Sleek Design Mobile Apps

Prerequisites: a Sleek account (sleek.design) — paid plan required for sustained use ($49.99/month or $360/year per the skill docs). SLEEK_API_KEY must be saved in the secure vault; never paste secrets here. Install "Sleek Design Mobile Apps" for me. It lets the agent design mobile app screens and UI flows via the Sleek service, and implement Sleek designs in code. Repository: https://github.com/sleekdotdesign/agent-skills/blob/main/skills/design-mobile-apps/SKILL.md 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md (sleek.design only). Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "design-mobile-apps". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. save my Sleek API key in the vault). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
