Initial Setup

Prerequisites (user must provide):

Bot Token: Message @BotFather → /newbot → copy token
User ID: Message @userinfobot → copy numeric ID
Deploy Key: dashboard.convex.dev → Create project → Settings → Deploy Keys → Create "Production" key

Setup steps:

# 1. Install dependencies
cd /mnt/skills/user/telegram-reminders && npm install

# 2. Save configuration
mkdir -p /mnt/user-data/outputs
cat > /mnt/user-data/outputs/telegram_config.json << 'EOF'
{
  "botToken": "YOUR_BOT_TOKEN",
  "userId": "YOUR_USER_ID",
  "deployKey": "YOUR_DEPLOY_KEY",
  "setupDate": "CURRENT_DATE"
}
EOF

# 3. Create .env.local
cat > .env.local << 'EOF'
CONVEX_DEPLOY_KEY=YOUR_DEPLOY_KEY
EOF

# 4. Set environment variables in Convex
npx convex env set TELEGRAM_BOT_TOKEN "YOUR_BOT_TOKEN"
npx convex env set TELEGRAM_USER_ID "YOUR_USER_ID"

# 5. Deploy to Convex
npx convex deploy

# 6. Test with a message
tsx scripts/send_message.ts "Setup complete!"

Critical: User must start a chat with their bot (search and press "Start") before the bot can send messages.

Core Operations

Send Immediate Message

Send text message:

tsx scripts/send_message.ts "Your message text here"

Example with special characters:

tsx scripts/send_message.ts "Hello! Here's a test message 🚀"

Timezone

All times use user's configured timezone. The Convex backend stores UTC internally; client scripts handle conversion via chrono-node.

Limitations

Files sent as documents (not inline images)
Maximum file size: 50MB (Telegram limit)
Cron granularity: 1 minute minimum
No message editing (cancel and reschedule instead)
Rate limits: 20 messages/minute per user
