Jesse Vincent 505a13e629 docs(porting): correct Antigravity to the install-existing-plugin path
This session proved agy does not need a bespoke scaffold: `agy plugin
install <repo-url>` imports the Claude Code plugin's skills AND its
SessionStart hook, which agy runs — so the bootstrap fires the Shape-A way
with no new files (verified: brainstorming auto-triggers on agy 1.0.3).

Replace the doc's now-false 'agy ships a generated ANTIGRAVITY.md context
file via .antigravity-plugin/install.sh' framing throughout:

- Part 2: Antigravity is the marquee 'you may not need a new directory'
  case; install the existing plugin and run the acceptance test before
  building anything.
- Part 4: add the inverse-of-a-fork-warning (a derived harness may inherit
  the parent's hook execution); replace the routing row with
  'installs an existing plugin directly, including its hook'.
- Step 5 / Part 6: bootstrap escalation now leads with 'check for an
  inherited hook'; if a manifest names a context file, point it at the real
  using-superpowers/SKILL.md — never generate a wrapped copy at install time.
- Appendix A: add the Antigravity row. Appendix B: add two gotchas.

Note: references to references/antigravity-tools.md and tests/antigravity/
depend on PR #1657 landing on dev.

Superpowers for OpenCode

Complete guide for using Superpowers with OpenCode.ai.

Installation

Add superpowers to the plugin array in your opencode.json (global or project-level):

{
  "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.

If you previously installed superpowers using git clone and symlinks, remove the old setup:

# 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

Finding Skills

Use OpenCode's native skill tool to list all available skills:

use skill tool to list skills

Loading a Skill

use skill tool to load brainstorming

Personal Skills

Create your own skills in ~/.config/opencode/skills/:

mkdir -p ~/.config/opencode/skills/my-skill

Create ~/.config/opencode/skills/my-skill/SKILL.md:

---
name: my-skill
description: Use when [condition] - [what it does]
---

# My Skill

[Your skill content here]

Project Skills

Create project-specific skills in .opencode/skills/ within your project.

Skill Priority: Project skills > Personal skills > Superpowers skills

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, use a branch or tag:

{
  "plugin": ["superpowers@git+https://github.com/obra/superpowers.git#v5.0.3"]
}

How It Works

The plugin does two things:

  1. Injects bootstrap context via the experimental.chat.messages.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 speak in actions rather than naming any one runtime's tools. On OpenCode these resolve to:

  • "Create a todo" / "mark complete in todo list" → todowrite
  • Subagent (general-purpose): template → OpenCode's 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

(Verified against the installed OpenCode CLI's tool inventory.)

Troubleshooting

Plugin not loading

  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

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:

npm install superpowers@git+https://github.com/obra/superpowers.git --prefix "$HOME\.config\opencode"

Then use the installed package path in opencode.json:

{
  "plugin": ["~/.config/opencode/node_modules/superpowers"]
}

Skills not found

  1. Use OpenCode's skill tool to list available skills
  2. Check that the plugin is loading (see above)
  3. Each skill needs a SKILL.md file with valid YAML frontmatter

Bootstrap not appearing

  1. Check OpenCode version supports experimental.chat.messages.transform hook
  2. Restart OpenCode after config changes
