lint: Run lint to compare your latest spec version to your team’s standards.
diff: `optic diff` prints the changes in your current spec against the previous version in version control, and checks the changes for compliance with your team’s standards.
capture: With `optic capture` developers can test an API, record the traffic, and update OpenAPI specs automatically from the result
bundle: `optic bundle` generates a single file from a multi-file OpenAPI spec to help your team distribute it more easily.
