start-logs-device-structured

Task

Prepare for structured device log capture by recording the current timestamp and target device UDID.

Instructions

1. Find a connected physical iPhone:

   xcrun xctrace list devices | grep iPhone | grep -v Simulator | head -1
   

2. Ensure the temp directory exists:

   mkdir -p llmtemp
   

3. Record the current timestamp:

   date '+%Y-%m-%d %H:%M:%S' > llmtemp/.device-log-start-time
   

4. Save the selected device UDID to:

   echo "<UDID>" > llmtemp/.device-log-udid
   

5. Report the start time and device UDID to the user.
6. Tell the user to reproduce the issue, then use the stop-logs-device-structured skill.

Notes

• This skill does not start a background process. It only records state for later collection.
• The app should already be installed and runnable on the target device.
• The follow-up collection step uses sudo log collect, so the user will need interactive sudo access.
