Description
透视变换可视化工具。根据用户指定的变换参数（平移/旋转/缩放/剪切/透视），修改网页初始配置并打开浏览器展示效果。适合教学演示和手动调试。
Usage Guidance
This appears to be a straightforward local/online HTML visualizer. Before using: (1) if you open the online demo (https://yu-zhengzheng.github.io/...), be aware any parameters encoded into a public URL could be visible to others; (2) when running locally, review index.html and the bundled three.min.js if you want extra assurance (three.min.js appears to be the standard Three.js bundle); (3) the skill does not request credentials, so it's safe from secret-exfiltration risks, but avoid blindly running unknown code that you haven't inspected if you require a high security posture. If you expect to open the visualizer on a remote device, note SKILL.md suggests encoding parameters into the URL or instructing the user to modify configData manually.
Capability Analysis
Type: OpenClaw Skill
Name: perspective-transform-visualizer
Version: 1.0.0
The skill bundle is a legitimate 3D perspective transformation visualization tool using Three.js. The instructions in SKILL.md correctly guide the AI agent to modify a local configuration object within index.html to visualize user-provided parameters. The code is transparent, lacks obfuscation, and contains no evidence of data exfiltration or malicious intent; it includes a standard third-party visitor counter (busuanzi.ibruce.info) which is common for static web projects.
Capability Tags
Capability Assessment
Purpose & Capability
Name/description match the included files (index.html, three.min.js, CSS) and SKILL.md. No unrelated env vars, binaries, or config paths are requested.
Instruction Scope
SKILL.md tells the agent to modify the index.html configData and open the page locally or use a listed online URL; it also suggests checking runtime channel/surface to choose local vs. online. These actions are appropriate for a visualizer and do not instruct reading unrelated files or secrets. (Note: SKILL.md references Start-Process which is a platform-specific way to open URLs/files.)
Install Mechanism
No install spec; this is instruction-only with static assets included. three.min.js is vendored locally (expected). No remote downloads or archive extraction occur during install.
Credentials
The skill requires no environment variables, credentials, or config paths. The only external endpoint referenced is an optional online demo URL for convenience — not required and not used to exfiltrate data by the skill files themselves.
Persistence & Privilege
always is false, the skill does not request persistent system privileges, nor does it attempt to modify other skills or system-wide settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install perspective-transform-visualizer - After installation, invoke the skill by name or use
/perspective-transform-visualizer - Provide required inputs per the skill's parameter spec and get structured output
Version History
