Systematic debugging methods, log analysis, and performance diagnostics. Use when debugging issues, analyzing errors, or troubleshooting incidents.

Simplifies code architecture post-feature completion to enhance maintainability and eliminate redundancy.

Optimize database design, query performance, and manage migrations effectively.

Analyzes task complexity, creates implementation plans, and breaks down into minimal executable units. Use PROACTIVELY when users request feature implementation, architectural changes, or complex refactoring. Automatically activated for planning tasks. <example> user: "实现用户权限管理模块" assistant: (invokes planner agent to analyze complexity and create implementation plan) </example>

Performs deep code review checking architecture compliance, code quality, and security issues. Use PROACTIVELY after writing or modifying code. MUST BE USED for all significant code changes. <example> user: "审查这次提交的代码变更" assistant: (invokes code-reviewer agent to perform comprehensive code review) </example>

Cross-validate code, architecture or design decisions using a second model. Use for critical decisions, complex refactoring, security reviews.

Manage session lifecycles effectively with strategies for learning and context compression.

Testing strategies and methodologies including TDD and E2E testing. Use when writing tests, implementing TDD workflow, or setting up E2E test infrastructure.

System architecture specialist for design decisions, ADR creation, and scalability assessment. Use PROACTIVELY when designing new systems, making architectural decisions, or evaluating technical approaches. <example> user: "我们需要设计一个支持高并发的订单系统" assistant: (invokes architect agent to analyze requirements and design system architecture) </example>

Extracts reusable patterns from development sessions to enhance continuous learning.

RESTful API design patterns and best practices. Use when creating endpoints, designing APIs, or implementing routes.

Checks code for security vulnerabilities including OWASP Top 10, secret leaks, and injection attacks. Use PROACTIVELY before commits when working with authentication, user input, secrets, or API endpoints. Critical for security-sensitive changes. <example> user: "检查登录模块的安全性" assistant: (invokes security-reviewer agent to scan for OWASP vulnerabilities and secret leaks) </example>

Code quality assurance strategies. Parent skill for quality-related skills: security (security review) and debug (systematic debugging).

Security review skill: comprehensive security checklist and patterns. Use when adding authentication, handling user input, working with secrets, or creating API endpoints.

Facilitates model selection and routing for various task types to optimize performance and cost.

Validates the quality of requirement documents through completeness, clarity, and consistency checks.

CC-Best streamlines development workflows for Claude Code with role-driven automation.

Best practices for backend development, including error handling, logging, and caching.

Guides test-driven development, helps write test cases, and ensures code quality. Use PROACTIVELY when writing new features, fixing bugs, or refactoring code. Ensures 80%+ test coverage with write-tests-first methodology. <example> user: "用 TDD 方式实现购物车功能" assistant: (invokes tdd-guide agent to write failing tests first, then implement code) </example>

Research-before-coding workflow: systematically search existing solutions before custom implementation. Use when introducing new libraries, tools, or solving unfamiliar problems.

Master Git version control with best practices for branching, commits, and merging.

Strategies for native app development on iOS/macOS and Tauri desktop apps.

Strategically compress context at logical breakpoints to enhance session efficiency.
