asciify-engine@4.33.0

VERIFIED· install only

Publisher claims: "ASCII components, backgrounds and media for the web: loaders, toasts, transitions, animated hero backgrounds, and image, video and GIF to ASCII. GPU-rendered, themeable, framework-agnostic, with an agent skill." 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 2026-11-08 and scored it 90/100 (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.
