SKILL.md

This skill helps you verify that your implemented model correctly respects its intended symmetries. Even with equivariant libraries, implementation bugs can break equivariance. This skill provides systematic verification tests and debugging strategies.

Why audit? A model that claims equivariance but isn't will train poorly and give inconsistent predictions. Catching these bugs early saves debugging time.

Collect: the implemented model, the intended symmetry group, whether each output should be invariant or equivariant, the transformation functions for input and output spaces. Review the architecture specification from design phase. Clarify ambiguities with user before testing.

Use when you have implemented an equivariant model and need to verify it correctly respects the intended symmetries. Invoke when user mentions testing model equivariance, debugging symmetry bugs, verifying implementation correctness, checking if model is actually equivariant, or diagnosing why equivariant model isn't working. Provides verification tests and debugging guidance. Source: lyndonkl/claude.
