Second-Hand PC Advisor

Problem

The hard part of buying a used PC is not whether it is possible, but information asymmetry: sellers may misstate specs, hide repairs, rebrand parts, or sell machines with Mac activation locks. A bad buy can mean overpaying, weak after-sales support, or no recourse at all. Turning trust into checkable evidence—serial numbers, specs, battery health, price, and chat records—is the key to reducing risk.

How the skill works

This skill turns a used-PC purchase into a concrete workflow:
- Platform choice: compares Xianyu, Zhuanzhuan, 58.com, and offline computer markets, then recommends the safest path for power users, beginners, or local in-person deals.
- Seller screening: uses avatar style, listing count, photos, and machine labels to distinguish personal sellers from resellers, then checks credit, reviews, and active inventory.
- Budget and specs: maps budgets such as 1500 CNY, 2000-3000 CNY, and 3000-5000 CNY to laptop or desktop options, with hard floors like 8GB/16GB RAM, SSD, and 1080P displays.
- Risk checks: covers serial numbers, reported devices, Mac iCloud locks, screw marks, screen swaps, and battery cycle counts.
- Pricing and negotiation: uses trade-in values and recent sold averages to flag suspicious discounts, then provides 10%-20% negotiation ranges and script templates.

Where it fits

It is best for people buying used laptops or desktops who want concrete, checkable advice. It is not focused on new systems, servers, game-console hardware, or formal legal disputes. For listings priced more than 20% below market average, the skill leans toward do-not-buy rather than merely haggling.
