Install with caution designed-by-ai/skills

Sleek's mobile design API skill, here as a mirror of the official repo. Needs a paid Sleek plan for real use and sends your brief to Sleek.

Verified · Repo on GitHub

What it does

Lets the agent design mobile app screens through Sleek's REST API (create a project, send a design brief, poll the run, fetch HTML and screenshots) and then implement them in React Native or HTML, with guides for NativeWind, Uniwind and StyleSheet. If no API key is set it walks you through a device sign-in flow.

Who made it / license / last checked

Sleek (sleek.design) — this repo mirrors sleekdotdesign/agent-skills · License: MIT (repo LICENSE) · Repo last commit checked: 2026-10-05

Install

# Official repo, per its README:
npx skills add sleekdotdesign/agent-skills -s sleek-design-mobile-apps

The README inside designed-by-ai/skills is Sleek's and points to sleekdotdesign/agent-skills, so that is the line we list. Requirements per README: a Sleek account and an API key in SLEEK_API_KEY.

What files / scripts it runs

SKILL.md (8,484 bytes) plus designing.md, endpoints.md, implementing.md and three styling guides. No scripts: the agent calls https://sleek.design/api/v1/* with your key (projects, chat runs, screenshots, project deletion).

Pros

  • Well documented API contract, including errors, retries and scopes
  • Device sign-in flow so you never paste the raw key into the chat
  • Asks the agent to show the price before sending you to a payment page

Cons

  • Real use needs a paid plan: the README states Pro at $69/month (or $360/year); free accounts get about one trial design run
  • Your app brief and designs go to Sleek's servers
  • This listing is a mirror: install from sleekdotdesign/agent-skills, where the fixes land first

Alternatives

Designing in Figma or with a design-guidance skill such as anthropics frontend-design, which needs no account.

Sources

Verified on 2026-11-04 through the GitHub API: neither it nor the original it is compared with has had a commit since the 30 Oct check, so the files, sizes and verdict above still hold. Previous check on 2026-10-30, from a fresh clone of the repo (commit 03c20ae, 2026-10-05) and the skills.sh leaderboard fetched that day. Repo last-commit is a repo date, not a per-skill release date. Install counts are distribution, not quality.
