 ## 通过 GitHub Action 进行代码审核

 当 PR 创建的时候会自动触发 Deepseek 代码审核，并将审核结果以评论的方式发布到对应的 PR 上。比如：[示例](https://github.com/hustcer/deepseek-review/pull/30) & [运行日志](https://github.com/hustcer/deepseek-review/actions/runs/13043609677/job/36390331791#step:2:53)
 
+### 当 PR 添加指定 Label 时触发审核
+
+如果你不希望创建 PR 时自动审核可以选择通过添加标签时触发代码审核，比如创建如下 Workflow：
+
+```yaml
+name: Code Review
+on:
+  pull_request_target:
+    types:
+      - labeled     # Triggers when a label is added to the PR
+
+# fix: GraphQL: Resource not accessible by integration (addComment) error
+permissions:
+  pull-requests: write
+
+jobs:
+  setup-deepseek-review:
+    runs-on: ubuntu-latest
+    name: Code Review
+    # Make sure the code review happens only when the PR has the label 'ai review'
+    if: contains(github.event.pull_request.labels.*.name, 'ai review')
+    steps:
+      - name: Deepseek Code Review
+        uses: hustcer/deepseek-review@v1
+        with:
+          chat-token: ${{ secrets.CHAT_TOKEN }}
+```
+
+如此以来当 PR 创建的时候不会自动触发 Deepseek 代码审核，只有你手工添加 `ai review` 标签的时候才会触发审核。
