The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill manages the installation and execution of the standard htmlhint package from the official npm registry.
Evidence: npm install --save-dev htmlhint and npx htmlhint commands listed in SKILL.md.
[COMMAND_EXECUTION]: The skill executes common command-line utilities for repository analysis and linting tasks.
Evidence: Uses rg (ripgrep) for searching file contents and npx to run the HTMLHint utility against local directories (dist/, wwwroot/) and remote URLs.
[PROMPT_INJECTION]: The skill identifies an attack surface for indirect prompt injection by processing external data from HTML files and live URLs.
Ingestion points: Local files matching *.html and external URLs passed as arguments to the linter.
Boundary markers: None present; the skill treats target HTML content as data for the linter.
Capability inventory: Shell command execution via npm, npx, and rg is available to the skill.
Sanitization: None; the skill relies on the underlying HTMLHint CLI tool to safely parse and validate the input content.
