pubchem-pug-skill

Operating rules

• Use scripts/rest_request.py for all PubChem PUG calls.
• Use base_url=https://pubchem.ncbi.nlm.nih.gov/rest/pug.
• Property and description endpoints usually return a single focused record; assay or broader list endpoints are better with max_items=10.
• Re-run requests in long conversations instead of relying on older tool output.
• Treat displayed ... in tool previews as UI truncation, not literal request content.

Execution behavior

• Return concise markdown summaries from the script JSON by default.
• Prefer property, description, assay summary, and substance paths instead of broad record dumps.
• If the user needs the full payload, set save_raw=true and report the saved file path.
