+# Installing Superpowers for OpenCode
+
+## Prerequisites
+
+- [OpenCode.ai](https://opencode.ai) installed
+
+## Installation
+
+Add superpowers to the `plugin` array in your `opencode.json` (global or project-level):
+
+```json
+{
+  "plugin": ["superpowers@git+https://github.com/obra/superpowers.git"]
+}
+```
+
+Restart OpenCode. The plugin installs through OpenCode's plugin manager and
+registers all skills.
+
+Verify by asking: "Tell me about your superpowers"
+
+OpenCode uses its own plugin install. If you also use Claude Code, Codex, or
+another harness, install Superpowers separately for each one.
+
+## Migrating from the old symlink-based install
+
+If you previously installed superpowers using `git clone` and symlinks, remove the old setup:
+
+```bash
+# Remove old symlinks
+rm -f ~/.config/opencode/plugins/superpowers.js
+rm -rf ~/.config/opencode/skills/superpowers
+
+# Optionally remove the cloned repo
+rm -rf ~/.config/opencode/superpowers
+
+# Remove skills.paths from opencode.json if you added one for superpowers
+```
+
+Then follow the installation steps above.
+
+## Usage
+
+Use OpenCode's native `skill` tool:
+
+```
+use skill tool to list skills
+use skill tool to load brainstorming
+```
+
+## Updating
+
+OpenCode installs Superpowers through a git-backed package spec. Some OpenCode
+and Bun versions pin that resolved git dependency in a lockfile or cache, so a
+restart may not pick up the newest Superpowers commit. If updates do not appear,
+clear OpenCode's package cache or reinstall the plugin.
+
+To pin a specific version:
+
+```json
+{
+  "plugin": ["superpowers@git+https://github.com/obra/superpowers.git#v5.0.3"]
+}
+```
+
+## Troubleshooting
+
+### Plugin not loading
+
+1. Check logs: `opencode run --print-logs "hello" 2>&1 | grep -i superpowers`
+2. Verify the plugin line in your `opencode.json`
+3. Make sure you're running a recent version of OpenCode
+
+### Windows install issues
+
+Some Windows OpenCode builds have upstream installer issues with git-backed
+plugin specs, including cache paths for `git+https` URLs and Bun not finding
+`git.exe` even when it works in a normal terminal. If OpenCode cannot install
+the plugin, try installing with system npm and pointing OpenCode at the local
+package:
+
+```powershell
+npm install superpowers@git+https://github.com/obra/superpowers.git --prefix "$HOME\.config\opencode"
+```
+
+Then use the installed package path in `opencode.json`:
+
+```json
+{
+  "plugin": ["~/.config/opencode/node_modules/superpowers"]
+}
+```
+
+### Skills not found
+
+1. Use `skill` tool to list what's discovered
+2. Check that the plugin is loading (see above)
+
+### Tool mapping
+
+Skills speak in actions ("create a todo", "dispatch a subagent", "read a file"). On OpenCode these resolve to:
+
+- "Create a todo" / "mark complete in todo list" → `todowrite`
+- `Subagent (general-purpose):` template → `task` tool with `subagent_type: "general"` (or `"explore"` for codebase exploration)
+- "Invoke a skill" → OpenCode's native `skill` tool
+- "Read a file" → `read`
+- "Create a file" / "edit a file" / "delete a file" → `apply_patch`
+- "Run a shell command" → `bash`
+- "Search file contents" / "find files by name" → `grep`, `glob`
+- "Fetch a URL" → `webfetch`
