accessibilityExpertAnswer accessibility, a11y, and WCAG questions using BrowserStack's accessibility knowledge base.startAccessibilityScanStart an accessibility scan via BrowserStack and retrieve a local CSV report path.createAccessibilityAuthConfigCreate an authentication configuration for accessibility scans. Supports both form-based and basic authentication.getAccessibilityAuthConfigRetrieve an existing authentication configuration by ID. Requires the numeric id returned by createAccessibilityAuthConfig. No tool here lists existing configurations, so if you do not have the id, create one rather than guessing.fetchAccessibilityIssuesFetch accessibility issues from a completed scan with pagination support. Use cursor parameter to get subsequent pages of results. Requires the ids of a completed scan, which are returned by startAccessibilityScan. No tool here lists past scans, so if you do not have the ids, start a new scan rather than guessing.setupBrowserStackAutomateTestsSet up and run automated web-based tests on BrowserStack using the BrowserStack SDK. Use this tool for functional or integration test setup on BrowserStack only. For any visual testing or Percy integration, use the dedicated Percy setup tool. Example prompts: run this test on browserstack; set up this project for browserstack.percyVisualTestIntegrationAgentIntegrate Percy visual testing into new projects and demonstrate visual change detection through a step-by-step simulation. This tool handles initial Percy integration, setup, and creates a working demonstration for new users. Primary tool for prompts like: "Integrate percy for this project", "Integrate percy in this project {project_name}"expandPercyVisualTestingSet up or expand Percy visual testing configuration with comprehensive coverage for existing projects that might have Percy integrated. This supports both Percy Web Standalone and Percy Automate. Example prompts: Expand percy coverage for this project {project_name}addPercySnapshotCommandsAdds Percy snapshot commands to the specified test files.listTestFilesLists all test files for a given set of directories.runPercyScanRun a Percy visual test scan. Example prompts : Run this Percy build/scan. Never run percy scan/build without this toolfetchPercyChangesRetrieves and summarizes all visual changes detected by Percy AI between the latest and previous builds, helping quickly review what has changed in your project.- +40 more on the listing page
