Aggregating Crypto News

Overview

Aggregate cryptocurrency news from 50+ authoritative sources via RSS feeds with real-time scanning, coin/category filtering, and relevance scoring.

Prerequisites

1. Python 3.8+ installed
2. Dependencies: pip install feedparser requests
3. Internet connectivity for RSS feed access

Instructions

1. Assess user intent - determine filters needed:

   • General news: no filters, use defaults
   • Coin-specific: extract symbol (BTC, ETH, etc.)
   • Category-specific: extract category (defi, nft, regulatory, etc.)
   • Time-specific: extract window (1h, 4h, 24h, 7d)

2. Run the aggregator with appropriate filters:

   # Default scan (top 20, past 24h, relevance sorted)
   python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py
   
   # Coin-specific scan
   python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --coin BTC --period 4h
   
   # Category filter
   python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --category defi --top 30
   
   # Multiple filters
   python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --coin ETH --category defi --period 24h --top 15
   

3. Export results for downstream processing:

   python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --format json --output news.json
   

4. Present results to the user:

   • Show source, title, age, and relevance score
   • Highlight market-moving keywords if present
   • Provide links for full articles
   • Summarize meta information (sources checked, articles found)

Output

Table showing articles ranked by relevance score (0-100) based on market-moving keyword detection, source authority, and recency:
