Twitter/X Reader Skill

A comprehensive skill for reading and extracting data from X (formerly Twitter) tweets using multiple reliable data sources.

Overview

This skill extracts complete tweet information including text content, author details, engagement statistics, media attachments, and quoted tweets from X/Twitter URLs. It uses a multi-tier approach for maximum reliability and data completeness.

When to Use

Primary Triggers:

• User shares a tweet URL (x.com/*/status/* or twitter.com/*/status/*)
• User asks to "read this tweet" with a URL
• User requests tweet analysis, summary, or data extraction
• User mentions getting information from a specific tweet

Example User Requests:

• "What does this tweet say? https://x.com/elonmusk/status/123456789"
• "Can you read this tweet for me?"
• "Summarize this Twitter thread"
• "What are the engagement stats on this tweet?"
• "Extract the media from this tweet"

Capabilities

Data Extracted

• Tweet Content: Full text with proper formatting
• Author Information: Display name and handle (@username)
• Timestamps: Both human-readable and original format
• Engagement Stats: Likes, retweets, replies, quote tweets
• Media Attachments: Photos and videos with direct URLs
• Quote Tweets: Full quoted tweet content and author info
• Thread Context: When available

Supported URL Formats

• https://x.com/username/status/1234567890
• https://twitter.com/username/status/1234567890
• URLs with query parameters (e.g., ?s=20, ?t=abc123)
• Mobile URLs (m.twitter.com automatically handled)

Usage Examples

Basic Usage

# Read a single tweet
./scripts/read_tweet.sh "https://x.com/username/status/1234567890"

# Read a full thread (follows reply chain from the same author)
./scripts/read_thread.sh "https://x.com/username/status/1234567890"

# Fallback method using Nitter
./scripts/read_tweet_nitter.sh "https://x.com/username/status/1234567890"

Agent Instructions

When a user provides a tweet URL:

1. Validate the URL format - ensure it's a valid X/Twitter status URL
2. Use the primary script - scripts/read_tweet.sh first
3. Handle failures gracefully - if primary fails, try scripts/read_tweet_nitter.sh
4. Present data clearly - format the output for human consumption
5. Preserve context - include engagement stats and media references

Sample Response Format

The scripts return structured JSON with this format:

{
  "success": true,
  "tweet": {
    "text": "Tweet content here...",
    "author": {
      "name": "Display Name",
      "handle": "username"
    },
    "timestamp": {
      "formatted": "2024-01-15 14:30:25 UTC",
      "original": "Mon Jan 15 14:30:25 +0000 2024"
    },
    "url": "https://x.com/username/status/1234567890",
    "engagement": {
      "likes": 1250,
      "retweets": 340,
      "replies": 89,
      "quotes": 45
    },
    "media": {
      "photos": ["https://pbs.twimg.com/media/..."],
      "video": "https://video.twimg.com/..."
    },
    "quoted_tweet": {
      "text": "Quoted tweet text...",
      "author": {
        "name": "Quoted Author",
        "handle": "quoted_user"
      },
      "url": "https://x.com/quoted_user/status/987654321"
    }
  },
  "source": "fxtwitter",
  "fetched_at": 1705327825
}

Technical Implementation

Primary Method: FxTwitter API

• Endpoint: https://api.fxtwitter.com/{username}/status/{tweet_id}
• Advantages: No authentication, comprehensive data, reliable
• Rate Limits: Generous for personal use
• Response: Complete JSON with all tweet metadata

Fallback Method: Nitter Scraping (Best-Effort)

• Instances: Multiple public Nitter instances as backup
• Advantages: Works when FxTwitter is unavailable
• Limitations: Basic data extraction, no engagement stats
• Usage: Automatic fallback when primary method fails
• ⚠️ Note: Most public Nitter instances have shut down or become unreliable since 2024. This fallback is best-effort and may not return results. The FxTwitter API should be considered the only reliable method.

Error Handling

• Invalid URL format detection
• Network timeout handling
• API error response parsing
• Graceful fallback between methods
• Clear error messages for users

Dependencies

Required System Tools:

• curl - HTTP requests to APIs
• jq - JSON parsing and formatting
• bash - Script execution environment
• grep/sed - Text processing (Nitter fallback only)

Optional Enhancements:

• gdate (GNU date via Homebrew on macOS) - Better timestamp formatting

Security & Privacy

Security Features

• ✅ No external data collection - Data stays on your system
• ✅ No analytics or telemetry - No tracking or usage reporting
• ✅ Fully auditable code - Open source, readable shell scripts
• ✅ Minimal network calls - Only to FxTwitter API and Nitter instances
• ✅ No sensitive data exposure - Scripts don't store or log personal info
• ✅ Safe URL handling - Proper URL validation and sanitization

Network Connections

Approved External Hosts:

• api.fxtwitter.com - Primary data source (FxTwitter API)
• nitter.net and other Nitter instances - Fallback scraping
• No other external connections made

Data Flow:

1. User provides tweet URL
2. Script extracts username/ID from URL
3. Makes API request to FxTwitter or Nitter
4. Parses response locally
5. Returns formatted JSON (never stored permanently)

Audit Trail

All network requests include:

• Clear user-agent identification
• Minimal necessary headers only
• No authentication tokens or personal identifiers
• Requests only to extract public tweet data

Error Scenarios & Handling

Common Errors

Invalid URL Format:

{
  "error": "Invalid Twitter/X URL format",
  "expected": "x.com/user/status/123456789 or twitter.com/user/status/123456789"
}

Tweet Not Found:

{
  "error": "API Error",
  "code": 404,
  "message": "NOT_FOUND"
}

Network Failure:

{
  "error": "Failed to fetch tweet data",
  "details": "Network request failed"
}

Fallback Needed:

{
  "error": "All Nitter instances failed",
  "suggestion": "Try the main script with FxTwitter API, or wait for Nitter instances to recover"
}

Agent Error Handling

When errors occur:

1. Parse the error JSON to understand the issue
2. Try the fallback method if primary fails
3. Explain to the user what went wrong in plain language
4. Suggest alternatives (try again later, check URL format, etc.)

Advanced Features

Thread Reading

Full thread unrolling is supported via read_thread.sh:

• Given any tweet URL in a thread, walks UP the reply chain via replying_to fields
• Only collects tweets from the same author (self-reply threads)
• Returns tweets in chronological order as a JSON array
• Safety limit of 50 tweets per thread (configurable via second argument)
• Usage: ./scripts/read_thread.sh "https://x.com/user/status/123" [max_depth]

Media Handling

• Photos: Direct URLs via media.photos array (full-resolution)
• Videos: Links to MP4 files via media.videos with thumbnails and duration
• All media: Combined media.all array with type annotations for complete coverage
• Article covers: Long-form X posts ("articles") have media.article_cover extracted
• GIFs: Handled as video content
• External Links: Preserved in tweet text

Quote Tweet Recursion

The skill can extract nested quote tweets up to reasonable depth to avoid infinite loops.

Performance Notes

Response Times

• FxTwitter API: Typically 200-500ms
• Nitter Scraping: 1-3 seconds per instance
• Network Dependent: May vary based on connection quality

Caching Considerations

• No persistent caching implemented by default
• Consider temporary caching for repeated requests
• Respect rate limits of external services

Troubleshooting

Common Issues

"No tweet data in API response"

• Tweet may be deleted or protected
• Check URL format and tweet ID
• Try fallback method

"Network request failed"

• Check internet connection
• FxTwitter API may be temporarily down
• Fallback to Nitter method

"All Nitter instances failed"

• Nitter instances may be blocked or down
• Wait and retry with FxTwitter API
• Check firewall/proxy settings

Debug Mode

For debugging, run with verbose output:

bash -x scripts/read_tweet.sh "https://x.com/username/status/123"

Development & Customization

Adding New Data Sources

To add additional fallback methods:

1. Create new script in scripts/ directory
2. Follow same JSON output format
3. Update main skill logic to include new method
4. Test thoroughly and update documentation

Modifying Output Format

The JSON structure can be customized by modifying the final jq command in each script. Maintain consistency across all methods.
