backdraw@2.4.0

CAUTION· static only

Publisher claims: "Lets Claude and other MCP clients generate and edit images with your own signed-in ChatGPT account in a background Chrome tab. No API key, no open ports; right-click reference collections and a gallery side panel. Windows + Chrome." Observed in sandbox: static analysis only — behavior not yet observed.

Coverage

Static only; nothing was run yet.

The label rests on the code, the instruction files and the publisher. The honeypot run replaces this verdict when it completes.

Before you give it your token

It will ask for
no credential variables read in the code
Where it talks to
no vendor host named in the codeAlso chatgpt.com — not the publisher's domain; check what for before connecting.
What the honeypot saw
nothing has run yet
What we could not test
everything: the server has not run yet

Run it before you trust it. Nothing has run yet: the code was read, the server was not. `vet-skills try` runs this exact version in the honeypot in about a minute.

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills analysed it statically (a sandbox run is pending) on 2026-11-14 and scored it 60/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Hidden zero-width characters detected. Summary: static analysis only — behavior not yet observed.
