ui-sdk@r1

VERIFIED· install onlyVerified Publisher

Publisher claims: "Builds interfaces with ui-sdk in React, Vue, Svelte, Solid or web components. Covers choosing and composing its components, building a component or behavior it doesn't ship from @ui-sdk/core (like a stepper, splitter, transfer list or emoji picker), making the interface usable by agents through createAgent, agent tools and WebMCP, and testing keyboard, focus, ARIA, server rendering and right to left, including writing tests for an existing component. Use whenever a project has @ui-sdk/* installed or the user mentions ui-sdk." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Is ui-sdk@r1 safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-13 and scored it 99/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. The publisher is verified. Summary: no network, touches nothing outside the project, writes no memory.
