Execute Epic MyChart SMART on FHIR patient-record operations using the `mychart` CLI. The `mychart` CLI follows this pattern: ```bash mychart [arguments] [options] ```

Task	Command
Check auth	mychart auth status
Login	mychart auth login
Inspect FHIR metadata	mychart metadata get --properties resourceType,fhirVersion
List supported FHIR types	mychart types list --table
Get patient context	mychart patient get --table
List observations	mychart resources list Observation --limit 10
Get clinical summary	mychart summary get --resource Observation --resource MedicationRequest
</quick_start>

**MANDATORY: Consult the adjacent `usage.json` at `/_repo/skills/-cli/usage.json` before executing ANY `mychart` command.** This file contains complete command syntax, arguments, options, and usage instructions for every command. Never guess at command syntax. `mychart` uses Epic SMART on FHIR OAuth with PKCE. A patient-facing Epic on FHIR Client ID and registered loopback redirect URI are required for patient data. Metadata, OAuth discovery, and supported type discovery can run without authentication. - **auth** -- Authentication and profile management. - **metadata** -- FHIR CapabilityStatement metadata. - **oauth** -- SMART OAuth endpoint discovery. - **types** -- Supported FHIR resource types. - **resources** -- Generic FHIR resource list/get/search. - **patient** -- Patient resource access. - **summary** -- Grouped read-only clinical summaries. - **cache** -- Response cache management. </essential_principles> **`usage.json`** -- Complete command tree with arguments, options, defaults, and usage instructions for every command. </reference_index> - Command executes without error. - Output is displayed in requested format. - Correct command and flags used, verified against `usage.json`. </success_criteria>
