A TypeScript plugin for the Opencode CLI that authenticates with Google via OAuth so users can use their existing Gemini plan and quotas (including the free tier) inside Opencode. It handles the OAuth browser flow, local callback capture, and Google Cloud project provisioning.

Use cases

• authenticate opencode cli with my google gemini account
• use gemini code assist free tier in opencode
• log in to gemini via oauth instead of api key
• check my gemini code assist quota usage
• use google ai pro subscription with opencode

When to choose

• you use Opencode and want to reuse an existing Gemini subscription or free-tier quota instead of paying per API key
• you prefer Google account OAuth login over managing API keys
• you need quota inspection for Gemini Code Assist

When to avoid

• you rely on individual, Google AI Pro, or Google AI Ultra OAuth access, which Google deprecated in June 2026
• you want the lowest-risk option - use a Gemini API key directly instead, since third-party OAuth use may violate Google policy
• you don't use the Opencode CLI
