Identify and test critical workflows where APIs, services, databases, and interface components work together. Review normal behavior, important failures, and CI checks to find gaps that isolated unit tests can miss and keep those interactions continuously verified.
Use when reviewing CI coverage, automated checks, or test strategy related to Write integration tests for key workflows. Focus on whether the rule is continuously verified, not just documented.
Review the instructions the agent will receive before you install.
Unit tests verify individual functions in isolation, but they can't catch the bugs that occur when those functions interact — a perfectly correct validation function and a correct database function can still fail when wired together incorrectly. Integration tests catch these wiring bugs before they reach production, where they're expensive to diagnose.
Identify the key integration points in this codebase — where API routes call services, where services interact with the database, and where components interact with state management. Are these tested?
Write integration tests for the identified critical paths, testing the interactions between components rather than each in isolation.
Explain integration testing, how it differs from unit and E2E testing, and what tools to use for API and component integration tests.
Review tests, CI workflows, and enforcement points related to Write integration tests for key workflows. Flag exact gaps where the rule is not automatically verified or where failures do not block regressions.

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.
