Dependency rating derived
allow — alive & usable · orchestration ● · V n/a
Cluster mid-fast-shared · distinctiveness 0.669 (unusual). Every figure is a percentile or class within the 11,094-server census — see the whole spectrum.
🔏 Signed receipt rr_0f186baad277e940de845c4a · 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, 2026-08-12 → 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.

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 |
|---|---|---|---|
| orchestration | 13 | routes other tools | identity + fronted-service disclosure checks (gateway vs costume) |
| retrieval-public | 9 | serves public facts | truth-checkable against a public source — the V-ladder applies in full |
| action | 1 | changes the world | no true answer exists; we check the CONTRACT (destructive/read-only/idempotent declarations, error legibility) and never fire real actions |
| computational | 1 | deterministic transforms | self-checkable by re-computation and known-answer tests |
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 | 24/24 | ✓ |
| has a description | 24/24 | ✓ |
| description is substantive | 24/24 | ✓ |
| parameters are typed | 24/24 | ✓ |
| parameters are described | 24/24 | ✓ |
24 of 24 tools graded · 24 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.
Protocol conformance observed
Capabilities: prompts resources tools
Drift observed
No confirmed drift on record. Baseline set 2026-08-14; changes appear here after human review.
