Paper 选题澄清命令（选题导航器）。当用户只有模糊研究方向、说不清要研究什么、想把兴趣聚焦成研究问题（RQ），或已有一个候选题想被检验，或说选题、开题方向、不知道研究什么、帮我想想研究什么、你看这个题行不行、给我几个这个方向常见的研究问题、paper-topic 时使用——即使只说"我想研究 AI 和教育但不知道具体做什么"或"我想研究 X，你看这个题行不行"也应使用。行为铁律：一步步引导、逐层给选项（选项装该方向学界客观常见的研究问题 / 拆解维度，摆事实、不推荐不排序不打分，每组固定带末项"以上都不是，我自己说"）、每一步用户拍板（选一个 / 都不要、自己给，可全弃自填）、逐层收敛出用户拍板的最终 RQ 后产 HTML 报告（只罗列过程、摆事实、不下结论）；系统绝不给正确答案、绝不推荐"研究哪个更好"、绝不排序打分、绝不替用户成句定稿；"替我推荐 / 排序 / 挑一个最好的 / 直接帮我写"走三段式转化，"给我该方向常见的研究问题参考"是正常能力、不拦。

carinyadigital Bundle

Use when the user wants to change how existing UI looks or behaves — fix spacing, colour, layout, states, responsiveness, or accessibility on a component, page, or flow. Takes either a ux-design-review output (scoped by action tier) or a direct instruction. Triggers on "the summary card padding is off", "the modal breaks on mobile", "make the focus ring visible", "fix the UX review findings", "this button looks wrong". Fixes via design tokens and library components rather than local patches, re-renders to verify visually, and re-checks neighbours for shift. Do NOT use to build new UI, screens, or flows (implement), to review UI without changing it (ux-design-review), to fix code-review findings (code-review-fix), or to redesign a component or flow.

Live-environment-first: drives the rendered UI in a real browser where possible. Works with any framework or design tooling. Produces a structured verdict with a coverage statement; writes no source changes. Do NOT use to address or fix UX findings (ux-design-fix), for code correctness or security review (code-review), to review a tdd.md document (docs-review), or to implement features (implement).
