Wechat Ai Bridge

**How is this different from cc-weixin / wechat-acp?**

This project focuses on **session management** (`/new` `/resume` `/sessions`), **backend selection** (Claude + Codex), **Claude tool approval**, and **bidirectional file relay** — the same workflow family as [telegram-ai-bridge](https://github.com/AliceLJY/telegram-ai-bridge), now using WeChat transport.

**Do not use the `gemini` backend. This is an account-safety issue, not just a dead feature.**

This adapter reads `~/.gemini/oauth_creds.json` and reuses the Gemini CLI's own OAuth client to reach the internal Code Assist endpoint `cloudcode-pa.googleapis.com`. Google's FAQ names this exact pattern: *"Using third-party software, tools, or services to harvest or piggyback on Gemini CLI's OAuth authentication to access our backend services is a direct violation of our applicable terms and policies"*, and says it *"may be grounds for immediate suspension or termination of your account."* Paid subscribers have reportedly lost access over it. **This applies regardless of your plan tier — the prohibited thing is the mechanism, not the account type.**
