📄 Paper: Scientific Agent Skills is described in Scientific Agent Skills: A Library of Procedural Knowledge for Research Agents (arXiv:2609.00065). If you use these skills in your research, please cite the paper.

A collection of 177 scientific and research skills for AI agents, created by K-Dense. The skills cover biology, chemistry, medicine, physics, engineering, Earth science, data analysis, and scientific communication. Each provides guidance for a specific package, data source, or workflow, including the scientific conventions and validation checks needed to use it.

The collection follows the open Agent Skills standard and works with Cursor, Claude Code, Codex, Google Antigravity, and other compatible hosts. It is also a portable Agent Plugins package (plugin.json + skills/), so clients that support that standard can load the collection as one plugin. Browse the illustrated skill guides, skill categories, or complete catalog to choose the skills relevant to your work.

⭐ Help make AI for science easier to discover: If Scientific Agent Skills saves you time, teaches your agent a workflow, or helps your lab move faster, please star this repository. A star is a public signal that these open, reusable research skills are worth maintaining: it helps scientists, engineers, and open-source contributors find the project, shows which agent-skill standards are gaining real adoption, and gives us a clear reason to keep expanding the collection for the community.

These skills enable your AI agent to seamlessly work with specialized scientific libraries, databases, and tools across multiple scientific domains. While the agent can use any Python package or API on its own, these explicitly defined skills provide curated documentation and examples that make it significantly stronger and more reliable for the workflows below:

Recorded walkthroughs of these skills on real research tasks, from the K-Dense YouTube channel:

This repository provides 177 scientific and research skills organized into the following categories:

• 100+ Scientific & Financial Databases - The Database Lookup skill documents 80 databases with public, registered, or licensed access (PubChem, ChEMBL, UniProt, COSMIC, ClinicalTrials.gov, FRED, USPTO, and more), including endpoint selection, pagination, and provenance. Dedicated skills cover DepMap, Imaging Data Commons, PrimeKG, NCATS ARAX, U.S. Treasury Fiscal Data, Hugging Science, OneKGPd, Genomic Intelligence, and AlphaGenome. Multi-database packages such as BioServices, Biopython, and gget add further coverage
• 70+ Optimized Python Package Skills - Explicitly defined, version-aware workflows for RDKit, Scanpy, PyTorch Lightning, scikit-learn, PyTDC, PathML, pydicom, NeuroKit2, PufferLib, QuTiP, GeoPandas, pymatgen, BioPython, Qiskit, Molecular Dynamics (OpenMM/MDAnalysis), and others. The agent can still use any Python package; these skills provide stronger, safer guidance for the packages listed
• 9 Scientific Integration Skills - Explicitly defined skills for Benchling, DNAnexus, LatchBio, OMERO, Protocols.io, Open Notebook, Ginkgo Cloud Lab, LabArchives, and Opentrons. Again, the agent is not limited to these — any API or platform reachable from Python is fair game; these skills are the optimized, pre-documented paths
• 30+ Analysis & Communication Tools - Literature review, evidence-traceable scientific writing, confidential peer review, document processing, Paperclip (full-text papers, FDA/PMDA/EMA filings, and trial registries with line-pinned citations), Paperzilla, Exa Search, macro-free PPTX posters, slides, schematics, infographics, Mermaid diagrams, and more
• 10+ Research & Clinical Tools - Evidence-bounded hypothesis generation, grant writing, aggregate clinical decision-support research, clinician-authored treatment-plan formatting, PK/PD modelling and simulation (NCA, population PK, exposure-response, bioequivalence, first-in-human dose), BIDS, ISO standards-readiness evidence preparation (ISO 13485, ISO 14971, ISO/IEC 17025, ISO 15189), analytical method validation and transfer (ICH Q2(R2)/Q14, ICH M10, USP, CLSI EP), scenario analysis, and workflow-derived skill drafting with Autoskill

Every skill has a SKILL.md with its purpose, workflow, and version metadata. Depending on the workflow, it also includes code examples, reference documentation, executable helpers, or templates. Skills with bundled scripts/ have a corresponding test suite under tests/<skill-name>/ and a dependency entry in tests/skill-requirements.toml.

The docx, pdf, pptx, and xlsx document skills, which were vendored from anthropics/skills under Anthropic's own license, are no longer bundled. The collection now has 177 skills; install those four from Anthropic's repository if you rely on them. Scientific Slides now builds PowerPoint decks with PptxGenJS or python-pptx and reviews them through LibreOffice and its own rendering and validation scripts.

This update refreshes all 181 skills, including package and API guidance, dependency requirements, reference documentation, and validation workflows. Highlights include:

• Database retrieval: Database Lookup now catalogs 80 sources, with access requirements, retrieval contracts, and provenance checks.
• Package compatibility: Updated documented baselines include PathML 3.0.8, GeoPandas 1.2.0, and build123d 0.13.0 for lab hardware CAD. PufferLib distinguishes native 5.0, PyPI 3.0.0, and historical 4.0 workflows.
• Image generation and agent tooling: Generate Image uses the OpenRouter Image API with model discovery and request validation. Pi Agent documents Pi 0.99.2, native MCP, and updated ecosystem packages.
• RNA-seq workflow boundaries: Bulk RNA-seq prepares reads and validated counts for a PyDESeq2 handoff; Pathway Enrichment covers downstream enrichment.

Each skill records its own compatibility requirements and validation scope. Check those details before reusing an older workflow; local tests, live-service checks, and illustrative examples have different coverage.

Install Scientific Agent Skills with a single command:

npx skills add K-Dense-AI/scientific-agent-skills

This is a common standards-based installer for supported Agent Skills hosts, including current versions of Claude Code, Claude Cowork, Codex, Gemini CLI, Google Antigravity, and Cursor. Confirm installation paths and optional metadata behavior in your host's current documentation.

If you use the GitHub CLI (v2.90.0+), you can install skills with gh skill:

# Browse and install interactively
gh skill install K-Dense-AI/scientific-agent-skills

# Install a specific skill directly
gh skill install K-Dense-AI/scientific-agent-skills scanpy

# Target a specific agent host
gh skill install K-Dense-AI/scientific-agent-skills --agent cursor
gh skill install K-Dense-AI/scientific-agent-skills --agent claude-code
gh skill install K-Dense-AI/scientific-agent-skills --agent codex
gh skill install K-Dense-AI/scientific-agent-skills --agent gemini

gh skill automatically installs to the correct directory for your agent host and records provenance metadata for supply chain integrity.

Pin to a specific release tag or commit SHA for reproducible installs:

# Pin to a release tag
gh skill install K-Dense-AI/scientific-agent-skills --pin v2.71.0

# Pin to a commit SHA
gh skill install K-Dense-AI/scientific-agent-skills --pin abc123def

# Check for updates interactively
gh skill update

# Update all installed skills
gh skill update --all

This repository is a valid Agent Plugins 1.0.0 package: root plugin.json plus Agent Skills under skills/. Clients that support the standard discover every immediate child of skills/ that contains a SKILL.md.

Cursor — symlink or copy the repo into the local plugins directory, then reload:

mkdir -p ~/.cursor/plugins/local
ln -s "$(pwd)" ~/.cursor/plugins/local/scientific-agent-skills

Restart Cursor or run Developer: Reload Window, then confirm the plugin and its skills appear under Customize. See Cursor plugins.

Codex — install from a local checkout (confirm the current CLI flag names in Codex docs):

codex plugins install .

Compatible clients (Cursor, Codex, GitHub Copilot, VS Code, Kiro, and others listed at agent-plugins.org) share the same package layout; installation UX stays client-specific.

Agent hosts differ in install paths, discovery settings, and support for optional frontmatter fields. npx skills add (Option 1) commonly installs into the ~/.agents/skills/ convention, with project-scoped installs under .agents/skills/; confirm both paths against your host's current documentation. To install manually on a host configured to scan one of those locations:

git clone https://github.com/K-Dense-AI/scientific-agent-skills.git ~/.agents/skills/scientific-agent-skills   # user-level
git clone https://github.com/K-Dense-AI/scientific-agent-skills.git .agents/skills/scientific-agent-skills      # project-level

For Hermes versions that support skill taps, add the repository as a tap:

hermes skills tap add K-Dense-AI/scientific-agent-skills

Every SKILL.md uses YAML frontmatter with a quoted metadata.version. Repository contributions must use block-style YAML; JSON-style flow mappings fail the reference validator. Optional host-specific configuration belongs under metadata, with host manifest blocks kept as nested mappings. See AGENTS.md for the complete rules. Hosts may interpret optional metadata and credential prompts differently, so verify behavior on the target host. Installing a topical subset keeps the available skill catalog focused on your work.

NemoClaw note: NemoClaw runs agents inside NVIDIA OpenShell with default-deny outbound networking. Skills are discovered and loaded normally, but any skill that needs the network — package installs via uv, or API calls (Exa, Parallel, Benchling, NCBI, Materials Project, …) — only works once the operator pre-approves the relevant domains in the OpenShell TUI.

That's it! A compatible host can discover the skills from its configured paths and use them when relevant. You can also invoke any skill manually by mentioning the skill name in your prompt.

Skills can execute code and influence your coding agent's behavior. Review what you install.

Agent Skills are powerful — they can instruct your AI agent to run arbitrary code, install packages, make network requests, and modify files on your system. A malicious or poorly written skill has the potential to steer your coding agent into harmful behavior.

We take security seriously. All contributions go through a review process, and we run LLM-based security scans (via Cisco AI Defense Skill Scanner) on every skill in this repository. However, as a small team with a growing number of community contributions, we cannot guarantee that every skill has been exhaustively reviewed for all possible risks.

It is ultimately your responsibility to review the skills you install and decide which ones to trust.

We recommend the following:

• Do not install everything at once. Only install the skills you actually need for your work. While installing the full collection was reasonable when K-Dense created and maintained every skill, the repository now includes many community contributions that we may not have reviewed as thoroughly.
• Read the SKILL.md before installing. Each skill's documentation describes what it does, what packages it uses, and what external services it connects to. If something looks suspicious, don't install it.
• Check the contribution history. Skills authored by K-Dense (K-Dense-AI) have been through our internal review process. Community-contributed skills have been reviewed to the best of our ability, but with limited resources.
• Run the security scanner yourself. Before installing third-party skills, scan them locally:

  uv pip install cisco-ai-skill-scanner
  skill-scanner scan /path/to/skill --use-behavioral

• Report anything suspicious. If you find a skill that looks malicious or behaves unexpectedly, please open an issue immediately so we can investigate.

Skills are scanned weekly — incrementally, so unchanged skills carry their previous findings forward, with a full rescan of everything at least every 30 days and whenever the scanner or model changes — and the results are published to docs/security-report.md. See SECURITY.md for our security policy, what is in scope, how to report a vulnerability privately, and how to contest a scan finding. We try to address security gaps as they arise.

Scientific Agent Skills is powered by 50+ incredible open source projects maintained by dedicated developers and research communities worldwide. Projects like Biopython, Scanpy, RDKit, scikit-learn, PyTorch Lightning, and many others form the foundation of these skills.

If you find value in this repository, please consider supporting the projects that make it possible:

• ⭐ Star their repositories on GitHub
• 💰 Sponsor maintainers via GitHub Sponsors or NumFOCUS
• 📝 Cite projects in your publications
• 💻 Contribute code, docs, or bug reports

👉 View the full list of projects to support

• Python: 3.13+ for repository tooling; individual skill dependencies may support broader Python ranges
• uv: Python package manager (required for installing skill dependencies)
• Client: Any agent that supports the Agent Skills standard (Cursor, Claude Code, Gemini CLI, Codex, Google Antigravity, etc.)
• System: macOS, Linux, or Windows with WSL2
• Dependencies: Follow each skill's compatibility field and setup instructions for packages, system tools, credentials, and network access. Installing the skill files does not install their dependencies

Use a separate environment for each scientific workflow: some skills require different Python versions or incompatible package pins. uv sync installs the repository's development and validation tools, not every scientific package in the collection.

The skills use uv as the package manager for installing Python dependencies. Install it using the instructions for your operating system:

macOS and Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh

Windows:

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Alternative (via pip):

pip install uv

After installation, verify it works by running:

uv --version

For more installation options and details, visit the official uv documentation.

Once you've installed the skills, you can ask your AI agent to execute complex multi-step scientific workflows. Here are some example prompts:

Goal: Prioritize EGFR inhibitor candidates for preclinical lung-cancer research

This repository contains 177 scientific and research skills organized across multiple domains. Each skill provides comprehensive documentation, code examples, and best practices for working with scientific libraries, databases, and tools.

Note: The Python package and integration skills listed below are explicitly defined skills — curated with documentation, examples, and best practices for stronger, more reliable performance. They are not a ceiling: the agent can install and use any Python package or call any API, even without a dedicated skill. The skills listed simply make common workflows faster and more dependable.

Categories overlap: a skill may appear in more than one domain, so the category counts do not sum to the 177 unique skills.

• Ontology identifiers: Ontology Term Resolution (resolve free-text tissue, cell-type, disease, phenotype, assay, chemical, organism, and developmental-stage labels to term IDs and validate CURIEs against EBI OLS4, for GEO/ENA/BioSamples/CELLxGENE/HCA/ISA-Tab metadata)
• Live pathogen surveillance: Pathogen Variant Surveillance (which viral lineages are circulating now, how fast they are growing, and what mutations they carry — SARS-CoV-2, influenza including H5N1, RSV, mpox, measles, dengue and more through the GenSpectrum LAPIS API, with lineage names resolved against the live pango-designation nomenclature and reporting lag measured rather than assumed)

• Cloud compute: Modal
• Data distribution and provenance: DataLad (clone and fetch OpenNeuro, DANDI and registry.datalad.org datasets over git-annex, capture re-executable provenance with datalad run/rerun and containers-run, publish to siblings)

• Analytical method validation: plan, evaluate, and document validation, verification, and transfer of analytical procedures (HPLC, LC-MS/MS, GC, CE, ICP-MS, dissolution, qNMR, qPCR, NIR, ligand-binding and cell-based assays) under whichever framework governs — ICH Q2(R2)/Q14 and ICH M10 encoded from their openly licensed text, with USP <1220>/<1225>/<1226>, the CLSI EP series, and ISO/IEC 17025 cited by designation and scope only; stdlib-only statistics, no network access
• Assurance-lane separation: keeps ISO certification, laboratory accreditation, FDA QMSR inspection, CLIA certification, MDSAP, and EU MDR/IVDR evidence boundaries distinct—laboratories are accredited rather than certified, and ISO 15189 accreditation does not satisfy CLIA
• Never a compliance, audit, assessment, certification, accreditation, or method-release decision; qualified RA/QA, legal, laboratory-director, assessor, and certification-body review is required

Deep dives, benchmarks, and guides from the K-Dense blog that are directly relevant to using the skills in this repository.

• Agent Skills: The Final Piece for AI-Powered Scientific Research — What Agent Skills are, why curated domain guidance beats raw model capability, and an introduction to this repository.
• K-Dense Web vs Scientific Agent Skills: Why We Built Both (And Which One You Should Use) — When the open-source skills are the right tool, and when a hosted platform with managed compute makes more sense.
• AI Co-Scientists, Answered: 20 Questions from a Live Session with a University Research Center — Practical questions from a research center evaluating AI co-scientists: what stays open source and MIT-licensed, how local and desktop deployments work, how data is handled, and how to choose between the hosted platform and the BYOK setup that runs these skills.
• How to Use Multica for Scientific Research — A self-hosted Multica workspace plus a curated subset of these skills: clinical-trial and variant analyses, literature review, weekly autopilots, and a second-model audit, with each skill imported from skills/<name>/.

• The Silent 97%: Introducing the waypoint-bio Agent Skill — waypoint-bio against silent data loss: an unconverted MetaPhlAn table keeps 3% of abundance mass and still returns a valid embedding; skill-equipped agents won 16 to 0 on matched pairs.
• The Millimetre Problem: Introducing the lab-hardware-cad Agent Skill — lab-hardware-cad over 98 geometry-scored runs: the skill arm produced parametric, regenerable models in 49 of 49 cases (baseline 0 of 49) and named the missing Y-maze standard instead of inventing one.
• One Skill, 78 Databases: Why We Didn't Build 78 Skills — The design rationale behind database-lookup: consolidation cut always-on context cost by 13.9x while holding routing accuracy across five models.
• Can an AI Agent Run Your Mass Spec Pipeline? Benchmarking the PyOpenMS Skill — A 250-run study of pyopenms: 100% task success with the skill versus 96% without, 92% fewer pyOpenMS API errors, and 10% lower cost.
• Beyond RDKit: Benchmarking the Rowan Agent Skill Against Experiment — rowan compared against RDKit and experimental data: pKa MAE 0.23 (R² 0.986), logD₇.₄ MAE 1.15, and 0.19 Å RMSD docking pose recovery for roughly $0.52 of compute.
• GPU-Accelerate Your Science: 58x Average Speedup with a Single Skill — optimize-for-gpu rewriting CPU-bound Python across 12 libraries, with speedups ranging from 1.7x to 492x.
• Towards Smarter Scientific Search: Exa Joins the Scientific Agent Skills Library — What exa-search adds: neural semantic search and URL extraction tuned for scholarly discovery instead of keyword matching.
• Benchmarking Nano Banana 2 Lite for Scientific Image Generation — A 240-image comparison of scientific-diagram models, useful when choosing a backend for generate-image: 3.8 s median latency for Nano Banana 2 Lite against 49 s for GPT Image 2, with a quality tradeoff.
• Benchmarking NVIDIA BioNeMo Agent Toolkit Skills for NIM microservices — A separate NVIDIA skill set rather than one of these, but the findings generalize: skills help most with routing to non-obvious endpoints and with weak-model reliability, and do not improve the underlying scientific model's accuracy.

• The Model Is No Longer the Bottleneck — The case for why a repository like this one exists: frontier models now match specialized scientific software on raw capability (±0.079 ppm on NMR hydrogen shift prediction), so the limiting factor has moved to the workflow around the model — data access, code execution, verification, and auditable output.
• The AI Co-Scientist Is Here. The Bottleneck Is Verification. — A 10-point checklist for evaluating a research agent, built around exposing sources, code, data provenance, and intermediate work rather than a polished final answer — the same reasoning behind the provenance and retrieval-contract requirements in skills like database-lookup and scientific-writing.
• Reproduction, Not Generation, Is AI's Killer App for Science — Why re-running published analyses is the highest-value use of an agent: 78% of papers and 93% of individual analysis tasks reproduced across a 221-study benchmark, because a reproduction can be checked against known numbers while a generated claim cannot.
• Introducing K-Bench 01: Nine Frontier Models, 178 Real Scientific Tasks, and a Lot of Confident Wrong Answers — Nine frontier models on 178 real user tasks, with overclaiming in 40% of runs. Useful calibration for what to check when an agent reports success, and context for the verification boundaries written into the clinical, regulatory, and research-methodology skills above.

• Security in the Science Agent Era: What Every Lab Needs to Know Before Installing Skills — The practical review checklist behind this repo's Security Disclaimer: read the full SKILL.md and scripts/, scan before installing, and pin versions instead of tracking a branch.

We welcome contributions to expand and improve this scientific skills repository!

Read AGENTS.md before creating or changing a skill, and see CONTRIBUTING.md for the detailed workflow and pull request process. Contributions should focus on a scientific package, database, platform, or research workflow; broad coding, infrastructure, and routing skills are outside the repository's scope.

🐛 Report Issues

• Submit bug reports with detailed reproduction steps
• Suggest improvements or new features

1. Fork the repository
2. Create a feature branch (git checkout -b feature/amazing-skill)
3. Follow CONTRIBUTING.md and the existing directory structure
4. Ensure all new skills include valid SKILL.md files with required frontmatter and metadata.version
5. Test your examples and workflows thoroughly, and add a suite under tests/<skill-name>/ if your skill ships scripts/
6. Commit your changes (git commit -m 'Add amazing skill')
7. Push to your branch (git push origin feature/amazing-skill)
8. Submit a pull request with a clear description of your changes

✅ Adhere to the Agent Skills Specification — Every skill must follow the official spec (valid SKILL.md frontmatter, naming conventions, directory structure)
✅ Include a quoted metadata.version value in every SKILL.md
✅ Increment metadata.version when updating an existing skill
✅ Maintain consistency with existing skill documentation format
✅ Ensure all code examples are tested and functional
✅ Follow scientific best practices in examples and workflows
✅ Update relevant documentation when adding new capabilities
✅ Provide clear comments and docstrings in code
✅ Include references to official documentation

Every skill that ships scripts/ must have a test suite under tests/<skill-name>/ and an entry in tests/skill-requirements.toml. The tests/_meta guard checks this coverage and the shared structural contract: frontmatter, document length, local links, script syntax, bytecode, and hardcoded local paths. It also validates plugin.json against the bundled Agent Plugins schema and checks that its version matches pyproject.toml. CLI --help and worked-example execution checks belong to the individual skill suites.

# Install repository development and validation tools
uv sync

# Structural contract and coverage guard — seconds, no scientific packages needed
uv run python -m pytest tests/_meta -q

# Validate one skill's Agent Skills frontmatter
uv run skills-ref validate skills/<skill-name>

# One skill's suite in the current environment
uv run --with pytest python -m pytest tests/<skill-name> -q

# One skill with its declared packages and Python version
uv run python tests/run_all.py --isolated <skill-name>

# Every suite, each in its own throwaway environment
uv run python tests/run_all.py --isolated

Run one skill per pytest process: different skills reuse module names such as _common, so collecting several suites together can import the wrong module. tests/run_all.py handles process isolation; --isolated also provides each skill's declared dependency environment. A suite run in the current environment may skip checks when required packages are absent.

The Skill Tests workflow runs the contract and standard-library-only suites for relevant pull requests and pushes to main, and can be triggered manually. The full scientific dependency sweep is not run in CI; run it before a release or when changing the shared contract. Some skills need external runtimes or system tools; installation gaps are documented in tests/skill-requirements.toml.

All skills in this repository are security-scanned using Cisco AI Defense Skill Scanner, an open-source tool that detects prompt injection, data exfiltration, and malicious code patterns in Agent Skills.

If you are contributing a new skill, we recommend running the scanner locally before submitting a pull request:

uv pip install cisco-ai-skill-scanner
skill-scanner scan /path/to/your/skill --use-behavioral

Note: A clean scan result reduces noise in review, but does not guarantee a skill is free of all risk. Contributed skills are also reviewed manually before merging.

Q: Is this free to use?
A: Yes! This repository is MIT licensed. However, each individual skill has its own license specified in the license metadata field within its SKILL.md file—be sure to review and comply with those terms.

Q: Why are all skills grouped together instead of separate packages?
A: We believe good science in the age of AI is inherently interdisciplinary. Bundling all skills together makes it trivial for you (and your agent) to bridge across fields—e.g., combining genomics, cheminformatics, clinical data, and machine learning in one workflow—without worrying about which individual skills to install or wire together.

Q: Can I use this for commercial projects?
A: The repository itself is MIT licensed, which allows commercial use. However, individual skills may have different licenses—check the license field in each skill's SKILL.md file to ensure compliance with your intended use.

Q: Do all skills have the same license?
A: No. Each skill has its own license specified in the license metadata field within its SKILL.md file. These licenses may differ from the repository's MIT License. Users are responsible for reviewing and adhering to the license terms of each individual skill they use.

Q: How often is this updated?
A: We regularly update skills to reflect the latest versions of packages and APIs. Major updates are announced in release notes.

Q: Can I use this with other AI models?
A: The core SKILL.md format follows the open Agent Skills standard. Installation paths, discovery, and optional metadata support vary by host and version, so confirm your target host's current documentation.

Q: Do I need all the Python packages installed?
A: No. Install only the dependencies for the workflows you use, following each SKILL.md. Keep workflows with incompatible package or Python requirements in separate environments.

Q: What if a skill doesn't work?
A: First check the Troubleshooting section. If the issue persists, file an issue on GitHub with detailed reproduction steps.

Q: Do the skills work offline?
A: Local analysis can work offline once its dependencies, reference data, and model files are available. Database queries, hosted models, and cloud platforms need network access; check the individual skill's requirements.

Q: Can I contribute my own skills?
A: Absolutely! We welcome contributions. See the Contributing section for guidelines and best practices.

Q: How do I report bugs or suggest features?
A: Open an issue on GitHub with a clear description. For bugs, include reproduction steps and expected vs actual behavior.
