What it does

Rowan is an agent skill from K-Dense-AI/scientific-agent-skills. Rowan is a cloud-native molecular modeling and medicinal-chemistry workflow platform with a Python API. Use for pKa and macropKa prediction, conformer and tautomer ensembles, docking and analogue docking, protein-ligand cofolding, MSA generation, molecular dynamics, permeability, descriptor workflows, and related small-molecule or protein modeling tasks. Ideal for programmatic batch screening, multi-step chemistry pipelines, and workflows that would otherwise require maintaining local HPC/GPU infrastructure.

Its SKILL.md is about 4.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `references/access_and_pricing.md`, `references/batch_and_webhooks.md` and `references/end_to_end_example.md`). Compatibility notes: Python 3.12+ with rowan-python and its RDKit/stjames dependencies. Requires network access and ROWANAPIKEY for hosted workflows.

It sits in Research & Science, covering Drug discovery and cheminformatics and Physical and earth sciences. It works with Python. The repository describes itself as: Turn any AI agent into an AI Scientist. The 1 Agent Skills library for science, used by 250,000+ scientists worldwide. 177 ready-to-use validated skills plus 100+ scientific…

When your agent uses it

  • PKa and macropKa prediction
  • Conformer and tautomer ensembles
  • Docking and analogue docking
  • Protein-ligand cofolding

Example prompts

  • “/rowan”

Requirements

  • Python 3
  • A credential in ROWAN_API_KEY
  • Compatibility (from SKILL.md): Python 3.12+ with rowan-python and its RDKit/stjames dependencies. Requires network access and ROWAN_API_KEY for hosted workflows.

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Submit a workflow
  2. Wait for completion (with optional streaming)
  3. Retrieve typed results with convenience properties

What it can do on your machine

Read from SKILL.md and the folder at commit 92ace75. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • pypi.org
    • docs.rowansci.com
    • rcsb.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • ROWAN_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Python 3.12+ with rowan-python and its RDKit/stjames dependencies. Requires network access and ROWAN_API_KEY for hosted workflows.

    From compatibility in the SKILL.md frontmatter.

Context cost

Rowan loads about 4.3k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 130 tokens; SKILL.md has 1,365 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~130
When it runs · the whole SKILL.md, loaded when a task matches
~4.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~13k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,365 words (~4,326 tokens).

“Rowan is a cloud-native workflow platform for molecular simulation, medicinal chemistry, and structure-based design. Its Python API exposes a unified interface for small-molecule modeling, property prediction, docking, molecular dynamics, and AI structure workflows.”

Can I use Rowan in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add K-Dense-AI/scientific-agent-skills --skill rowan -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/rowan, .gemini/skills/rowan, .github/skills/rowan and .opencode/skills/rowan in your project.

What does Rowan need to run?

Going by SKILL.md and its folder, Rowan needs the command-line tools its instructions call (uv) and credentials named ROWAN_API_KEY. Our summary lists: Python 3; A credential in ROWAN_API_KEY. Compatibility (from SKILL.md): Python 3.12+ with rowan-python and its RDKit/stjames dependencies. Requires network access and ROWAN_API_KEY for hosted workflows..

Does Rowan access the network?

SKILL.md names 3 domains. As links in the text: pypi.org, docs.rowansci.com and rcsb.org. This is read from the text; nothing was executed.

Is Rowan safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Rowan use?

Rowan carries a proprietary licence (declared in SKILL.md). It is published on GitHub, but it is not open source: read the licence file before using or sharing it.

How many tokens does Rowan use?

About 4.3k tokens (SKILL.md is roughly 17k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 8.8k tokens, read only when the agent opens those files.
