Inspect production HTML for development comments, debug code, console logs, and temporary markup. Remove unnecessary remnants, check comments for sensitive information, and preserve comments needed for accessibility or legal purposes.
Use when reviewing templates, rendered HTML, or shared components related to Remove comments and debug code in production. Validate the final browser-facing markup, not just the source framework abstraction.
Review the instructions the agent will receive before you install.
Comments expose internal logic to attackers, increase file size, and can leak sensitive information like API endpoints, credentials, or system architecture.
Review this HTML code for unnecessary comments, debug code, console logs, and temporary markup that should be removed before production deployment.
Remove all development comments, debug code, unused markup, and temporary elements from the HTML before deploying to production.
Explain why cleaning up code before production is important for security, performance, and professional presentation of web applications.
Review templates, server-rendered HTML, and shared components that output markup related to Remove comments and debug code in production. Flag exact elements, attributes, and routes where the rendered HTML violates the rule.

Create and review custom 404 pages that help visitors recover from broken or moved links through search and navigation. Check the rendered page and HTTP response so missing content returns a proper 404 status.
Audit or create a dedicated About page that explains a website’s purpose and identifies its people or organization. Review the rendered output and supporting information, including expertise and contact details, to find gaps.
Review and add automated accessibility checks for components, pages, and continuous integration workflows. Use axe-based tools to detect structural and attribute issues, while identifying checks that still need keyboard or screen reader testing.
Review sign-in, registration, multi-factor authentication, and account recovery for accessibility barriers. Find blocked paste, difficult code entry, and inaccessible backup methods, then suggest authentication paths that support password managers, autofill, or device approval.
Review form errors, success messages, and live updates so screen reader users receive important notifications. Check the HTML delivered to the browser, announcement settings, display duration, and dismissal controls, then identify specific elements that need changes.
Review HTML tables so screen reader users can understand how headers and data relate. Check header markup, table descriptions, and merged cells, then identify specific fixes and ways to verify them.
