A simple Slack app that monitors your messages and sends you a private reminder when you end messages with a period, encouraging you to be more friendly in your communication.

• Monitors only messages from the app owner (you)
• Detects messages ending with periods
• Sends private DM reminders with friendly suggestions
• Ignores bot messages, edits, and very short messages

1. Go to Slack API and click "Create New App"
2. Choose "From scratch"
3. Give it a name like "Friendly Reminder Bot"
4. Select your workspace

In your Slack app settings:

1. Go to "OAuth & Permissions"
2. Add these Bot Token Scopes:
   • chat:write - To send messages
   • channels:history - To read channel messages
   • groups:history - To read private channel messages
   • im:history - To read direct messages
   • mpim:history - To read group direct messages

1. In "OAuth & Permissions", click "Install to Workspace"
2. Authorize the app
3. Copy the "Bot User OAuth Token" (starts with xoxb-)

In Val Town, set these environment variables:

• SLACK_BOT_TOKEN: Your bot token from step 3
• SLACK_OWNER_USER_ID: Your Slack user ID (see instructions below)

1. In Slack, click on your profile picture
2. Click "Profile"

1. In your Slack app settings, go to "Event Subscriptions"
2. Enable events
3. Set the Request URL to your Val Town webhook URL: https://[your-username]-slackwebhook.web.val.run
4. Under "Subscribe to bot events", add:
   • message.channels - Messages in public channels
   • message.groups - Messages in private channels
   • message.im - Direct messages

After adding event subscriptions, you'll need to reinstall the app to your workspace with the new permissions.

1. Slack sends webhook events to the Val Town endpoint
2. The webhook filters for messages from you (the owner)
3. If a message ends with a period, it sends you a private DM reminder
4. The reminder suggests using friendlier punctuation like ! or 😊

Send a message in any channel that ends with a period, like:

This is a test message.

You should receive a private DM from the bot with a friendly reminder!
