在 OpenClaw 中安装
/install web-perf
功能描述
Analyzes web performance using Chrome DevTools MCP. Measures Core Web Vitals (FCP, LCP, TBT, CLS, Speed Index), identifies render-blocking resources, network dependency chains, layout shifts, caching issues, and accessibility gaps. Use when asked to audit, profile, debug, or optimize page load performance, Lighthouse scores, or site speed.
安全使用建议
Install this if you want an agent to audit web page performance and inspect the relevant web project configuration. Review or pin the Chrome DevTools MCP package before using the suggested `npx -y ...@latest` command in sensitive environments, and avoid running the skill in repositories or browser sessions you do not want analyzed.
功能分析
Type: OpenClaw Skill
Name: web-perf
Version: 1.0.0
The skill is classified as suspicious primarily due to the 'Phase 5: Codebase Analysis' section in `SKILL.md`. This section instructs the AI agent to 'Search for configuration files' (e.g., `webpack.config.js`, `package.json`). While this action is plausibly related to web performance analysis, it implicitly instructs the agent to access and read local files. If the agent possesses file system access capabilities, this constitutes a high-risk behavior, even without clear malicious intent for exfiltration or unauthorized modification. Additionally, the `SKILL.md` recommends the user configure their environment by running `npx -y chrome-devtools-mcp@latest`, which introduces a supply chain risk as `npx -y` downloads and executes the latest version of a package without explicit confirmation, though this is a user setup instruction, not an agent action.
能力评估
Purpose & Capability
The stated purpose is web performance auditing with Chrome DevTools MCP, and the artifact's browser tracing, network request review, accessibility snapshot, and optional project configuration checks are aligned with that purpose.
Instruction Scope
The runtime instructions are bounded to auditing a target page and, when source access is available, inspecting web build configuration; there are no prompt overrides, hidden role changes, unrelated data access, mutation workflows, or exfiltration instructions.
Install Mechanism
The skill asks the user to configure a local MCP server with `npx -y chrome-devtools-mcp@latest`; this is disclosed and user-directed, but unpinned latest-package execution carries normal supply-chain risk.
Credentials
Reading package and bundler configuration files and using browser performance tooling are proportionate for a web performance audit, but users should run it only against repositories, sites, and browser sessions they intend to analyze.
Persistence & Privilege
The artifact contains no evidence of persistence, privilege escalation, background workers, credential harvesting, durable indexing, destructive actions, or automatic high-impact changes.
