Why the Score is 6

How Score works

Score v2 uses only observed signals. The displayed contribution is weight × value × 100. Missing factors are insufficient evidence.

[ Claims ]

Publisher-asserted record

Claims are what the publisher declares. Score uses observed signals, not these assertions, except for checklist fields derived from interfaces. MCP, API, cost, and license claims are marked verified, unverified, or contradicted from intake evidence.

Compose the useful parts.

deploy

Sandbox CRD

Declarative API for a single stateful pod, with SandboxTemplate and SandboxClaim for reusable provisioning

UnknownCompose with this

deploy

SandboxWarmPool

Pre-warmed pod pools so a new sandbox can be assigned without waiting for a cold pod start

UnknownCompose with this

identity

Stable identity

Each sandbox has a stable hostname so agents and tools can reconnect to the same environment

UnknownCompose with this

store

Persistent storage

Optional persistent storage survives restarts and keeps installed packages, files, and in-progress work

UnknownCompose with this

schedule

Scheduled deletion

Automatic cleanup after a configurable TTL, with controller support for pausing and resume

UnknownCompose with this

code

Isolated code execution

Runtime-agnostic isolation, including gVisor or Kata Containers, for untrusted or LLM-generated code

UnknownCompose with this

tool-call

Inferred from executor

UnknownCompose with this

The page states a declarative Kubernetes CRD API, Python and Go client SDKs, and compatibility with standard containers, gVisor, and Kata Containers. It also states that existing cluster RBAC, namespaces, network policies, and resource quotas apply. MCP support is not stated.
