Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00064 | $0.04705 |
| Opus 5 | $0.00032 | $0.02353 |
| Sonnet 5 | $0.00013 | $0.00941 |
| Haiku 4.5 | $0.00006 | $0.00470 |
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.

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

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:
- 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"
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.
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.

macos-setup is a skill published in the GitHub repository julianobarbosa/claude-code-skills (10 stars, last pushed 12d ago), licensed MIT. It adds 64 tokens to every session and 4,705 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
