# Clinical Trial Matching - Tools Reference

## Summary

This skill uses **40+ ToolUniverse tools** across 10 categories to perform comprehensive clinical trial matching.

## Critical Parameter Notes

1. **DrugBank tools**: ALL 4 parameters (`query`, `case_sensitive`, `exact_match`, `limit`) are REQUIRED
2. **`search_clinical_trials`**: `query_term` is REQUIRED even for disease-only searches
3. **`ClinicalTrials_search_studies`**: `action` must be exactly `"search_studies"`
4. **`ClinicalTrials_get_study`**: `action` must be exactly `"get_study_details"`
5. **CIViC `civic_search_variants`**: Does NOT filter by query - returns alphabetically
6. **CIViC `civic_get_variants_by_gene`**: Takes CIViC gene ID (integer), NOT gene symbol
7. **OpenTargets drug lookup**: Use `drugName` (NOT `genericName`)
8. **Batch clinical trial tools**: Accept arrays of NCT IDs
9. **`fda_pharmacogenomic_biomarkers`**: Takes no parameters
