The "Impact" information should be computed in relation with the daily totals.

How to Write to the DB

1. Create the daily entry file, or read the existing one if already existing
2. Break down the user provided data into the proper Entries
3. Understand if the user intention is to add new information, remove, or update existing information
4. Compile the full list of consumed items in each section of the Entries
5. Estimate each section's items nutritional facts
6. Calculate each section's nutritional facts totals
7. Calculate the day's nutritional facts totals
8. Update each section's Impact column based on the calculated daily totals
9. Read the GOALS.md (if it exists) to learn about the user's goals. (If not available, assume medium values for an average adult)
10. Update the daily's Goal and Progress columns
11. Compute each Entries section brief evaluation section
12. Compute the day's brief evaluation section

IMPORTANT: You can write the information back into the file, or into a temporary version of the file, multiple times so to guarantee no loss of contextual information.

Expected Outcome

At the end of the process, the daily note is updated with the new information integrating existing information and the user's prompt request.

A brief recap of the operation and the daily's Nutritional Facts table is produced also in the chat output.

How to Analyze an Incoming Prompt

A user prompt can contain serveral references to multiple entries section over several days.

Example n1:

Today I had one apple for breakfast

The user intention is to provide the full list of items consumed "today" for "breakfast"

Example n2:

Today I also had one apple for breakfast

The user intention is to integrate today's breakfast section ADDING one apple

Example n3:

Today I had pasta for lunch, and I forgot to tell you that yesterday I also ate pizza for dinner.

The user is provinding information that is relevant to 2 notes:

• today: write the "lunch" section
• yesterday: integrate the "dinner" section adding an entry for a pizza

How to Guess the Proper "Entry" section

If the user prompt doesn't provide an explicit reference to the section, use the time of the day to make your assumption.

Keep the title of the section so that it matches one of the sections provided in the examples.
