…elisted agents
Kimi Coding Plan (api.kimi.com/coding/v1) enforces a strict User-Agent
whitelist. Verified via curl testing:
- ✅ whitelisted: claude-cli/*, claude-code/*, Kilo-Code/*
- ❌ rejected: codex-cli/*, kimi-cli/*, openclaw/*
This fix injects a whitelisted User-Agent (claude-cli/{version}) for
all requests to Kimi endpoints when the original agent (Codex, OpenCode,
Gemini, Hermes, OpenClaw) is not on the whitelist.
Claude Code retains its original claude-cli/{version} UA since it is
already whitelisted.
Fixes 403 Forbidden: 'Kimi For Coding is currently only available for
Coding Agents such as Kimi CLI, Claude Code, Roo Code, Kilo Code, etc.'

期待合入 支持 kimi code plan |

Would it also be possible to add a feature to Claude Code that allows modifying the User-Agent? The reason I ask is that some relay services only accept Codex's User-Agent when running GPT models, and only accept Claude CLI's User-Agent when using Claude models. This means that every time I switch models, I have to switch to a different CLI as well, and I lose all my conversation history in the process. It would be really helpful if Claude Code could support custom User-Agents. |

Hi @farion1231, this PR has passed all CI checks and Codex review without any major issues. Could you please take a look when you have a moment? Thanks! 🙏 |
|
Hope to speed up the progress |
等不及了 |
期待合并，不理解 kimi 的风控逻辑，为了防中转站使用 kimi for coding 就只从 UA 识别一刀切了其他 Agent 使用的可能吗，就没有更好的方式了吗，而且这种伪造 UA 的方式是 work 的 |
|
我使用某些api中转站时也有自定义请求头的需求, 不应该只因为 kimi 的风控政策影响其它中转站的使用 |
…ettings Polish the provider-level User-Agent override UI on the Claude and Codex forms. - Add a shared CustomUserAgentField (label + input + preset dropdown + live validation) so both forms stay in sync. - Provide curated UA presets (Claude Code / Kilo Code families that pass coding-plan UA whitelists per #3671); the first is Claude Code's real `claude-cli/x (external, cli)` format. Whitelists gate on the name prefix, not the version, so static values stay valid across upgrades. - Expose presets via a dropdown to the right of the input (z-[200] so it renders above the dialog layers) instead of inline chips. - Move the field into the existing advanced/reasoning collapsibles. - userAgent.ts mirrors the backend byte rule (reject only control chars; non-ASCII is allowed) for a non-blocking inline hint. - i18n for all four locales (zh/en/ja/zh-TW).

新版本已经支持了自定义请求头了 Kimi 可以接入了 |
我使用内置的那个选项还是会报错 |
|
这个报错应该是没有开启路由接管吧？直接请求了 kimi 的 response 接口，这个接口是不存在的
