A Claude Code skill for selling virtual/service-based offerings on 闲鱼 (Xianyu), Alibaba's second-hand marketplace. Covers the full operational stack from listing creation to traffic growth.

这是一个 Claude Code skill，帮助卖家在闲鱼平台从 0 开始做服务类目，覆盖选词、上架、定价、诊断、竞品分析等完整运营链路。

What it does

The skill activates whenever you mention Xianyu-related topics and switches into one of four operational modes based on what you need:

Mode	When to use	What you get
新品上架	Listing a new service	3 title variants · pricing recommendation · package structure · detail page copy framework · main image brief
商品优化	Low traffic or low conversion	Funnel diagnosis (where is it breaking?) · revised titles · specific fixes
账号运营	Account health and traffic growth	Cold-start roadmap · daily ops rhythm · cross-platform funnel
竞品分析	Analyzing a competitor's listing	Competitor profile · differentiation opportunities · actionable adjustments

Outputs are designed to be copied directly into Xianyu — no second-pass editing needed.

Algorithm claims are evidence-graded

All platform mechanism claims in this skill are sourced from Xianyu's official technical articles and algorithm disclosure documents, not operator folklore. Each claim carries a grade:

🔵 Official docs / official tech team publications
🟢 Empirical with data
🟡 Multi-person consensus, no hard data
🔴 Unverified / contradicted by available evidence

Common claims that are not supported by official sources include: video thumbnail traffic boost, "edit = new item boost", the 40/30/20/10 weight breakdown, and specific Zhima Credit thresholds. These are marked 🔴 and the skill does not recommend building strategy around them.

Installation

Claude Code

# From your project root, or wherever you keep skills:
git clone <this-repo-url>
# Then point Claude Code at the skill directory:
# Settings → Skills → Add → path/to/xianyu-service-ops

Or if you're using a .skill package file, drag it into Claude Code's skill panel.

Manual

Copy the xianyu-service-ops/ folder to your Claude Code skills directory and restart.

references/ files are loaded on demand — SKILL.md tells Claude when to consult each one. They don't inflate your context window on every invocation.

Companion skills (optional)

The skill mentions four companion skills that extend its capabilities when installed:

Skill	Purpose
`copywriting`	Deep-polish detail page copy (beyond the framework the skill produces)
`content-strategy`	Plan Xiaohongshu / Douyin content matrix to drive Xianyu traffic
`pricing-strategy`	Complex package design, Van Westendorp analysis
`seo-audit`	SEO for external landing pages (not Xianyu in-platform search)

These are optional. The skill works standalone — it will simply note when a companion skill would add value and describe what that skill would do.

Context persistence (optional)

Create .claude/xianyu-context.md in your project to save your account state. The skill reads this file at the start of each session and skips re-asking questions it already knows the answers to. Example:

# 我的闲鱼账号状态
- 服务类目：简历优化
- 账号状态：全新账号，0 评价
- 当前商品数：0
- 目标：先跑量，前 10 单快速拿评价
