Common Tasks

Verify Page Loads Correctly

1. Navigate to /features/browser-mcp
2. Verify hero heading "Talk to AI. Control any website." is visible
3. Verify browser mockup #mcp-hero-browser renders with sender info
4. Scroll down and verify all 7 sections are present
5. Check that run log screenshot loads (no broken image)

Verify Hero Animation Cycle

1. Observe hero mockup for first conversation (Mike Chen, SRE)
2. Wait for Draft Reply button to show "Analyzing..." then "Drafting..."
3. Verify text types into textarea character by character
4. Verify button changes to green "Done" state
5. Wait 3500ms for next conversation (Rachel Torres, AE)
6. Verify name, role, avatar, and messages all update
7. Wait for full cycle back to Mike Chen (3 conversations total)

Test Config Tab Switching

1. Scroll to "Quick Setup" section
2. Verify Claude Code tab is active by default (bg-slate-800 + border-primary)
3. Verify config shows claude_desktop_config.json filename
4. Click "Cursor" tab button
5. Verify Cursor tab becomes active, Claude Code tab becomes inactive
6. Verify config shows .cursor/mcp.json filename
7. Click "Windsurf" tab and verify ~/.codeium/windsurf/mcp_config.json

Test Config Copy Functionality

1. Scroll to Quick Setup section
2. Click the "Copy" button for the active tab
3. Verify button text changes to "Copied!" with primary color
4. Wait 2000ms and verify button reverts to "Copy"
5. Verify clipboard contains valid JSON with mcpServers.sidebutton config

Verify All Links Work

1. Check hero "Install Free Extension" links to Chrome Web Store URL
2. Check hero "Setup Guide" links to docs.sidebutton.com/mcp-setup
3. Check Related Features: /features/chat, /features/ai-automation, /integrations
4. Check CTA "Get Started Free" links to docs installation page
5. Check CTA "View AI Automation" links to /features/ai-automation

Verify Responsive Layout

1. Resize viewport to mobile (375px width)
2. Verify architecture diagram arrows change from horizontal to vertical
3. Verify MCP tools grid collapses to single column
4. Verify config tabs remain accessible
5. Resize to tablet (768px) and verify 2-column grids
6. Resize to desktop (1280px+) and verify annotation label appears

Tips

• The hero animation uses IntersectionObserver (threshold 0.3) and visibilitychange — it only runs when the mockup is visible on screen and the tab is active
• Hero conversations cycle through 3 personas: Mike Chen (SRE @ Dataflow), Rachel Torres (AE @ CloudScale), James Wilson (Support Lead @ FinServe) — all replies are approximately 75 characters to avoid layout shifts
• The typing animation calculates per-character delay as TYPING_TOTAL / reply.length for consistent total duration
• Cursor position is calculated using a hidden canvas measureText for accurate placement
• All 3 config tab JSON contents are identical (npx @sidebutton/mcp) — only the filename differs
• Copy buttons use navigator.clipboard.writeText which requires secure context (HTTPS or localhost)
• The architecture diagram uses flex-col md:flex-row so the layout is vertical on mobile, horizontal on desktop
• BrowserMcpHero is a standalone component (not using the shared FeatureHero) with its own scoped styles and inline script

Gotchas

• Hero animation timing is sequential: Each phase depends on the previous completing — interrupting (scrolling away, tab switch) resets the entire animation to the beginning of the current conversation
• Reduced motion completely changes behavior: With prefers-reduced-motion: reduce, all CSS animations are disabled and the Draft Reply button becomes a manual click trigger that shows the reply instantly
• Annotation only visible at 1280px+: The "One-click automation" floating label uses display: none by default, only display: flex at min-width: 1280px — tests at smaller viewports will never see it
• Copy button requires clipboard API: navigator.clipboard.writeText fails silently in non-secure contexts — the catch block logs to console but shows no user-facing error
• Config tab state is DOM-based: Tab switching uses classList.add/remove not framework state — a snapshot after tab click will show the new state immediately
• Run log screenshot is lazy-loaded: The loading="lazy" attribute means the image may not be loaded when you first scroll to the section — wait or scroll past it to trigger load
