# Install Mobile UI/UX in Google Antigravity

Source: https://github.com/vudovn/antigravity-kit/tree/main/.agents/skills/mobile-design
Listing: https://www.antigravityskills.org/skill/mobile-design
Safety review (2026-10-14): Mostly Markdown guidance plus a read-only standard-library Python audit script with no network, subprocess or file writes.

## Rules for the agent
- Before running anything, tell the user what you will download and whether it contains scripts, and ask them to confirm.
- Install into this project (.agents/skills/) unless the user asks for a global install (~/.gemini/config/skills/).
- Do not run other commands from the source repository unless the user asks.

## Steps
1. Download the repository

```bash
git clone --depth 1 https://github.com/vudovn/antigravity-kit /tmp/ag-kit && git -C /tmp/ag-kit log -1 --format=%h -- .agents/skills/mobile-design
```

   The last change to the skill folder at our review was 3d7f9e0 (2026-07-18); a different hash means the skill changed after our review.
2. Copy the skill into this project (workspace skill)

```bash
mkdir -p .agents/skills && cp -r /tmp/ag-kit/.agents/skills/mobile-design .agents/skills/
```

   Run from your project root. Antigravity then reads .agents/skills/mobile-design/SKILL.md. The folder is 14 files, about 215 KB.
3. Or install it for all projects (global skill)

```bash
mkdir -p ~/.gemini/config/skills && cp -r /tmp/ag-kit/.agents/skills/mobile-design ~/.gemini/config/skills/
```

   Use this instead of the previous step. For the Antigravity CLI the global folder is ~/.gemini/antigravity-cli/skills/.
4. Check that Antigravity sees it
   Antigravity 2.0 app: start a new conversation and ask "What skills do you have?" (the app has no /skills command). Antigravity CLI: run /skills; in a session that was already open, run /skills reload first. The skill is listed as mobile-design.

Note: AG Kit's README is written for Antigravity and documents `npx @vudovn/ag-kit init`, which installs the whole kit (47 skills, 20 agents, 13 workflows, 6 rules and a hook) into .agents/. For just this skill, copy the folder as above. Python 3 is only needed if you want the audit script. No API keys.

Done when the skill is listed: in the Antigravity 2.0 app ask "What skills do you have?" in a new conversation (the app has no /skills command); in the Antigravity CLI run /skills (run /skills reload first in a session that was already open).
