DDInter Query Skill

SkillDatabases & data

Query the DDInter drug-drug interaction database. Use whenever the user asks about drug-drug interactions, DDI severity levels, or wants to look up interactions for a drug name or DDInter ID.

Instructions available. Your AI can read the instructions. Execution depends on the setup they require.

Account requirements not reviewed. Check the skill instructions before use; ahel provides instructions and does not run this skill.

Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.

Then ask your AI: use the DDInter Query Skill skill

`summarize(hits, entity)`	hit list + label	compact text
`to_json(hits)`	hit list	`list[dict]`
`list_drugs()`	—	sorted unique drug names
