skills
Skills is a domain-agnostic library of AI agent skills for building autonomous software workflows. Created by dzhng, it provides composable building blocks that enable AI coding assistants to break down complex features into independently verifiable pieces, iteratively build and review code, and pursue goals autonomously until output meets quality standards. The skills work with any harness supporting the skills format, including Claude Code, Codex, Cursor, and 70+ other AI development tools. Each skill can be used individually for ad hoc tasks or chained together into full automated pipelines for end-to-end feature development.
Key Features
Use Cases
- 01Autonomous feature development: map unknowns, generate specs, implement code, and review choices over multi-day unattended runs
- 02Breaking down large features into independently verifiable slices with API seams and testable checkpoints
- 03Ad hoc code refactoring and review when changes grow beyond expected scope
- 04Visual regression testing and UI validation through screenshot comparison and critique workflows
- 05Parallel delegation of independent work slices to multiple AI coding agents
- 06Maintaining living specifications that update mid-implementation when code reveals stale planning

skills — FAQ
What are dzhng/skills and what do they do?+
Skills is a personal library of domain-agnostic agent skills that extend AI coding assistants with capabilities for autonomous software development. The skills enable AI agents to explore requirements, write specifications, implement features iteratively, conduct code reviews, and verify outputs until they meet quality standards.
How do I install skills for my AI coding assistant?+
Run 'npx skills add dzhng/skills' to install all skills, or add '--list' to select individual ones. Alternatively, copy any 'skills/<category>/<name>/' folder directly into your harness's skills directory (for example, '.claude/skills/').
Which AI clients and harnesses work with these skills?+
These skills work with any harness supporting the skills format, including Claude Code, Codex, opencode, Cursor, duet, and over 70 other AI development tools.
Do I need API keys or prerequisites to use these skills?+
You need an AI coding assistant or harness that supports the skills format. Some skills like 'codex' and 'claude' require those respective tools installed locally to delegate work to independent AI agents.
Is skills free to use?+
Yes, skills is open source and released under the MIT license, making it free to use, modify, and distribute.
How do I use skills for autonomous multi-day feature development?+
Run '/explore-unknowns' to map requirements, '/write-spec' to create the implementation plan, then '/goal /implement-spec specs/<feature>' to start the autonomous build loop. The AI will iteratively build, review, and verify until the feature is complete, consolidating decisions in a 'choices.md' file for your final review.
How do I install skills?+
Open the source repository on GitHub and follow its README. skills is a skill — MCP Agents Market links you directly to the official repo.
