安全使用建议
This skill appears to be what it claims: a collection of JavaScript snippets meant to run inside a page via Chrome DevTools to measure LCP, CLS, INP and related diagnostics. Before you run it, consider: 1) these snippets execute in the page context and will read performance entries and resource URLs/timings (they do not contain network exfiltration code), 2) they add outlines and observers and expose window functions (which may remain active in the page until the page is reloaded), and 3) cross-skill references mean deeper workflows may call other snippet sets — review/trust those other skills before using them on sensitive pages. If you have sensitive/secure sessions (banking, auth flows), run the snippets on a staging copy or non-sensitive page first. If you want higher assurance, review the repository link in SKILL.md (https://github.com/nucliweb/webperf-snippets) to confirm source integrity and recent commits.
功能分析
Type: OpenClaw Skill
Name: webperf-core-web-vitals
Version: 0.1.0
The bundle is a legitimate collection of web performance diagnostic tools designed for use with Chrome DevTools. The JavaScript snippets (e.g., CLS.js, INP.js, LCP.js) utilize standard browser Performance APIs to measure Core Web Vitals and provide structured feedback to the AI agent. The SKILL.md file contains logical workflows and decision trees for performance auditing without any evidence of prompt injection attacks, data exfiltration, or malicious intent.
能力评估
Purpose & Capability
Name/description promise (LCP, CLS, INP analysis and decision tree) lines up with the provided JS snippets and SKILL.md instructions that tell the agent to run those snippets in Chrome DevTools. No unrelated environment variables, binaries, or install steps are requested.
Instruction Scope
SKILL.md instructs the agent to evaluate the provided scripts via the chrome-devtools MCP and capture results. The scripts operate on performance APIs, DOM, and set PerformanceObservers and window helper functions (e.g., getINP). This is expected for in-page diagnostics, but note the scripts modify page DOM (outline styling) and register observers/globals that persist for the page lifetime.
Install Mechanism
No install spec is present (instruction-only skill with included JS snippets). No downloads or package installs are performed by the skill manifest itself.
Credentials
The skill declares no environment variables, no credentials, and no config paths. All required capabilities are limited to in-browser APIs and are proportional to the stated purpose.
Persistence & Privilege
always:false and normal model-invocation behavior. The only persistence is in-page: the scripts register observers and sometimes expose window functions to fetch tracked results. They do not modify agent or system-wide settings or request permanent platform presence.
