加密货币雷达

数字货币行情监控工具。当用户询问「比特币」「以太坊」「BTC」「ETH」「数字货币行情」「加密货币」「Crypto」「比特币价格」「以太坊价格」时使用。使用 Yahoo Finance（实时价格）和 CoinGecko（市值/交易量）双数据源。

Security Scan

The skill's code and instructions match its stated purpose (fetching crypto prices from Yahoo Finance and CoinGecko), request no credentials, and contain no obvious exfiltration or unrelated capabilities.

Purpose & Capability

Name/description promise (crypto market monitoring using Yahoo Finance + CoinGecko) matches the included Python script and SKILL.md. The script only calls the two described public APIs and computes basic ratios; no unrelated services or credentials are requested.

Instruction Scope

SKILL.md and the script stay within the monitoring/analysis scope and only perform network requests to Yahoo Finance and CoinGecko and print results. Minor note: the SKILL.md quick-run example uses a hard-coded user workspace path (C:\Users\gold3\...), which is a developer-specific example and not required for operation—this could confuse users but is not a security issue. The instructions do not ask the agent to read other files, env vars, or send data to unexpected endpoints.

Install Mechanism

There is no install spec (instruction-only with a small Python script). Nothing is downloaded or installed by the skill itself; it relies on standard Python and the requests library being available.

Credentials

The skill requires no environment variables or credentials and uses public REST endpoints with no API keys. No broad or unrelated secrets are requested.

Persistence & Privilege

always is false and the skill does not request permanent presence or modify other skills/configs. disable-model-invocation is false (normal), allowing autonomous invocation which is expected for skills; this does not combine with other red flags.

Assessment

This skill is internally consistent with its stated purpose: it fetches public crypto data from Yahoo Finance and CoinGecko and prints analysis. Before installing, consider: 1) the skill makes outbound network calls to those public APIs (ensure that's acceptable in your environment and be aware of rate limits); 2) the SKILL.md contains a developer-specific example path (C:\Users\gold3\...)—ignore or adjust that when running; 3) review the included script if you need to restrict which symbols are queried or to add timeouts/logging; and 4) since it can be invoked autonomously (normal default), ensure you’re comfortable with the agent making these harmless network requests on your behalf.

数据获取

Yahoo Finance（实时价格）

import requests

def get_crypto_price(symbol):
    url = f"https://query2.finance.yahoo.com/v8/finance/chart/{symbol}-USD?interval=1d&range=1d"
    headers = {"User-Agent": "Mozilla/5.0"}
    r = requests.get(url, headers=headers, timeout=10)
    meta = r.json()["chart"]["result"][0]["meta"]
    price = meta["regularMarketPrice"]
    prev = meta["chartPreviousClose"]
    chg = price - prev
    pct = chg / prev * 100
    return {"price": price, "chg": chg, "pct": pct}

CoinGecko（市值 + 24h 交易量）

import requests

def get_crypto_markets():
    ids = "bitcoin,ethereum,solana,binancecoin,ripple,cardano,dogecoin"
    url = f"https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&ids={ids}&order=market_cap_desc&per_page=10&sparkline=false&price_change_percentage=24h"
    r = requests.get(url, headers={"User-Agent": "Mozilla/5.0"}, timeout=10)
    return r.json()
    # 返回: price, market_cap, total_volume, price_change_percentage_24h

情报解读框架

指标	信号
BTC 市占率 > 55%	避险情绪，主流资金抱团
BTC 市占率 < 45%	Alt Season（山寨季）
ETH/BTC 比值 < 0.030	ETH 相对 BTC 弱势
ETH/BTC 比值 > 0.050	ETH 强势，可能有 Alt Season
山寨币涨幅 > BTC 3倍	资金外溢，风险偏好上升
全市场市值 vs BTC	判断整体趋势方向

关键比值：

• ETH/BTC ratio：以太坊相对比特币强弱
• BTC Dominance：比特币市值占全市场比例
• 山寨季指数：全市场 vs BTC 的涨跌对比

分析顺序：

1. BTC 价格 + 市占率（方向）
2. ETH 价格 + ETH/BTC 比值（Alt 风向标）
3. 主流山寨（SOL/XRP/DOGE）— 情绪扩散
4. 全市场市值变化（判断趋势是否延续）
