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.

Every link below was opened and checked in September 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 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.

Official

• Antigravity - Home page and download.

Skill collections

Antigravity loads skills from .agents/skills/ in your workspace, one folder with a SKILL.md file per skill, so most collections written for other agents work here too. The global folder differs by program: skill locations in the docs.

• rmyndharis/antigravity-skills - A curated set put together for Antigravity first.
• addyosmani/agent-skills - Engineering skills by Addy Osmani: reviews, testing, performance, shipping (CLI).
• tech-leads-club/agent-skills - A registry where every skill is validated and security-checked before it is listed.
• sickn33/agentic-awesome-skills - Over two thousand skills with a CLI and a local MCP server to search them (CLI IDE).
• wshobson/agents - Plugin marketplace that installs into Antigravity, Claude Code, Codex, Cursor and others (CLI).

• samber/cc-skills-golang - Go skills from the author of lo.
• gamedev-skills/awesome-gamedev-agent-skills - 73 game development skills for Godot, Unity, Unreal, three.js and more, with a router that picks the right one.
• Pranav-Nexus/antigravity-skill-porter - Converts skills written for Claude Code or Cursor into Antigravity plugins: swaps the tool names, reads GEMINI.md and AGENTS.md, adds the plugin.json.

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.
• mksglu/context-mode - Keeps bulky tool output out of the context window and persists session memory (CLI IDE).
• ctxrs/ctx - Search the agent sessions already on your machine. Git blame for agent history.
• mattpocock/skills: handoff - A skill you call by name. It writes up a long session as one Markdown file so a fresh agent, another tool or a colleague can continue the work. Matt Pocock explains when to use it.

Code intelligence

• colbymchenry/codegraph - A local, pre-indexed graph of your code so the agent needs fewer tool calls (IDE).
• Graphify-Labs/graphify - Turns a codebase with its docs, schemas and PDFs into a knowledge graph you can query.
• zzet/gortex - Code-intelligence engine over CLI, MCP and API for 257 languages and several repositories at once.

Quota and usage monitors

• jlcodes99/vscode-antigravity-cockpit - Extension with a dashboard of your Antigravity model quotas.
• wusimpl/AntigravityQuotaWatcher - Extension that watches your Antigravity model quota (IDE).
• Dunphil692/antigravity-context-meter - Shows how full the context window is, as a macOS floating capsule or an IDE status bar item. Reads the local transcript, so it costs no tokens (IDE).
• Javis603/token-monitor - Desktop widget for tokens, cost and limits across many coding tools.
• xiufengsun/TokenTracker - Local usage and cost tracker that never reads your prompts.
• vinzdg/codenotch - macOS app that pins your usage limits to a screen edge.
• tddworks/ClaudeBar - macOS menu bar monitor for Claude, Codex, Antigravity and Gemini.

Safety

• google/mantis - Google's toolkit for agents that find, reproduce and patch vulnerabilities.

Running several agents

• awslabs/cli-agent-orchestrator - Coordinates several coding CLIs in separate tmux sessions (CLI).
• codeaholicguy/ai-devkit - One control plane for the coding agents on your machine.
• Observal/Observal - Self-hosted registry to share skills, MCP servers and agents inside a team (CLI).
• WFD Faro - Windows desktop panel for many projects at once: Git health, kanban, scripts. Closed source, free tier. The live view of your Antigravity subagents is part of the paid plan.

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. The whole thing is free and open: teach-it-once-kit.

I write about what I build and what broke on Substack. New skills show up there first.
