Dependency rating derived
allow — alive & usable · retrieval-public ● · V3 has answer key ◐
Cluster rich-slow-solo · distinctiveness 0.751 (unusual). Every figure is a percentile or class within the 19,148-server census — see the whole spectrum.
🔏 Signed receipt rr_cd96425ebf5064a0d15059d2 · 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.
● observed · ◐ derived · ○ reported — the verdict synthesizes Q1–Q4; Q5 is context. Methodology →
History observed
Every probe we made, oldest → newest (2 shown, 2026-09-06 → 2026-09-13). 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 | 27 | serves public facts | truth-checkable against a public source — the V-ladder applies in full |
| action | 6 | changes the world | no true answer exists; we check the CONTRACT (destructive/read-only/idempotent declarations, error legibility) and never fire real actions |
| computational | 4 | deterministic transforms | self-checkable by re-computation and known-answer tests |
| generative | 4 | creates content | no answer key exists; disclosure + stability checks, never truth verdicts |
| orchestration | 1 | routes other tools | identity + fronted-service disclosure checks (gateway vs costume) |
| predictive | 1 | claims about the future | scoreable only in retrospect — the archive scores yesterday's predictions against today's outcome |
| retrieval-private | 1 | serves the caller's own data | outside truth-checking is impossible BY NATURE, not by failure — the operator-invited pathway applies |
Tools last seen observed
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 | 44/44 | ✓ |
| has a description | 44/44 | ✓ |
| description is substantive | 44/44 | ✓ |
| parameters are typed | 44/44 | ✓ |
| parameters are described | 40/44 | 40/44 |
44 of 44 tools graded · 44 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 — 3 attempt(s) currently unverifiable (rate limits, walls, or unmappable schemas — never counted against the server) · 0 disagreements.
| claim class | key | verdict | primary source |
|---|---|---|---|
| fx-rates | EURUSD | unverifiable | ecb-fx |
| tariff-duty | 0901.21.00 | unverifiable | us-hts |
| tariff-duty | 6109.10.00 | unverifiable | us-hts |
