 ### 更新
 
-Skill 有更新时，用 `--force` 覆盖本地已安装版本即可（不要重复执行无 `--force` 的 install）：
+Skill 有更新时，再执行一次安装即可（会直接覆盖本地已安装版本）：
 
 ```bash
-npx open-kimi-ppt-skills@latest install --force
+npx open-kimi-ppt-skills@latest install
 ```
 
 若当初用过 `--target`，更新时带上相同路径：
 
 ```bash
-npx open-kimi-ppt-skills@latest install --force --target ~/.claude/skills
+npx open-kimi-ppt-skills@latest install --target ~/.claude/skills
 ```
 
 也可以对 AI 说：`帮我更新 open-kimi-ppt skill`。更新只替换 Skill 文件，不会影响已生成的 PPTD / PPTX 项目。

 ### Update
 
-When the skill is updated, overwrite the local install with `--force` (do not keep re-running install without `--force`):
+When the skill is updated, run install again — it overwrites the local installation:
 
 ```bash
-npx open-kimi-ppt-skills@latest install --force
+npx open-kimi-ppt-skills@latest install
 ```
 
 If you originally installed with `--target`, pass the same path again:
 
 ```bash
-npx open-kimi-ppt-skills@latest install --force --target ~/.claude/skills
+npx open-kimi-ppt-skills@latest install --target ~/.claude/skills
 ```
 
 You can also ask your agent: `Update the open-kimi-ppt skill for me.` Updating only replaces the skill files; it does not touch PPTD / PPTX projects you already generated.
