+# agentskill.sh — Skill Discovery & Installation
+
+Browse, install, and manage 110,000+ AI agent skills from [agentskill.sh](https://agentskill.sh), the cross-platform skills registry.
+
+## Setup (First Use)
+
+This is a lightweight loader. On first use, fetch the full `/learn` skill for the complete experience:
+
+```bash
+# Use the add-skill extension to fetch the latest version from GitHub
+python3 .agents/skills/add-skill/scripts/fetch_skill.py "https://github.com/agentskill-sh/learn" "$(pwd)"
+```
+
+If `add-skill` is not available, fetch manually:
+
+```bash
+mkdir -p .agents/skills/learn
+curl -sL "https://raw.githubusercontent.com/agentskill-sh/learn/main/SKILL.md" -o .agents/skills/learn/SKILL.md
+```
+
+After installation, the full `/learn` skill handles everything below automatically with richer features including security scanning, auto-updates, and feedback.
+
+## Quick Start (Without Full Install)
+
+### Search for skills
+
+Use WebFetch to query:
+```
+GET https://agentskill.sh/api/agent/search?q=<query>
+```
+
+Returns JSON with matching skills: name, description, owner, slug, install count.
+
+### Install a specific skill
+
+```
+GET https://agentskill.sh/api/agent/skills/<owner>/<slug>/install
+```
+
+Returns the skill content. Write it to `.agents/skills/<slug>/SKILL.md`.
+
+### Browse trending skills
+
+```
+GET https://agentskill.sh/api/agent/search?section=trending
+```
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `/learn <query>` | Search skills by keyword |
+| `/learn @owner/slug` | Install a specific skill |
+| `/learn trending` | Show trending skills |
+| `/learn list` | Show installed skills |
+| `/learn update` | Check for skill updates |
