Summary
Sleek is an API-first mobile app design tool that lets Claude build UI screens through natural language chat. You describe what you want ("add a pricing section with three tiers"), and the API returns rendered HTML components you can screenshot or iterate on. The skill handles both high-level requests ("design a fitness app") and specific operations (list projects, target a particular screen for edits). All network traffic stays within sleek.design, and you control access through scoped API keys. Works best when you need to rapidly prototype mobile interfaces without leaving the conversation. Requires a Pro plan for API access, and responses can be polled async or waited on sync up to five minutes.
