I built a small tool for people using Replit Agent / other AI tools.
It’s called TraceMap.
The problem I kept hitting with vibe coding is not “can the AI write code?”
It can. Very quickly.
The problem is knowing what to ask next and giving it the right repo context before it starts changing files.
TraceMap lets you paste a repo, maps the main feature flows, then turns a feature idea into a step-by-step Prompt Plan you can paste into your coding agent.
So instead of saying:
“add payments”
and hoping for the best, you get prompts like:
inspect this existing flow first, do not change code yet
update these data/model files
add this service/API logic
update this UI path
add tests
run checks and fix only related regressions
It also generates context packs with relevant files, insertion points, risks and test gaps.
The idea is simple:
context before code
I built it during the Replit Buildathon and I’m probably going to keep using it myself.
Would love feedback from anyone doing serious vibe coding / agent-assisted building. Seriously had some great feedback and have been able to make changes already!
