🔏 Signed receipt rr_b80117f2ebf3053ac864c101 · 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 18 tools, classified, with what checking applies to each kind (the full methodology →):

naturetoolsmeaning what checking applies
computational8deterministic transformsself-checkable by re-computation and known-answer tests
action5changes the worldno true answer exists; we check the CONTRACT (destructive/read-only/idempotent declarations, error legibility) and never fire real actions
retrieval-public3serves public factstruth-checkable against a public source — the V-ladder applies in full
generative2creates 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.

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 (1 shown, 2026-08-14 → 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.
