This is a minimal example of a Go Slackbot that uses the Coder chat API's dynamic tools feature to let an LLM interact with Slack. It is intended as a starting point — fork it, customize the system prompt, and add your own tools.

1. Bot is @mentioned in Slack
2. Creates a new Coder chat with dynamic tools (slack_send_message, slack_react_to_message, etc.)
3. When the LLM calls a dynamic tool → executes it against the Slack API → submits results back
4. Chat resumes until complete

Follow-up mentions in the same thread reuse the same Coder chat.

export SLACK_BOT_TOKEN="xoxb-..."        # Bot User OAuth Token
export SLACK_APP_TOKEN="xapp-..."        # App-Level Token (socket mode)
export CODER_URL="https://your-coder.example.com"
export CODER_SESSION_TOKEN="..."         # coder tokens create

go build -o slackbot .
./slackbot

1. Create a Slack app at https://api.slack.com/apps (or use the manifest in slack-app-manifest.yaml)
2. Enable Socket Mode (generates the xapp- token)
3. Subscribe to bot events: app_mention
4. Add bot scopes: app_mentions:read, chat:write, reactions:write, channels:history, groups:history, users:read, users:read.email, assistant:write
5. Install to workspace
