PRD: Aggregating Crypto News

PRD: Aggregating Crypto News

Document Control

Executive Summary

The aggregating-crypto-news skill provides real-time cryptocurrency news aggregation from multiple authoritative sources including RSS feeds, news APIs, and social media. It enables traders and analysts to stay informed about market-moving events, protocol updates, regulatory changes, and ecosystem developments without manually monitoring dozens of sources.

Value Proposition: Consolidate crypto news from 50+ sources into a single, filterable feed with relevance scoring and coin-specific filtering.

Problem Statement

Current Pain Points

1. Information Overload: Crypto news is scattered across hundreds of sources - Twitter, Discord, Telegram, news sites, protocol blogs, exchange announcements
2. Signal vs Noise: Separating market-moving news from promotional content and spam is time-consuming
3. Missed Events: Important announcements (airdrops, forks, delistings) can be missed without constant monitoring
4. No Central Feed: No single tool aggregates RSS feeds, Twitter spaces, Discord announcements, and official blogs

Impact of Not Solving

• Traders miss alpha from early news detection
• Portfolio managers react late to regulatory changes
• Researchers waste hours manually checking sources
• Teams lack shared news intelligence

Functional Requirements

REQ-1: Multi-Source Aggregation

• Fetch from RSS feeds (CoinDesk, CoinTelegraph, Decrypt, The Block, etc.)
• Parse feed entries with proper date handling
• Deduplicate across sources based on title similarity

REQ-2: Relevance Scoring

• Score articles based on keyword matches
• Boost scores for market-moving terms (exploit, hack, listing, partnership)
• Penalize promotional/sponsored content

REQ-3: Filtering System

• Time-based filtering (1h, 4h, 24h, 7d)
• Coin/token filtering with symbol matching
• Category filtering with multi-select
• Source filtering

REQ-4: Output Formatting

• Table format for terminal display
• JSON format for programmatic use
• CSV format for spreadsheet analysis
• Minimal format for quick scanning

REQ-5: Caching

• Cache feed responses to reduce API calls
• Configurable TTL (default 5 minutes)
• Cache invalidation on demand

Non-Goals

• Social Media Scraping: No Twitter/Discord/Telegram scraping (API access required, separate skill)
• Sentiment Analysis: Basic keyword detection only (sentiment-analyzer is separate skill)
• Alerts/Notifications: No push notifications (separate alerting system)
• Historical Archive: No long-term storage (scan only, not archive)
• Translation: No multi-language support (English sources only)
