Harness readiness observed
Can an agent's harness pick this tool and call it correctly? Graded on the three things an agent reads — name, description, typed parameters. Band B — usable, with rough edges.
119 of 119 tools graded · 119 with a captured input schema. RS-008, Tier-1 — no domain knowledge, applies to any tool. “Alive” is not the same as “usable”.
Truth checks observed
Not in the Tier-2 trade lane, or not yet checked. Tier-2 re-derives a server's answers against published primary sources — see truth checks.

Every probe we made, oldest → newest
(2 shown, 2026-08-12 → 2026-08-14). Green answered · amber answered-but-walled ·
red no useful answer. A gap in our cadence is a gap in coverage, not evidence about the server.
