# Slack Browser Automation (monomind:browse-slack)

Interact with Slack workspaces via browser automation — no API keys or OAuth required. Uses the existing web session.

See `monomind:browse` for the full browser automation reference. For API-based Slack integration, use the `mcp__claude_ai_Slack__*` tools instead.

## Quick Start

```bash
# Connect to existing Slack browser session
npx monomind browse open --port 0

# Or open Slack fresh
npx monomind browse open https://app.slack.com

# Take a snapshot to see what's available
npx monomind browse snapshot -i
```

## Core Loop

```
Connect/Open → Snapshot -i → Navigate → Extract/Interact → Screenshot
```

## Common Tasks

### Check Unread Messages

```bash
npx monomind browse open --port 0
npx monomind browse snapshot -i

# Navigate to Activity tab (all unreads in one view)
npx monomind browse click @e14        # Activity tab
npx monomind browse wait 1000
npx monomind browse screenshot activity-unreads.png

# Or expand "More unreads" in sidebar
npx monomind browse click @e21        # More unreads button
npx monomind browse wait 500
npx monomind browse snapshot -i
npx monomind browse screenshot unreads.png
```

### Navigate to a Channel

```bash
npx monomind browse snapshot -i
# Find channel name in sidebar (treeitem elements)
npx monomind browse click @e94        # example channel ref
npx monomind browse wait --load networkidle
npx monomind browse screenshot channel.png
```

### Search Slack

```bash
npx monomind browse snapshot -i
npx monomind browse click @e5         # Search button
npx monomind browse fill @e_search "keyword"
npx monomind browse press Enter
npx monomind browse wait --load networkidle
npx monomind browse screenshot search-results.png
```

### Extract Channel Info

```bash
npx monomind browse snapshot --json > slack-snapshot.json
# Parse for treeitem elements (channel names) and listitem elements (messages)
```

### Send a Message

```bash
npx monomind browse click @e_channel  # open channel
npx monomind browse wait --load networkidle
npx monomind browse snapshot -i
npx monomind browse fill @e_composer "Hello from monomind!"
npx monomind browse press Enter
npx monomind browse wait 1000
npx monomind browse screenshot sent.png
```

### Scroll Through Messages

```bash
npx monomind browse scroll down 500 --selector ".p-message_list"
npx monomind browse snapshot -i
```

## Sidebar Layout

```
- Threads / Huddles / Drafts
- [Section Headers]
  - [Channels as treeitems]
- Direct Messages
- Apps
- [More unreads] button
```

Key tabs to look for: `@e12` Home, `@e13` DMs, `@e14` Activity, `@e5` Search, `@e21` More unreads (refs vary by session — always snapshot first).

## Data Extraction

```bash
# Text content of a message or element
npx monomind browse get text @e_message

# Full structured snapshot for parsing
npx monomind browse snapshot --json > output.json
# Look for: treeitem (channels), listitem/document (messages), button (users), link (timestamps)

# Count unread items after expanding unreads
npx monomind browse snapshot -i | grep -c "treeitem"
```

## Best Practices

- Connect to existing sessions (`connect 9222`) — faster than opening a new browser
- Always `snapshot -i` before clicking — refs vary per session
- Re-snapshot after navigation — new page means new refs
- Use `snapshot --json` when you need to parse structured data
- Add `wait 1000` between rapid interactions to let Slack's React UI update
- Scroll sidebar if channel list is long: `scroll down 300 --selector ".p-sidebar"`

## Limitations

- No Slack API access — browser automation only (cookies, no bot tokens)
- Workspace-specific — no cross-workspace automation
- May be slower than API for high-volume reads

## Debugging

```bash
npx monomind browse console       # browser console messages
npx monomind browse errors        # uncaught JS exceptions
npx monomind browse get url       # current URL
npx monomind browse screenshot page-state.png
```

## Full Unread Check Script

```bash
#!/bin/bash
npx monomind browse open --port 0
npx monomind browse snapshot -i

# Activity tab
npx monomind browse click @e14
npx monomind browse wait 1000
npx monomind browse screenshot activity.png

# DMs tab
npx monomind browse click @e13
npx monomind browse wait 1000
npx monomind browse screenshot dms.png

# More unreads
npx monomind browse click @e21
npx monomind browse wait 500
npx monomind browse snapshot -i
npx monomind browse screenshot unreads.png

echo "See activity.png, dms.png, unreads.png"
```
