idea-refine
by addyosmani
Refines raw ideas into sharp, actionable concepts through structured divergent and convergent thinking. Use when an idea is still vague, when you need to stress-test assumptions before committing to a plan, or when you want to expand options before converging on one. Triggers on "ideate", "refine this idea", or "stress-test my plan".
api-and-interface-design
by addyosmani
Guides stable API and interface design. Use when designing APIs, module boundaries, or any public interface. Use when creating REST or GraphQL endpoints, defining type contracts between modules, or establishing boundaries between frontend and backend.
ui-core-components
by open-metadata
Use when writing or editing React/TSX in openmetadata-ui/src/main/resources/ui/src/ or openmetadata-ui-core-components/, before reaching for a raw + Tailwind utility classes to build layout (flex rows/columns, grids, bordered panels with header/body/footer, separators), and before writing any Tailwind color class (tw:bg-, tw:text-, tw:border-*) or hex color value. Applies whenever the change adds or restructures a layout container or touches color/dark-mode styling, not to every div.
mastra-frontend
by mastra-ai
How to build Mastra frontend interfaces with the @mastra/playground-ui design system. This skill should be used when creating or modifying any application UI — pages, components, styling, or tokens — in this repo or in an external consumer of the design system. The docs site has its own styling and is out of scope.

customer-support-agent
by mastra-ai
Authoring playbook for building agents that triage and reply to customer messages — support tickets, email inquiries, chat questions, refund requests, or product issues. Use this when the user wants an agent that handles inbound customer questions, drafts replies, escalates hard cases, summarizes tickets, or follows a support playbook.

agent-testing
by lobehub
Agentic end-to-end testing for any project: backend verification via the project CLI, frontend verification via agent-browser (web), and desktop verification via CDP (Electron). Drives the real surface, captures visually confirmed evidence, and publishes a structured report to LobeHub Acceptance. Triggers on 'cli test', 'test with cli', 'verify with cli', 'backend test with cli', 'local test', 'test in electron', 'test desktop', 'manual test', 'test report', or any local end-to-end verification task.
design-prototype
by lobehub
Produce an interactive single-file HTML design prototype using the REAL LobeHub design system (@lobehub/ui + antd + antd-style tokens) with production-style React — no build step, opens directly in a browser. Use when asked for a design prototype / interactive mockup / 交互原型 / 出个原型 / 设计稿 HTML for a page or flow, or to explore a redesign before committing to implementation.
product-design
by lobehub
'Turn a vague product ask ("this page feels wrong", "we need a team view") into a grounded, shippable design by establishing business semantics and the user task before proposing a surface. Use when scoping a new surface, redesigning an existing one, or deciding what a feature should be. Not for auditing a built screen (ux-audit) or choosing visual details (ux).'
ux
by lobehub
'LobeHub product design values / principles / checklists. Use whenever the work touches user-interface features or implementation — designing or building any user-facing flow — to get better UX results.'
ux-audit
by lobehub
'Audit a page / surface against the Designing Interfaces pattern language + the ux skill checklists, then land findings. Three layers — static (code), visual (screenshots), dynamic (automated user journey + perf). Use to run a repeatable, standards-based UX review of one screen.'
deep-review
by lobehub
'Multi-dimensional code review. Use when the user asks to review, evaluate, or audit a PR, diff, branch, or pasted change — including informal review asks like "look at this change for problems" — via light mode: one independent reviewer against the dimension quick checklists. Not for explain-only questions about what a change does or why. Deep mode runs only on explicit invocation (/deep-review), and normally at most once per logical requirement.'
