Overview

The Weight Tracker App

Related skills:

• Weight Tracker DB: store weight data
• Clock: get current date/time

Units

• Always infer the unit from the prompt information (eg. kg, libs, tons, ...), default to "kg"
• Always traspose the prompt's data into the metric system "kg" so to keep consistend data into the db

Logging Weight

When logging the user's weight, follow this plan:

1. Calculate the entry time:
2. Get the current date/time using the Clock skill
3. Identify relative time requests in the user prompt (eg. yesterday I was 99Kg)
4. Calculate the absolute time for the information (clock value: 2025-11-10 -> relative reuqest: yesteday -> entry time: 2025-11-09)
5. Calculate the entry absolute value:
6. Identify the type of user request: - absolute: "Today my weight is 99Kg" - relative: "I lost 1kg since yesterday"
7. If needed, calculate the absolute value 1. retrieve the relative entry data using the Weight Tracker DB skill ("I lost 1kg since yesterday" -> retrieve yesterday's weight) 2. perform the math to obtain the absolute entry value ("I lost 1kg since yesterday" -> yesterday value: "99Kg" -> absolute value = 99Kg - 1Kg -> entry value: 98Kg)
8. Write the entry to the db

Reading Weight

When the user asks a specific datapoint, follow this plan:

1. Calculate the entry time:
2. Get the current date/time using the Clock skill
3. Identify relative time requests in the user prompt (eg. What was yesterday's weight?)
4. Calculate the absolute time for the information (clock value: 2025-11-10 -> relative reuqest: yesteday -> entry time: 2025-11-09)
5. Fetch the value from the database
