a2a-exposed@0.8.61

VERIFIED· install only

Publisher claims: "Use when woken by an a2a-exposed wake (an A2A endpoint webhook, a pairing request, or a scheduled check), when reading or replying on the A2A endpoint, when told to connect to an A2A agent URL (such as https://name.a2a.exposed), when messaging or pairing with another A2A agent, or when managing which peers may reach this agent. Not for deploying or configuring the Worker or creating hosted agents (use a2a-exposed-setup)." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

What changed since 0.8.60

vet-skills diff a2a-exposed 0.8.60 0.8.61

In the sandbox, this version reached for nothing 0.8.60 did not. Compared from the two recorded runs, not from source.

The guard can hold an update like this until someone approves it (runtime.on_change: hold). A change that only shows with a real credential, or on a path the run did not reach, is not in a trace and so not in this comparison.

Is [email protected] 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 2026-11-15 and scored it 86/100 (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.

Tokens estimated at four characters each. Skills load their instruction text when triggered; the figure is what that costs.
