 # PyTDC (Therapeutics Data Commons)
 
-## Overview
+Use the official `PyTDC` distribution (`import tdc`) to discover therapeutic ML
+tasks, load approved datasets, apply task-appropriate splits, evaluate predictions,
+and work with curated benchmark groups. Prefer package metadata over copied dataset
+lists, and plan network/storage effects before constructing any loader.
 
-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).
+## Verified snapshot
 
-## When to Use This Skill
+- Research date: **2026-07-23**
+- PyPI stable: **PyTDC 1.1.15**, released 2025-03-31
+- Package/source repository: `mims-harvard/TDC`
+- Code license: MIT
+- PyPI supplies only a source distribution and declares no `Requires-Python`
+- The dependency graph makes **CPython 3.11** the reproducible target used here:
+  `cellxgene-census==1.15.0` excludes Python 3.12, and PyTDC's constrained
+  RDKit release has no CPython 3.13 wheel
+- PyTDC imports deprecated `pkg_resources` at runtime. Setuptools 82 removed that
+  module; pin the verified compatibility release **setuptools 80.9.0**.
+- `tdc.readthedocs.io` still identifies itself as TDC 0.4.1; use it as API
+  cross-reference, not as release-version evidence
+- Upstream publishes no GitHub tags/releases or maintained changelog. Treat
+  undocumented migration claims as uncertainty and verify against the installed
+  1.1.15 source/metadata.
 
-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
+See [references/sources.md](references/sources.md) for dated evidence and known
+documentation conflicts.
 
-## Installation & Setup
+## Installation
 
-Install PyTDC using pip:
+Use an isolated CPython 3.11 environment and pin the reviewed snapshot:
 
 ```bash
-uv pip install PyTDC
+uv venv --python 3.11 .venv-pytdc
+uv pip install --dry-run --python .venv-pytdc/bin/python \
+  "setuptools==80.9.0" "PyTDC==1.1.15"
+uv pip install --python .venv-pytdc/bin/python \
+  "setuptools==80.9.0" "PyTDC==1.1.15"
 ```
 
-To upgrade to the latest version:
+The tested macOS ARM64 resolution installed 123 packages, including large
+scientific/ML dependencies, so the environment itself can transfer and occupy
+hundreds of megabytes before any dataset is downloaded. Review the dry run and
+available disk first. The direct pins identify the reviewed API snapshot; generate
+a platform-specific `uv.lock` in the user's project when every transitive version
+must also be frozen.
+
+For an ephemeral command:
 
 ```bash
-uv pip install PyTDC --upgrade
+uv run --python 3.11 \
+  --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
+  python scripts/discover_metadata.py --kind tasks
 ```
 
-Core dependencies (automatically installed):
-- numpy, pandas, tqdm, seaborn, scikit_learn, fuzzywuzzy
+To check for a newer release, inspect the PyPI release history at
+<https://pypi.org/project/pytdc/>. Before changing the pin, compare its source
+distribution, dependencies, official repository, task registries, and smoke tests;
+do not silently substitute the separate `pytdc-nextml` package.
 
-Additional packages are installed automatically as needed for specific features.
+## Non-negotiable data and network policy
 
-## Quick Start
+1. **Discover first.** Reading `tdc.metadata` or using
+   `scripts/discover_metadata.py` does not instantiate a loader or download data.
+2. **Plan second.** Record the exact task/dataset, official task page, license,
+   expected size, cache directory, split, metric, and reproducibility seed.
+3. **Ask the user before downloading.** Loader constructors fetch missing data.
+   Some datasets and benchmark-group archives are large; model-backed oracles can
+   fetch checkpoints; remote/docking oracles can transmit molecular structures.
+4. **Execute only after approval.** In bundled CLIs, `--execute` acknowledges
+   execution and `--download` is additionally required for MolGen corpora or
+   supported oracle checkpoints.
+5. **Keep outputs bounded.** Emit counts, schema, and small previews rather than
+   full datasets, sequences, prediction arrays, or molecule corpora.
 
-The basic pattern for accessing any TDC dataset follows this structure:
+### Cache and cost behavior
+
+- Ordinary loaders default to `path="./data"` and save files beneath that path.
+  The bundled scripts instead default to explicit `.pytdc-*` directories.
+- Core downloads use Harvard Dataverse file endpoints when a local filename is
+  absent. Newer resource classes may use other upstream services.
+- `admet_group(path=...)` and other benchmark-group constructors download and
+  extract the group archive when `<path>/<group>` is absent.
+- Download-backed `Oracle(...)` construction uses `./oracle` internally. The
+  bundled oracle CLI changes into a safe runtime directory before approved calls.
+- PyTDC 1.1.15 does not provide a universal cache quota, eviction policy, or
+  dataset-wide checksum manifest. Use `scripts/cache_audit.py` and manage disk
+  retention explicitly.
+- Network transfer, local storage, decompression, parsing, feature generation,
+  docking, and external service calls can all incur time or monetary cost.
+
+The PyTDC **code** is MIT. Dataset/task licenses are heterogeneous: official task
+pages include per-dataset terms ranging from Creative Commons licenses to
+non-commercial restrictions or “Not Specified.” Verify the exact dataset's page and
+original source terms before download, redistribution, publication, or commercial
+use. Cite both TDC and the original dataset.
+
+## Start with metadata-only discovery
+
+From this skill directory:
+
+```bash
+uv run --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
+  python scripts/discover_metadata.py --kind datasets --task ADME --limit 50
+
+uv run --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
+  python scripts/discover_metadata.py --kind benchmarks --limit 50
+
+uv run --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
+  python scripts/discover_metadata.py --kind evaluators --limit 100
+```
+
+The package API is also metadata-only:
 
 ```python
-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')
+from tdc.utils import retrieve_dataset_names, retrieve_benchmark_names
+
+adme_names = retrieve_dataset_names("ADME")
+admet_benchmarks = retrieve_benchmark_names("admet_group")
 ```
 
-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
+Use exact returned names. PyTDC performs fuzzy matching internally, but explicit
+matching avoids silently selecting the wrong dataset/oracle.
 
-**Example - Loading ADME data:**
+## Dataset workflow
+
+Plan a split without downloading:
+
+```bash
+uv run --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
+  python scripts/load_and_split_data.py \
+  --task ADME --dataset Caco2_Wang --method scaffold \
+  --seed 42 --data-dir .pytdc-data
+```
+
+After the user approves the dataset, license, transfer, and storage:
+
+```bash
+uv run --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
+  python scripts/load_and_split_data.py \
+  --task ADME --dataset Caco2_Wang --method scaffold \
+  --seed 42 --data-dir .pytdc-data --execute
+```
+
+Verified public import patterns include:
 
 ```python
-from tdc.single_pred import ADME
-data = ADME(name='Caco2_Wang')
-split = data.get_split(method='scaffold')
-# Returns dict with 'train', 'valid', 'test' DataFrames
+from tdc.single_pred import ADME, Tox
+from tdc.multi_pred import DDI, DTI
+from tdc.generation import MolGen, Reaction, RetroSyn
 ```
 
-## Single-Instance Prediction Tasks
-
-Single-instance prediction involves forecasting properties of individual biomedical entities (molecules, proteins, etc.).
-
-### Available Task Categories
-
-#### 1. ADME (Absorption, Distribution, Metabolism, Excretion)
-
-Predict pharmacokinetic properties of drug molecules.
+Constructors perform data access, so do not run them before approval:
 
 ```python
-from tdc.single_pred import ADME
-data = ADME(name='Caco2_Wang')  # Intestinal permeability
-# Other datasets: HIA_Hou, Bioavailability_Ma, Lipophilicity_AstraZeneca, etc.
+data = ADME(name="Caco2_Wang", path=".pytdc-data")
+frame = data.get_data(format="df")
+split = data.get_split(
+    method="scaffold",
+    seed=42,
+    frac=[0.7, 0.1, 0.2],
+)
+# split keys are: train, valid, test
 ```
 
-**Common ADME datasets:**
-- Caco2 - Intestinal permeability
-- HIA - Human intestinal absorption
-- Bioavailability - Oral bioavailability
-- Lipophilicity - Octanol-water partition coefficient
-- Solubility - Aqueous solubility
-- BBB - Blood-brain barrier penetration
-- CYP - Cytochrome P450 metabolism
+Read [references/datasets.md](references/datasets.md) before choosing a task or
+dataset.
 
-#### 2. Toxicity (Tox)
+## Split selection without overclaiming leakage control
 
-Predict toxicity and adverse effects of compounds.
+- `random`: default for loaders; default seed 42 and fractions 0.7/0.1/0.2.
+- `scaffold`: documented generic support for molecule-based ADME, Tox, and HTS.
+  PyTDC groups RDKit Bemis–Murcko scaffold strings (chirality disabled), but that
+  does **not** prove absence of analog, duplicate, label, temporal, or provenance
+  leakage.
+- `cold_split`: multi-instance API. Pass exact dataframe columns, for example
+  `method="cold_split", column_name=["Drug", "Target"]`. Multi-column splitting can
+  discard cross-partition rows and need not preserve requested row fractions.
+- `combination`: built-in DrugSyn combination split.
+- `time`: pair-loader API requiring `time_column`; the verified built-in case is
+  `BindingDB_Patent` with its `Year` column. The API spelling is `time`, not
+  `temporal`.
+
+Do not use undocumented `cold_drug_target`, `temporal`, or `stratified=True`
+examples. For every split, record PyTDC version, parameters, row counts, and exact
+entity overlap audits. PyTDC 1.1.15's random splitter uses the supplied seed for
+test sampling but a fixed `random_state=1` for validation sampling; do not describe
+all partitions as independently varying with the seed.
+
+Detailed semantics and caveats are in
+[references/utilities.md](references/utilities.md).
+
+## Evaluators
+
+Use exact names from the installed evaluator registry:
 
 ```python
-from tdc.single_pred import Tox
-data = Tox(name='hERG')  # Cardiotoxicity
-# Other datasets: AMES, DILI, Carcinogens_Lagunin, etc.
+from tdc import Evaluator
+
+mae = Evaluator(name="MAE")(y_true, y_pred)
+auroc = Evaluator(name="ROC-AUC")(y_true_binary, predicted_scores)
+pcc = Evaluator(name="PCC")(y_true, y_pred)
 ```
 
-**Common toxicity datasets:**
-- hERG - Cardiac toxicity
-- AMES - Mutagenicity
-- DILI - Drug-induced liver injury
-- Carcinogens - Carcinogenicity
-- ClinTox - Clinical trial toxicity
+`PCC` is the registered Pearson-correlation name; `Pearson` is not. Multi-class
+registry names are `micro-f1`, `macro-f1`, and `kappa`. Thresholded binary metrics
+default to 0.5. Metric direction and input shape are metric-specific; use the
+official task/benchmark metric rather than choosing from task type alone.
 
-#### 3. HTS (High-Throughput Screening)
+## Benchmark groups
 
-Bioactivity predictions from screening data.
-
-```python
-from tdc.single_pred import HTS
-data = HTS(name='SARSCoV2_Vitro_Touret')

-#### 4. QM (Quantum Mechanics)
-
-Quantum mechanical properties of molecules.

-- **Develop**: Development-stage predictions
-- **CRISPROutcome**: Gene editing outcome prediction
-
-### Data Format
-
-Single prediction datasets typically return DataFrames with columns:
-- `Drug_ID` or `Compound_ID`: Unique identifier
-- `Drug` or `X`: SMILES string or molecular representation
-- `Y`: Target label (continuous or binary)
-
-## Multi-Instance Prediction Tasks
-
-Multi-instance prediction involves forecasting properties of interactions between multiple biomedical entities.
-
-### Available Task Categories
-
-#### 1. DTI (Drug-Target Interaction)
-
-Predict binding affinity between drugs and protein targets.
-
-```python
-from tdc.multi_pred import DTI
-data = DTI(name='BindingDB_Kd')
-split = data.get_split()
-```
-
-**Available datasets:**
-- BindingDB_Kd - Dissociation constant (52,284 pairs)
-- BindingDB_IC50 - Half-maximal inhibitory concentration (991,486 pairs)
-- BindingDB_Ki - Inhibition constant (375,032 pairs)
-- DAVIS, KIBA - Kinase binding datasets
-
-**Data format:** Drug_ID, Target_ID, Drug (SMILES), Target (sequence), Y (binding affinity)

-data = PPI(name='HuRI')
-```
-
-#### 4. Other Multi-Prediction Tasks

-- **DrugRes**: Drug resistance prediction
-- **DrugSyn**: Drug synergy prediction
-- **PeptideMHC**: Peptide-MHC binding
-- **AntibodyAff**: Antibody affinity prediction
-- **MTI**: miRNA-target interactions
-- **Catalyst**: Catalyst prediction
-- **TrialOutcome**: Clinical trial outcome prediction
-
-## Generation Tasks
-
-Generation tasks involve creating novel biomedical entities with desired properties.
-
-### 1. Molecular Generation (MolGen)
-
-Generate diverse, novel molecules with desirable chemical properties.
-
-```python
-from tdc.generation import MolGen
-data = MolGen(name='ChEMBL_V29')
-split = data.get_split()
-```
-
-Use with oracles to optimize for specific properties:
-
-```python
-from tdc import Oracle
-oracle = Oracle(name='GSK3B')
-score = oracle('CC(C)Cc1ccc(cc1)C(C)C(O)=O')  # Evaluate SMILES
-```
-
-See `references/oracles.md` for all available oracle functions.
-
-### 2. Retrosynthesis (RetroSyn)
-
-Predict reactants needed to synthesize a target molecule.
-
-```python
-from tdc.generation import RetroSyn
-data = RetroSyn(name='USPTO')
-split = data.get_split()
-```
-
-Dataset contains 1,939,253 reactions from USPTO database.
-
-### 3. Paired Molecule Generation
-
-Generate molecule pairs (e.g., prodrug-drug pairs).
-
-```python
-from tdc.generation import PairMolGen
-data = PairMolGen(name='Prodrug')
-```
-
-For detailed oracle documentation and molecular generation workflows, refer to `references/oracles.md` and `scripts/molecular_generation.py`.
-
-## Benchmark Groups
-
-Benchmark groups provide curated collections of related datasets for systematic model evaluation.
-
-### ADMET Benchmark Group
+Use specialized classes. Top-level `from tdc import BenchmarkGroup` is retained
+only as a deprecated compatibility path in 1.1.15.
 
 ```python
 from tdc.benchmark_group import admet_group
-group = admet_group(path='data/')
 
-# Get benchmark datasets
-benchmark = group.get('Caco2_Wang')
-predictions = {}
-
-for seed in [1, 2, 3, 4, 5]:
-    train, valid = benchmark['train'], benchmark['valid']
-    # Train model here
-    predictions[seed] = model.predict(benchmark['test'])
-
-# Evaluate with required 5 seeds
-results = group.evaluate(predictions)
+# Run only after approval: construction may download the group archive.
+group = admet_group(path=".pytdc-benchmarks")
+benchmark = group.get("Caco2_Wang")
+train_val = benchmark["train_val"]
+test = benchmark["test"]
+train, valid = group.get_train_valid_split(
+    seed=1,
+    benchmark=benchmark["name"],
+    split_type="default",
+)
 ```
 
-**ADMET Group includes 22 datasets** covering absorption, distribution, metabolism, excretion, and toxicity.
+For one run, `group.evaluate({name: test_predictions})` returns metric results.
+For leaderboard aggregation, pass a **list of at least five prediction
+dictionaries** to `group.evaluate_many(...)`. Do not index `group.get(...)` by
+seed, and do not derive dummy predictions from test labels.
 
-### Other Benchmark Groups
+Use `scripts/benchmark_evaluation.py` to validate a bounded JSON prediction plan
+before any group download. See [references/utilities.md](references/utilities.md)
+for the exact JSON shape and API behavior.
 
-Available benchmark groups include collections for:
-- ADMET properties
-- Drug-target interactions
-- Drug combination prediction
-- And more specialized therapeutic tasks
+## Molecular generation and oracles
 
-For benchmark evaluation workflows, see `scripts/benchmark_evaluation.py`.
+PyTDC supplies molecule corpora, evaluators, and oracles; it does not train or
+provide a generic molecule generator in the core workflow. Discover current names:
 
-## Data Functions
-
-TDC provides comprehensive data processing utilities organized into four categories.
-
-### 1. Dataset Splits
-
-Retrieve train/validation/test partitions with various strategies:
-
-```python
-# Scaffold split (default for most tasks)
-split = data.get_split(method='scaffold', seed=1, frac=[0.7, 0.1, 0.2])
-
-# Random split
-split = data.get_split(method='random', seed=42, frac=[0.8, 0.1, 0.1])
-
-# Cold split (for DTI/DDI tasks)
-split = data.get_split(method='cold_drug', seed=1)  # Unseen drugs in test
-split = data.get_split(method='cold_target', seed=1)  # Unseen targets in test
+```bash
+uv run --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
+  python scripts/discover_metadata.py --kind oracles --limit 100
 ```
 
-**Available split strategies:**
-- `random`: Random shuffling
-- `scaffold`: Scaffold-based (for chemical diversity)
-- `cold_drug`, `cold_target`, `cold_drug_target`: For DTI tasks
-- `temporal`: Time-based splits for temporal datasets
+Plan bounded local QED scoring:
 
-### 2. Model Evaluation
-
-Use standardized metrics for evaluation:
-
-```python
-from tdc import Evaluator
-
-# For binary classification
-evaluator = Evaluator(name='ROC-AUC')
-score = evaluator(y_true, y_pred)
-
-# For regression
-evaluator = Evaluator(name='RMSE')
-score = evaluator(y_true, y_pred)
+```bash
+uv run --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
+  python scripts/molecular_generation.py score --oracle QED --smiles CCO
 ```
 
-**Available metrics:** ROC-AUC, PR-AUC, F1, Accuracy, RMSE, MAE, R2, Spearman, Pearson, and more.
+Add `--execute` only after review. LogP and SA call the downloadable `fpscores`
+artifact in 1.1.15; they and DRD2/GSK3B/JNK3/CYP3A4_Veith also require
+`--download`. The helper intentionally refuses remote services, docking,
+distribution, and composite oracles. It preserves input order and never assumes
+score direction.
 
-### 3. Data Processing
+Read [references/oracles.md](references/oracles.md) before any oracle call.
 
-TDC provides 11 key processing utilities:
+## Bundled resources
 
-```python
-from tdc.chem_utils import MolConvert
+### Scripts
 
-# Molecule format conversion
-converter = MolConvert(src='SMILES', dst='PyG')
-pyg_graph = converter('CC(C)Cc1ccc(cc1)C(C)C(O)=O')
-```

-- Molecule filters (PAINS, drug-likeness)
-- Label binarization and unit conversion
-- Data balancing (over/under-sampling)
-- Negative sampling for pair data
-- Graph transformation
-- Entity retrieval (CID to SMILES, UniProt to sequence)
+Every CLI uses lazy optional imports, safe relative output/cache paths, JSON

+Always cite the current version. The DOI and https://arxiv.org/abs/2609.00065 resolve to the
+latest arXiv version, so never append a version suffix such as `v1`. When network access is
+available, fetch https://arxiv.org/abs/2609.00065 (or
+http://export.arxiv.org/api/query?id_list=2609.00065) before writing the reference and take
+the author list, year, and version from that record. If the record lists a journal reference
+or publisher DOI, cite the published version instead.
