 ## What is CCG
 
-In short: **Claude Code directs Codex and Gemini to write code for you.**
+In short: **Codex and Gemini analyze. Claude writes the code. Fully transparent.**

-You describe what you want. CCG figures out who should handle it. The result goes through Claude's review before touching any file. Codex and Gemini never write directly to your codebase.
+**The key point**: by default, Claude is the one writing code — not a black box. You see the full process in Claude Code. Codex and Gemini are "advisors" that never directly touch your files.
+
+There's also **codex-exec mode**: Codex writes the code instead, then Claude + Gemini do multi-model cross-review. Good for well-defined tasks with lower token cost. See [Workflow Guide](/en/guide/workflows).

 ## CCG 是什么

-你发一条需求，CCG 判断该给谁干，干完了 Claude 审核，没问题才写入代码。Codex 和 Gemini 全程碰不到你的文件。
+**关键点**：默认模式下最终写代码的是 Claude，不是黑盒——你在 Claude Code 里能看到完整的改动过程。Codex 和 Gemini 是"参谋"，不直接碰你的文件。
+
+还有一种 **codex-exec 模式**：让 Codex 来写代码，写完后 Claude + Gemini 多模型交叉审查。适合目标明确的任务，token 消耗更低。详见[工作流指南](/guide/workflows)。
