Antigravity guide

Best agent Skills for Antigravity IDE

Antigravity IDE is the one agent where the first question is not what to install but what you already have: it ships with the awesome-skills bundle pre-installed, so the useful move is adding the few high-value Skills the bundle does not cover — frontend-design for UI direction, firebase-hosting for deploys, and Composio for tool routing. 36 of 191 catalogued Skills are verified here, and audit beats accumulation on this surface.

Install first

frontend-design

The highest-scoring Skill we catalogue and verified on Antigravity. Bundled Skill sets tend to be broad and shallow on visual judgement; this is the one that changes design output rather than adding another capability.

Best when: UI work where the result should look intentional.

Install model

How Skills install on Antigravity

antigravity-awesome-skills install --skill frontend-design
  1. 1Check what is already installed before adding anything — Antigravity ships with a large bundle, and duplicates cost frontmatter tokens at every session start.
  2. 2Install additions with the bundle CLI, using the command shown on each Skill page.
  3. 3Restart the session so new Skill metadata is read.
  4. 4Trigger the Skill and verify the behaviour changed rather than assuming the install took.

Because Antigravity pre-installs a large Skill set, the cost model inverts relative to other agents. Elsewhere you pay to add capability; here you already pay frontmatter tokens for Skills you may never trigger, and precision suffers when many descriptions compete for the same task. Pruning is a legitimate optimisation on this agent.

Why these

Pick by pick

  1. 1
    frontend-design

    The highest-scoring Skill we catalogue and verified on Antigravity. Bundled Skill sets tend to be broad and shallow on visual judgement; this is the one that changes design output rather than adding another capability.

  2. 2
    antigravity-awesome-skills

    The bundle itself — MIT, 22K stars, verified on five agents. Listed here because knowing what is in it is the prerequisite for deciding what to add, and because you can install it deliberately on other agents too.

  3. 3
    firebase-hosting-basics

    Google-published, one-step deploy to Firebase Hosting, and one of the highest-scoring Skills verified on Antigravity. Deploy paths are the gap bundles most often leave.

  4. 4
    composio

    Apache-2.0 and verified on every agent target we list. Broad third-party reach from one install, which is exactly what a general-purpose bundle cannot provide.

  5. 5
    debug

    Anthropic-authored, verified on Antigravity, and it changes behaviour on the most expensive class of session: an unexplained failure met with speculative edits.

  6. 6
    architecture-adr

    Turns architectural decisions into written records instead of leaving them in a chat log. On an agent that makes generating code very cheap, writing down why is what stops the codebase becoming unexplainable.

Limits

What this agent cannot do

The pre-installed bundle is a real convenience and a real cost: Skills you never trigger still consume frontmatter tokens at session start, and a crowded Skill set makes triggering less precise because many descriptions compete for the same task. 36 of 191 catalogued Skills are verified on Antigravity, and a substantial share of those are Anthropic pack Skills — so check each entry's agent badges rather than assuming a Skill that works in Claude Code works here. Audit what you have before installing more.

FAQ

Common questions

Do I need to install Skills in Antigravity at all?

Not to get started — it ships with a large bundle pre-installed. Installing is for the specific gaps the bundle leaves, which in practice are visual design judgement, deploy paths, and broad third-party integration.

Does a big pre-installed Skill set slow the agent down?

It costs tokens rather than speed: each Skill contributes roughly 100 tokens of frontmatter at session start whether it fires or not. The subtler cost is triggering precision — when many descriptions overlap, the wrong Skill fires more often.

Can I remove Skills that ship with Antigravity?

Yes, and on this agent it is a reasonable thing to do. Pruning Skills you never trigger reduces both the per-session token floor and the competition between overlapping descriptions.
