AI reading, beta: AI adds items here; it never removes one.

No tool is read as one of the six effects. A zero is a count, not a clearance.

Exact state: valid · 1 retrieved artifact
A usable protocol document was retrieved and validated.
Directly observed
A2A
absent
Exact state: not found · 0 skills
The supported discovery location returned no matching document.
Not found does not prove the service exposes no such interface elsewhere.

Exact state: unreachable · Tool inventory unavailable · resource inventory unavailable · prompt inventory unavailable
The supported discovery location did not provide a usable response within the observation boundary.
An unreachable result does not prove the service is unavailable to every client or that it advertises no capabilities.

Snapshot generated: 4 Nov 2026, 11:20 UTC

The entry is one exact observed target, not a real-world service identity, and implies no ownership. Endpoint paths are not published; the locator hash lets an operator confirm their own URL.
