Performance Guardrails

Use this skill to make performance changes deterministic, measurable, and reviewable.

Scope

• Treat shaping, layout, rasterization, filtering, compositing, and frame-loop code as hot-path sensitive by default.
• Treat one-off tooling and debug-only paths as non-hot unless profiling shows impact.

Execution Workflow

1. Classify the path.

• Mark code as hot-path or non-hot-path.
• Default to hot-path for render pipeline work.
