Holoscan Sensor Bridge demo bring-up

Holoscan Sensor Bridge demo bring-up

Use this skill when the user wants to bring up the Holoscan Sensor Bridge demo environment end to end.

This workflow has side effects. Never run it automatically. Only run it when the user explicitly invokes it.

Before you start — required gates (do these first, in order)

Gate 1 — Read environment variables. Before doing anything else, check these variables and print their resolved values to the user:

SSH_TARGET      Remote devkit login (e.g. [email protected]). Ask the user if not set.
REMOTE_ROOT     Remote working directory (e.g. /home/nvidia). Ask the user if not set.
REMOTE_SUDO     sudo / sudo -n / "" — default to "sudo" if not set.
REMOTE_SSH_OPTS Additional SSH options (optional).
HSB_PLATFORM    Platform hint — may be empty; will detect from hardware.
HSB_REPO        Custom repo URL — defaults to https://github.com/nvidia-holoscan/holoscan-sensor-bridge.git

SSH_TARGET and REMOTE_ROOT are required. Stop and ask the user for them if either is missing.

Gate 2 — Present the phase plan. Before taking any action, show the user this exact plan and wait for acknowledgement:

HSB Setup — Phase Plan
  Phase 0: Token-budget preflight
  Phase 1: Confirm platform, set up SSH, clone repo, study user guide
  Phase 2: Host prerequisite checks and network setup
  Phase 3: Native CLI build (AGX Thor only — skipped for other platforms)
  Phase 4: Build demo container, run it, ping 192.168.0.2, verify FPGA version
  Phase 5: Issues report (with option to save)
  Phase 6: Stop apps, exit container, hand control back to user

Gate 3 — Token-budget preflight (Phase 0). Run this before any SSH connection or devkit change. See ## Token-budget preflight section for the full procedure. Do not proceed to Phase 1 until the budget check passes.

Instructions

Invoke this skill by typing /hsb-setup [PLATFORM] [OPTIONS]. The skill walks through each phase interactively, prompting for confirmation before making changes.
