Scientific Agent Skills is an open-source toolkit of 134 ready-to-use scientific domain skills for AI agents, covering cancer genomics, drug-target binding prediction, molecular dynamics, RNA velocity analysis, geospatial science, and time series forecasting. Each skill integrates with 78+ scientific databases and is backed by 70+ optimized Python packages, installable with a single npx command into agents like Claude Code, Cursor, or Codex. The core idea is separating scientific compute from the agent's reasoning loop. Instead of asking an LLM to hallucinate bioinformatics pipelines, you give it callable skills that actually connect to NCBI, PDB, ChEMBL, and other authoritative data sources. Optional cloud compute via Modal handles GPU-intensive workloads — molecular dynamics simulations, protein structure inference — without requiring local hardware. Forty-plus model integrations mean the skills layer is agent-agnostic. With 18.1k GitHub stars, this project is filling an obvious gap: the agent ecosystem has exploded in developer tools but scientific workflows have lagged behind. A bioinformatician can now wire up a Claude Code agent that genuinely queries gene expression databases, runs differential analysis, and interprets results — without writing custom integration code for each data source.

ORAC-NT
MedChem copilot that blocks toxic molecular modifications before you make them

ORAC-NT is an open-source medicinal chemistry copilot for early-stage drug discovery. Unlike general-purpose AI tools, it actively blocks synthetically infeasible or toxic molecular modifications — it won't just suggest them — and explains exactly why each transformation is rejected before proposing valid alternatives. The tool provides guided transformation pathways for common medicinal chemistry operations: halogenation, methylation, scaffold simplification, bioisosteric replacement, and solubility optimization. Each step generates an audit trail formatted for regulatory documentation, addressing a real gap in AI-assisted drug design where there's no clear chain of reasoning for a discovery team's choices. The target user is a medicinal chemist doing early lead optimization who wants AI assistance but can't afford hallucinated suggestions. ORAC-NT's guardrail-first design philosophy means it says 'no' often, with explanation — the opposite of most AI tools that optimize for appearing helpful.
Reviewer scorecard
“The npx install pattern means I can wire 78 scientific databases into my agent in minutes. The Modal integration for GPU workloads is a thoughtful design decision — it keeps the local agent lightweight while offloading the heavy compute. This is exactly the kind of batteries-included toolkit the scientific computing community needs.”
“The regulatory audit trail feature alone makes this worth evaluating for any pharma team using AI. The FDA is going to want documentation on AI-assisted design decisions, and ORAC-NT is the only open-source tool I've seen that generates that output by design rather than as an afterthought.”
“Database integrations go stale fast — API endpoints change, authentication requirements shift, data formats get versioned. A 134-skill library is a massive maintenance burden for what appears to be a small team. Check the issue tracker before depending on this for anything publication-critical.”
“Drug discovery is a domain where a wrong answer has real stakes, and 'open source with a paid cloud tier' is not how serious pharma teams procure safety-critical software. Until this has been validated against known drug series and peer-reviewed, treating it as anything other than a research prototype would be reckless.”
“This is accelerating AI-assisted drug discovery and genomics research by months. When an AI agent can natively call ChEMBL binding affinity data and run molecular docking simulations as skills, we've collapsed the distance between research hypothesis and computational validation. The implications for rare disease research are enormous.”
“AI in drug discovery has mostly been a hype layer on top of existing cheminformatics. ORAC-NT's approach — domain-specific guardrails, explainability, audit trails — is what responsible AI deployment actually looks like in high-stakes science. This design pattern will propagate to other regulated domains.”
“For science communicators and data journalists, this is a game-changer. Instead of waiting for a bioinformatician to run an analysis, you can point an agent at the skill library and get interactive cancer genomics visualizations yourself. The barrier to data-driven science storytelling just dropped significantly.”
“The UX philosophy here is fascinating from a design perspective: an AI tool that's deliberately more restrictive than helpful. That's a radical choice that goes against every growth metric. But in professional scientific contexts, trust comes from knowing the tool will say no to bad ideas. That's a design principle worth stealing.”
