name: clinical-evidence-search description: "Use OpenEvidence for clinical questions: queries, citations, drug interactions, and guideline lookups. Always cite sources and flag the educational-only caveat."

Clinical evidence search

• Use open_evidence_search for clinical / drug / guideline questions. Set evidenceLevel to meta-analysis or rct when the user wants the strongest signal; use any only for broad scoping.
• Use open_evidence_get_citation to resolve any citation id before quoting a specific claim — never paraphrase a study you have not opened.
• Use open_evidence_drug_interactions for medication interaction checks (≥ 2 drugs). Report each pair with severity and the OpenEvidence citation behind it; do not collapse the list into a one-line yes/no.
• Use open_evidence_guideline_lookup to find society guidelines (ACC/AHA, ESC, NICE, USPSTF, …); pass the issuing body in society when the user asked for one specifically.
• OpenEvidence is US-only and not available in the EU/UK. If the user's locale is European, fall back to academic_search (PubMed) and label the limitation explicitly.
• Educational use only. Every reply that includes clinical content must end with: Not medical advice; verify against your local guidelines and a qualified clinician. Surface citations inline (journal, year, evidence level, DOI / PubMed id).
• For non-clinical research (math, CS, etc.) prefer academic_search — it is free, broader, and not subject to OpenEvidence's TOS.
