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 6d ago.

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.
