# Connect to Slack
agent-browser connect 9222

# Take snapshot to locate unreads button
agent-browser snapshot -i

# Look for:
# - "More unreads" button (usually near top of sidebar)
# - "Unreads" toggle in Activity tab (shows unread count)
# - Channel names with badges/bold text indicating unreads

# Navigate to Activity tab to see all unreads in one view
agent-browser click @e14  # Activity tab (ref may vary)
agent-browser wait 1000

agent-browser click @e21  # More unreads button

agent-browser screenshot expanded-unreads.png

# Search for channel in sidebar or by name
agent-browser snapshot -i

# Look for channel name in the list (e.g., "engineering", "product-design")
# Click on the channel treeitem ref
agent-browser click @e94  # Example: engineering channel ref
# Replace `engineering` with the clicked channel's name so the old channel
# header cannot satisfy the wait while the new channel is still rendering.
agent-browser wait --fn "document.querySelector('[data-qa=\"channel_header\"]')?.innerText.includes('engineering')"

# Use Slack search
agent-browser snapshot -i
agent-browser click @e5  # Search button (typical ref)
agent-browser fill @e_search "keyword"
agent-browser press Enter
# Match the submitted query so a repeated search cannot reuse the old route.
agent-browser wait --fn "location.pathname.includes('/search') && new URL(location.href).searchParams.get('q') === 'keyword'"
