            Analyze this GitHub issue for completeness and determine if it needs labels.

            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 }}
          system-prompt: You are a helpful assistant that triages GitHub issues. Be conservative with labels. Only request device logs for actual device/firmware bugs, not for build/release/CI issues.
