The body is mostly efficient API reference with no basic-concept padding, but at ~600 lines it includes redundant material — notably the "Complete Example: Physics Playground" duplicates the individual workflow examples — so it could be tightened.

Provides fully executable, copy-paste-ready TypeScript snippets with concrete property tables and enum values, matching the level-3 anchor for executable code and specific examples.

Workflows like "Creating a Dynamic Physics Object" are clearly numbered (1–4) and sequenced; physics setup is not a destructive/batch operation requiring validation checkpoints, and the Troubleshooting section supplies error-recovery guidance.

Sections are well-organized, but the skill is a monolithic ~600-line SKILL.md with no bundle files and no references split out — content such as the material tuning guide, troubleshooting, and complete example are inline when they could be separate files.

Lists multiple concrete actions — "adding physics simulation, configuring rigid bodies, collision shapes, applying forces, creating grabbable physics objects, or troubleshooting physics behavior" — matching the level-3 anchor of multiple specific concrete actions.

Explicitly states what ("Guide for implementing physics in IWSDK projects") and when ("Use when adding physics simulation...") with an explicit trigger clause, satisfying the level-3 anchor for both what and when.

Covers natural terms a user would say ("physics simulation", "rigid bodies", "collision shapes", "applying forces", "grabbable physics objects", "troubleshooting physics") with good variation, matching the level-3 anchor.

Scoped specifically to IWSDK physics with distinct triggers, making it unlikely to fire for unrelated skills; matches the level-3 clear-niche anchor.
