A skill is a set of instructions packaged as a SKILL.md file that an AI agent reads to learn a new workflow.
> Quick Answer: The fastest way to install is the one-liner curl command: mkdir -p ~/.claude/skills && curl -sL https://www.agensi.io/api/install/. This creates the directory, fetches the skill, and unpacks it. You can also download the ZIP from the skill's page on agensi.io and unzip into ~/.claude/skills/SKILL_NAME/ (personal) or .claude/skills/SKILL_NAME/ (project-scoped). Restart Claude Code, then run /skills to confirm it loaded.
Claude Code becomes a lot more useful once you start adding skills to it. Skills are packaged instructions that teach Claude Code, OpenClaw, and other AI agents how to handle specific tasks, from writing commit messages to reviewing code to generating documentation. The good news is that installing them takes less than a minute.
There are several ways to add skills to Claude Code. This guide walks through each method with step-by-step instructions so you can pick whichever fits your workflow.
Use the one-liner curl install command. From any agensi.io skill page, copy the slug and run:
mkdir -p ~/.claude/skills && curl -sL https://www.agensi.io/api/install/<slug> | tar xz -C ~/.claude/skills/
The command creates ~/.claude/skills/ if it doesn't exist, downloads the archive over HTTPS, and unpacks it in place. Restart Claude Code and run /skills to confirm.
On Windows PowerShell:
New-Item -ItemType Directory -Force -Path "$HOME\.claude\skills" | Out-Null
irm https://www.agensi.io/api/install/<slug> -OutFile skill.tar.gz; tar -xzf skill.tar.gz -C "$HOME\.claude\skills"; del skill.tar.gz
Free skills install directly. Paid skills require purchase - use the download button on the skill page after buying.
Make sure Claude Code is installed and working. Open your terminal and run:
claude --version
If you get a version number back, you're good. If not, install Claude Code first by following the instructions at claude.ai/install.
Skills are stored in two places:
~/.claude/skills/ and are available across all your projects.claude/skills/ inside a specific repo and are shared with anyone who clones itClaude Code has a built-in plugin system that lets you browse, install, and manage skills without leaving your terminal. This is the fastest method if the skill you want is available as a plugin.
Step 1. Start a Claude Code session in any project:
claude
Step 2. Type /plugin and press Enter. This opens the plugin browser.
Step 3. Navigate to the Discover tab. You'll see a list of available plugins from the default Anthropic marketplace.
Step 4. Find the plugin you want and press Enter to install it. Claude will ask you to choose a scope:
~/.claude/skills/).claude/skills/)/skill-name or let Claude load it automatically when it's relevant.
The default marketplace only has Anthropic's official plugins. To access community skills, add a third-party marketplace:
/plugin marketplace add author/repository
For example, to add a popular community skills collection:
/plugin marketplace add alirezarezvani/claude-skills
After adding a marketplace, its plugins show up in the Discover tab alongside the official ones.
If a skill isn't available as a plugin, or if you prefer to manage files yourself, you can install skills by copying them into the right directory. This works for skills downloaded as zip files, cloned from GitHub, or created by hand.
Step 1. Download the skill zip file. On Agensi, click the download button on any skill page.
Step 2. Unzip it into your skills directory:
# Personal install (all projects)
unzip code-reviewer.zip -d ~/.claude/skills/
Project install (current repo only)
unzip code-reviewer.zip -d .claude/skills/
Step 3. Verify the folder structure looks right:
ls ~/.claude/skills/code-reviewer/
You should see at least a SKILL.md file. Some skills also include scripts/, references/, or assets/ folders.
Step 4. Start a new Claude Code session. Claude will automatically detect the new skill.
Step 1. Clone the repository:
git clone https://github.com/author/skill-name.git
Step 2. Copy the skill folder (not the whole repo) to your skills directory:
cp -r skill-name ~/.claude/skills/skill-name
If the repo contains multiple skills in subdirectories, copy just the one you want:
cp -r repo-name/skills/code-reviewer ~/.claude/skills/code-reviewer
Step 3. Start a new session and the skill will be available.
After installing any skill, you can check that Claude recognizes it. Start a session and type:
/skill-name
If the skill loads, you'll see Claude acknowledge it and follow the skill's instructions. If nothing happens, double check that the SKILL.md file is in the right location and that the folder is directly inside ~/.claude/skills/ (not nested an extra level deep).
Agensi is a marketplace for curated, security-reviewed SKILL.md skills. Every skill goes through an automated 8-point security scan before it goes live, so you know what you're installing has been inspected.
Step 1. Browse skills at agensi.io/skills. Filter by category, price, or popularity.
Step 2. Click on a skill to see its detail page. Check the description, tags, and security scan results.
Step 3. Click Download (for free skills) or Buy (for paid skills). You'll get a zip file.
Step 4. Unzip into your Claude Code skills directory:
unzip skill-name.zip -d ~/.claude/skills/
Step 5. Start a new Claude Code session. Done.
Agensi skills work with Claude Code out of the box, but most are also compatible with Codex CLI, Cursor, Gemini CLI, and other agents that support the SKILL.md format. Check the compatibility info on each skill's page.
Over time you'll accumulate skills. Here are a few useful things to know:
List all installed skills:
ls ~/.claude/skills/
Remove a skill: Just delete its folder.
rm -rf ~/.claude/skills/skill-name
Update a skill: Replace the folder with the new version. If you bought it on Agensi, download the latest version from your dashboard. For GitHub skills, pull the latest changes.
Disable a skill temporarily: Rename the folder to something Claude won't recognize, like adding an underscore prefix:
mv ~/.claude/skills/code-reviewer ~/.claude/skills/_code-reviewer
Rename it back to re-enable.
If you're just getting started, here are a few skills that most developers find useful right away:
For terminal-first installs, three patterns cover most cases:
# Direct from Agensi (copy ZIP URL from the skill page)
curl -L <ZIP_URL> -o skill.zip && unzip skill.zip -d ~/.claude/skills/ && rm skill.zip
From GitHub
git clone https://github.com/author/skill-name.git ~/.claude/skills/skill-name
Batch from a directory of zips
for zip in ~/downloads/skills/*.zip; do unzip "$zip" -d ~/.claude/skills/; done
The same skill folder works in OpenClaw and Codex CLI. Symlink for a single source of truth:
ln -s ~/.claude/skills ~/.openclaw/skills
ln -s ~/.claude/skills ~/.codex/skills
ls ~/.claude/skills/ # list installed
rm -rf ~/.claude/skills/skill-name # remove
mv ~/.claude/skills/foo ~/.claude/skills/_foo # disable (rename out)
tar -czf ~/skills-backup.tar.gz ~/.claude/skills/ # backup
