            const title = context.payload.pull_request.title;
            if (/^(feat|docs|fix|style|refactor|chore)\(.+?\)!?: /i.test(title)) return;
            const comment = `⚠️ PR 标题需以 \`feat(): \`, \`docs(): \`, \`fix(): \`, \`style(): \`, \`refactor(): \`, \`chore(): \` 其中之一开头，例如：\`feat(component): 新增功能\`。
            ⚠️ The PR title must start with \`feat(): \`, \`docs(): \`, \`fix(): \`, \`style(): \`, or \`refactor(): \`, \`chore(): \`. For example: \`feat(component): add new feature\`.

            如果跨多个组件，请使用主要组件作为前缀，并在标题中枚举、描述中说明。
            If it spans multiple components, use the main component as the prefix and enumerate in the title, describe in the body.

            如果是破坏性变更，请在类型后添加 \`!\`，例如 \`feat(component)!: 破坏性变更\`。
            For breaking changes, add \`!\` after the type, e.g., \`feat(component)!: breaking change\`.
