Second Opinion is a multi-agent healthcare AI tool that turns a patient's chart into a cited, fact-checked appointment brief designed for under-researched conditions starting with adenomyosis, a disease that takes 8 years on average to diagnose.                                                                                                                                               A patient drops in their full chart. Five Opus 4.7 agents run a structured consultation: three specialists fire in parallel (OB-GYN, Reproductive Endocrinology, Chronic Pain) consulting from a 32K-token corpus of 2026 guidelines, active clinical trials, and care pathways. A   
  synthesizer composes one cohesive brief. A verifier fact-checks every claim against the corpus and flags anything uncited — green badge = every claim sourced.                                                                                                                                  
The brief is research, not advice. Patient charts never persist on disk. The doctor's chair stays the doctor's chair. Output speaks 5 languages.
                                                                                                                                                  
Built solo in 5 days on Opus 4.7's 1M context window with prompt caching. Adenomyosis is the start; the same pipeline answers fibroids,
 endometriosis, Hashimoto's, long COVID, lupus, POTS — any condition that takes too long, gets dismissed too often, and has a literature too     
 dense for one appointment to hold. The corpus changes; the architecture doesn't.                                                           
                                                                                                                                                  
 Transparency: "Sandra" is an anonymized real patient profile (with consent). "Maya" and "Helena" are hand-authored composite cases. All five
  specialists are Opus 4.7 agents not human doctors. Care centers and citations are sourced from public medical literature.
