# Map Route Reader ## 产品定位 把“地图路线查询”变成更像结果型产品的 skill：不是只说个大概时间，而是尽量把真实路线读出来，整理成用户可以立刻参考的出行方案。 ## 一句话卖点 直接读取高德 / 百度地图上的真实路线结果，优先返回用户能照着走的公交、地铁、打车或步行方案。 ## 为什么更有下载欲望 很多同类路线能力看起来很强，但实际要： - 配 API - 补配置 - 自己拼接流程 - 最后还不一定能直接给出可走路线 这个 skill 主打的是： - **尽量直接可用** - **优先读真实地图结果** - **优先给可执行路线，不给空泛判断** - **用户问哪条线更好时，会真的把两条路线拉出来做对比** - **重点不是给模糊估计，而是给可直接拿去用的路线参考** ## 你装它，想得到的是什么 - 少一点“大概多久”的废话 - 多一点“从哪上车、哪换乘、哪下车”的真实结果 - 问打车 / 地铁 / 公交哪个更省事时，得到能直接参考的答案 Use this skill when the user asks for: - how to get from A to B - public transit routes - driving time - walking time - which station to transfer at - whether taxi is faster - whether a specific alternate route/line would be better - route comparisons such as “走 14 号线会不会更好” ## Goal Return a route the user can actually follow. Do not stop at vague estimates when a real route can be extracted. Priority: 1. exact route from a real map result 2. if the user proposes an alternate route/line, extract that route too and compare side by side 3. if exact route cannot be extracted, explain precisely where extraction failed and switch to the user-browser map tab via Browser Relay 4. only as a temporary fallback, give a clearly-labeled estimate ## Preferred workflow ### 0) For Amap, prefer `uriapi` route pages with `lnglat` when coordinates are available If you can get origin/destination coordinates, prefer opening a direct Amap route URL like: `https://ditu.amap.com/dir?type=bus&policy=2&from[lnglat]=<lng,lat>&from[name]=...&to[lnglat]=<lng,lat>&to[name]=...&src=uriapi&innersrc=uriapi&dateTime=now` Why: - this bypasses wrong default city context - the route card often renders directly in page text - total duration / walking distance / fare / line names can often be extracted from `document.body.innerText` ### 1) Try normal read first - Use browser on public map pages first. - Prefer Amap or Baidu Maps for China routes. - Try direct route pages with origin/destination query params. - If the page exposes the full route card, extract: - total time - total walking time if visible - number of transfers - station names / line names - final arrival station or walking segment ### 1.5) On Amap route pages, extract hidden detail siblings After the recommended route card renders, the full step-by-step transit detail may exist in the hidden sibling node right after the current `.planTitle` (for example an `ol.p_route`). Do not stop at total duration. Read that hidden detail block and extract: - walking segment distance and minutes - line name and direction - boarding station and exit/gate info - number of stops - transfer station - alighting station and exit number - final walking segment to destination - approximate duration of each transit segment when the page exposes enough information to infer it ### 2) If the map page needs interaction If the site asks to confirm the start/end place, or the route card is hidden behind dynamic UI: - keep using browser - interact to confirm the correct start/end point - prefer the first recommended public transit route unless the user asked for fastest/least walking/least transfers ### 3) For China map sites, prefer the user's real map tab when city context matters For Amap/Baidu route pages, the isolated browser may resolve the wrong city or fail to expand the route card. If the page shows the wrong city, cannot resolve start/end places, or keeps asking to choose the correct place, switch early to the user's map tab via Browser Relay and read the live route result there. ### 4) If normal browser still cannot read the real route Switch to the user’s browser tab via Browser Relay. - Ask the user to open the target map route page in Chrome. - Ask them to click Browser Relay on the exact map tab. - Then read the real route card from that tab. ## Comparison rule If the user asks whether a specific route/line would be better, for example: - “走 14 号线会不会更好” - “打车会不会更方便” - “xx 这么走是不是更好” then you must: 1. keep the current recommended route 2. extract the user-specified route too 3. present a side-by-side comparison Do not guess. Do not answer from intuition alone. Do not say “应该不会” or “大概率更慢” unless the alternate route has been pulled out and compared. ## Output format For a single route, return in this structure: - 起点：... - 终点：... - 方式：公交 / 地铁 / 打车 / 步行 - 预计总时长：... - 推荐路线：... - 换乘：... - 每段步骤：... - 下车后：... - 备注：如有不确定，明确写出来 If route detail is available, include: - 上车站 - 下车站 - 换乘站 - 出口 - 每段步行距离与时间 - 每段乘车站数 - 每段乘车大约多久 For a route comparison, return side-by-side: - 方案 A - 方案 B - 总时长 - 步行距离 - 换乘次数 - 线路结构 - 哪个更快 / 哪个更省事 / 哪个更少走路 ## Rules - Do not stop at “I’ll check” or “probably around ...” unless exact extraction has genuinely failed. - If exact extraction failed, say which step failed. - For map queries, a user-visible answer should try to be route-usable. - If the user corrected the place name, restart from the corrected place immediately. - If the user corrected the place name, never reuse the old route result as if it applied to the corrected place. - For comparison questions, do not brain-fill the alternate route. Pull it out, then compare.
