name: horizon_tc_ui — OpenExplorer toolchain CLI
description: >-
  Horizon Robotics' first-party command-line toolchain, shipped inside the OpenExplorer
  (OE) package. It is the primary developer interface to the Journey (征程) BPU platform:
  it takes a floating-point ONNX or Caffe model through YAML configuration, PTQ
  quantization, HBIR (.bc) and HBM (.hbm) artifact generation, then accuracy
  verification, performance analysis and on-board deployment. Horizon does not publish
  a hosted HTTP API for this — the CLI is the contract.
distribution:
  channel: OpenExplorer (OE) release package
  download: https://oe.horizon.auto/
  docs: https://doc.oe.horizon.auto/
  registry: none                # not published to PyPI/npm/conda — see packages/
  note: >-
    The OE package is a versioned tarball / Docker image obtained from the Horizon
    developer portal; a portal account is required for download. The CLI is not
    installable from any public package registry.

    - hb_model_info model.hbm
- name: verification
  commands:
  - name: hb_verifier

  - name: hb_eval_preprocess
    summary: Preprocess evaluation datasets for accuracy validation.
- name: performance
  commands:
  - name: hb_analyzer
    summary: Analyze model performance — latency, bandwidth, BPU utilisation, bottlenecks — from perf JSON or live board runs.
target_architectures:
- nash-b-lite
- nash-b
- nash-b-plus
- nash-e
- nash-m
- nash-p

key_flows:
- name: float model to on-board deployment
  steps: ONNX/Caffe model -> YAML config -> PTQ quantization -> HBIR (.bc) -> HBM (.hbm) -> accuracy verification / performance analysis / board deployment

  summary: >-
    An internal OE Skill Hub client referenced by the OE-Skills changelogs — `oe-cli skill
    inspect <skill> --version <semver>` reads per-version release notes from the Hub.

    Not documented publicly and not obtainable from any public location found; recorded
    because Horizon's own changelog files point readers at it, which means the public
    changelog is incomplete by design.

  note: >-
    Horizon packages this CLI for AI coding agents as the `horizon-tc-ui` and
    `hb-analyzer-performance` skills in OE-Skills — see skills/_index.yml.
