Getting started
What is Jeffrey's Skills.md?
Jeffrey's Skills.md is a premium subscription service for AI agent skills - curated markdown instruction files that give your AI agent (Claude Code, Claude Desktop, ChatGPT, Codex, Cursor and others) new capabilities like code review, test generation, database migration, and more.
For $20/month you get:
- Access to a growing catalog of premium skills
- The
jsmCLI for offline-first skill management - Automatic skill updates and version pinning
- Community support and skill requests
How skills work
A skill is a folder with a SKILL.md file that your agent loads from its skills
directory: ~/.claude/skills/ for Claude Code and Claude Desktop,
~/.agents/skills/ for Codex and ChatGPT, and similar folders for other agents.
Skills contain instructions, patterns, and domain knowledge that shape how your
agent responds.
~/.claude/skills/
code-review-expert/
SKILL.md # The skill instructions
examples/ # Optional usage examples
When you ask your agent for help, it reads the installed skills that fit the task and applies their guidance to your conversation.
