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
MERCADOLIBRE_CLIENT_SECRET or --client-secretConfiguration, not credentials: MERCADOLIBRE_ACCOUNT, MERCADOLIBRE_CLIENT_ID, MERCADOLIBRE_REDIRECT_URI, MERCADOLIBRE_SITE_ID
Where it talks to
mercadolibre.com (its own)
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.
