Superpowers port for Antigravity 2.0, IDE & CLI

Google Antigravity

Hey guys,

Wanted to share this here as superpowers helps me tremendously.

I’ve ported superpowers framework ( GitHub - obra/superpowers: An agentic skills framework & software development methodology that works. · GitHub ) to work natively with Antigravity 2.0, Antigravity IDE and Antigravity CLI.

I kept all the skills and prompt templates exactly the same, meaning this fork is fully backward-compatible with Claude Code and other systems. The changes in this port are focused entirely on adapting the tool mappings and subagent orchestrations to work natively with the new Antigravity 2.0 engine.

Here is a summary of what was changed to make it work:

* Added a plugin.json manifest so the Antigravity 2.0, Antigravity IDE and Antigravity CLI automatically discover and loads the plugin on startup.

* Created an antigravity-tools.md mapping file to translate upstream skill commands into Antigravity 2.0 tools (like mapping Read to view_file, Glob to find_by_name, and Bash to run_command).

* Integrated workspace isolation. The worktree setup now natively uses the Workspace: “branch” parameter inside invoke_subagent to isolate git branches automatically.

* Documented token-saving optimizations like using define_subagent for multi-agent plans.

* Wrote a new test suite under tests/antigravity/ that verifies plugin loading, skill triggering, and subagent dispatching.

v6.0.0 — Full native rebuild for Antigravity 2.0

The original port (linked in the post) used a tool mapping layer — skills were still written in Claude Code tool names and translated at runtime. It worked, but it cost tokens every session and added complexity.

I’ve since done a complete rebuild in a new repo: superpowers-antigravity

What’s different:

  • 86 files removed — all legacy platform code (Claude Code, Codex, Cursor, Copilot CLI, etc.) is gone

  • No more tool mapping — skills use view_file, run_command, invoke_subagent directly. Zero translation overhead

  • New capabilities — native generate_image mockups in brainstorming, browser-testing skill for UI verification, async subagent coordination with manage_task and schedule, rich plan formatting with Mermaid diagrams and diff blocks

  • Lighter subagents — reviewers use read-only TypeName: "research" instead of full agent clones

  • Manual install option — no git required, just download the ZIP

If you’re on Antigravity 2.0, switch to the new repo. The old one won’t receive updates.
