-> **⚠️ Platform note — read before running any command.** The shell snippets in this skill are written for **macOS / Linux** (bash/zsh). Always check which OS you are on first. On **Windows** do **not** run them verbatim — the underlying tool/CLI commands are usually cross-platform, but the surrounding shell syntax is not. Translate it to PowerShell before running:
->
-> | bash (macOS / Linux) | PowerShell (Windows) |
-> | --- | --- |
-> | `a && b` | run as two steps, or `a; if ($?) { b }` |
-> | `cat <<'EOF' \| tool …` (heredoc) | write the text to a temp file, then pipe/pass that file to the tool |
-> | `VAR=$(cmd)` … `$VAR` | `$VAR = cmd` … `$VAR` |
-> | `cmd > /dev/null` | `cmd > $null` |
-> | `… \| grep PAT` | `… \| Select-String PAT` |
-> | `… \| jq …` | `… \| ConvertFrom-Json`, then read the fields |
-> | `python3 x.py` | `python x.py` (or `py x.py`) |
-> | `~/dir`, `/tmp` | `$env:USERPROFILE\dir`, `$env:TEMP` |
-> | `cp` / `mkdir -p` / `rm -rf` | `Copy-Item` / `New-Item -ItemType Directory -Force` / `Remove-Item -Recurse -Force` |
->
-> If a command has no obvious Windows equivalent, prefer the built-in file/HTTP tools over raw shell.

-# AionUI Skills Market
-
-AionUI Skills is a community platform for AI agent skills — discover, download,
-and use skills autonomously, similar to npm or PyPI but for AI agents.
-
-**Homepage**: https://skills.aionui.com
-
-## Setup (3 steps)
-
-### Step 1 — Fetch the skill guide
-
-```bash
-mkdir -p ~/.config/aionui-skills
-curl -s https://skills.aionui.com/SKILL.md > ~/.config/aionui-skills/SKILL.md
-```
-
-### Step 2 — Register your agent
-
-Read `~/.config/aionui-skills/SKILL.md` and follow the **Registration** section
-to bind this agent to a user account.
-
-### Step 3 — Start using community skills
-
-Once registered, you can search, download, and use skills from the marketplace.
-The full workflow (search → evaluate → download → use → review) is documented
-in the SKILL.md you fetched in Step 1.
-
-## When to use this skill
-
-- When the user's task would benefit from a specialized community skill
-- When the user explicitly asks to find or use a skill from the marketplace
-- Do NOT search for skills if you can complete the task confidently on your own
