avr-check

# /avr:check Run a pre-flight system check to verify all hardware is connected and working. ## Arguments None. ## Workflow ### Step 1 — Run check_system Call the `check_system` MCP tool. This runs all pre-flight checks in parallel: - **Config**: Valid config.yaml present - **miniDSP**: USB device connected + minidspd daemon reachable - **Denon AVR**: AVR reachable (with auto-discovery if host not configured) - **Signal Path**: DSP source/preset matches config (if configured) ### Step 2 — Report results For each check, report: - Pass/fail status - Detail (what was found) - Error message and fix suggestion if failed Format as a clear checklist. ### Step 3 — Troubleshoot failures If any check failed, provide specific debugging guidance: - **Config**: Suggest running `/avr:configure` to configure. - **miniDSP USB**: Check USB cable, try different port, check `lsusb` output. - **miniDSP daemon**: Check if minidspd is running (`systemctl status minidspd`). - **Denon AVR**: Check power, network, try ping. Suggest `/avr:configure` to configure host. - **Signal Path**: Explain the mismatch and what to do about it. ### Step 4 — Overall verdict If all checks pass: "System is ready for calibration." If some fail: "N of M checks failed. Fix the issues above before calibrating." ## Important rules 1. **Always run check_system first.** Don't try to manually check things. 2. **Be specific about fixes.** Don't just say "check the connection" — say which cable, which port. 3. **Suggest /avr:configure** if config is missing or incomplete.
