Tasks and Presets

Use this sub-skill when the task is about Isaac Lab environment IDs, preset selectors, task config loading, or environment discovery.

Route here for

• Listing available Isaac task IDs and their Gymnasium entry points.
• Understanding physics=, renderer=, and presets= selectors.
• Parsing task configs from the Gym registry.
• Reasoning about PresetCfg, PresetTarget, and Hydra preset resolution.
• Debugging preset-related parser or resolver errors.
• Checking that task config loading stays Kit-free before the simulator launches.

Use other subskills for

• RL train/play wrappers and checkpoint playback: ../rl-training/SKILL.md.
• Launching the simulation app itself: ../simulation-core/SKILL.md.
• Asset and sensor catalog choices used inside a task config: ../assets-and-sensors/SKILL.md.

Working references

• references/preset-system.md explains the typed selector grammar and resolver behavior.
• references/task-catalog.md explains environment listing, config loading, and safe discovery checks.
• references/troubleshooting.md covers preset and config-loading failure modes.
• scripts/list_task_presets.py lists task IDs and optionally prints preset groups from an installed Isaac Lab environment.

Acceptance checks

• Explain the selector grammar for the requested task.
• Identify the correct task or preset names for the requested environment.
• Preserve typed selector tokens verbatim until Hydra registration resolves them.
• Use the bundled helper to confirm the task registry or preset groups when needed.
