Platform-Specific Formatting

X (Twitter) Best Practices

• Character limit: 280 characters
• Hashtags: 2-3 relevant hashtags at the end
• Mentions: @username for mentions
• Links: Automatically shortened
• Media: Up to 4 images, 1 GIF, or 1 video

# Post with xurl
xurl post "Check out our new update! 🚀 #AI #Tech"

# Post with image
xurl post "New feature demo" --media ./screenshot.png

# Reply to tweet
xurl reply  "Thanks for the mention!"

Telegram Best Practices

• Markdown/HTML support for rich formatting
• No character limit (for all practical purposes)
• Supports: images, documents, polls, keyboards
• Channels: Use @channelusername or numeric chat ID

# Send text message
curl -s -X POST "https://api.telegram.org/bot$TOKEN/sendMessage" \
  -d chat_id="$CHAT_ID" \
  -d text="*Bold* _Italic_ [Link](https://example.com)" \
  -d parse_mode="MarkdownV2"

# Send photo
curl -s -X POST "https://api.telegram.org/bot$TOKEN/sendPhoto" \
  -F chat_id="$CHAT_ID" \
  -F photo="@./image.jpg" \
  -F caption="Photo caption"

Discord Best Practices

• Embeds for rich messages
• Webhook username/avatar customization
• Max 2000 characters per message
• Supports: attachments, embeds, reactions

# Simple message via webhook
curl -s -X POST "$DISCORD_WEBHOOK_URL" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Hello from webhook!",
    "username": "MyBot",
    "avatar_url": "https://example.com/avatar.png"
  }'

# Rich embed message
curl -s -X POST "$DISCORD_WEBHOOK_URL" \
  -H "Content-Type: application/json" \
  -d '{
    "embeds": [{
      "title": "Announcement",
      "description": "New release is out!",
      "color": 5814783,
      "fields": [
        {"name": "Version", "value": "2.0", "inline": true},
        {"name": "Date", "value": "2026-01-15", "inline": true}
      ]
    }]
  }'

Multi-Platform Posting Workflow

1. Prepare Content

# Base content
TITLE="Big Announcement"
BODY="We just launched something amazing. Check it out!"
LINK="https://example.com/news"
IMAGE="./announcement.png"

2. Platform-Specific Versions

# X (Twitter) - Concise
TWEET="$TITLE: $BODY $LINK #News #Launch"

# Telegram - Detailed with markdown
TG_MSG="*$TITLE*\n\n$BODY\n\n[Read more]($LINK)"

# Discord - Rich embed format
DISCORD_JSON=$(cat <<EOF
{
  "content": "",
  "embeds": [{
    "title": "$TITLE",
    "description": "$BODY",
    "url": "$LINK",
    "color": 3447003
  }]
}
EOF
)

3. Post in Parallel

# Post to all three platforms (background for speed)
xurl post "$TWEET" --media "$IMAGE" &
curl -s -X POST "https://api.telegram.org/bot$TOKEN/sendPhoto" \
  -F chat_id="$CHAT_ID" -F photo="@$IMAGE" -F caption="$TG_MSG" &
curl -s -X POST "$DISCORD_WEBHOOK" \
  -H "Content-Type: application/json" -d "$DISCORD_JSON" &
wait
echo "Posted to all platforms!"

Tips for Effective Cross-Posting

1. Tailor per platform: Don't just copy-paste identically
2. Timing matters: Post when each platform's audience is active
3. Use platform features: Threads on X, pins on Telegram, embeds on Discord
4. Track engagement: Use platform analytics to see what works
5. Handle errors gracefully: If one platform fails, others should still post
