	Description		Read-only	Idempotent	Open world
`fetch_source_record`Read the indexed text of one public-source record by its recordId (returned by search_medical). Use after search when the excerpt is not enough. Returns a bounded text window; pass nextInput unchanged to continue. contentCapped reports text unavailable beyond the stored content.

`search_medical`Hybrid keyword + semantic search over Arca's mirrored public-source corpus: FDA drug labels, Drugs@FDA approvals, complete response letters, warning letters, Orange Book, Purple Book, NDC, drug shortages, device 510(k)/PMA/registrations, MAUDE adverse events, food/supplement/cosmetic and animal drug adverse events, tobacco product problem reports, DailyMed, GUDID, postmarket requirements, import refusals, inspections, Form 483s, ClinicalTrials.gov studies, VAERS reports, CDC data, EU expert panel opinions, and BfArM/PMDA device vigilance. Press releases, SEC company filings and patents are searched only when sourceTypes names press_releases, company_filings or patents. Read-only lookup of already-published records: it cannot file, submit, or report anything to FDA, VAERS, MedWatch, or any other agency, so do not call it for requests to file or submit a report. When the question names a record type (warning letters, labels, adverse event reports, trials, recalls), pass the matching sourceTypes rather than searching the whole corpus. Results carry recordId for fetch_source_record and a citable source URL.
