Agent Skills
A suite of 24 engineering skills and eight lifecycle commands for AI coding agents, covering specification, planning, implementation, testing, review, and shipping.
Project overview
Agent Skills is a Agent Skill built around a suite of 24 engineering skills and eight lifecycle commands for AI coding agents, covering specification, planning, implementation, testing, review, and shipping. Its value is practical: full development lifecycle and test-driven development are available from one documented project, while the repository remains inspectable before it is added to an agent workflow.
Core capabilities
Full development lifecycle
Full development lifecycle is documented in the repository README or its component instructions. Review the linked source for current behavior and requirements.
Test-driven development
Test-driven development is documented in the repository README or its component instructions. Review the linked source for current behavior and requirements.
Code review and simplification
Code review and simplification is documented in the repository README or its component instructions. Review the linked source for current behavior and requirements.
Web performance audits
Web performance audits is documented in the repository README or its component instructions. Review the linked source for current behavior and requirements.
Installation and usage
Set up Agent Skills from its public GitHub instructions, keep the initial permission scope small, and verify it with a low-risk task before regular use.
Let an AI Agent install it
Send this prompt to Codex, Claude Code, or another AI agent that can work with your local environment.

Read the repository README and license first. Confirm the current host, prerequisites, destination paths, and permissions. Follow the repository's documented method, keep credentials out of files and logs, and start with the least-privilege or read-only option where available. Afterward, run a small verification and report the exact changes, commands, configuration path, and result. Ask before overwriting files or requesting broader access.- Node.js and npx are installed
- The current agent's Skills directory is writable
npx skills add addyosmani/agent-skills- 1Review prerequisites and scope
Read the README, confirm the target host, and prepare these prerequisites: Node.js and npx are installed; The current agent's Skills directory is writable. Check destination paths and permissions before making changes.
- 2Apply the documented setup
Run the documented command: npx skills add addyosmani/agent-skills
- 3Verify with a small task
Restart or reload the target agent, confirm that Agent Skills appears in its installed extensions or skills, and run the smallest documented example before using it on important work.
Restart or reload the target agent, confirm that Agent Skills appears in its installed extensions or skills, and run the smallest documented example before using it on important work.
- Installing the full suite adds context and maintenance overhead
- Per-skill installation does not include repository-level references
Use cases
Software work from specification to shipping
Software work from specification to shipping is a practical fit when the repository's documented prerequisites and permission model match the current environment.
Shared code-review practices for a team
Shared code-review practices for a team is a practical fit when the repository's documented prerequisites and permission model match the current environment.
Adding tests and quality gates to an existing project
Adding tests and quality gates to an existing project is a practical fit when the repository's documented prerequisites and permission model match the current environment.
Assessment
This assessment is based on the repository README, component documentation, license, and maintenance metadata. Covers the development lifecycle with a clear split between commands and skills; Lets users inspect the catalog and install only the skills they need. The main trade-offs are also clear: Installing the full suite adds context and maintenance overhead; Per-skill installation does not include repository-level references. No local installation or functional test was claimed during cataloging.
Why it may be useful
- Covers the development lifecycle with a clear split between commands and skills
- Lets users inspect the catalog and install only the skills they need
What to know first
- Installing the full suite adds context and maintenance overhead
- Per-skill installation does not include repository-level references

Getting started
- Set up Agent Skills from its public GitHub instructions, keep the initial permission scope small, and verify it with a low-risk task before regular use.
- The repository describes Agent Skills as a suite of 24 engineering skills and eight lifecycle commands for AI coding agents, covering specification, planning, implementation, testing, review, and shipping.
- Its main capabilities include full development lifecycle, test-driven development, code review and simplification, web performance audits. The documented facts include 24 engineering skills, eight lifecycle commands, individual skill installation, support through the skills cli for 70+ agents.
- Restart or reload the target agent, confirm that Agent Skills appears in its installed extensions or skills, and run the smallest documented example before using it on important work.
