+
+            IMPORTANT: Distinguish between:
+            - Device/firmware bugs (crashes, reboots, lockups, radio/GPS/display/power issues) - these need device logs
+            - Build/release/packaging issues (missing files, CI failures, download problems) - these do NOT need device logs
+            - Documentation or website issues - these do NOT need device logs
+
+            If this is a device/firmware bug, request device logs and explain how to get them:
+
+            Web Flasher logs:
+            - Go to https://flasher.meshtastic.org
+            - Connect the device via USB and click Connect
+            - Open the device console/log output, reproduce the problem, then copy/download and attach/paste the logs
+
+            Meshtastic CLI logs:
+            - Run: meshtastic --port <serial-port> --noproto
+            - Reproduce the problem, then copy/paste the terminal output
+
+            Also request key context if missing: device model/variant, firmware version, region, steps to reproduce, expected vs actual.
+
+            Respond ONLY with valid JSON (no markdown, no code fences):
+            {"complete": true, "comment": "", "label": "none"}
+            OR
+            {"complete": false, "comment": "Your helpful comment", "label": "needs-logs"}
+
+            Use "needs-logs" ONLY if this is a device/firmware bug AND no logs are attached.
+            Use "needs-info" if basic info like firmware version or steps to reproduce are missing.
+            Use "none" if the issue is complete, is a feature request, or is a build/CI/packaging issue.
+
+            Title: ${{ github.event.issue.title }}
+            Body: ${{ github.event.issue.body }}
