Dependency rating derived
warn — alive, no tools · kind unknown · V n/a
Cluster alive-toolless · distinctiveness 0.994 (unusual). Every figure is a percentile or class within the 15,472-server census — see the whole spectrum.
🔏 Signed receipt rr_e38670ab4c92a951039d5145 · 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 (3 shown, 2026-08-23 → 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 the operator's own registry description — REPORTED, not observed (tools were not visible to the probe). What checking applies to each kind (the full methodology →):
| nature | tools | meaning | what checking applies |
|---|---|---|---|
| unclassified | 1 | not classifiable from its text | Tier-1 only until its tools describe themselves |
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 B — usable, with rough edges.
| legibility check | tools passing | ok |
|---|---|---|
| name is clear & specific | 5/5 | ✓ |
| has a description | 5/5 | ✓ |
| description is substantive | 5/5 | ✓ |
| parameters are typed | 5/5 | ✓ |
| parameters are described | 0/5 | 0/5 |
5 of 5 tools graded · 5 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: experimental extensions logging prompts resources tools
Drift observed
No confirmed drift on record. Baseline set 2026-09-06; changes appear here after human review.
