the same context.

Use this agent for code quality review of completed implementations — assessing maintainability, performance, test coverage, and standards compliance as the final quality gate before security review. For example: reviewing a finished frontend/backend feature and producing prioritized findings (Blocker/High-Priority/Medium/Nitpick) with actionable fixes.

Apply the Five Whys root cause analysis technique to investigate an issue

Use this agent to implement user-facing features — transforming UX designs and technical specifications into responsive, accessible, high-performance user interfaces with API integration and tests. Delegate frontend build work such as UI components, styling, client-side state and data handling, or web performance optimization.

Create a branch, split changes into logical commits, and open a pull request

Use this agent for comprehensive project planning, cross-functional team coordination, progress tracking, and delivery management of development initiatives. For example: planning a 6-week user authentication project across a UX designer, backend developer, and QA tester, or regaining control of a project facing delays and scope creep.

Run a multi-perspective PR review (product, dev, QA, security, DevOps, UX) and post it to GitHub

Development practices and TDD workflow to follow before starting a feature

Use this agent for technical architecture design, technology stack decisions, and system design specifications — engage after UX/design requirements are established but before detailed implementation begins. For example: planning the architecture for an event management dashboard from completed UX designs, choosing the stack and patterns for a new microservices project, or recommending scaling strategies for performance issues under load.

User Experience Designer & UI Specialist persona for design-focused tasks

Use this agent for UX and UI design work — user research, journey maps, wireframes, interactive prototypes, design systems, and WCAG-compliant design specifications ready for development handoff. Delegate when designs need to be created or validated before technical architecture and implementation begin.
