Capability Map

  • Repository files

    Public models and datasets, selection, revision and output.

    Run examples

  • Preflight and resume

    Explicit selection, commit pinning and destination identity; size-based completion checks.

    Read constraints

  • Reusable interfaces

    CLI adapters call importable Python functions; aria2 transfers files.

    Interface mapping

Implemented

Capability Interface Boundary
Models and datasets download, --repo-type Public repository files, not training or inference
Compatible mirrors --endpoint, HF_ENDPOINT HF-Mirror by default; no cross-platform fallback
Download root CHATHFD_DOWNLOAD_ROOT, ChatEnv, --local-dir Cwd default + repo ID; explicit local-dir is final; no automatic shared-path configuration
Concurrency and resume --connections, --jobs Local aria2 and matching destination identity
Selection and size preview --include, --exclude, --dry-run Metadata preflight, not a hard byte quota
Engine preparation setup [--install] Explicit, confirmed system package installation
Python calls download_repo, fetch_metadata, setup_aria2 Still use Click output/errors; see API reference

Outside the current boundary

  • Login, token management or forwarding for private/gated Hub repositories.
  • Native ModelScope downloads, wget backend or automatic replacement of old hfd aliases.
  • Standard Hugging Face cache migration or automatic legacy adoption, remote mounts, job queues or background daemons.
  • Upstream cryptographic verification, inference validation or dataset training pipelines.

A successful config or README download is not a completed weight download. Quickstart distinguishes small examples from full repositories.
