# suit-hud-frame-compose

`station__suit__suit-hud-frame-compose` · external (needs EXECUTION_BACKEND_URL configured) · domain `suit` · pv-relevance `non-pv`

Compose a HUD frame from sensor data — attitude (pitch/roll/heading), systems health (power/thermal/integrity), threat markers, and nav waypoints.

> **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.
