Scan

Trend Scanning

Scan current trends across Hacker News and GitHub for any topic.

When to Use

• "What's happening in [domain]?"
• Research before starting a new project
• Staying current with technology trends
• Finding emerging tools and patterns

Basic Scan

scan_trends(topic: "WebAssembly")

Returns:

• Signals from HN and GitHub
• Detected patterns across sources
• Relevance scoring based on your profile
• Actionable suggestions

Targeted Scans

HN only (community discussions):

scan_trends(topic: "AI agents", sources: ["hackernews"])

GitHub only (code and repos):

scan_trends(topic: "rust CLI tools", sources: ["github"])

Deep Dive

After finding interesting signals:

explore_pattern(topic: "specific-pattern")

Perplexity Integration

For aggregated web search across Reddit, Twitter, arXiv, and more:

perplexity_search("your topic in the context of your domains")

Pattern-radar generates ready-to-use Perplexity queries in scan results.

Understanding Results

Signals: Individual items (HN stories, GitHub repos)

• Score: Engagement level (HN points, GitHub stars)
• Source: Where it came from

Patterns: Clusters of related signals

• Relevance: How well it matches your domains
• Actions: Suggested next steps

Tips

1. Scan broad topics first, then narrow down
2. Use your profile domains for automatic relevance scoring
3. Combine with perplexity_search for comprehensive coverage
4. Save interesting patterns to shared-memory
