Awesome Antigravity

A curated list of skills, tools and resources for Google Antigravity, Google’s agentic development platform. It comes as three programs: Antigravity 2.0, a desktop app for running agents, the Antigravity CLI (agy) for the terminal, and the Antigravity IDE, plus extensions for VS Code, Visual Studio, JetBrains, Zed and Xcode.

If this list saved you some searching, my book Teach It Once shows how to take what your AI knows about you into files you own and teach it your work and your rules once. The first chapters are a free sample.

I also write about building with AI agents, what works and what broke, in a free newsletter: subscribe on Substack.

Every link below was opened and checked in October 2026 (check log). Projects that only exist to share accounts, dodge quotas or get around regional limits are left out on purpose. If something here is dead or missing, open a pull request.

A tag such as CLI or IDE at the end of an entry names the Antigravity program it works in, as stated by the project. No tag means the project does not say.

Common questions

Questions people asked in the Antigravity forums in September 2026, each with the place on this page that answers it.

How do I keep memory between conversations? See the section Memory and context. To carry one long session into a fresh one, the handoff skill listed there writes it up as a file the next agent reads.

How do I install a skill I found on GitHub? Put it into the project you are working in: the skill’s folder goes into .agents/skills/ in that project, and all three Antigravity programs read it there. To have it in every project, copy the folder into the global folder of the program you use, listed on Google’s skills page. One trap: the “global” option of some popular installers writes to ~/.agents/skills/, which Antigravity does not read today (CLI issue #103, installer fix #1483, both still open on 2026-09-30). If a skill you installed does not show up, look in which folder it landed.

My workflows stop working on 1 November. What do I do? Google retires workflows on 1 November 2026; after that, workflow folders are no longer read. Type /migrate-workflows to turn them into skills. It looks in .agents/workflows/ in your workspace and in ~/.gemini/config/workflows/, and keeps your old files as .bak. Google changes Antigravity often; my free newsletter sends one short email when Google changes something that breaks a setup, with the fix: subscribe on Substack.

How do I see how much quota I have left? In the CLI, type /usage. For a view that stays on screen, see the section Quota and usage monitors.

How do I fork or copy a conversation? In the CLI, /fork clones the conversation up to the current turn into a new session. It copies the thread, not your files.

Which rules and workflows do people use? See the section Guides and tips.

How do I switch between several accounts? Tools that swap or share accounts are left out of this list on purpose.

Single skills worth installing

• nextlevelbuilder/ui-ux-pro-max-skill - Design knowledge for building interfaces that do not look generated.
• Nanako0129/sepia - Rewrites prose so it stops reading as machine-written. Has a native Antigravity plugin (CLI).
• amElnagdy/delegate-skills - Hand a task to a second coding agent, review its diff, land the commit yourself (CLI).
• strip-ai-tells - Edits prose so it stops sounding machine-written and hands back the edited text, not a report. By the maintainer of this list. A folder ready to copy into .agents/skills/ (Antigravity, Codex) or .claude/skills/ (Claude Code) is in this repository.
• n8n vibe coding skill - Build n8n workflows from inside the agent. Lives in this repository.

Spec-driven development

• gemini-cli-extensions/conductor - Specify, plan, then implement. Works in Antigravity and Claude Code (CLI).
• gotalab/cc-sdd - A small harness that turns an approved spec into a long autonomous run.

Memory and context

• CaviraOSS/LongMemory - Local memory store your agent keeps between sessions.

Fixes and quality of life

• FutureisinPast/antigravity-conversation-fix - Repairs missing and out-of-order conversation history (IDE).
• PeonPing/peon-ping - A Warcraft peon tells you when the agent is done, so you can stop watching the terminal.

Known CLI problems

Compiled on 2026-09-21 from the most discussed threads on Google’s own issue tracker for the CLI, which had 662 open issues that day. Nothing here was tested or reproduced by this list. Each line gives the error as reported, its status, and the thread. Google’s troubleshooting page covers four other things: the shell PATH, keyring permissions, clipboard forwarding and the self-updater.

• #44 “Agent execution terminated due to error” - Open since 2026-05-20. The reporter says it happens every time and that signing in again does not help.
• #415 “1.0.9 update breaks authentication” - After the update the CLI stops at “Eligibility check failed”. Closed on 2026-09-18 as obsolete. The maintainer asks for a new issue if it still happens on 1.2.6.
• #76 agy --print drops its output when not run in a terminal - Hits pipes, subprocesses and redirects. Closed. A maintainer names 1.0.15 for the Windows part and 1.1.1 for silent server errors and hangs in scripts.
• #34 “Illegal instruction” during install - Closed on 2026-06-24. Users on a Raspberry Pi 4 report it fixed in 1.0.10.
• #105 “Subagents Not Registering” - Closed on 2026-07-28. No fixed version is named in the thread. Users share workarounds there.
• #103 “User skills aren’t picked up from ~/.agents/skills” - Open since 2026-05-21. The docs name ~/.gemini/antigravity-cli/skills/ as the CLI’s global skills folder.

Guides and tips

• ykdojo/antigravity-cli-tips - Practical tips for the Antigravity CLI (agy) by YK Sugi of CS Dojo: aliases, a custom status line, an agent-run development cycle.
• The unofficial Antigravity guide - Setup, core concepts and working habits. Lives in this repository.

From the maintainer

I’m Michael Zelbel. Apart from this list I build a personal AI that runs on my own machines: it remembers what I tell it, does the small repeated jobs on its own and messages me first when something needs me. It is called Godspeed Mission Control, and the whole thing is free and open: godspeed-mission-control.

I write about what I build and what broke on Substack.
