Use when deciding whether a Lightning Web Component should keep the default Shadow DOM or opt into Light DOM via `static renderMode = 'light'`. Covers CSS scoping, third-party CSS-framework compatibility, accessibility implications, Experience Cloud LWR vs internal-app constraints, performance differences, and event composition. NOT a generic Light DOM how-to (see lwc/lwc-light-dom). NOT a CSS styling reference (see lwc/lwc-styling-and-slds). NOT for managed-package distribution rules — that is a hard constraint and Light DOM is forbidden there.

From the source SKILL.md

Activate this skill when a developer is choosing the render mode for an LWC and the decision is non-trivial — a corporate CSS theme has to reach inside, an Experience Cloud LWR site needs SEO and screen-reader visibility, an Aura host page is bleeding styles in, or a security-sensitive form needs the strongest possible encapsulation. The output is a single recommendation (Shadow DOM default OR Light DOM opt-in), the CSS / event / accessibility strategy that goes with it, and a checker that flags the most common drift between intent and implementation.
