[Question]: How do I chain/combine outputs before passing them on to the next step?

What is your question?

First, thank you for this great project. I wanted to try it out for a long time and finally could do so, and I love it.

However, I hit a small roadblock. I wanted to adapt the output of one of the patterns a bit before passing it on to my Obsidian vault. Concretly, this is what I want to do:

1. Get the transcript of this video: https://www.youtube.com/watch?v=q1qKv5TBaOA&ab_channel=Coderized
2. Summarize the content.
3. Add examples to each of the points. Possibly, improve the prompt.
4. Pass on to Obisidian.

Currently, my attempts look like this:
echo "Extract the whole knowldege of the video. Especially the seven deadly sins and how to avoid them. I want to keep that knowledge easily understandable and retrievable in my Obisidian vault. For each Sin, come up with an example. Properly format the output." | improve_prompt | yt https://www.youtube.com/watch\?v\=q1qKv5TBaOA\&ab_channel\=Coderized | summarize | save " How principled coders outperform the competition"

If I understood the tool correctly, I lose my initial and improved prompt between improve_prompt | yt https://www.youtube.com/watch\?v\=q1qKv5TBaOA\&ab_channel\=Coderized because I then pass on the transcript without my improved prompt.

In essence: How can I adjust the patterns using custom instructions on the fly without having to add custom prompts?

Thank you very much for your time and help with this.

Hi Michael!

I played around with your idea and was able to do the following (multi-step in the terminal):

Step 1: Define the initial prompt:

initial_prompt="Extract the whole knowledge of the video. Especially the seven deadly sins and how to avoid them. I want to keep that knowledge easily understandable and retrievable in my Obsidian vault. For each Sin, come up with an example. Properly format the output."

Step 2: Pipe the initial prompt to the 'improve_prompt' pattern and save the output:

improved_prompt=$(echo "$initial_prompt" | improve_prompt)

Step 3: Extract the YouTube transcript and save it into a variable:

video_transcript=$(yt "https://www.youtube.com/watch?v=q1qKv5TBaOA&ab_channel=Coderized")

Step 4: Concatenate the improved prompt with the video transcript:

combined_text="$improved_prompt
$video_transcript"

Step 5: Pipe the combined text into the summarization pattern:

echo "$combined_text" | summarize "How principled coders outperform the competition"

It is not a long piped instruction but 5 separate instructions that work quite well!
Hope it helps!

I'm not sure if this is what you're trying to do but here's how I would try this:

❯ echo "Extract the whole knowldege of the video. Especially the seven deadly sins and how to avoid them. I want to keep that knowledge easily understandable and retrievable in my Obisidian vault. For each Sin, come up with an example. Properly format the output." | improve_prompt -o improved_prompt.txt && echo "$(cat improved_prompt.txt && yt https://www.youtube.com/watch\?v\=q1qKv5TBaOA\&ab_channel\=Coderized)" | summarize >> ~/path/to/vault/"How principled coders outperform the competition.md" 

I hope this helps

Thank you two for your answers and your inspirations, in the end I came up with this solution, and it should be useable for all kinds of similar problems:
General Approach:
echo "$(command1) $(command2)" | <fabric_command>

Translated to my problem:
echo "$(echo "Extract the whole knowledge of the video. Especially the seven deadly sins and how to avoid them. I want to keep that knowledge easily understandable and retrievable in my Obisidian vault. For each Sin, come up with an example. Properly format the output." | improve_prompt) $(echo "\nINPUT: \n") $(yt https://www.youtube.com/watch\?v\=q1qKv5TBaOA\&ab_channel\=Coderized)" | ai | save "7 deadly sins of programming"
