OpenAPI formats not supported?

OpenAPI formats not supported?: a task in MiMo-V2.6-RL-harbor-code: MiMo-V2.6-RL Code (Harbor) (Harbor dataset). However, I cannot find these in the OpenAPI 3.0 schema itself at github (https://github.com/OAI/OpenAPI-Specification/blob/master/schemas/v3.0/schema.yaml).
