🔏 Signed receipt rr_ae0ffe769ea7113264fc6657 · ed25519 · key rs-rcpt-2026-08 — this rating is tamper-evident; an agent gets the full signature from check_server and can verify it against the published key.

History observed

Every probe we made, oldest → newest (5 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.

What kind of tools these are derived

Verification only means something relative to a tool's NATURE — an email-sender has no "true answer", a generator has no answer key. Classification evidence: classified from the operator's own registry description — REPORTED, not observed (tools were not visible to the probe). What checking applies to each kind (the full methodology →):

Verifiability derived

answer key in hand V3W · confirmed

A public authority publishes the true answer AND we re-check this server against it today. The only grade under which “true” can ever be said. Assessed 2026-08-14T10:05:37Z (human:mrigank) · the full ladder: verifiability.

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 A — an agent can pick and call these reliably.

18 of 18 tools graded · 18 with a captured input schema. RS-008, Tier-1 — no domain knowledge, applies to any tool. “Alive” is not the same as “usable”.

This server doesn't answer, but these live, allow-verdict servers describe themselves similarly — similar by what they say they do — never verified drop-in replacements; check each one before depending on it.
