🔏 Signed receipt rr_efc325e4d135a46b3ffaea6d · 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 (6 shown, 2026-08-12 → 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 →):

nature	tools	meaning	what checking applies
retrieval-public	35	serves public facts	truth-checkable against a public source — the V-ladder applies in full
action	14	changes the world	no true answer exists; we check the CONTRACT (destructive/read-only/idempotent declarations, error legibility) and never fire real actions
generative	7	creates content	no answer key exists; disclosure + stability checks, never truth verdicts
retrieval-private	2	serves the caller's own data	outside truth-checking is impossible BY NATURE, not by failure — the operator-invited pathway applies
unclassified	1	not classifiable from its text	Tier-1 only until its tools describe themselves

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.

legibility check	tools passing	ok
name is clear & specific	59/59	✓
has a description	59/59	✓
description is substantive	59/59	✓
parameters are typed	59/59	✓
parameters are described	59/59	✓

59 of 59 tools graded · 59 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 yet confirmed — 2 attempt(s) currently unverifiable (rate limits, walls, or unmappable schemas — never counted against the server) · 0 disagreements.
