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.

Security

Grade B, and why

macos-setup scanned grade B with 2 findings 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 7d ago.

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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Skill Capabilities

0. Network Proxy Check (前置步骤)

在开始安装前,必须确保网络可以访问 Google 和 GitHub:

check_network() {
    echo "=== Network Connectivity Check ==="
    echo ""

    # Test GitHub
    echo "Testing GitHub..."
    if curl -s --connect-timeout 5 https://github.com > /dev/null 2>&1; then
        echo "✅ GitHub: accessible"
    else
        echo "❌ GitHub: not accessible"
        NEED_PROXY=true
    fi

    # Test Google (for some Homebrew dependencies)
    echo "Testing Google..."
    if curl -s --connect-timeout 5 https://www.google.com > /dev/null 2>&1; then
        echo "✅ Google: accessible"
    else
        echo "❌ Google: not accessible"
        NEED_PROXY=true
    fi

    # Test Homebrew
    echo "Testing Homebrew..."
    if curl -s --connect-timeout 5 https://raw.githubusercontent.com > /dev/null 2>&1; then
        echo "✅ Homebrew sources: accessible"
    else
        echo "❌ Homebrew sources: not accessible"
        NEED_PROXY=true
    fi

    if [ "$NEED_PROXY" = true ]; then
        echo ""
        echo "⚠️  Network issues detected. Proxy configuration required."
        return 1
    fi

    echo ""
    echo "✅ Network OK - Ready to proceed"
    return 0
}

代理配置流程:

  1. 询问用户代理信息:
questions:
  - id: proxy_needed
    question: "Do you need to configure a network proxy to access GitHub/Google?"
    options:
      - label: "Yes, I have a proxy"
        description: "Configure HTTP/HTTPS proxy"
      - label: "No, direct connection works"
        description: "Skip proxy configuration"

  - id: proxy_config
    question: "Please provide your proxy configuration:"
    condition: "proxy_needed == 'Yes'"
    inputs:
      - label: "Proxy URL"
        placeholder: "http://127.0.0.1:7890"
        example: "http://127.0.0.1:7890 or socks5://127.0.0.1:1080"

Files

What ships with it

2 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.
