Use this whenever a PR has a Vercel preview URL and needs browser QA against acceptance criteria — happy path, errors, empty states, responsive behavior, a11y basics — even if the user just says "check the preview". Requires a preview URL. NOT for release/deploy-readiness checks (no preview needed there) — use deploy-ready.
Plan and split work into parallel worktree sessions. Use whenever the user wants to work on multiple tasks at once, mentions parallel sessions, worktrees, "split this up", "dispatch", or lists several independent tasks for one work session.
Use this skill when implementing or reviewing UI that needs semantic HTML, keyboard navigation, focus management, ARIA labels, color contrast, reduced motion, forms, modals, or public-facing pages. Do not use as a standalone product-planning or backend workflow; pair it with design-system-ui, responsive-ui, or vercel-preview-qa when broader UI review is needed.
Use this skill when working across client, agency, consulting, or personal projects where code, data, credentials, prompts, or reusable patterns could leak between contexts. Do not use for ordinary single-project work with no cross-client or cross-workspace boundary risk.
Use this skill when creating components, implementing Figma designs, cleaning inconsistent styling, adding or reviewing tokens, spacing, typography, or component variants. Do not use for backend work, feature scoping, or visual QA that requires a live preview instead of design-system decisions.
Use this skill when importing ChatGPT or Claude exports, old Notion databases, local notes, or messy knowledge dumps into a durable knowledge system after redaction, deduplication, and classification. Do not use for live project planning, raw unredacted client data, or content that should remain out of Notion.
Use this skill when repeated corrections, a significant feature, a slow debugging session, or a weekly review create evidence for reusable patterns and skill or CLAUDE.md updates. Do not use for one-off annoyances, immediate implementation, or unverified patterns without evidence.
Use this skill when an action may write externally, delete, overwrite, force-push, deploy, migrate, touch secrets, affect production, access customer/client data, or when the permission tier is uncertain. Do not use for read-only inspection or drafting that clearly stays local.
