Skills

A collection of Agent Skills — reusable, portable capabilities for AI coding agents like Claude Code, Cursor, Codex, and others.

What is a Skill?

A skill is a folder containing a SKILL.md file (YAML frontmatter + instructions), plus optional scripts, references, and assets. Agents load skills on demand, giving them domain-specific expertise without bloating context.

skill-name/
├── SKILL.md # required: name, description, instructions
├── scripts/ # optional: executable code
├── references/ # optional: docs
└── assets/ # optional: templates, resources

Origin and standard

Skills originated at Anthropic as an internal mechanism for Claude Code, then were published as an open standard (Apache 2.0 / CC-BY-4.0) at agentskills.io in December 2025. The format is now supported natively across Claude Code, Codex CLI, Gemini CLI, GitHub Copilot, Cursor, and more.

For the full spec, see agentskills.io/specification.

Using a Skill

Once installed, you don't invoke a skill directly — just describe what you want, and the agent decides whether to load it based on its description. For example, if you have the pdf skill installed, asking "extract the text from this PDF" is enough to trigger it.

All commands below use the skills CLI (npx skills), which supports Claude Code, Cursor, Codex, and 60+ other agents.

Install

# Interactive — pick which skill(s) and agent(s) to install
npx skills add udohjeremiah/skills

# List all skills in this repo without installing
npx skills add udohjeremiah/skills --list

# Install a specific skill
npx skills add udohjeremiah/skills --skill <skill-name>

# Install multiple specific skills
npx skills add udohjeremiah/skills --skill <skill-a> --skill <skill-b>

# Install all skills in this repo
npx skills add udohjeremiah/skills --all

# Install to a specific agent (e.g. claude-code, cursor, codex)
npx skills add udohjeremiah/skills --skill <skill-name> -a claude-code

# Install globally (available across all your projects, not just this one)
npx skills add udohjeremiah/skills --skill <skill-name> -g

# Non-interactive install (skip prompts, e.g. for CI/CD)
npx skills add udohjeremiah/skills --skill <skill-name> -y

Use without installing

Generate a prompt for a skill, or run it directly through a supported agent.

# Interactive — pick the skill and agent
npx skills use udohjeremiah/skills

# Print the generated prompt to stdout
npx skills use udohjeremiah/skills --skill <skill-name>

# Pipe straight into an agent
npx skills use udohjeremiah/skills@<skill-name> | claude

# Start a specific agent interactively with the skill loaded
npx skills use udohjeremiah/skills --skill <skill-name> --agent claude-code

List installed skills

# List all installed skills (project + global)
npx skills list

# List only global skills
npx skills list -g

# Filter by agent
npx skills list -a claude-code -a cursor

Update

# Update all installed skills (interactive scope prompt)
npx skills update

# Update a specific skill
npx skills update <skill-name>

# Update multiple specific skills
npx skills update <skill-a> <skill-b>

# Update only global or only project skills
npx skills update -g
npx skills update -p

# Non-interactive update
npx skills update -y

Remove

# Interactive — pick which installed skill(s) to remove
npx skills remove

# Remove a specific skill
npx skills remove <skill-name>

# Remove multiple skills
npx skills remove <skill-a> <skill-b>

# Remove from global scope
npx skills remove --global <skill-name>

# Remove from a specific agent only
npx skills remove --agent claude-code <skill-name>

# Remove all skills from a specific agent
npx skills remove --skill '*' -a cursor

# Remove all installed skills without confirmation
npx skills remove --all
