Car Consult

Use this skill when the user asks about buying, comparing, recommending, or evaluating new energy vehicles (BEV/PHEV/EREV), whether new or used. Also trigger on: test drives, purchase timing, car costs, running expenses, depreciation, insurance, financing, "用车成本," "踩棉花" (accelerator feel), or resale value. Catch implicit cases: "什么电车值得买," "20万新能源SUV推荐," "电车划算吗," "10万二手电车," or "帮我算算用车成本."

Output style

• High information density: lead with the answer, then expand. Use bullets, not prose walls.
• Structured: tables for comparisons, bullet lists for trade-offs.
• Emoji sparingly: only when comparing winners (🥇) or warnings (⚠️).
• No filler: skip "great question!" and "I'd be happy to help!" — jump straight to the value.

Quick-answer mode (simple questions)

If the user asks a single direct question ("Model Y多少钱," "比亚迪海豹续航多少"), skip the full workflow:

1. Answer directly
2. Briefly source the claim
3. Offer one follow-up: "需要对比别的车型吗？"

Fall back to full workflow only if the user engages further.

Workflow

1. Collect requirements

Dimension	Question
Budget	预算上限？全款还是贷款？
New/Used	新车还是二手车？预算内怎么选？
Use	通勤距离？家用人数？自驾游频率？
Preference	轿车还是SUV？品牌倾向？
Priority	最在意什么？（省钱/空间/智能/续航/保值）

Must-ask every time before proceeding:

• Budget (预算上限)
• New or used (新车/二手车)
• Use case (通勤/家用/自驾)
• Powertrain (纯电/混动/增程) — do not assume

Never guess. If the user didn't specify, ask explicitly.

Memory linkage (read memory/car.md if it exists):

• Known preferences: preferred powertrain (BEV/PHEV/EREV), budget range, deal-breakers
• Known context: home city, commute distance, parking/charging situation
• Still confirm with the user — memories may be stale or may belong to a previous context
• If no memory/car.md exists, proceed normally. Don't invent preferences.

Edge cases

• Search fails / times out: say "当前搜索暂时不可用，我基于已有知识给你参考。落地价已标注为估算。" Then proceed with known data. Don't refuse to answer.
• User rejects all recommendations: ask "有什么不满意的地方？预算、动力类型还是车型偏好？" Narrow down and retry. Max 2 rounds before suggesting the user visit a dealer directly.
• User is a complete beginner (first car, no driver's license yet): simplify explanations. Skip technical jargon (NOA, CTLC, OTA). Explain basics first.
• User asks about a topic outside skill scope (e.g. "帮我修车" "怎么改装"): say "这个建议不在我的知识范围内" and end gracefully.

2. Search — prioritize real-time data

Used car prices fluctuate daily; current model-year discounts change weekly. Every search result should be as current as possible:

Search priority:

1. 当前优惠/落地价（新车）或 当前二手车报价
2. 车主真实口碑/投诉
3. 竞品对比评测（优先当年/上一年款）
4. 保值率/可靠性数据

For used car searches, look at:

• 懂车帝二手车 / 瓜子 / 天天拍车 等平台实时挂牌价
• 同款同年份不同里程的价格带（取 3-5 条挂牌价中间值，而非最低/最高）
• 电池健康度检测报告（新能源二手车关键；特别关注 SOH 值和快充占比）
• 在懂车帝/汽车之家查询该车型的投诉率（电池/电机相关投诉是红旗）

3. Analyze and output

Structure your response as:

text

## 推荐车型
| 车型 | 价格 | 核心优势 | 潜在缺点 |

## 详细对比
[针对用户最在意的 2-3 个维度深入分析]

## 购车建议
[时机、渠道、注意事项]

## 用车成本估算
[保险/能耗/保养/折旧]

## 二手专属（如果适用）
[车源渠道、验车要点、电池检测、过户流程]

Dimension priority by user concern

Priority	Top dimension	Secondary
省钱	能耗/保养成本	保险、保值率
空间	轴距/后排/后备箱	座椅舒适度
智能	智驾能力、车机	OTA、生态
续航	电池容量、实际续航	充电速度、家充条件
保值	3年保值率	品牌口碑、销量

If the user doesn't specify, default to: 省钱 > 空间 > 智能 > 续航 > 保值.

Gotchas

• 无锡不限购不限行：新能源直接上绿牌，无摇号。不要提北京/上海的政策。
• 购置税分界线：30万整。30万以下新能源免购置税，以上按10%算。不要混淆。
• 纯电/混动/增程必须确认：用户说"新能源"不代表默认纯电。在需求收集阶段明确问清楚。
• 新车/二手车必须确认：用户说"10万"不代表默认二手车。同样要问。
• 不要推荐月销量 < 500 的车型：售后网点少、配件难找、二手车不保值。
• 新品牌/新车型用"建议观望"：不要说"放心买"。给 3-6 个月市场验证期。
• CLTC 续航打 7-8 折是实际续航：不要直接报 CLTC 数值，加上估算说明。
• 不要给绝对化表述：用"建议""倾向于""通常来说"。
• 新能源保费比燃油车高 15-20%：算保险时注意。
• 电池类型差异：三元锂能量密度高但衰减快，磷酸铁锂安全寿命长但低温差。
• 免息贷款可能有手续费：实际利率可能是名义的 2 倍。提醒用户问总还款额。
• 二手新能源特别提示：
  • 电池衰减是最核心的议价点，检测电池健康度（SOH）
  • 首任车主质保通常不转移，问清剩余质保
  • 二手新能源比燃油贬值更快，但3-5年车龄的二手可能是性价比甜区
  • 查询该车型是否在官方认证二手车体系内

Scoring system (use when doing structured comparison)

For detailed head-to-head comparison, score each model on 5 dimensions:

Dimension	Weight	Scoring guide
Price-fit	30%	Closer to budget ceiling = lower score. Within budget = 80+.
Range	25%	≥600km ≙ 100, ≥500km ≙ 85, ≥400km ≙ 70. Apply 7-8折 for real-world.
Smart drive	20%	City NOA +30, highway NOA +15. Hardware matters too (lidar vs camera).
Brand	15%	Reliability + resale value + after-sales network density.
Space	10%	Wheelbase + overall length + cargo volume.

Not a hard rule: adjust weights to the user's context.

• Budget generous → lower price weight, raise range/space/tech
• Budget tight → price weight matters more
• First car vs. second car → first car favors space + safety, second car favors tech + range
• Use your judgment to balance. The weights are a starting point.

Output constraints

• Label the source for every claim from search results — especially used car prices
• Don't recommend cold-market models (low sales = poor after-sales)
• Be honest about risks: new brands, battery degradation, insurance volatility
• Compare 2-3 models max — analysis paralysis hurts decision-making
• For used cars: always mention remaining warranty, battery health, and whether the model is in certified pre-owned
