The Agent Skills Directory

[COMMAND_EXECUTION]: The skill utilizes standard shell utilities like grep, cat, and ls to analyze project structure, detect CSS methodologies (e.g., BEM, CSS-in-JS), and verify configuration files like .browserslistrc. It also invokes npm run build to check for bundling errors.
[EXTERNAL_DOWNLOADS]: The skill uses npx to execute well-known development and auditing tools, including stylelint, lighthouse, webpack-bundle-analyzer, and axe-core. These tools are fetched from the official npm registry, which is a well-known and trusted service for development dependencies.
[REMOTE_CODE_EXECUTION]: Runtime execution is performed through standard package scripts (npm run build) and utility runners (npx). These are standard practices for frontend development and are used here for validation and diagnostics.
[PROMPT_INJECTION]: The skill interacts with project source code and configuration files. While reading external data creates a theoretical surface for indirect prompt injection, the skill's logic is restricted to diagnostic analysis of CSS patterns and does not involve executing instructions embedded within the CSS data.
