pytdc

pytdc is a skill for Claude Code, Codex from synthetic-sciences/openscience. It costs 41 tokens per session (3,096 once invoked), scanned A, original, Apache-2.0.

A Python toolkit of curated datasets and benchmarks for machine-learning work in drug discovery. It covers tasks such as predicting molecule properties, drug interactions, and generating new molecules.

In plain words
What is it for?
Use it to train or benchmark models for ADME, toxicity, bioactivity, drug-target interactions, drug-drug interactions, and molecule generation.
Why use it?
It provides consistent data splits and evaluation methods, making therapeutic machine-learning results easier to compare and reproduce.

About the project

synthetic-sciences/openscience is an AI workbench that carries out scientific research by reading papers, forming hypotheses, writing and running code, conducting experiments, analyzing results, and preparing reports. Researchers use it for work in machine learning, biology, physics, and chemistry with remote or local models. Catalogue add-ons extend its scientific workflows through skills and instructions.

Token cost

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.

Security

Grade A, and why

pytdc 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 yesterday.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/benchmark_evaluation.py, scripts/load_and_split_data.py, scripts/molecular_generation.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

PyTDC (Therapeutics Data Commons)

Overview

PyTDC is an open-science platform providing AI-ready datasets and benchmarks for drug discovery and development. Access curated datasets spanning the entire therapeutics pipeline with standardized evaluation metrics and meaningful data splits, organized into three categories: single-instance prediction (molecular/protein properties), multi-instance prediction (drug-target interactions, DDI), and generation (molecule generation, retrosynthesis).

When to Use This Skill

This skill should be used when:

  • Working with drug discovery or therapeutic ML datasets
  • Benchmarking machine learning models on standardized pharmaceutical tasks
  • Predicting molecular properties (ADME, toxicity, bioactivity)
  • Predicting drug-target or drug-drug interactions
  • Generating novel molecules with desired properties
  • Accessing curated datasets with proper train/test splits (scaffold, cold-split)
  • Using molecular oracles for property optimization

Installation & Setup

Install PyTDC using pip:

uv pip install PyTDC

To upgrade to the latest version:

uv pip install PyTDC --upgrade

Core dependencies (automatically installed):

  • numpy, pandas, tqdm, seaborn, scikit_learn, fuzzywuzzy

Additional packages are installed automatically as needed for specific features.

Quick Start

The basic pattern for accessing any TDC dataset follows this structure:

from tdc.<problem> import <Task>
data = <Task>(name='<Dataset>')
split = data.get_split(method='scaffold', seed=1, frac=[0.7, 0.1, 0.2])
df = data.get_data(format='df')

Where:

  • <problem>: One of single_pred, multi_pred, or generation
  • <Task>: Specific task category (e.g., ADME, DTI, MolGen)
  • <Dataset>: Dataset name within that task

Example - Loading ADME data:

from tdc.single_pred import ADME
data = ADME(name='Caco2_Wang')
split = data.get_split(method='scaffold')
# Returns dict with 'train', 'valid', 'test' DataFrames

What ships with it

6 files 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.

Changes

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.

pytdc is a skill published in the GitHub repository synthetic-sciences/openscience (3,473 stars, last pushed today), licensed Apache-2.0. It adds 41 tokens to every session and 3,096 once invoked, about $0.0002 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 2026-09-03.
