Responsive audit

Run a requested viewport audit, not an automatic completion gate. Default to read-only. A review does not authorize edits, commits or publishing. Follow repository instructions if the user explicitly requests fixes.

Required context

Read context resolution and WORKFLOW.md. Select the first existing root, .agents/context/, then .github/contexts/. Read DESIGN-SYSTEM.md, PRODUCT-DESIGN.md, REPOSITORY.md, RESPONSIVE-DESIGN.md and BROWSER-VALIDATION.md directly there. No manifest or per-pack capability is required. Do not fall through for missing files or read drafts as active context.
