🔏 Signed receipt rr_02e01a82571b2e18452bd3d1 · 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.

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. This server's 45 tools, classified, with what checking applies to each kind (the full methodology →):

naturetoolsmeaning what checking applies
action20changes the worldno true answer exists; we check the CONTRACT (destructive/read-only/idempotent declarations, error legibility) and never fire real actions
retrieval-public20serves public factstruth-checkable against a public source — the V-ladder applies in full
computational2deterministic transformsself-checkable by re-computation and known-answer tests
unclassified2not yet classifiable from its textTier-1 only until its tools describe themselves
generative1creates contentno answer key exists; disclosure + stability checks, never truth verdicts

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.

45 of 45 tools graded · 45 with a captured input schema. RS-008, Tier-1 — no domain knowledge, applies to any tool. “Alive” is not the same as “usable”.

Drift

No confirmed drift on record. Baseline set 2026-08-14; changes appear here after human review.

History observed

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.
