Open Science is a local-first, model-agnostic workbench for reproducible scientific research. Scientists use its AI agents, Python and R execution, data connectors, and traceable outputs for tasks such as literature review, analysis, simulation, and visualization across macOS, Windows, and Linux.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00066 | $0.01396 |
| Opus 5 | $0.00033 | $0.00698 |
| Sonnet 5 | $0.00013 | $0.00279 |
| Haiku 4.5 | $0.00007 | $0.00140 |
Grade A, and why
fair-esm2 scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts
The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
fair-esm2 — ESM-2 (Meta AI)
ESM-2 code and weights are MIT (Meta AI, github.com/facebookresearch/esm).
Package disambiguation.
pip install fair-esmgives youimport esmwithesm.pretrained.*(ESM-1/2). Biohub's github.com/Biohub/esm fork (MIT) gives youfrom esm.models.esmfold2 import ESMFold2InputBuilder— see theesmfold2skill. Both share theesmnamespace but are different libraries. This skill covers fair-esm (the Meta package).
Prerequisites
| Requirement | Minimum | Recommended |
|---|---|---|
| Python | 3.8+ | 3.11 |
| CUDA | 11.7+ | 12.x |
| GPU VRAM | 8 GB (8M), 16 GB (650M) | 24 GB+ (650M / 3B) |
How to run
Embeddings
import torch, esm
model, alphabet = esm.pretrained.esm2_t33_650M_UR50D()
model = model.eval().cuda()
bc = alphabet.get_batch_converter()
_, _, toks = bc([("ubq", "MQIFVKTLTGKTITLEVEPSDTIENVK")])
with torch.no_grad():
out = model(toks.cuda(), repr_layers=[33])
emb = out["representations"][33] # (1, L+2, 1280) — includes BOS/EOS
seq_emb = emb[0, 1:-1].mean(0) # per-sequence mean
Masked-LM scoring
with torch.no_grad():
out = model(toks.cuda(), repr_layers=[33])
logits = out["logits"][0, 1:-1] # (L, |vocab|)
# WT marginal log-likelihood; for mutation scoring, mask the position and
# compare logit[mut] − logit[wt].
Contact prediction
with torch.no_grad():
out = model(toks.cuda(), repr_layers=[33], return_contacts=True)
contacts = out["contacts"][0] # (L, L)
Models

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 8d ago First seen · 139 lines · 66 tokens per session scan A 943aa46d306f
fair-esm2 is a skill published in the GitHub repository aipoch/open-science (3,964 stars, last pushed today), licensed Apache-2.0. It adds 66 tokens to every session and 1,396 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
build-paper-pipeline
Build the pipeline stages a manuscript's TODO comments ask for.
check-questions
Review a Calkit project's questions and answers against their evidence. Use when the user invokes /calkit:check-questions, asks whether the project's answers are still true, or after a pipeline run changes results that answers cite.
clinical-case-report
Structured medical case presentation for clinical rounds, conferences, and documentation. Generates SOAP-format or narrative case reports with physiologically accurate vitals, labs, and evidence-based plans. Use when the brief mentions "case report", "case presentation", "SOAP note", "clinical case", "ward rounds"…
proof-checker
A mathematical proof review and repair workflow for LaTeX documents. It checks whether a proof has valid reasoning, addresses identified gaps, reviews the fixes, and produces an audit report.
paper-illustration
A workflow for generating academic illustrations, such as architecture diagrams and method visuals, with image generation and repeated review. Claude plans and checks the figure during the process.
paper-illustration-image2
Generate publication-quality academic illustrations through a local Codex app-server bridge that uses Codex native image generation. This is a separate experimental alternative to paper-illustration, intended for Claude Code users who want a GPT-image-style renderer without modifying the original skill.
