[Feature Request] Add Google Antigravity IDE as a supported agent

[skybound-raz]

Description

Entire currently supports claude-code and gemini (Gemini CLI) as agents. We'd love to see support for Google Antigravity IDE — Google's AI coding IDE that supports multiple models (Gemini, Claude, etc.).

Use Case

We run a multi-project portfolio (15+ repos) with Entire enabled across all of them using --agent gemini --strategy auto-commit. Our primary development happens in Antigravity IDE, not the Gemini CLI terminal. As a result:

• ✅ Git commits and pushes work normally
• ✅ Entire hooks fire on every commit
• ❌ Zero checkpoints are captured because no recognized agent session is detected
• ❌ Dashboard shows no activity despite active daily development

We've verified hooks are installed correctly, settings.json and settings.local.json are properly configured, and entire status reports "Enabled (auto-commit)." The issue is purely that Antigravity sessions aren't detected by the hooks.

Expected Behavior

Entire should detect and capture Antigravity IDE agent sessions the same way it does for Gemini CLI — capturing prompts, reasoning, file changes, and token usage as checkpoints.

Current Workaround

Using Gemini CLI in a terminal for commits when full session tracking is needed. This adds friction and means most of our day-to-day development goes untracked on the dashboard.

Environment

• Entire CLI: v0.4.2
• OS: macOS (Apple Silicon)
• IDE: Google Antigravity
• Agent config: entire enable --strategy auto-commit --agent gemini --force

According to official google engineers posting, for example here antigravity has no hook support.

✅ Git commits and pushes work normally
✅ Entire hooks fire on every commit

Can you confirm you only mean the git hooks from entire are firing, right?

[skybound-raz]

Good clarification — to confirm, yes, I'm referring to Entire's git hooks (commit-msg, post-commit, pre-push, prepare-commit-msg) that fire on standard git operations. Those hooks execute correctly on every commit/push.

The issue is that when those hooks run, they look for an active agent session (Gemini CLI process) to capture context from — and since Antigravity doesn't expose hook support or session data that Entire can detect, the hooks find nothing to capture and silently produce zero checkpoints.

So to be precise:

• ✅ Entire's git hooks fire on every commit — confirmed via hook scripts in .git/hooks/
• ❌ No agent session is detected because Antigravity has no hook/session interface for Entire to read from
• ❌ Result: 0 checkpoints, empty logs, blank dashboard

The feature request is essentially asking for Entire to add Antigravity as a recognized agent — which would likely require collaboration with the Antigravity team to expose the session data Entire needs.

With the launch of the new antigravity, this is possible. @blackgirlbytes I can pick this up and work on it.

thank you! Yes please work on it!

@savekirk please hold on for now. The docs are basically saying "it will use gemini hooks" so it might just work with the gemini integration we already have. Now my brief first try did not work, so looking now if the docs are wrong (they still mention .gemini/ which feels off) but I'm still optimistic this might just work. And probably we will have it as a integration in the cli repo
