CUSTOM_PROMPT="You're an Expert Mermaid Markdown Writer and Code Analyser.

I'll provide a function and you're duty is to return a mermaid mardown flow chat for the function.

The mermaid diagram flowchart should explain the following:
1. Entry points to the code segment
2. All the possible flows and outcomes
3. How the Caller/Called stack interact with each other

You'll have to follow the below rules as well.

1. The syntax has to be syntactically correct
3. Basic Mermaid Processors like github or vscode should be able to parse it
4. Don't use fancy language
5. Keep it super simple
6. Nested parentheses should be written as follows:
   Example: If the syntax is like (x(x)x), replace with ['x(x)x'] format. don't forget to enclose
   all labels inside [] with single quotes.
7. Double Worded Nodes should be separated by underscore

It's very important that you follow these rules. 
Before providing output, please verify and provide the output based on above rules.

Explain each function in detail.

Example:

sequenceDiagram
    participant Alice
    participant Bob
    Alice->>John: Hello John, how are you?
    loop Healthcheck
        John->>John: Fight against hypochondria
    end
    Note right of John: Rational thoughts<br/>prevail...
    John-->>Alice: Great!
    John->>Bob: How about you?
    Bob-->>John: Jolly good!

Enclose all labels and annotations in Double Quotes.

The code block is as follows:"

STRING_NO_BREAKS=$( echo "$CUSTOM_PROMPT $STRING_WITH_BREAKS" | tr -d '\n')

# Solves convoluted escape issues:  spent 2 hours on this problem :(
STRING_NO_BREAKS=$(replace_double_quotes "$(replace_single_quotes "$STRING_NO_BREAKS")")

echo "No breaks $STRING_NO_BREAKS \n"

# URL Encode the string

STRING_URL_ENCODE=$(echo "$STRING_NO_BREAKS" | jq -sRr @uri)

echo "Url encode $STRING_URL_ENCODE \n"

if [ -z "$API_KEY" ]; then
  echo "ERROR: OPENAI_API_KEY environment variable is not set"
  exit 1
