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// and a dependency entry in tests/skill-requirements.toml.

What's new in 2.72.0

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.

What's new in 2.71.0

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.

🎯 Getting Started

Option 1: npx (supported hosts)

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.

Option 2: GitHub CLI (gh skill)

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.

Version pinning

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

Keeping skills up to date

# Check for updates interactively
gh skill update
Update all installed skills
gh skill update --all

Option 3: Agent Plugins (Cursor, Codex, and other plugin clients)

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.

Other Agent Skills hosts (OpenClaw, NemoClaw, Pi, Hermes, …)

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 t
