Permissions	Y/n prompts	Approve/Deny buttons
Parallel work	Multiple terminals	Threads = isolated sessions
File sharing	cat or copy-paste	Drag & drop with preview
Notifications	Watch the terminal	Alerts when tasks complete
Streaming	Live terminal output	Watch responses as they generate
Smart context	Manual file inclusion	Frequently-used files auto-included

3. Configure

Use the built-in config CLI to securely store your Slack credentials:

ccslack-config set SLACK_BOT_TOKEN=xoxb-...
ccslack-config set SLACK_APP_TOKEN=xapp-...
ccslack-config set SLACK_SIGNING_SECRET=...

Config CLI Commands:

Command	Description
ccslack-config set KEY=VALUE	Store a configuration value
ccslack-config get KEY	Retrieve a configuration value
ccslack-config list	List all stored configuration
ccslack-config delete KEY	Remove a configuration value
ccslack-config path	Show config file locations

Configuration is encrypted and stored in ~/.slack-claude-code/config.enc. Sensitive values (tokens, secrets) are masked when displayed.

Alternative: You can also use environment variables or a .env file. Config values take precedence over environment variables.

Where to find these values:

• SLACK_BOT_TOKEN: Your App → OAuth & Permissions → Bot User OAuth Token
• SLACK_APP_TOKEN: Your App → Basic Information → App-Level Tokens → (token you created with connections:write)
• SLACK_SIGNING_SECRET: Your App → Basic Information → App Credentials → Signing Secret

4. Start the Slack bot

You can now run ccslack in your terminal. The working directory where you start the executable will be the default working directory for your Claude Code session(s). If you have a .env file in this directory, it will automatically be loaded.

Usage

Type messages in any channel where the bot is installed. The main channel is a single Claude Code session. If you click reply to any message and start a thread, this will be a new Claude Code session.
