# nemo_gym.data.tasks.harbor

Read Harbor task folders and hub references into NeMo Gym materialized tasks.

Harbor is the input format; Gym owns execution. A task is a folder holding
`task.toml`, `instruction.md`, `environment/` and `tests/`. A dataset is a
folder of task folders. `harbor:<dataset>[@<version>]` names a dataset in the
Harbor registry, which this package fetches into `environments/harbor/` in the Gym checkout, or
under the working directory when Gym is installed as a package (`gym dataset pull`;
`nemo_gym.data.tasks.harbor.hub.datasets_dir`); a committed entry there declares its dataset as
`[gym] source` and is pulled into its own folder (`nemo_gym.data.tasks.harbor.entries`).

This package is the Harbor format's public API.
Code outside `nemo_gym/` imports Harbor names from `nemo_gym.data.tasks.harbor`, not from `nemo_gym.data`.
