One taste. Genuinely different instructions.

Lovable-tuned · semantic tokens, shadcn primitives, Tailwind

• Lovable build brief
• How to use:** paste this into a fresh Lovable project as the first message.
• Stack assumed:** React + Vite + Tailwind, shadcn/ui, semantic CSS variables in `src/index.css` (or `src/styles.css` on TanStack).
• Token discipline:** never use raw colors in components — only semantic tokens (`bg-background`, `text-foreground`, `text-accent`).
• Creative direction
• Implementation constraints
• Define every color as an HSL or OKLCH CSS variable in the global stylesheet and mirror in tailwind.config.ts.
• Compose every component from shadcn/ui primitives; never re-invent Button, Input, Dialog, Card, or Tabs.
• Implement all motion through framer-motion without using bespoke CSS keyframes for state transitions.
• Maintain mobile-first responsiveness at 360, 768, and 1280 pixel breakpoints.
• Use lucide-react for iconography and sonner for toast notifications.
• Build small, focused components in src/components/ rather than large monolithic pages.
• Reference the project's llms.txt file to discover available documentation before proposing changes.
• Enable 'Execute backward incompatible database migrations' in Cloud permissions to allow dropping or renaming tables.

Cursor · .cursorrules format + file-tree expectations

• .cursorrules — generated by My Vibe Design
• Design north star
• Rules Cursor MUST follow
• Ensure your computer is plugged in and the lid is open when using 'Keep this computer awake' for remote control.
• Enable Rollouts and Security Reviewer from the Automations tab in the dashboard for Teams and Enterprise plans.
• Connect source control, deployment systems, and telemetry providers to enable automated change monitoring.
• Define custom team rules in the dashboard to ensure Security Review enforces specific architectural constraints.
• Invoke Custom Modes using the / menu and Alt+Enter to pin specific skills for the duration of a chat.
• Install necessary desktop packages on self-hosted workers to enable computer use features on Linux and Mac.
• Pair the iOS app with the desktop client and approve the pairing request to enable remote monitoring.
• Enterprise admins must manually enable Remote Control in Org settings under Security and identity.
• Use the Origin Apps plugin to plan ports of existing apps to the Origin platform.
• Latest Cursor capabilities
• Integrate with the Origin App Marketplace to connect tools for CI, security, monitoring, and deployments.

v0.dev · React + Tailwind + shadcn, single-shot component

• v0 build brief
• How to use:** paste into v0.dev as a new generation.
• Output expected:** a single React + Tailwind + shadcn/ui composition.
• Creative direction
• Component requirements
• Use the App Router and React Server Component idioms; mark interactive leaves with 'use client'.
• Compose from shadcn/ui primitives like Button, Card, and Input rather than re-inventing them.
• Apply Tailwind utility classes only; avoid styled-components, CSS modules, or inline style props.
• Use lucide-react for icons and inline SVG for decorative ornaments.
• Design for mobile-first responsiveness and keep compositions self-contained.
• Use the slash-command menu to explicitly attach specific skills for complex logic.
• Click the compact error bar beneath the preview to debug VM dev server boot or install failures.
• Configure default chat visibility in Workspace Settings to control team access for new chats.
• Use the branch menu to fix preview, CI, or merge issues without leaving the chat.

Claude Artifacts · XML-tagged, single self-contained artifact

• <role>
• You are a senior product designer + frontend engineer. Produce a single, self-contained Claude Artifact that realises the creative brief below.
• </role>
• <creative_brief>
• </creative_brief>
• <output_contract>
• Use the computer_toolset_20260801 toolset for computer use as earlier versions like computer_20250124 are deprecated.
• Avoid using temperature, top_p, top_k, or assistant prefill with Haiku 5.5 to prevent 400 errors.
• Ensure all entries in a web tool's allowed_domains are explicitly matched within the environment's allowed_hosts.
• Set thinking.display to 'summarized' to view thinking block text, otherwise it is omitted by default.
• Include the managed-agents-2026-04-01 beta header when enabling dynamic workflows for Managed Agents.
• Return exactly ONE artifact of type application/vnd.ant.react or text/html per response.
• Ensure artifacts run standalone without external imports beyond React, Tailwind, and inlined SVGs.
• Use the effort parameter to control thinking depth as thinking cannot be disabled on 5.5 models.
