安全使用建议

This skill appears to be what it claims: a tiny CLI that downloads favicons via favicondl.com. Before installing or running scripts fetched from the internet, review the included favicondl.sh (it is bundled) to ensure it matches expectations. Prefer using the bundled file rather than blindly curl|sh from raw.githubusercontent.com. Note that requests to favicondl.com will reveal the domains you query to that service, and the script follows 302 redirects so the final downloaded file comes from the redirected URL — avoid saving to sensitive paths and don’t run as root. If you need higher assurance, inspect the upstream GitHub repo (https://github.com/sweesama/favicondl.com) and verify the script's integrity.

功能分析

Type: OpenClaw Skill Name: favicondl Version: 1.0.4 The skill is a legitimate utility designed to download website favicons using the favicondl.com API. The provided Bash script (favicondl.sh) and documentation (SKILL.md) are transparent, perform the stated functions without obfuscation, and contain no evidence of data exfiltration, malicious execution, or prompt injection attacks.

能力评估

✓ Purpose & Capability

The name/description match the included bash script and SKILL.md: both call favicondl.com to download favicons. No unrelated credentials, binaries, or config paths are requested.

ℹ Instruction Scope

Runtime instructions stay within the stated purpose (construct API URL, curl the endpoint, save file). The install instructions recommend downloading a script from a GitHub raw URL; that's common but worth noting because it directs users to execute remotely hosted code.

ℹ Install Mechanism

There is no formal install spec in the bundle (instruction-only), and the bundle includes the bash script. SKILL.md suggests installing by curl-ing a raw.githubusercontent.com URL. Using raw GitHub downloads to install scripts is common but carries the usual risk of executing remote code — prefer reviewing the included favicondl.sh before running.

✓ Credentials

No environment variables, credentials, or special config paths are requested; this is proportional for a simple network-fetching tool. The tool does make network requests to favicondl.com and follows redirects to the target site's assets (expected behavior).

✓ Persistence & Privilege

The skill does not request permanent presence (always:false) and does not modify other skills or system-wide configs. It only provides a small user-run script.

如何使用

确保已安装 OpenClaw（本地或 Docker 部署）
在对话框中输入安装命令：/install favicondl
安装完成后，直接呼叫该 Skill 的名称或使用 /favicondl 触发
根据 Skill 的参数说明提供必要输入，即可获得结构化输出
