Agent Skill
Env Management skill
env-managementaipoch/open-scienceresources/skills/env-management/SKILL.md
Use when a notebook run fails on a missing package (ImportError, ModuleNotFoundError, "there is no package called"), when you need to inspect an installed package version, or when you need to install, add, or manage Python or R packages for the notebook runtime. Covers inspect_packages, routing Python vs R through manage_packages, why in-cell %pip/!pip/install.packages() and OS installers are forbidden, restarting the kernel after an install, and when to stop and ask the user.

Install the Env Management skill
Skills CLI (Claude Code, Codex, Cursor and others)
npx skills add https://github.com/aipoch/open-science --skill env-management
Claude Code, by hand (all projects)
git clone --depth 1 https://github.com/aipoch/open-science.git /tmp/open-science mkdir -p ~/.claude/skills cp -R /tmp/open-science/resources/skills/env-management ~/.claude/skills/env-management
For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.
What it costs your context
Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.
| When | What loads | Cost |
|---|---|---|
| Every session | Name and description | 105 tok |
| When the agent uses it | The SKILL.md instructions | 1,362 tok |
| Only if opened | No bundled files | — |
Until it is used, env-management costs about 13× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 25 skills from aipoch/open-science would load 2,130 tokens of descriptions. Skills vs MCP study

Prepare reproducible setup instructions and validate a user-managed named software environment on an Open-Science SSH Compute Host, including direct SSH and Slurm hosts. Use when a remote job needs packages, modules, cache variables, or a repeatable activation that the host does not already provide.
5.3k61 tok idle · 2,070 in use - customizeaipoch/open-science
Use when the user wants to create or manage a Specialist agent or create, revise, publish, or delete a Skill through the conversational `/Customize` entry. Routes Skill work to the internal skill-creator and handles Specialist work through the JavaScript host.agents SDK.
5.3k56 tok idle · 2,287 in use - diffdockaipoch/open-science
Predict small-molecule binding poses with DiffDock-L (Corso et al. 2023/2024, github.com/gcorso/DiffDock) — blind diffusion docking that places a ligand into a protein pocket without a predefined search box and ranks the samples with a learned confidence model. Reach for this skill to dock a SMILES or SDF against a PDB, to generate ranked 3D poses for a small fragment library, or to get a starting pose for downstream rescoring. DiffDock predicts geometry, not affinity.

FoldBench Ab-Ag 50-55%, PPI 70-77% DockQ-pass. Also covers the ESMC-{300M,600M,6B} protein language models from the same release: masked-LM logits, hidden states, mutation scoring, contact prediction, and the SAE interpretability head. MIT-licensed weights on HuggingFace org `biohub`. Use this skill when: (1) Predicting complex structures with single-sequence input, (2) Validating designed binders with ESMFold2-Fast, (3) Running ESMFold2 with MSA input, (4) Getting ESMC embeddings or per-residue mutation scores, (5) Choosing kernel backend and sampling-step settings for paper-faithful throughput.
