A tool for searching and checking items on Xianyu, also called Goofish, a Chinese secondhand marketplace. It uses the marketplace’s internal interface from a browser where the user is logged in.

Searching items, checking price trends, filtering by city or price, sorting results, viewing details, managing favorites, checking orders, and reviewing listed items.

It makes it easier to find listings and compare them using structured filters rather than browsing manually.

SkillSpector: 2 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Excessive Agency · line 29
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00175	$0.01764
Opus 5	$0.00088	$0.00882
Sonnet 5	$0.00035	$0.00353
Haiku 4.5	$0.00017	$0.00176

Security

Grade A, and why

xianyu-hub scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/alt_keywords.sh, scripts/detail.sh, scripts/ensure_tab.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Xianyu Search Skill (xianyu-hub)

Core Principle

In a browser tab where the user is already logged in to Xianyu, call Xianyu's internal API through minis-browser-use execute_js. The user must first log in to Xianyu in the built-in browser.

Startup Process (run before each use)

All scripts automatically call ensure_tab.sh to complete the following steps, so there is no need to manually pass --tab-id.

ensure_tab.sh Automatic Processing Logic

Scan all tabs - Parse the list_tabs text and look for a tab containing goofish.com
Check login state - Execute JS to determine whether the current page is logged in
Logged in -> Directly output tab_id, and the script continues
Not logged in -> Automatically execute:
- navigate to the Xianyu home page
- minis-open to open the built-in browser for the user to log in
- Poll the login state every 5 seconds, for up to 120 seconds; after login succeeds, automatically continue

To manually specify a tab, pass --tab-id <id>; the script will still verify the login state.

Script Overview

All scripts are located in /var/minis/skills/xianyu-hub/scripts/ and are run with sh.

1. Search Items - search.sh

sh scripts/search.sh -k <keyword> [options]

# Options:
#   -k <term>        Keyword (required)
#   -n <number>      Number per page (default 20, maximum 30)
#   -p <page>        Page number (default 1)
#   -s <sort>        default | price_asc | price_desc | time | reduce
#   --min-price <yuan>  Minimum price
#   --max-price <yuan>  Maximum price
#   --city <city>       City filter
#   --personal-only     Personal idle items only
#   -j              Output JSON

# Examples
sh scripts/search.sh -k "MacBook Air" -s price_asc --min-price 2000 -n 10
sh scripts/search.sh -k "iPhone15" --city Shanghai -s time

2. Item Details - detail.sh

sh scripts/detail.sh <itemID>

# Returns: title, price, description, views/wants/favorites count, seller information (positive feedback rate, response rate, number sold)

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
