candor-ui@2.10.0

VERIFIED· install only

Publisher claims: "Build agent product UIs with Candor UI, a shadcn/ui registry of React components for agents that do real work - chat, tool calls, plans, approvals, diffs, run logs, traces, evals, admin and the app shell around them. Use when building or changing a React or Next.js interface for an AI agent, when the project's components.json lists the @candor registry, or when the user mentions Candor. Covers installing components, choosing the right one, wiring the Vercel AI SDK, Claude Agent SDK or AG-UI adapter, and the honesty rules every Candor screen follows." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-10 and scored it 80/100 (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. Summary: no network, touches nothing outside the project, writes no memory.
