Agent SlackBot

A TypeScript CLI tool that enables AI agents and humans to interact with Slack workspaces using bot tokens (xoxb-). Unlike agent-slack which extracts user tokens from the desktop app, agent-slackbot uses standard Slack Bot tokens for server-side and CI/CD integrations.

Quick Start

bash

# Set your bot token
agent-slackbot auth set xoxb-your-bot-token

# Or set with a custom bot identifier for multi-bot setups
agent-slackbot auth set xoxb-your-bot-token --bot deploy --name "Deploy Bot"

# Verify authentication
agent-slackbot auth status

# Send a message
agent-slackbot message send C0ACZKTDDC0 "Hello from bot!"

# List channels
agent-slackbot channel list

Authentication

Bot Token Setup

agent-slackbot uses Slack Bot tokens (xoxb-) which you get from the Slack App configuration:

bash

# Set bot token (validates against Slack API before saving)
agent-slackbot auth set xoxb-your-bot-token

# Set with a custom bot identifier
agent-slackbot auth set xoxb-your-bot-token --bot deploy --name "Deploy Bot"

# Check auth status
agent-slackbot auth status

# Clear stored credentials
agent-slackbot auth clear

Multi-Bot Management

Store multiple bot tokens and switch between them:

bash

# Add multiple bots
agent-slackbot auth set xoxb-deploy-token --bot deploy --name "Deploy Bot"
agent-slackbot auth set xoxb-alert-token --bot alert --name "Alert Bot"

# List all stored bots
agent-slackbot auth list

# Switch active bot
agent-slackbot auth use deploy

# Use a specific bot for one command (without switching)
agent-slackbot message send C0ACZKTDDC0 "Alert!" --bot alert

# Remove a stored bot
agent-slackbot auth remove deploy

# Disambiguate bots with same ID across workspaces
agent-slackbot auth use T123456/deploy

The

--bot <id>

flag is available on all commands to override the active bot for a single invocation.

Getting a Bot Token

Go to api.slack.com/apps
Create New App (or select existing)
Go to OAuth & Permissions
Add required bot token scopes (see below)
Install app to workspace
Copy the Bot User OAuth Token (starts with
```
xoxb-
```
)

Required Bot Token Scopes

Scope	Used For
`chat:write`	Sending messages
`channels:history`	Reading public channel messages
`channels:read`	Listing public channels
`channels:join`	Joining public channels
`groups:history`	Reading private channel messages
`groups:read`	Listing private channels
`users:read`	Listing users
`users:read.email`	Reading user email addresses
`reactions:write`	Adding/removing reactions
`reactions:read`	Listing reactions

Environment Variables (CI/CD)

For CI/CD pipelines, set these environment variables instead of using

auth set

bash

export E2E_SLACKBOT_TOKEN=xoxb-your-bot-token
export E2E_SLACKBOT_WORKSPACE_ID=T123456
export E2E_SLACKBOT_WORKSPACE_NAME="My Workspace"

Commands

Message Commands

bash

# Send a message
agent-slackbot message send <channel> <text>
agent-slackbot message send C0ACZKTDDC0 "Hello world"

# Send a threaded reply
agent-slackbot message send C0ACZKTDDC0 "Reply" --thread <ts>

# List messages
agent-slackbot message list <channel>
agent-slackbot message list C0ACZKTDDC0 --limit 50

# Get a single message by timestamp
agent-slackbot message get <channel> <ts>

# Get thread replies (includes parent message)
agent-slackbot message replies <channel> <thread_ts>
agent-slackbot message replies C0ACZKTDDC0 1234567890.123456 --limit 50

# Update a message (bot's own messages only)
agent-slackbot message update <channel> <ts> <new-text>

# Delete a message (bot's own messages only)
agent-slackbot message delete <channel> <ts> --force

Channel Commands

bash

# List channels the bot can see
agent-slackbot channel list
agent-slackbot channel list --limit 50

# Get channel info
agent-slackbot channel info <channel>
agent-slackbot channel info C0ACZKTDDC0

User Commands

bash

# List users
agent-slackbot user list
agent-slackbot user list --limit 50

# Get user info
agent-slackbot user info <user-id>

Reaction Commands

# Add reaction
agent-slackbot reaction add <channel> <ts> <emoji>
agent-slackbot reaction add C0ACZKTDDC0 1234567890.123456 thumbsup

# Remove reaction
agent-slackbot reaction remove <channel> <ts> <emoji>

Output Format

JSON (Default)

All commands output JSON by default for AI consumption:

json

{
  "ts": "1234567890.123456",
  "channel": "C0ACZKTDDC0",
  "text": "Hello world"
}

Pretty (Human-Readable)

Use

--pretty

flag for formatted output:

bash

agent-slackbot channel list --pretty

Common Patterns

See

references/common-patterns.md

for typical AI agent workflows.

Templates

See

templates/

directory for runnable examples:

```
post-message.sh
```
- Send messages with error handling
```
monitor-channel.sh
```
- Monitor channel for new messages
```
workspace-summary.sh
```
- Generate workspace summary

Error Handling

All commands return consistent error format:

json

{
  "error": "No credentials. Run \"auth set\" first."
}

Common errors:

```
missing_token
```
: No credentials configured
```
invalid_token_type
```
: Token is not a bot token (must start with xoxb-)
```
not_in_channel
```
: Bot needs to join the channel first
```
slack_webapi_rate_limited_error
```
: Hit rate limit (auto-retries with backoff)

Configuration

Credentials stored in:

~/.config/agent-messenger/slackbot-credentials.json

Format:

json

{
  "current": {
    "workspace_id": "T123456",
    "bot_id": "deploy"
  },
  "workspaces": {
    "T123456": {
      "workspace_id": "T123456",
      "workspace_name": "My Workspace",
      "bots": {
        "deploy": {
          "bot_id": "deploy",
          "bot_name": "Deploy Bot",
          "token": "xoxb-..."
        },
        "alert": {
          "bot_id": "alert",
          "bot_name": "Alert Bot",
          "token": "xoxb-..."
        }
      }
    }
  }
}

Security: File permissions set to 0600 (owner read/write only)

Key Differences from agent-slack

Feature	agent-slack	agent-slackbot
Token type	User token (xoxc-)	Bot token (xoxb-)
Token source	Auto-extracted from desktop app	Manual from Slack App config
Message search	Yes	No (requires user token)
File operations	Yes	No
Snapshot	Yes	No
Edit/delete messages	Any message	Bot's own messages only
Workspace management	Multi-workspace	Multi-bot, multi-workspace
CI/CD friendly	Requires desktop app	Yes (just set token)

Limitations

No real-time events / Socket Mode
No message search (requires user token scope)
No file upload/download
No workspace snapshot
Bot can only edit/delete its own messages
Bot must be invited to private channels
No scheduled messages
Plain text messages only (no blocks/formatting)

Troubleshooting

agent-slackbot: command not found

The

agent-messenger

package is not installed. Run it directly using a package runner. Ask the user which one to use:

bash

npx -p agent-messenger agent-slackbot ...
bunx -p agent-messenger agent-slackbot ...
pnpm dlx --package agent-messenger agent-slackbot ...

If you already know the user's preferred package runner, use it directly instead of asking.
