[feedback wanted]: Gemini CLI stops for individual users on June 18

[slkiser]

Google says Gemini CLI / Gemini Code Assist individual usage will stop serving requests on June 18, 2026 as users transition to Antigravity CLI.

If you use Gemini CLI with opencode-quota, please share:

• Are you moving to Antigravity CLI?
• Which companion plugin, if any, should opencode-quota support for Antigravity CLI?
• Should opencode-quota support Antigravity CLI quota/status if possible?
• Will you stop using this provider?
• What quota/status info would help during the transition?

Hi there,

As a user of the opencode-gemini-auth plugin, and in light of the upcoming transition to the Antigravity CLI on June 18, 2026, I've created a new plugin inspired by the opencode-gemini-auth approach: opencode-agy-auth.

I've implemented an agy_quota tool within it to retrieve the quota for the new AntiGravity API, and I've just opened a draft PR for this implementation.

Since I haven't seen any other projects tackling the Antigravity transition yet, I wanted to share this.
Consider it a proposal or proof-of-concept, it's currently working well on my end.

Let me know your thoughts. 🙏

Looks great! I'd add a config to truncate model quotas in the interfaces (TUI and/or toasts). I'll come back again after I handle the issues/PRs that accumulated.

I have modified the PR to return truncated output by default 🫡

I have changed the output to be similar with the Antigravity IDE client

In the cli:

> node dist/bin/opencode-quota.js show --provider google-agy
[Google Agy]
Claude and GPT models                           4d

In the IDE:
