a2a-exposed-setup@0.8.56

VERIFIED· install only

Publisher claims: "Use when deploying, redeploying, or configuring the a2a-exposed Cloudflare Worker, a wake webhook, polling, or a public façade for an agent that already speaks A2A, or creating a hosted agent on a2a.exposed. Not for reading or replying to messages (use a2a-exposed)." 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 2026-11-14 and scored it 85/100 (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.
