帮助生成规范的 Git 提交信息，遵循 Conventional Commits 规范

Design and implement effective test automation with proper pyramid, patterns, and CI/CD integration. Use when building automation frameworks or improving test efficiency.

Provides expert guidance on Git operations including branch management, commit best practices, merge conflicts, and version control workflows. Use when the user needs help with Git commands, workflows, or resolving repository issues.

Searching internet for technical documentation using llms.txt standard, GitHub repositories via Repomix, and parallel exploration. Use when user needs: (1) Latest documentation for libraries/frameworks, (2) Documentation in llms.txt format, (3) GitHub repository analysis, (4) Documentation without direct llms.txt support, (5) Multiple documentation sources in parallel

Use when you need to run interactive CLI tools (vim, git rebase -i, Python REPL, etc.) that require real-time input/output - provides tmux-based approach for controlling interactive sessions through detached sessions and send-keys

Generate high-quality conventional git commit messages and, with user approval, run the commit. Use when drafting or refining commit messages, validating commit quality, or committing staged work while avoiding noisy histories.

Run the project's formatter, linters, and mypy checks in the required order, fixing issues and managing any needed stub dependencies via uv.

Intelligent skill router that analyzes user requests and automatically dispatches to the most appropriate skill(s) or zen-mcp tools. Routes to zen-chat for Q&A, zen-thinkdeep for deep problem investigation, codex-code-reviewer for code quality, simple-gemini for standard docs/tests, deep-gemini for deep analysis, or plan-down for planning. Use this skill proactively to interpret all user requests and determine the optimal execution path.

Systematic code review workflow using zen mcp's codex tool. Use this skill when the user explicitly requests "use codex to check the code", "check if the recently generated code has any issues", or "check the code after each generation". The skill performs iterative review cycles - checking code quality, presenting issues to the user for approval, applying fixes, and re-checking until no issues remain or maximum iterations (5) are reached.

Use when you need direct browser control - teaches Chrome DevTools Protocol for controlling existing browser sessions, multi-tab management, form automation, and content extraction via use_browser MCP tool

Analyzes code quality, complexity, and technical debt using PMAT(Pragmatic AI Labs MCP Agent Toolkit). Use this skill when:- User mentions "code quality", "complexity", "technical debt", or "maintainability"- Reviewing code or conducting code review- Modifying or refactoring existing code files- Creating pull requests or preparing commits- Investigating performance or quality issuesSupports 25+ languages including Rust, Python, TypeScript, JavaScript, Go, C++, Java, Ruby, PHP, Swift, and more.Provides cyclomatic complexity, cognitive complexity, maintainability index, dead code detection,and technical debt annotations (SATD: TODO, FIXME, HACK comments).

Generates comprehensive, LLM-optimized codebase context using PMAT(Pragmatic AI Labs MCP Agent Toolkit). Use this skill when:- Starting work on unfamiliar codebases- Onboarding to new projects or repositories- Need quick understanding of project architecture- Preparing for refactoring or feature implementation- Creating documentation or technical specificationsOutputs highly compressed markdown (60-80% reduction) optimized for LLM consumption.Supports 25+ languages with architecture visualization, complexity heatmaps, and dependency graphs.
