This skill pulls GHS Classifications, Hazard Classes, and Toxicological properties (like LD50/LC50 experimental animal records) for a given compound based on its CID, and performs GHS Acute Toxicity Category assignment and hazard statement consistency analysis.\n\n## Instructions\n\n### 1. Extract Safety Profile by CID\nProvide the precise CID of the molecule to query safety metadata.\n\n```bash\n# Env: base-agent\npython .agents/skills/chem-hazard-toxicity/scripts/get_safety_data.py \\\n  --cid 2519 \\\n  --outdir research/caffeine_safety \\\n  --output safety_caffeine.json\n```\n\n### 2. GHS Acute Oral Toxicity Triage Helper\nUse `--triage` to extract consensus GHS statements ($\\ge 50\\%$), lowest rat oral LD50, GHS acute oral category (1–5 or `unclassified`), and check oral hazard code consistency:\n\n```bash\n# Env: base-agent\npython .agents/skills/chem-hazard-toxicity/scripts/get_safety_data.py \\\n  --cid 2519 \\\n  --triage \\\n  --outdir research/caffeine_safety \\\n  --output triage_caffeine.json\n```\n\n### Python API Integration\nImport helper functions directly into python scripts:\n\n```python\nfrom scripts.get_safety_data import (\n    extract_consensus_ghs_codes,\n    extract_lowest_rat_oral_ld50,\n    assign_acute_oral_category,\n    check_oral_code_consistency,\n    profile_compound,\n)\n\nprofile = profile_compound(2519, threshold_percent=50.0)\n# Returns dict with cid, consensus_ghs_codes, oral_rat_ld50_mg_kg, oral_rat_ld50_evidence, acute_oral_category, ghs_oral_code_consistent\n```\n\n> **GHS Category & Code Consistency Rule**:\n> - Category 1 ($\\le 5\\text{ mg/kg}$) & Category 2 ($5 < \\text{LD}_{50} \\le 50\\text{ mg/kg}$) $\\rightarrow$ expected GHS oral code `H300` (*Fatal if swallowed*).\n> - Category 3 ($50 < \\text{LD}_{50} \\le 300\\text{ mg/kg}$) $\\rightarrow$ `H301` (*Toxic if swallowed*).\n> - Category 4 ($300 < \\text{LD}_{50} \\le 2000\\text{ mg/kg}$) $\\rightarrow$ `H302` (*Harmful if swallowed*).\n> - Category 5 ($2000 < \\text{LD}_{50} \\le 5000\\text{ mg/kg}$) $\\rightarrow$ `H303` (*May be harmful if swallowed*).\n> - `unclassified` ($> 5000\\text{ mg/kg}$) $\\rightarrow$ empty set (`{}`).\n\n## Constraints\n- **Data Availability**: Relies on experimental or reported data listed in PubChem.\n- **Network Limits**: Automatically handles standard `HTTP 503/429` rate limiting via exponential backoff.\n\n---\n---\n\n**Author:** Bowen Deng\n**Contact:** [GitHub @learningmatter-mit](https://github.com/learningmatter-mit)\n","tagline":"Extract explicit safety warnings, GHS classifications, LD50 toxicity profiles, and acute oral toxicity triage from PubChem PUG VIEW.","category":"[chemistry, drug-discovery]","tags":["agent-skill"],"author":"learningmatter-mit","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"learningmatter-mit/AtomisticSkills","creatorName":"learningmatter-mit","creatorUrl":"https://github.com/learningmatter-mit","sourceUrl":"https://github.com/learningmatter-mit/AtomisticSkills/tree/main/.agents/skills/chem-hazard-toxicity","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/learningmatter-mit-chem-hazard-toxicity#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
