🔏 Signed receipt rr_50310e0d3edb6905f3f62856 · 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 (3 shown, 2026-08-23 → 2026-09-06). 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 tool names/descriptions/annotations WE OBSERVED. What checking applies to each kind (the full methodology →):

naturetoolsmeaning what checking applies
retrieval-public21serves public factstruth-checkable against a public source — the V-ladder applies in full
action8changes the worldno true answer exists; we check the CONTRACT (destructive/read-only/idempotent declarations, error legibility) and never fire real actions
unclassified3not classifiable from its textTier-1 only until its tools describe themselves
generative2creates contentno answer key exists; disclosure + stability checks, never truth verdicts
predictive1claims about the futurescoreable only in retrospect — the archive scores yesterday's predictions against today's outcome

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.

legibility checktools passingok
name is clear & specific35/35
has a description35/35
description is substantive35/35
parameters are typed35/35
parameters are described5/355/35

35 of 35 tools graded · 35 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.
