AI doesn't lose your code. It loses your decisions.
The output gets saved; that’s the easy part. What doesn’t survive is the reasoning. The moment you choose one approach over another, the constraint you agreed on, or the scope you explicitly ruled out, all of it disappears when the conversation ends.
I came across this building TrekCrumbs, a cross-platform travel app I built over five months with ChatGPT as my development partner. The code was solid. The velocity was real. But underneath, problems were building up in ways I hadn’t noticed.
Early on, I made a decision about how to structure the data: by creating separate schemas for each type of crumb (Crumb: a category of travel activity, lodging, flight, train, etc.). It made sense at the time; it was flexible, clean, and easy to extend. That decision lived in a chat I never reopened.
A few weeks later, I made another decision that depended on the first one without realizing it. Then another. Fields drifted between schemas. Validation logic duplicated. Small changes started breaking things that seemed unrelated. ChatGPT kept offering fixes: mapping layers, UI patches, converters. All technically correct. All making the real problem worse.
The real problem was simple: a key decision was made in a conversation, never documented, and quietly influenced everything afterward. When the cost showed up, it came all at once.
I stopped for a week. Not to add features or fix bugs. To rebuild the schema from the ground up. A full week of stepping back, normalizing the data model, and figuring out how everything should actually work from start to finish. That week wasn’t about coding; it was about making decisions that should have been written down months earlier.
Once the architecture was clear, the AI carried out the refactor quickly and cleanly. That was never the bottleneck. The bottleneck was that decisions lived in chat, and chat doesn’t lend itself to building upon previous conversations effectively.
So I created the Trail Framework (Trail).
Trail replaces conversations with artifacts. You define intent up front. Who decides, who plans, who builds, and who reviews are separated by design. Work is carried out through structured runs that generate auditable files. Every decision is documented, preserved, and able to be verified.
The core idea is simple: conversations drift, but files do not. AI can carry out tasks, but it’s a weak decision-maker and an even worse historian. Reliability comes from explicit artifacts, role separation, and smooth handoffs.
Trail is not a project management tool. It’s not a methodology. It doesn’t replace Git, Agile, or anything you already use. It sits above all of that and enforces one rule: decisions don’t live in chat.
Trail is open source.
