1.1 Workflow description

Title
Multi-tool research agent for animal advocacy with OpenRouter, Serper & Open Paws DB
Workflow name
Multi-tool research agent for animal advocacy with OpenRouter, Serper & Open Paws DB

This general-purpose sub-agent combines multiple research and automation tools to support high-impact decision-making for animal advocacy workflows. It’s designed to act as a reusable, modular unit within larger multi-agent systems—handling search, scraping, scoring, and domain-specific semantic lookup.

It powers many of the advanced workflows released by Open Paws and serves as a versatile backend utility agent.


🛠️ What It Does

  • Performs real-time Google Search using Serper
  • Scrapes and extracts page content using Jina AI and Scraping Dog
  • Conducts semantic search over the Open Paws knowledge base
  • Generates OpenAI embeddings for similarity search and analysis
  • Routes search and content analysis through OpenRouter LLMs
  • Connects with downstream tools like the Text Scoring Sub-Workflow to evaluate message performance

> 🧩 This agent is typically used as a sub-workflow in larger automations where agents need access to external tools or advocacy-specific knowledge.


🧠 Domain Focus: Animal Advocacy

The agent is pre-configured to interface with the Open Paws database—an open-source, animal advocacy-specific knowledge graph—and is optimized for content and research tasks relevant to farmed animal issues, corporate campaigns, and activist communication.


🔗 Integrated Tools and APIs

Tool Purpose
Serper API Real-time Google Search queries
Jina AI Web scraping and content extraction
Scraping Dog Social media scraping where Jina is blocked
OpenAI API Embedding generation for semantic search
OpenRouter Proxy to multiple LLMs (e.g., GPT-4, Claude)
Open Paws DB Advocacy-specific semantic knowledge base

📦 Use Cases

  • Create and evaluate online content (e.g. social media, emails, petitions) for predicted performance and advocacy alignment
  • Act as a research and reasoning agent within multi-agent workflows
  • Automate web and social media research for real-time campaign support
  • Surface relevant facts or arguments from an advocacy-specific knowledge base
  • Assist communications teams with message testing and content ideation
  • Monitor search results and scrape pages to inform rapid response messaging
