## What it does

The skill runs an eight-phase workflow. It starts with compound disambiguation, turning a name into SMILES, a PubChem CID, and a ChEMBL ID. Then come predictive toxicology through ADMET-AI (AMES, DILI, LD50, hERG, carcinogenicity), ADMET properties, toxicogenomics from CTD, FDA label data, DrugBank safety, STITCH protein interactions, and ChEMBL structural alerts. The final step is an integrated risk assessment with data gaps called out.

Every toxicity claim carries an evidence grade from T1 to T4. Direct human evidence and regulatory findings sit at T1, animal and validated in vitro work at T2, model predictions and associations at T3, database annotations and text mining at T4. When a prediction conflicts with an experiment, the experiment wins.

The ADMET-AI phase needs the `tooluniverse[ml]` package, installed with `pip install tooluniverse[ml]`. Without it the skill skips predictive steps and falls back to CTD and PubChemTox. One more thing worth knowing: the skill refuses to guess. GHS categories, IARC classifications, and disease links get retrieved from tools rather than recalled by the model.

## When to use it
- check whether a chemical is toxic before handling it
- compare a model prediction against experimental findings
- find genes and diseases tied to a chemical exposure
- collect FDA label warnings and contraindications
- separate acute toxicity from chronic hazards

## Example prompts
- Assess the safety profile of this compound from its SMILES
- What genes does this chemical interact with, and what diseases are linked to it?
- Check the GHS classification and LD50 values for this CID

# Chemical Safety & Toxicology Assessment

**Toxicity assessment**: identify the chemical, check known hazards (GHS, IARC), then look for ADMET predictions. Dose makes the poison — always consider exposure level, as a compound that is toxic at high doses may be safe at relevant exposures. Distinguish between acute toxicity (LD50, GHS category) and chronic hazards (carcinogenicity, endocrine disruption) — they require different risk management approaches. Computational predictions (ADMETAI) are T3 evidence and must be anchored by experimental data from PubChemTox or FDA labels wherever available. When evidence conflicts between prediction and experiment, always defer to the experimental finding.

**LOOK UP DON'T GUESS**: never assume GHS categories, IARC classification, or CTD disease links — always call PubChemTox and CTD tools to retrieve current classifications before reporting.

Comprehensive chemical safety analysis integrating predictive AI models, curated toxicogenomics databases, regulatory safety data, and chemical-biological interaction networks.

## When to Use This Skill

**Triggers**:
- "Is this chemical toxic?" / "Assess the safety profile of [drug/chemical]"
- "What are the ADMET properties of [SMILES]?"
- "What genes does [chemical] interact with?" / "What diseases are linked to [chemical] exposure?"
- "Drug safety assessment" / "Environmental health risk" / "Chemical hazard profiling"

**Use Cases**:
1. **Predictive Toxicology**: AI-predicted endpoints (AMES, DILI, LD50, carcinogenicity, hERG) via SMILES
2. **ADMET Profiling**: Absorption, distribution, metabolism, excretion, toxicity
3. **Toxicogenomics**: Chemical-gene-disease mapping from CTD
4. **Regulatory Safety**: FDA label warnings, contraindications, adverse reactions
5. **Drug Safety**: DrugBank safety + FDA labels combined
