Uninstall command

curl -fsSL https://raw.githubusercontent.com/derHaken/SuperAntigravity/main/uninstall.sh | bash
The script will ask for confirmation before removing anything.

​
What gets removed

The uninstaller removes the following:
1

Skills

All 19 skill directories are deleted from ~/.gemini/antigravity/skills/.
2

Workflows

All 16 workflow files are deleted from ~/.gemini/antigravity/global_workflows/.
3

Agents

Six core agent files are deleted from ~/.gemini/antigravity/agents/: code-reviewer, backend-architect, frontend-architect, security-engineer, deep-research, and system-architect.
The socratic-mentor and repo-index agent files are not removed by the uninstaller. Delete them manually if needed: rm ~/.gemini/antigravity/agents/socratic-mentor.md ~/.gemini/antigravity/agents/repo-index.md
4

GEMINI.md bootstrap block

The # SuperAntigravity Skills block is stripped from ~/.gemini/GEMINI.md. The script uses a Python regex to find the marker and remove everything from it to the end of the file, then saves the cleaned content.

​
What does NOT get removed

  • Your ~/.gemini/GEMINI.md file — only the SuperAntigravity block is stripped. Any content you added before or after the block is preserved.
  • The ~/.gemini/antigravity/ directory itself — the parent directory is left in place in case you have other files there.
  • Any skills, workflows, or agents you created yourself — the uninstaller only removes files it knows about from the original install. Custom files you added are not touched.
  • socratic-mentor and repo-index agents — these two agents are not in the uninstaller’s removal list. Remove them manually if needed.
  • The install marker file — ~/.gemini/antigravity/.superantigravity-installed is not removed by the uninstaller. Remove it manually with rm ~/.gemini/antigravity/.superantigravity-installed if you want a fully clean state.
If the uninstaller does not find the # SuperAntigravity Skills marker in your GEMINI.md, it will warn you and skip that step. This can happen if you manually removed the block or never completed a full install.

​
Reinstalling after uninstall

Once uninstalled, you can reinstall from scratch with the same install command: 
curl -fsSL https://raw.githubusercontent.com/derHaken/SuperAntigravity/main/install.sh | bash
The installer checks for the # SuperAntigravity Skills marker before appending the bootstrap block. If the uninstaller already removed it, the reinstall proceeds cleanly.
If you want to update SuperAntigravity to a newer version, run the uninstall script first, then run the install script. This ensures you get fresh copies of all skills, workflows, and agents rather than stale files from a previous install.

​
The install marker file

When the installer completes successfully, it writes a marker file to ~/.gemini/antigravity/.superantigravity-installed containing the version and install date: 
superantigravity-version=1.0.0
install-date=2026-01-15T10:30:00Z
The installer uses this file to detect a previous install and warn you before overwriting. The uninstaller removes it as part of cleanup.
