Auto-register skills from plugin, simplify OpenCode install to one line

The plugin's new `config` hook injects the skills directory into
OpenCode's live config singleton, so skills are discovered automatically
without symlinks or manual config edits.

Installation is now just adding one line to opencode.json:
  "plugin": ["superpowers@git+https://github.com/obra/superpowers.git"]

Rewrote docs/README.opencode.md and .opencode/INSTALL.md to reflect
the new approach, removing ~200 lines of platform-specific symlink
instructions. Added migration notes for existing users.

 ## Prerequisites
 
 - [OpenCode.ai](https://opencode.ai) installed
-- Git installed
 
-## Installation Steps
+## Installation
 
-### 1. Clone Superpowers
+Add superpowers to the `plugin` array in your `opencode.json` (global or project-level):
 
-```bash
-git clone https://github.com/obra/superpowers.git ~/.config/opencode/superpowers
+```json
+{
+  "plugin": ["superpowers@git+https://github.com/obra/superpowers.git"]
+}
 ```
 
-### 2. Register the Plugin
+Restart OpenCode. That's it — the plugin auto-installs and registers all skills.
 
-Create a symlink so OpenCode discovers the plugin:
+Verify by asking: "Tell me about your superpowers"
 
-```bash
-mkdir -p ~/.config/opencode/plugins
-rm -f ~/.config/opencode/plugins/superpowers.js
-ln -s ~/.config/opencode/superpowers/.opencode/plugins/superpowers.js ~/.config/opencode/plugins/superpowers.js
-```
+## Migrating from the old symlink-based install
 
-### 3. Symlink Skills
-
-Create a symlink so OpenCode's native skill tool discovers superpowers skills:
+If you previously installed superpowers using `git clone` and symlinks, remove the old setup:
 
 ```bash
-mkdir -p ~/.config/opencode/skills
+# Remove old symlinks
+rm -f ~/.config/opencode/plugins/superpowers.js
 rm -rf ~/.config/opencode/skills/superpowers
-ln -s ~/.config/opencode/superpowers/skills ~/.config/opencode/skills/superpowers
-```
 
-### 4. Restart OpenCode
+# Optionally remove the cloned repo
+rm -rf ~/.config/opencode/superpowers
 
-Restart OpenCode. The plugin will automatically inject superpowers context.
+# Remove skills.paths from opencode.json if you added one for superpowers
+```
 
-Verify by asking: "do you have superpowers?"
+Then follow the installation steps above.
 
 ## Usage
 
-### Finding Skills

-```
-Clone https://github.com/obra/superpowers to ~/.config/opencode/superpowers, then create directory ~/.config/opencode/plugins, then symlink ~/.config/opencode/superpowers/.opencode/plugins/superpowers.js to ~/.config/opencode/plugins/superpowers.js, then symlink ~/.config/opencode/superpowers/skills to ~/.config/opencode/skills/superpowers, then restart opencode.
+```json
+{
+  "plugin": ["superpowers@git+https://github.com/obra/superpowers.git"]
+}
 ```
 
-## Manual Installation
+Restart OpenCode. The plugin auto-installs via Bun and registers all skills automatically.
 
-### Prerequisites
+Verify by asking: "Tell me about your superpowers"
 
-- [OpenCode.ai](https://opencode.ai) installed
-- Git installed
+### Migrating from the old symlink-based install
 
-### macOS / Linux
+If you previously installed superpowers using `git clone` and symlinks, remove the old setup:
 
 ```bash
-# 1. Install Superpowers (or update existing)
-if [ -d ~/.config/opencode/superpowers ]; then
-  cd ~/.config/opencode/superpowers && git pull
-else
-  git clone https://github.com/obra/superpowers.git ~/.config/opencode/superpowers
-fi
-
-# 2. Create directories
-mkdir -p ~/.config/opencode/plugins ~/.config/opencode/skills
-
-# 3. Remove old symlinks/directories if they exist
+# Remove old symlinks
 rm -f ~/.config/opencode/plugins/superpowers.js
 rm -rf ~/.config/opencode/skills/superpowers
 
-# 4. Create symlinks
-ln -s ~/.config/opencode/superpowers/.opencode/plugins/superpowers.js ~/.config/opencode/plugins/superpowers.js
-ln -s ~/.config/opencode/superpowers/skills ~/.config/opencode/skills/superpowers
-
-# 5. Restart OpenCode
-```
-
-#### Verify Installation
-
-```bash
-ls -l ~/.config/opencode/plugins/superpowers.js
-ls -l ~/.config/opencode/skills/superpowers
-```
-
-Both should show symlinks pointing to the superpowers directory.
-
-### Windows
-
-**Prerequisites:**
-- Git installed
-- Either **Developer Mode** enabled OR **Administrator privileges**
-  - Windows 10: Settings → Update & Security → For developers
-  - Windows 11: Settings → System → For developers
-
-Pick your shell below: [Command Prompt](#command-prompt) | [PowerShell](#powershell) | [Git Bash](#git-bash)
-
-#### Command Prompt
-
-Run as Administrator, or with Developer Mode enabled:
-
-```cmd
-:: 1. Install Superpowers
-git clone https://github.com/obra/superpowers.git "%USERPROFILE%\.config\opencode\superpowers"
-
-:: 2. Create directories
-mkdir "%USERPROFILE%\.config\opencode\plugins" 2>nul
-mkdir "%USERPROFILE%\.config\opencode\skills" 2>nul
-
-:: 3. Remove existing links (safe for reinstalls)
-del "%USERPROFILE%\.config\opencode\plugins\superpowers.js" 2>nul
-rmdir "%USERPROFILE%\.config\opencode\skills\superpowers" 2>nul
-
-:: 4. Create plugin symlink (requires Developer Mode or Admin)
-mklink "%USERPROFILE%\.config\opencode\plugins\superpowers.js" "%USERPROFILE%\.config\opencode\superpowers\.opencode\plugins\superpowers.js"
-
-:: 5. Create skills junction (works without special privileges)
-mklink /J "%USERPROFILE%\.config\opencode\skills\superpowers" "%USERPROFILE%\.config\opencode\superpowers\skills"
-
-:: 6. Restart OpenCode
-```
-
-#### PowerShell
-
-Run as Administrator, or with Developer Mode enabled:
-
-```powershell
-# 1. Install Superpowers
-git clone https://github.com/obra/superpowers.git "$env:USERPROFILE\.config\opencode\superpowers"
-
-# 2. Create directories
-New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.config\opencode\plugins"
-New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.config\opencode\skills"
-
-# 3. Remove existing links (safe for reinstalls)
-Remove-Item "$env:USERPROFILE\.config\opencode\plugins\superpowers.js" -Force -ErrorAction SilentlyContinue
-Remove-Item "$env:USERPROFILE\.config\opencode\skills\superpowers" -Force -ErrorAction SilentlyContinue
-
-# 4. Create plugin symlink (requires Developer Mode or Admin)
-New-Item -ItemType SymbolicLink -Path "$env:USERPROFILE\.config\opencode\plugins\superpowers.js" -Target "$env:USERPROFILE\.config\opencode\superpowers\.opencode\plugins\superpowers.js"
-
-# 5. Create skills junction (works without special privileges)
-New-Item -ItemType Junction -Path "$env:USERPROFILE\.config\opencode\skills\superpowers" -Target "$env:USERPROFILE\.config\opencode\superpowers\skills"
-
-# 6. Restart OpenCode
-```
-
-#### Git Bash
-
-Note: Git Bash's native `ln` command copies files instead of creating symlinks. Use `cmd //c mklink` instead (the `//c` is Git Bash syntax for `/c`).
+# Optionally remove the cloned repo
+rm -rf ~/.config/opencode/superpowers
 
-```bash
-# 1. Install Superpowers
-git clone https://github.com/obra/superpowers.git ~/.config/opencode/superpowers
-
-# 2. Create directories
-mkdir -p ~/.config/opencode/plugins ~/.config/opencode/skills
-
-# 3. Remove existing links (safe for reinstalls)
-rm -f ~/.config/opencode/plugins/superpowers.js 2>/dev/null
-rm -rf ~/.config/opencode/skills/superpowers 2>/dev/null
-
-# 4. Create plugin symlink (requires Developer Mode or Admin)
-cmd //c "mklink \"$(cygpath -w ~/.config/opencode/plugins/superpowers.js)\" \"$(cygpath -w ~/.config/opencode/superpowers/.opencode/plugins/superpowers.js)\""
-
-# 5. Create skills junction (works without special privileges)
-cmd //c "mklink /J \"$(cygpath -w ~/.config/opencode/skills/superpowers)\" \"$(cygpath -w ~/.config/opencode/superpowers/skills)\""
-
-# 6. Restart OpenCode
+# Remove skills.paths from opencode.json if you added one for superpowers
 ```
 
-#### WSL Users
-
-If running OpenCode inside WSL, use the [macOS / Linux](#macos--linux) instructions instead.
-
-#### Verify Installation
-
-**Command Prompt:**
-```cmd
-dir /AL "%USERPROFILE%\.config\opencode\plugins"
-dir /AL "%USERPROFILE%\.config\opencode\skills"
-```
-
-**PowerShell:**
-```powershell
-Get-ChildItem "$env:USERPROFILE\.config\opencode\plugins" | Where-Object { $_.LinkType }
-Get-ChildItem "$env:USERPROFILE\.config\opencode\skills" | Where-Object { $_.LinkType }
-```
-
-Look for `<SYMLINK>` or `<JUNCTION>` in the output.
-
-#### Troubleshooting Windows
-
-**"You do not have sufficient privilege" error:**
-- Enable Developer Mode in Windows Settings, OR
-- Right-click your terminal → "Run as Administrator"
-
-**"Cannot create a file when that file already exists":**
-- Run the removal commands (step 3) first, then retry
-

-## Skill Locations
-
-OpenCode discovers skills from these locations:
-
-1. **Project skills** (`.opencode/skills/`) - Highest priority
-2. **Personal skills** (`~/.config/opencode/skills/`)
-3. **Superpowers skills** (`~/.config/opencode/skills/superpowers/`) - via symlink
+## How It Works
 
-## Features
+The plugin does two things:
 
-### Automatic Context Injection
-
-The plugin automatically injects superpowers context via the `experimental.chat.system.transform` hook. This adds the "using-superpowers" skill content to the system prompt on every request.
-
-### Native Skills Integration
-
-Superpowers uses OpenCode's native `skill` tool for skill discovery and loading. Skills are symlinked into `~/.config/opencode/skills/superpowers/` so they appear alongside your personal and project skills.
+1. **Injects bootstrap context** via the `experimental.chat.system.transform` hook, adding superpowers awareness to every conversation.
+2. **Registers the skills directory** via the `config` hook, so OpenCode discovers all superpowers skills without symlinks or manual config.
 
 ### Tool Mapping
 
-Skills written for Claude Code are automatically adapted for OpenCode. The bootstrap provides mapping instructions:
+Skills written for Claude Code are automatically adapted for OpenCode:
 
 - `TodoWrite` → `todowrite`
 - `Task` with subagents → OpenCode's `@mention` system
 - `Skill` tool → OpenCode's native `skill` tool
 - File operations → Native OpenCode tools
 
-## Architecture
-
-### Plugin Structure
-
-**Location:** `~/.config/opencode/superpowers/.opencode/plugins/superpowers.js`
-
-**Components:**
-- `experimental.chat.system.transform` hook for bootstrap injection
-- Reads and injects the "using-superpowers" skill content
-
-### Skills
-
-**Location:** `~/.config/opencode/skills/superpowers/` (symlink to `~/.config/opencode/superpowers/skills/`)
-
-Skills are discovered by OpenCode's native skill system. Each skill has a `SKILL.md` file with YAML frontmatter.

-2. Check symlink/junction: `ls -l ~/.config/opencode/plugins/` (macOS/Linux) or `dir /AL %USERPROFILE%\.config\opencode\plugins` (Windows)
-3. Check OpenCode logs: `opencode run "test" --print-logs --log-level DEBUG`
-4. Look for plugin loading message in logs
+1. Check OpenCode logs: `opencode run --print-logs "hello" 2>&1 | grep -i superpowers`
+2. Verify the plugin line in your `opencode.json` is correct
+3. Make sure you're running a recent version of OpenCode
 
 ### Skills not found
 
-1. Verify skills symlink: `ls -l ~/.config/opencode/skills/superpowers` (should point to superpowers/skills/)
-2. Use OpenCode's `skill` tool to list available skills
-3. Check skill structure: each skill needs a `SKILL.md` file with valid frontmatter
