+            ### ⚠️ Invalid Pull Request title
+
+            Your PR title must follow the format: `type: Subject` where:
+            - `type` is one of the conventional commit types (in lowercase)
+            - `Subject` starts with an uppercase letter
 
-            It looks like your proposed **_Pull request title_** needs to be adjusted.

-            >🚩 **Error** » ${{ steps.lint_pr_title.outputs.error_message }}
+            #### Valid examples
 
-            #### Pull request title naming convention
+            - `feat: Add API endpoint for market data`
+            - `fix: Resolve WebSocket connection issues`
+            - `chore: Update NuGet dependencies`
 
-            Our PR title name taxonomy is `type: Subject`, where **type** is typically
-            *feat*, *fix*, or *chore*, and **subject** is a phrase (proper noun) that starts
-            with a capitalized letter.  The *chore* type usually has a subject that starts
-            with an action verb like *Add* or *Update*. Examples:
+            <details>
+            <summary>see more valid examples</summary>
