I4h Workflow Setup Agent Skill

i4h Workflow — Setup

Purpose

Verify host requirements and run the idempotent workflows/agentic/setup.sh to bootstrap the agentic workflow. Use when asked to set up, install, or bootstrap the workflow, or when hitting a missing .venv, third-party checkout, or engine error.

Base Code

These steps drive the i4h-workflows base code (the workflows/agentic/ tree). To reuse an existing checkout, set I4H_WORKFLOWS to its path (no clone happens). Otherwise this resolves the current repo, or clones to ~/i4h-workflows — pick that default without prompting. Run every command below from the resolved root:

# Resolve the i4h-workflows base code (provides workflows/agentic/).
ROOT="${I4H_WORKFLOWS:-$(git rev-parse --show-toplevel 2>/dev/null)}"
if [ ! -d "$ROOT/workflows/agentic" ]; then
  ROOT="${I4H_WORKFLOWS:-$HOME/i4h-workflows}"
  [ -d "$ROOT/workflows/agentic" ] || git clone https://github.com/isaac-for-healthcare/i4h-workflows "$ROOT"
fi
export I4H_WORKFLOWS="$ROOT"; cd "$ROOT"

Basics

• workflows/agentic/setup.sh is the idempotent setup entry point.
• Cosmos setup is separate; invoke only when the user asks for Cosmos or video transfer.

Preflight

command -v uv
command -v git
nvidia-smi
df -h .

Required: Linux, uv, git, NVIDIA driver/GPU, disk space for third-party checkouts. Docker is optional unless using Cosmos or local VLM containers.

Run the steps below in order. Each step is a separate bash call; variables persist in the local agent's tmux session.

Step 1 — resolve repo and run dir

REPO_ROOT="${I4H_WORKFLOWS:-$(git rev-parse --show-toplevel 2>/dev/null)}"; [ -d "$REPO_ROOT/workflows/agentic" ] || REPO_ROOT="$HOME/i4h-workflows"
RUN_DIR="${REPO_ROOT}/workflows/agentic/runs/setup_$(date +%Y%m%d_%H%M%S)"
mkdir -p "${RUN_DIR}/logs"
ln -sfn "${RUN_DIR}" "${REPO_ROOT}/workflows/agentic/runs/.latest"

Step 2 — run setup

On a freshly cloned repo the harness may ask to approve setup.sh once. Set I4H_WORKFLOWS to a pre-existing trusted clone to skip the fresh-clone gate.

"${REPO_ROOT}/workflows/agentic/setup.sh" > "${RUN_DIR}/logs/setup.log" 2>&1

Watch progress with tail -f "${RUN_DIR}/logs/setup.log". For component-specific retries (also idempotent):

"${REPO_ROOT}/workflows/agentic/third_party/setup.sh"
"${REPO_ROOT}/workflows/agentic/policy/gr00t_n16/setup.sh"

Verify

"${REPO_ROOT}/workflows/agentic/policy/run.sh" --list-envs
"${REPO_ROOT}/workflows/agentic/arena/run.sh" --list-envs
"${REPO_ROOT}/workflows/agentic/policy/run.sh" --env scissor_pick_and_place --dry-run
"${REPO_ROOT}/workflows/agentic/arena/run.sh" --env scissor_pick_and_place --dry-run

Prerequisites

• Linux host with uv, git, and an NVIDIA driver/GPU (check via the Preflight commands).
• Disk space for the third-party checkouts (df -h .).
• Docker only when using Cosmos or local VLM containers; otherwise optional.

Limitations

• Linux only; requires an NVIDIA driver/GPU.
• Cosmos setup is separate — setup.sh does not run it; invoke Cosmos only when the user asks for it.
• Verify steps use --list-envs and --dry-run; they confirm envs register and build, not that a full rollout works.

Troubleshooting

• Error: uv / git / nvidia-smi not found — Cause: missing host requirement. Fix: install it and re-run Preflight before setup.sh.
• Error: a single component fails partway through setup — Cause: a checkout or component venv did not finish. Fix: re-run that component's script (e.g. third_party/setup.sh, arena/setup.sh, policy/setup.sh); all are idempotent.
• Error: --list-envs or --dry-run fails after setup — Cause: setup incomplete or a component venv missing. Fix: inspect ${RUN_DIR}/logs/setup.log (or workflows/agentic/runs/.latest/logs/setup.log) and re-run setup.sh or the failing component script.
• Error: setup.sh fails instantly redirecting to a missing log dir — Cause: Step 2 ran before Step 1, so ${RUN_DIR}/logs does not exist. Fix: run Step 1 first, then Step 2.

Final Response

Report setup status, failed component (if any), relevant log path, next recommended smoke test.
