+
+            One or more commit messages in this pull request do not follow the [Conventional Commits](https://www.conventionalcommits.org/) format.
+
+            ### Expected format:
+            \`\`\`
+            type(scope): description
+            \`\`\`
+
+            ### Valid types:
+            - **feat**: A new feature
+            - **fix**: A bug fix
+            - **docs**: Documentation only changes
+            - **style**: Changes that do not affect the meaning of the code
+            - **refactor**: A code change that neither fixes a bug nor adds a feature
+            - **test**: Adding missing tests or correcting existing tests
+            - **chore**: Changes to the build process or auxiliary tools
+            - **perf**: A code change that improves performance
+            - **ci**: Changes to CI configuration files and scripts
+            - **build**: Changes that affect the build system
+            - **revert**: Reverts a previous commit
+
+            ### Special commits (automatically allowed):
+            - Commits starting with **Merge**, **WIP**, or **Revert** are automatically skipped
+
+            ### Examples:
+            - \`feat(auth): add user authentication\`
+            - \`fix(api): resolve validation error in user endpoint\`
+            - \`docs: update API documentation\`
+
+            Please update your commit messages to follow this format. You can use \`git commit --amend\` for the latest commit or \`git rebase -i\` for multiple commits.
