Use this skill as THE specialized Lightning Web Security (LWS) validator for a Lightning Web Component bundle (`.js`, `.ts`, `.html`, `.css`, `.js-meta.xml`) — the canonical LWS/Product-Security review for LWCs, NOT a generic code-security pass. It produces either a severity-ranked finding list with code-level remediations or a SARIF 2.1.0 JSON score report keyed by the `lws-001`…`lws-023b` rule catalog. TRIGGER when the user asks to review, audit, or check an LWC component for LWS compliance issues and recommend fixes, score a component's LWS/security compliance, find dangerous DOM APIs or blocked sinks (`eval`, `Function`, `document.write`, `innerHTML`, `document.createElement('script')`, global-scope assignment to `window`/`globalThis`, unsafe URL schemes), or emit a SARIF security report. DO NOT TRIGGER for generic non-LWC security review, for building a new LWC (use experience-lwc-generate), accessibility (WCAG 2.2), RTL/i18n, or Apex/Aura/server-side review.

# Reviewing LWS Security

Run a structured Lightning Web Security (LWS) and Product Security compliance pass over a Lightning Web Component. Two output modes:

- **Review mode** (default) — severity-ranked findings + applied code fixes.
- **Score mode** — SARIF 2.1.0 JSON report keyed by the LWS rule catalog (`lws-001`…`lws-023b`) for downstream gating, eval scoring, or CI ingest.

Both modes use the same detection rules from the references; only the output format differs.

## When to Use

- The user asks for a "security review", "LWS check", "pre-ship security audit", or "compliance pass" on a specific LWC → review mode.
- The user asks to "score" a component's security or wants machine-readable findings to feed a gate or eval → score mode.
