What it does

Interact with Slack workspaces using browser automation. Use when the user needs to check unread channels, navigate Slack, send messages, extract data, find information, search conversations, or automate any Slack task. Triggers include "check my Slack", "what channels have unreads", "send a message to", "search Slack for", "extract from Slack", "find who said", or any task requiring programmatic Slack interaction.

Installed, it changes the agent in these ways.

What this skill changes about the agent is not written down here yet. The listing was collected from its source, and the description is in its own SKILL.md.

Workflow

Runs a procedure end to end.

The skill itself

This is the whole product. A skill is instructions the model reads, so there is nothing behind the listing you cannot see first — the front matter loads with every session, and the body below it loads when the skill triggers.

7# Slack Automation
8
9Interact with Slack workspaces to check messages, extract data, and automate common tasks.
10
11## Quick Start
12
13Connect to an existing Slack browser session or open Slack:
14
15```bash
16# Connect to existing session on port 9222 (typical for already-open Slack)
17agent-browser connect 9222
18
19# Or open Slack if not already running
20agent-browser open https://app.slack.com
21```
22
23Then take a snapshot to see what's available:
24
25```bash
26agent-browser snapshot -i
27```
28
29## Core Workflow
30
311. **Connect/Navigate**: Open or connect to Slack
322. **Snapshot**: Get interactive elements with refs (@e1, @e2, etc.)
333. **Navigate**: Click tabs, expand sections, or navigate to specific channels
344. **Extract/Interact**: Read data or perform actions
355. **Screenshot**: Capture evidence of findings
36
37```bash
38# Example: Check unread channels
39agent-browser connect 9222
40agent-browser snapshot -i
41# Look for "More unreads" button
42agent-browser click @e21 # Ref for "More unreads" button
43agent-browser screenshot slack-unreads.png
44```
45
46## Common Tasks
47
48### Checking Unread Messages
49
50```bash
51# Connect to Slack
52agent-browser connect 9222
53
54# Take snapshot to locate unreads button
55agent-browser snapshot -i
56
57# Look for:
58# - "More unreads" button (usually near top of sidebar)
59# - "Unreads" toggle in Activity tab (shows unread count)
60# - Channel names with badges/bold text indicating unreads
61
62# Navigate to Activity tab to see all unreads in one view
63agent-browser click @e14 # Activity tab (ref may vary)
64agent-browser wait 1000
65agent-browser screenshot activity-unreads.png
66
67# Or check DMs tab
68agent-browser click @e13 # DMs tab
69agent-browser screenshot dms.png
70
71# Or expand "More unreads" in sidebar
72agent-browser click @e21 # More unreads button
73agent-browser wait 500
74agent-browser screenshot expanded-unreads.png
75```
76
77### Navigating to a Channel
78
79```bash
80# Search for channel in sidebar or by name
81agent-browser snapshot -i
82
83# Look for channel name in the list (e.g., "engineering", "product-design")
84# Click on the channel treeitem ref
85agent-browser click @e94 # Example: engineering channel ref
86agent-browser wait --load networkidle
87agent-browser screenshot channel.png
88```
89
90### Finding Messages/Threads
91
92```bash
93# Use Slack search
94agent-browser snapshot -i
95agent-browser click @e5 # Search button (typical ref)
96agent-browser fill @e_search "keyword"
97agent-browser press Enter
98agent-browser wait --load networkidle
99agent-browser screenshot search-results.png
100```
101
102### Extracting Channel Information
103
104```bash
105# Get list of all visible channels
106agent-browser snapshot --json > slack-snapshot.json
107
108# Parse for channel names and metadata
109# Look for treeitem elements with level=2 (sub-channels under sections)
110```
111
112### Checking Channel Details
113
114```bash
115# Open a channel
116agent-browser click @e_channel_ref
117agent-browser wait 1000
118
119# Get channel info (members, description, etc.)
120agent-browser snapshot -i
121agent-browser screenshot channel-details.png
122
123# Scroll through messages
124agent-browser scroll down 500
125agent-browser screenshot channel-messages.png
126```
127
128### Taking Notes/Capturing State
129
130When you need to document findings from Slack:
131
132```bash
133# Take annotated screenshot (shows element numbers)
134agent-browser screenshot --annotate slack-state.png
135
136# Take full-page screenshot
137agent-browser screenshot --full slack-full.png
138
139# Get current URL for reference
140agent-browser get url
141
142# Get page title
143agent-browser get title
144```
145
146## Sidebar Structure
147
148Understanding Slack's sidebar helps you navigate efficiently:
149
150```
151- Threads
152- Huddles
153- Drafts & sent
154- Directories
155- [Section Headers - External connections, Starred, Channels, etc.]
156 - [Channels listed as treeitems]
157- Direct Messages
158 - [DMs listed]
159- Apps
160 - [App shortcuts]
161- [More unreads] button (toggles unread channels list)
162```
163
164Key refs to look for:
165- @e12 - Home tab (usually)
166- @e13 - DMs tab
167- @e14 - Activity tab
168- @e5 - Search button
169- @e21 - More unreads button (varies by session)
170
171## Tabs in Slack
172
173After clicking on a channel, you'll see tabs:
174- **Messages** - Channel conversation
175- **Files** - Shared files
176- **Pins** - Pinned messages
177- **Add canvas** - Collaborative canvas
178- Other tabs depending on workspace setup
179
180Click tab refs to switch views and get different information.
181
182## Extracting Data from Slack
183
184### Get Text Content
185
186```bash
187# Get a message or element's text
188agent-browser get text @e_message_ref
189```
190
191### Parse Accessibility Tree
192
193```bash
194# Full snapshot as JSON for programmatic parsing
195agent-browser snapshot --json > output.json
196
197# Look for:
198# - Channel names (name field in treeitem)
199# - Message content (in listitem/document elements)
200# - User names (button elements with user info)
201# - Timestamps (link elements with time info)
202```
203
204### Count Unreads
205
206```bash
207# After expanding unreads section:
208agent-browser snapshot -i | grep -c "treeitem"
209# Each treeitem with a channel name in the unreads section is one unread
210```
211
212## Best Practices
213
214- **Connect to existing sessions**: Use agent-browser connect 9222 if Slack is already open. This is faster than opening a new browser.
215- **Take snapshots before clicking**: Always snapshot -i to identify refs before clicking buttons.
216- **Re-snapshot after navigation**: After navigating to a new channel or section, take a fresh snapshot to find new refs.
217- **Use JSON snapshots for parsing**: When you need to extract structured data, use snapshot --json for machine-readable output.
218- **Pace interactions**: Add sleep 1 between rapid interactions to let the UI update.
219- **Check accessibility tree**: The accessibility tree shows what screen readers (and your automation) can see. If an element isn't in the snapshot, it may be hidden or require scrolling.
220- **Scroll in sidebar**: Use agent-browser scroll down 300 --selector ".p-sidebar" to scroll within the Slack sidebar if channel list is long.
221
222## Limitations
223
224- **Cannot access Slack API**: This uses browser automation, not the Slack API. No OAuth, webhooks, or bot tokens needed.
225- **Session-specific**: Screenshots and snapshots are tied to the current browser session.
226- **Rate limiting**: Slack may rate-limit rapid interactions. Add delays between commands if needed.
227- **Workspace-specific**: You interact with your own workspace -- no cross-workspace automation.
228
229## Debugging
230
231### Check console for errors
232
233```bash
234agent-browser console
235agent-browser errors
236```
237
238### Get current page state
239
240```bash
241agent-browser get url
242agent-browser get title
243agent-browser screenshot page-state.png
244```
245
246## Example: Full Unread Check
247
248```bash
249#!/bin/bash
250
251# Connect to Slack
252agent-browser connect 9222
253
254# Take initial snapshot
255echo "=== Checking Slack unreads ==="
256agent-browser snapshot -i > snapshot.txt
257
258# Check Activity tab for unreads
259agent-browser click @e14 # Activity tab
260agent-browser wait 1000
261agent-browser screenshot activity.png
262ACTIVITY_RESULT=$(agent-browser get text @e_main_area)
263echo "Activity: $ACTIVITY_RESULT"
264
265# Check DMs
266agent-browser click @e13 # DMs tab
267agent-browser wait 1000
268agent-browser screenshot dms.png
269
270# Check unread channels in sidebar
271agent-browser click @e21 # More unreads button
272agent-browser wait 500
273agent-browser snapshot -i > unreads-expanded.txt
274agent-browser screenshot unreads.png
275
276# Summary
277echo "=== Summary ==="
278echo "See activity.png, dms.png, and unreads.png for full details"
279```

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈130
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
4,920
on trigger
The instruction body and 2 supporting files, read only when the skill fires.
2.5%
of a 200k window
Ten skills this size would take about 25% of the window before you open a file.
050k100k150k200k context window

5k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been published here. It is in the skill’s own SKILL.md, which its author has not sent to the marketplace yet.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

It writes no files and reaches no network. All it changes is how the model reasons and writes.

What it asks for
Writes filesno
Network accessno

Read from the allowed-tools line of this skill’s own SKILL.md. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

3 files, 20.2 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md8.0 kB
  • references/slack-tasks.md8.6 kB
  • templates/slack-report-template.md3.6 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 3 files you can review in full before installing. The Apache-2.0 licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

Updatesevery update its author ships, delivered through this account

You can read the whole bundle before paying — the SKILL.md above is the product, not a preview of it. What the money buys is the delivery: the folder packaged and handed to your machine by key, every update its author ships, and our support if it does not do what this listing says. The terms of use are Apache-2.0, set by the author and unchanged by buying it here.

Payment runs through Stripe, on a page like this one rather than a redirect. Once there is an account it joins the same mcprush invoice as everything else you run, so there is never a second card to enter.

Which clients pick it up on their own

A skill is a folder of text. A client with a skills folder reads it without being told; everywhere else the same text works, it is just handed to the model rather than found.

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.

Reviews

no reviews yet · no installs yet

Nobody has reviewed this skill yet. The rating is the mean of the reviews written here, so there is none until somebody writes the first.

Who can post

Only accounts that have had the skill installed for fourteen days, so a review is written after living with it rather than after reading it. Publishers may reply once.
