README

Quick Start

Copy-paste this into your AI agent (Claude Code, Cursor, Copilot, Codex, Windsurf, Gemini CLI, etc.):

Run: npx @agentskill.sh/cli@latest setup
Then search for skills relevant to this project using /learn

That's it. Your agent will install /learn, analyze your project, and suggest relevant skills from a directory of 100,000+.

<details> <summary>Other install methods</summary>

Install globally (then use ags directly)

npm install -g @agentskill.sh/cli
ags setup

Plugin marketplace (Claude Code only)

/plugin marketplace add https://agentskill.sh/marketplace.json
/plugin install learn@agentskill-sh

Note: the plugin marketplace only installs the /learn skill. Use npx @agentskill.sh/cli setup to get all skills.

Why /learn and agentskill.sh?

Two-layer security. After incidents like OpenClaw showed how malicious skill files can compromise agents, vetting matters. agentskill.sh runs server-side static analysis on every skill across 12 threat categories:

Command injection, data exfiltration, credential harvesting, prompt injection, obfuscation, sensitive file access, persistence mechanisms, external calls, reverse shells, destructive commands, social engineering, supply chain attacks

Each skill gets a security score (0-100). 110,000+ skills scanned, 100% coverage. Skills scoring below 30 require explicit confirmation before installation. Then /learn performs a second client-side scan before writing any files, so you get both centralized scanning and local verification. See the live security dashboard.

Feedback loop. Agents auto-rate skills after use (1-5 scale with comments), so the best ones surface and broken ones get flagged by the community. Your agent contributes to, and benefits from, collective quality signals.
Version tracking. Every installed skill is tagged with a content SHA, so you always know exactly what version you're running. When a newer version is available, /learn update shows what changed. Nothing breaks silently.
Search broadly. Instead of hunting for skills manually, search 100,000+ skills mid-conversation. Find what you need, install it, keep working.

What is this?

This repo contains the official CLI and skills for agentskill.sh.

| What | Description | |------|-------------| | ags CLI | Terminal tool to search, install, list, update, remove, and rate skills. Published to npm as @agentskill.sh/cli. | | /learn skill | Agent skill that gives your AI the same capabilities mid-conversation. Uses the CLI under the hood. | | review-skill skill | Reviews SKILL.md files against best practices and scores them on 10 quality dimensions. |

CLI Commands

ags search <query>              # Search 100,000+ skills
ags install <slug>              # Install a skill
ags install @owner/skill-name   # Install from specific author
ags list                        # Show installed skills
ags update                      # Check for and apply updates
ags remove <slug>               # Uninstall a skill
ags feedback <slug> <1-5> [msg] # Rate a skill

All commands support --json for structured output.

/learn Commands

When using the skill inside your agent:

| Command | What it does | |---------|--------------| | /learn <query> | Search for skills, interactive install | | /learn @owner/slug | Install a specific skill | | /learn skillset:<slug> | Install a curated bundle | | /learn | Context-aware recommendations based on your project | | /learn trending | Show trending skills | | /learn list | Show installed skills | | /learn update | Check for updates | | /learn remove <slug> | Uninstall a skill | | /learn feedback <slug> <1-5> | Rate a skill |

Examples

# Find SEO skills
ags search "programmatic seo"

# Install a specific skill from an author
ags install @anthropics/react-best-practices

# Install for Cursor instead of Claude Code
ags install seo-optimizer --platform cursor

# Rate a skill you used
ags feedback seo-optimizer 5 "Excellent keyword clustering"

# Update all installed skills
ags update

# List installed skills as JSON
ags list --json

How It Works

Search queries the agentskill.sh API
Install writes the skill to your platform's skill directory (e.g., .claude/skills/)
Metadata header is injected for version tracking and auto-review
Auto-review: after using a skill, your agent rates it automatically (1-5 scale)
Update compares local content hashes against the registry and re-installs outdated skills

Supported Platforms

The CLI auto-detects your platform. Override with --platform <name>.

| Platform | Skill directory | Flag | |----------|----------------|------| | Claude Code | .claude/skills/ | claude-code | | Cursor | .cursor/skills/ | cursor | | GitHub Copilot | .github/copilot/skills/ | copilot | | Codex | .codex/skills/ | codex | | Windsurf | .windsurf/skills/ | windsurf | | Gemini CLI | .gemini/skills/ | gemini-cli | | Amp | .amp/skills/ | amp | | Goose | .goose/skills/ | goose | | Aider | .aider/skills/ | aider | | Cline | .cline/skills/ | cline | | Roo Code | .roo-code/skills/ | roo-code | | Trae | .trae/skills/ | trae | | Hermes | ~/.hermes/skills/ | hermes | | OpenCode | .opencode/skills/ | opencode | | ChatGPT | .chatgpt/skills/ | chatgpt |

Security

Every skill on agentskill.sh has a security score (0-100). Skills below 30 trigger a warning before installation.

The /learn skill includes a security pattern library for detecting prompt injection, data exfiltration, obfuscated code, and other threats.
