i4h Agentic Workflow
Purpose
Orient on the agentic workflow before touching a specific stage: which envs/robots/policies are supported, how the workflows/agentic/ subprojects fit together, and which per-stage skill to invoke next. This skill routes — it runs no pipeline stage itself.
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 "$ROOT"
Basics
- Env YAMLs at
workflows/agentic/config/environments/<env>.yamlare the source of truth. - Each pipeline stage has its own skill. Compose them or use [[i4h-workflow-e2e]] for full runs.
- For env authoring or scene-edit source changes, load
skills/i4h-workflow/references/repo-map.mdbefore generating code.
Supported Envs
Fallback when --list-envs fails (setup incomplete):
| Env | Robot | Policy |
|---|---|---|
scissor_pick_and_place | SO-ARM 101 | GR00T N1.5 (N1.7 alternative) |
locomanip_tray_pick_and_place | Unitree G1 | GR00T N1.6 (shared policy.locomanip.*) |
locomanip_push_cart | Unitree G1 | GR00T N1.6 (shared policy.locomanip.*) |
assemble_trocar | Unitree G1 + Dex hands | GR00T N1.5 (inference-only) |
ultrasound_liver_scan | Franka-style arm | openpi PI0 |
surgical_reach_psm | dVRK PSM | GR00T N1.5 or scripted state machine |
surgical_reach_dual_psm | dVRK dual PSM | GR00T N1.5 or scripted state machine |
surgical_reach_star | STAR | GR00T N1.5 or scripted state machine |
surgical_lift_block | dVRK PSM | GR00T N1.5 or scripted state machine |
surgical_lift_needle | dVRK PSM | GR00T N1.5 or scripted state machine |
surgical_lift_needle_organs | dVRK PSM | GR00T N1.5 or scripted state machine |
Run
Run the step below before answering. Each step is a separate bash call; variables persist in the local agent's tmux session.
Step 1 — list supported envs
REPO_ROOT="${I4H_WORKFLOWS:-$(git rev-parse --show-toplevel 2>/dev/null)}"; [ -d "$REPO_ROOT/workflows/agentic" ] || REPO_ROOT="$HOME/i4h-workflows"
"${REPO_ROOT}/workflows/agentic/policy/run.sh" --list-envs
If the command fails, use the Supported Envs fallback table above.
Subprojects
| Directory | Purpose |
|---|---|
workflows/agentic/arena/ | IsaacLab-Arena envs, scenes, tasks, teleop, record, replay |
workflows/agentic/policy/ | Policy daemons and train dispatchers |
workflows/agentic/dataset/ | HDF5 → LeRobot conversion and visualization |
workflows/agentic/mimic/ | HDF5 trajectory expansion |
workflows/agentic/annotator/ | VLM success labels and filtering |
workflows/agentic/cosmos/ | Optional Cosmos Transfer video augmentation |
workflows/agentic/common/ | Shared config, messaging, robot constants |
Skill Index
| Skill | Purpose |
|---|---|
i4h-workflow-setup | Install / sync / check third-party deps |
i4h-workflow-create | Add a new env |
i4h-workflow-scene-edit | Edit an existing scene / task / camera |
i4h-workflow-dataset-teleop | Record human demos |
i4h-workflow-dataset-replay | Replay HDF5 episodes |
i4h-workflow-dataset-mimic | Expand HDF5 demos with noise |
i4h-workflow-dataset-annotate | VLM label / filter episodes |
i4h-workflow-dataset-convert | Convert HDF5 to LeRobot |
i4h-workflow-finetune | Train supported envs |
i4h-workflow-validate | Roll out / evaluate policy checkpoints |
i4h-workflow-e2e | Run the full pipeline |
i4h-lerobot-viz | Open the LeRobot HTML viewer |
Prerequisites
- For any hands-on stage, set up the workflow first — see [[i4h-workflow-setup]] (component venvs and third-party checkouts present).
- Env YAMLs at
workflows/agentic/config/environments/<env>.yamlare the source of truth.
Limitations
- Overview/routing only — each pipeline stage has its own skill; this one performs no recording, training, or rollout.
Troubleshooting
- Error: env not found / unsupported — Cause: typo, unregistered env, or setup incomplete. Fix: run
workflows/agentic/policy/run.sh --list-envs; if that fails, run [[i4h-workflow-setup]] first; otherwise check the Supported Envs table.
Final Response
The response is incomplete unless it includes all three parts below, each separated by a blank line. Do not reply with prose only or run sections together without spacing.
-
Orientation — one short paragraph: env YAMLs, subprojects, sim-to-policy pipeline.
-
Supported envs — heading plus markdown table from Step 1 (
--list-envsoutput: env, stack, description) or the Supported Envs fallback table. -
Available skills — heading plus the full Skill Index table copied into the response.
Then (after another blank line) recommend [[i4h-workflow-setup]] if setup is not done, and name one next stage skill matched to the user's goal.
