An example agentic engineering session. A Claude Code lead agent writes a sync of oncology visits, diagnoses and imaging studies from Epic's FHIR R4 API, then hands the tests to a shell and the review to an OpenCode agent running GLM-5.3. The tests and the reviewer both catch a patient MRN written to the logs. The lead logs the FHIR resource id instead, the tests pass and the reviewer approves.
