i4h Workflow Setup

Name: i4h-workflow-setup
Author: nvidia

Purpose

Prepare the complete runtime, then prove dependency-light workflow discovery works.

Instructions

Resolve the base checkout.
Run every host preflight check.
Run default full setup.
Verify discovery and lint --all.

Resolve the checkout

export I4H_WORKFLOWS_REPO_URL="${I4H_WORKFLOWS_REPO_URL:-https://github.com/isaac-for-healthcare/i4h-workflows}"
I4H_REPO_DIR_NAME="${I4H_WORKFLOWS_REPO_URL%/}"
I4H_REPO_DIR_NAME="${I4H_REPO_DIR_NAME##*/}"
I4H_REPO_DIR_NAME="${I4H_REPO_DIR_NAME##*:}"
I4H_REPO_DIR_NAME="${I4H_REPO_DIR_NAME%.git}"
[ -n "$I4H_REPO_DIR_NAME" ] || { echo "Cannot derive a checkout name from I4H_WORKFLOWS_REPO_URL" >&2; exit 2; }
ROOT="${I4H_WORKFLOWS:-$(git rev-parse --show-toplevel 2>/dev/null)}"
if [ ! -d "$ROOT/workflows/i4h_workflows" ]; then
  ROOT="${I4H_WORKFLOWS:-$HOME/$I4H_REPO_DIR_NAME}"
  [ -d "$ROOT/workflows/i4h_workflows" ] || git clone "$I4H_WORKFLOWS_REPO_URL" "$ROOT"
fi
export I4H_WORKFLOWS="$ROOT"
cd "$ROOT"

Treat this resolver as part of the skill contract: a hosted copy may run outside the base repository, so never assume the current checkout contains workflows/i4h_workflows. I4H_WORKFLOWS_REPO_URL selects the clone source. When I4H_WORKFLOWS is unset, derive the fallback directory from that URL; set I4H_WORKFLOWS only to reuse or choose a specific destination. Never replace an existing checkout.

Preflight

uname -srm
command -v uv
command -v git
nvidia-smi
df -h .
./setup.sh --help

Require supported Linux on x86_64 or aarch64, uv, Git, network access for missing packages/assets, sufficient disk and model-cache space, and an NVIDIA driver compatible with the repository's Isaac Sim version. Read the exact current requirements from ./README.md; do not rely on remembered version numbers. Require Docker only when the requested local VLM or Cosmos service needs it.

Sync

Run the default full setup:

./setup.sh

The explicit equivalent is:

./setup.sh all

Use ./setup.sh clean only when the user explicitly requests a full rebuild or cleanup because it deletes generated caches, component environments, and third-party checkouts. Setup is idempotent; do not clean as a generic repair. The setup script restores pinned third-party sources and the upstream Isaac Sim skill catalog; do not copy that catalog into skills/.

Verify

./run.sh list
./run.sh lint --all
test -f ./third_party/IsaacSim-045ca8b/skills/SKILLS.md

Use run.sh show <workflow> --mode <mode> when the user named a workflow. These checks prove discovery and contracts without importing Isaac Sim. Use i4h-workflow-validate for an actual rollout.

Troubleshooting

On failure, report the first host, network, checkout, or uv-sync error and rerun full setup only after correcting that cause.

Prerequisites

Require supported Linux, network access, uv, Git, disk space, and a compatible NVIDIA GPU/driver for simulator use.

Limitations

Setup does not download every optional checkpoint or prove any rollout succeeds. clean is destructive to generated environments and third-party checkouts.

Examples

Set up the i4h workflow on this machine and tell me if any host requirements are missing. → preflight, run default full setup, then run discovery and lint --all.

Completion gate

Report every host check, synced target, first failing component if any, discovery/lint results, and the smallest next smoke command. Do not claim simulator or policy success from setup alone.

Use it

Copy one of these into your project. Installing also returns the manifest and these snippets.

yaml

targets:
  - https://api.opensmartroute.ai/api/v1/registry/nvidia-skills-i4h-workflow-setup/manifest   # or paste the manifest below

Manifest

An Open Capability Manifest: the router reads it to know what this does, what it costs and when to pick it.
