Walkthrough

This change removes all support for the "Claude Code" channel type (type 53) and its OAuth integration from both backend and frontend. It deletes related constants, adaptors, OAuth controllers and services, token refresh logic, UI handling, and all special-case logic for Claude Code, reverting affected areas to generic channel/channel-type handling.

Poem

The Claude Code bunny hops away,
OAuth dreams now tucked astray.
No more tokens split in two,
Or indigo prompts in the queue.
The UI is lighter, the backend clean—
A simpler warren, neat and serene!

web/src/components/table/channels/modals/EditChannelModal.jsx (3)

20-60: Import statements look good after OAuth removal

The imports are clean and appropriate for the component's current functionality without OAuth support.

---

791-791: Good UX improvement: Disable batch mode in edit mode

Disabling the batch creation checkbox when editing prevents user confusion since batch mode only applies to channel creation, not editing.

---

1635-1640: Excellent improvement to system prompt handling

The changes make system prompt behavior consistent across all channel types:

• Clear placeholder text explains the priority hierarchy
• The showClear prop improves usability
• The extra text provides helpful context about user prompt priority

This unification simplifies the codebase and improves user experience.

Hi folks — I’m a bit confused about why this feature was reverted, and I’m not sure how I’m supposed to use/configure this channel in the current design.

From what I can tell, this revert removes the dedicated “Claude Code” channel (type 53) and its associated OAuth/token refresh + frontend special-case config, and returns to a more “all channels are treated the same” approach.

I’m currently blocked on two things:

1. What was the reason for the revert?
   Was it due to instability in the OAuth flow, security concerns, maintenance overhead, or a change in Claude Code’s upstream requirements? Is there a clear rationale / forward plan (e.g., reintroduce via a different approach vs. discontinue support)?

2. In the current design, what is the correct way to use/configure this channel?
   Now that the Claude Code–specific channel is gone, it seems like the only option is to go through the generic channel path. Concretely:

• If the goal is to route to Claude (Anthropic/Claude API), what channel type / api_type should be used?
• Since the previous Claude Code special handling (prompt/routing/auth) is removed, what’s the recommended configuration now (e.g., base_url + API key, OpenAI-compatible mode, custom headers, etc.)?
• Previously OAuth/token refresh was required — is there an equivalent replacement now? If not, does that imply this “Claude Code” path is currently unsupported or not recommended?

My end goal is to make the same requests work reliably without relying on the Claude Code–specific channel. Any guidance on the recommended config for the current version (even a short example or link to docs) would be hugely appreciated. Thanks! 🙏

大家好——我有点不太理解这个功能为什么会被 revert（回滚），也不清楚在当前的设计下应该如何使用/配置这个渠道。

就我看到的情况，这次 revert 移除了专门的 “Claude Code” 渠道（type 53），以及它相关的 OAuth / token 刷新 + 前端的特殊配置逻辑，整体回到了更偏向“所有 channel 一视同仁”的通用实现方式。

我现在主要被两件事卡住了：

1. 这次 revert 的原因是什么？
   是因为 OAuth 流程不稳定、安全方面的顾虑、维护成本过高，还是 Claude Code 上游的要求发生了变化？有没有一个明确的理由/后续计划（比如会用另一种方式重新引入，还是决定不再支持）？

2. 在当前设计下，正确的使用/配置方式是什么？
   既然 Claude Code 专用 channel 被移除了，看起来只能走通用 channel 的路径。具体想确认：

• 如果目标是路由到 Claude（Anthropic/Claude API），应该使用哪种 channel type / api_type？
• 之前 Claude Code 的特殊处理（prompt/路由/鉴权）被去掉后，现在推荐的配置方式是什么（例如 base_url + API key、OpenAI 兼容模式、自定义 headers 等）？
• 之前需要 OAuth / token 刷新才能跑通的能力，现在是否有等价替代？如果没有替代，是否意味着这条 “Claude Code” 路径目前处于不支持/不推荐状态？

我的目标是：在不依赖 Claude Code 专用 channel 的前提下，让同样的请求能够稳定工作。希望能给一个当前版本推荐配置的指引（哪怕是简短示例或相关文档链接也行）。非常感谢！🙏
