Thank you for the specific report, it found a real problem. ChatGPT keeps the list of tools from when the Saillogger app was added, and it caps the size of that list; the two new reads pushed ours just over the cap, so ChatGPT kept your old list even after you reconnected. This a ChatGPT specific limitation, other agents don't exhibit that but there were options on our end so that is fixed on our side now.
To pick up the new tools, open ChatGPT’s Settings > Apps > Saillogger and press Refresh, then start a new conversation. Reconnecting alone does not update the list. You should then see “Trip readings, fix by fix” (get_trip_samples) and “Sailing readings across trips” (list_sailing_samples). For trips 52048 and 52059, each row carries time, latitude, longitude, SOG, COG, apparent wind speed and angle and whether an engine was running; engine RPM comes along if you ask for it by name.
