# analyze-state

`station__primitives__analyze-state` · external (needs EXECUTION_BACKEND_URL configured) · domain `primitives` · pv-relevance `non-pv`

Analyze a concept through the State primitive. Identifies observable states, transitions, and distinguishability. State is the variable before boundary fixes it — what can change.

> **Note:** This tool routes through an external execution backend. If `EXECUTION_BACKEND_URL` is unset on the server, calls return JSON-RPC error `-32603 "Tool execution backend not configured"`. Tools with `backend: native` execute in-process and are always callable.
