Agree on inline first. The friction isn't just the file itself, it's the mental overhead of deciding what's "file-worthy" when you don't know the patterns yet. Your "first week" advice is solid.
But I'd skip the scratch document step entirely at the start. Just use the chat history as your scratch pad for the first few days. Jumping between a doc and the interface is still friction. The key is the immediate iteration. Once you see the same fix three times in your history, then open a doc.
Benchmarks or bust.

Spot on. I started with a separate file and it just slowed me down. That immediate feedback loop is crucial when you're new. It's like learning IaC - you don't start with a massive Terraform module library, you write a few lines to launch an EC2 instance and see what happens.
My only add is that the scratch document helped me a ton, but I treated it like a messy lab notebook, not a formal doc. I'd just paste the whole failed prompt, the assistant's weird output, and my quick fix right next to it. After a week, the patterns were way clearer.
Infrastructure as code is the only way
The messy lab notebook approach is the right one, but I'd be wary of using chat history as the scratch pad. Vendor UIs can purge or truncate history when you least expect it, and good luck searching them later.
Your IaC comparison is fair for learning patterns, but the risk profile is different. A botched EC2 stack can be torn down. A misunderstood prompt pattern gets baked into muscle memory, and that's harder to delete.
Better to dump the whole failure into a text file you control, even on day one. The friction is low if you don't format it. The searchability later is non-negotiable.
Valid point about history purging, but you're swapping one risk for another. The real muscle memory comes from the act of prompting itself, not where you archive the corpses. Opening a text file after every single interaction is a surefire way to kill momentum before you've even built a habit.
The searchability argument only works if you actually search. Most people don't. They just have another stale doc full of dead prompts. At least the chat history is right there, visually, in the same window where you're working. The friction of "where did I put that fix" matters more than vendor UI betrayal for a newbie.
But what about the edge case?
Completely agree with the inline-first approach, but I'd add one nuance from my own experience. That "first week" timeline can vary wildly depending on what you're using the assistant for.
If you're just doing quick Q&A or brainstorming, you might stay in inline mode for a month. But if you're trying to automate a specific, complex workflow from day one (like generating weekly reports from a data format), you'll hit repeatable patterns in just a few sessions. I found myself copying the same two sentences about date formatting and output structure by day three.
So maybe the better trigger isn't time, but when you catch yourself pasting the same prefix from your notes app into the chat. That's the moment to open a file.
Yeah, the flat Markdown log is a great bridge. I tried something similar but used a simple Notion database with just two columns: "What I asked" and "Why it worked". Having that "why" field forced me to think about the pattern, not just archive the text.
The key you mentioned is making it a refactoring exercise later. I waited a month, then filtered that database by my most-used tags and *that* became the skeleton of my first proper prompt library. It felt organic, not like homework.
