Use for compatibility repair of deprecated FET_004_ROBOT_PHYSX SimReady conformance. Use only when a historical or external profile, validation report, asset stamp, or user request explicitly names FET_004_ROBOT_PHYSX; never select it for a new profile version.

The file

We split this skill into the rules it gives an agent

7 rules. About 0 are common, 5 are distinctive, and 2 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈5

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

SimReady Conform FET_004_ROBOT_PHYSX

Purpose

Use this exact feature skill when the selected profile, validation report, or user request names FET_004_ROBOT_PHYSX. It repairs or stages simulate multi-body physics (robot physx) conformance without drifting into another runtime contract.

FET_004_ROBOT_PHYSX is deprecated. This skill exists only to preserve compatibility with historical or external contracts and assets that explicitly name the feature. Never select or recommend it for a new profile version; use FET_003_PHYSX@0.4.0 and FET_004_PHYSX@0.4.0 instead.

Default to FET_004_ROBOT_PHYSX@0.4.0 when the user asks for this feature without a version. Use an older integer version only when the profile, validation report, or user explicitly pins it. If the report names a different FET_###_RUNTIME feature, switch to that feature's matching skill before editing.

Feature Adapter

When the input already conforms to the neutral base feature, prefer the deterministic feature adapter to author the runtime-specific data first (via the workspace upgrade command; see nv_core/sr_specs/docs/guides/feature_adapters/feature_adapters.md), then repair only the residual requirements below.

Adapter moduleAdapterTransitionAuthors
nv_core/cip_specs/asset_handler_modules/neutral_to_physxrigid_body_neutral_to_robot_physxFET_003_STANDARD@0.1.0 -> FET_004_ROBOT_PHYSX@0.2.0Mesh extents on all meshes.
  • The adapter runs on a staged output stage and never creates geometry, joints, or articulation topology; it only annotates existing prims.
  • It only authors mesh extents (targeting @2). The robot RB.*, JT.*, RB.MB.001, and PHYSX.COL.* requirements — and the @4 default — must be repaired manually per the Workflow below on existing robot link/joint topology.

Workflow

  1. Confirm the input exists and identify the exact selected feature/version from the profile TOML, validation report, or user request.
  2. Load the selected FET_004_ROBOT_PHYSX manifest and the feature markdown before editing.
  3. Load requirement docs linked from the feature markdown for every reported failing requirement.
  4. Create or use a staged output location unless the user explicitly asks for in-place edits.
  5. Repair only the requirements listed by the selected FET_004_ROBOT_PHYSX manifest and its dependencies.
  6. Rerun the same profile gate or the narrowest available feature/capability validation gate. If runtime evidence is required and unavailable, report that limitation instead of claiming a pass.
  7. Summarize the selected FET_004_ROBOT_PHYSX version, changed files, validation evidence, and the first remaining blocker or next exact feature gate.

Feature Guidance

  • Use this legacy robot PhysX feature only when the profile pins it or needs its robot-specific collider exemption.
  • Preserve robot link and joint semantics; leave robot identity to FET_021_* and driven actuation to FET_022_*.
  • Do not create new geometry to satisfy this feature.
