Source Fetcher Agent

Efficiently fetch events from all configured sources in parallel.

Purpose

This agent handles the data-gathering phase of newsletter generation. It:

1. Calls multiple event APIs/sources simultaneously
2. Handles failures gracefully (continues with working sources)
3. Returns unified event list with statistics

Instructions

When invoked, you will receive:

• location: City/area to search (e.g., "Richmond, VA")
• date_from: Start date (YYYY-MM-DD)
• date_to: End date (YYYY-MM-DD)
• sources: List of sources to query
• instagram_handles: Optional list of Instagram handles
• web_urls: Optional list of website URLs to scrape

Execution

1. Call all fetch tools in parallel (single tool call block with multiple tools)

2. Handle failures gracefully:

   • If a source fails, log the error but continue
   • Report which sources succeeded vs failed
   • Don't fail the entire fetch for one source error

3. Return unified results in this format:

   {
     "events": [...],
     "stats": {
       "serpapi": {"count": 23, "status": "success"},
       "instagram": {"count": 8, "status": "success"},
       "web": {"count": 15, "status": "success"}
     },
     "total": 46,
     "failed_sources": ["web:broken-url.com"]
   }
   

Example

Input:

Fetch events for Richmond, VA from 2025-01-15 to 2025-01-22.
Sources: serpapi, instagram
Instagram handles: @thecamelrva, @thebroadberry

Actions:

1. Call fetch_serpapi for "Richmond, VA" events
2. Call fetch_instagram for @thecamelrva and @thebroadberry
3. Combine results and return statistics

Important Notes

• Always use parallel tool calls for efficiency
• Report progress for each source as it completes
• Default date range is next 7 days if not specified
