Building Biological Tool-Use Agents: Architecture and Patterns The vision of agentic omics — autonomous AI systems that orchestrate biological discovery — depends on a deceptively simple capability: tool use. An agent that can reason about biology but cannot access BLAST, AlphaFold, or single-cell analysis pipelines is like a biologist who understands theory but has never touched a pipette. This post provides a practical architecture for building biological tool-use agents. We cover the essential tool inventory, the unique error-handling challenges of biological data, prompt engineering patterns for biological reasoning, and a reference architecture based on the ReAct (Reason + Act) loop. This is the “how-to” companion to Post 13’s conceptual overview and Post 14’s vision of agentic omics. ...

When a new foundation model in computational biology is released, the accompanying paper inevitably features tables of bolded numbers demonstrating state-of-the-art performance. Whether it is predicting protein structures or annotating single-cell data, the claims are often spectacular. But how do we truly know if these AI systems work in ways that matter to biology, rather than just optimizing arbitrary computational metrics? For the vision of Agentic Omics to become reality—where autonomous agents orchestrate models like AlphaFold and DNABERT-2 to drive drug discovery—we need a rigorous understanding of when these models succeed, when they hallucinate, and when their benchmarks deceive us. Claims of AI breakthroughs are only as strong as their evaluation methodologies. ...

The bottleneck for AI in computational biology is rarely a shortage of sophisticated models; it is the sheer difficulty of making biological data AI-ready. The “Agentic Omics” vision—where autonomous AI agents orchestrate domain-specific models to accelerate drug discovery—fundamentally rests on the assumption that these agents have access to standardized, clean, and computable data. In this post, we explore the unglamorous but critical foundation of omics AI: the data infrastructure. We trace the journey from raw sequencing reads to the structured tensor formats required by modern foundation models, exploring the evolving standards, the scale of the challenge, and how cloud infrastructure is adapting. ...

Welcome back to Agentic Omics: When AI Reads the Book of Life. In our first post, we mapped the complex, multi-layered territory of modern biological data. We saw that while fields like metabolomics are still wrangling with extreme chemical complexity, disciplines defined by sequences—genomics, transcriptomics, and proteomics—are experiencing a massive influx of AI-ready data. But data alone isn’t enough. The true catalyst of the current biological AI revolution is a specific architectural breakthrough originally designed to translate English to French: the Transformer. ...
