The Anatomy of an Autonomous Research Agent
Moving from single-shot prompting to self-correcting agent loops with LangGraph and critic verifiers.
Beyond Single-Turn Search
Single-turn search prompts fail on complex inquiries. If you ask an LLM to *"Analyze the competitive landscape of AI veterinary diagnostics in Europe"*, it generates a plausible-sounding paragraph based on whatever 3 snippets its search API returned.
To build a true research agent, you need an **orchestrated loop of distinct sub-agents**.

The 4-Stage Agent Architecture
1. **The Planner**: Deconstructs the user goal into a DAG (Directed Acyclic Graph) of distinct inquiry tracks. 2. **The Worker Swarm**: Fetches raw data from GitHub, corporate filings, research papers, and pricing pages in parallel. 3. **The Adversarial Critic**: Scrutinizes every extracted statement. If a claim lacks primary source backing, the critic sends the worker back with a refined search vector. 4. **The Synthesizer**: Compiles the validated findings into structured markdown tables and executive summaries.

Key Metrics
In our internal benchmarks, this multi-agent loop eliminated **92% of factual hallucinations** compared to standard single-prompt search models.
