Your commit assistant in Antigravity is not generating a message or returns an empty or failed suggestion when you try to commit. This often happens right after staging changes or clicking the AI commit action in your editor.

Antigravity commit message not generated or empty

Developers report Antigravity showing no output or a brief error such as Error generating commit message with no details. Typical symptoms are a spinner that stops without text, an empty suggestion box, or a generic failure when the feature is invoked from the editor. If you want a deeper breakdown of this specific Antigravity behavior, see our focused notes in this commit message issue fix.

Solution Overview

Aspect	Detail
Root Cause	Staged diff unavailable or too large, temporary service outage or quota, stale extension session, or local hooks blocking commit flows
Primary Fix	Ensure a small staged diff exists, update and restart the Antigravity extension, reauthenticate, and retry
Complexity	Easy
Estimated Time	10 to 20 minutes

Fix commit message generation in Antigravity

Step by Step Solution

1. Confirm you have a staged diff and keep it focused

Antigravity usually needs staged changes. If nothing is staged or the diff is huge or binary heavy, message generation can fail. Run these commands in your repo root:

git status
git diff --staged

If nothing is staged, stage a minimal set of files and retry:

git add path/to/file1 path/to/file2
git diff --staged

If the diff is enormous or includes large generated artifacts, commit in smaller chunks first. If you often meet a token bound issue during generation, review techniques to reduce context size in this token limit troubleshooting.

2. Update the Antigravity extension and reload your editor

A stale extension build or corrupted session is a common cause.

• VS Code

– Open Extensions panel and update Antigravity if an update is available – Run Command Palette then Developer Reload Window

• JetBrains IDEs

– Open Plugins then update Antigravity and restart the IDE After reload, try the commit message action again.

3. Reauthenticate and check network or quota

Sessions can expire or be blocked by network settings.

• Sign out from the Antigravity extension panel then sign back in
• Ensure your network allows outbound requests and that no corporate proxy is blocking requests
• If you use a proxy, configure it in your system and editor settings, then retry
• Confirm your AI quota and rate limits are healthy. See current guidance on limits in the Gemini docs: Rate limits

4. Clear extension cache and reinitialize

Clearing cached state resolves many silent failures.

• VS Code cache locations

– Windows: %AppData%\Code\User\globalStorage – macOS: ~/Library/Application Support/Code/User/globalStorage – Linux: ~/.config/Code/User/globalStorage Close the editor, back up the Antigravity extension folder inside globalStorage, remove it, then reopen the editor and sign in again. You can also inspect logs via the editor

• VS Code Command Palette then Developer Open Extension Logs to look for request errors

5. Rule out Git hooks or templates blocking the flow

Custom hooks can veto commit paths or interfere with message editing. Check for hooks:

ls .git/hooks

Temporarily disable commit message hooks to test:

mv .git/hooks/commit-msg .git/hooks/commit-msg.bak 2>/dev/null || true
mv .git/hooks/prepare-commit-msg .git/hooks/prepare-commit-msg.bak 2>/dev/null || true

If a global commit template is prefilled and confusing the assistant, inspect and remove it:

git config --global --get commit.template
git config --global --unset commit.template

Retry message generation. Restore hooks after testing:

mv .git/hooks/commit-msg.bak .git/hooks/commit-msg 2>/dev/null || true
mv .git/hooks/prepare-commit-msg.bak .git/hooks/prepare-commit-msg 2>/dev/null || true

6. Retry with a smaller selection and clear binary files

Large or binary diffs can silently fail. Exclude big files and vendor folders, then restage:

git reset
git add src app packages
git reset -- vendor dist build node_modules
git diff --staged

Invoke Antigravity on this reduced diff. If you are working inside a Stitch based workspace and the project itself fails to initialize cleanly, that can block commit helpers. For that scenario, review this Stitch project loading guide and then retry the commit assistant.

Alternative Fixes and Workarounds

Use a local commit template when the service is flaky

Create a lightweight template to keep moving:

cat > ~/.gitmessage.txt << 'EOF'
type scope subject

body

footer
EOF

git config --global commit.template ~/.gitmessage.txt

Follow the Conventional Commits spec while the assistant is unavailable: Conventional Commits

Generate suggestions from only the last commit sized diff

Stage and commit with a temporary message, then immediately rewrite with a refined message once the assistant recovers:

git add -A
git commit -m "temp"
After the assistant works, run an amend
git commit --amend

Switch to a minimal test repo to isolate

Create a new repo with a tiny change to eliminate repo specific issues:

mkdir antigravity-test && cd antigravity-test
git init
echo "hello" > demo.txt
git add demo.txt
git diff --staged

If Antigravity works here, the problem is specific to your main repo size or configuration.

Troubleshooting Tips

• Check editor and extension logs right after a failed generation to capture the first error
• Verify your system time is correct as clock drift can break authentication
• Disable other AI or Git related extensions temporarily to avoid conflicts
• Confirm that no pre commit tools auto stage or unstage files while you request a message
• If the service had a recent outage, wait a short time and retry. Track general incidents on vendor status pages such as Google Cloud Status Dashboard

Best Practices

• Keep diffs small and focused before asking for an AI message
• Avoid committing large binary assets in the same change as code edits
• Update the Antigravity extension regularly and restart your editor weekly
• Keep a local Conventional Commit template as a fallback
• Document any Git hooks your team uses and test the AI assistant with hooks disabled during setup

Final Thought

The fastest path is to stage a small diff, update and relaunch the extension, then reauth and retry. These steps resolve the majority of silent message failures and keep your commits consistent while you continue shipping.
