Draft and Build Case Study: Five Files Read, One Spec Drafted, Setups Written for Five Platforms

Tue, 29 Sep 2026 00:00:00 +0000

Most repositories already say what they need. A .python-version file names the Python, requirements.txt the packages, a compose file the databases the developers run, .env.example the variables. What they don’t have is that knowledge in the form an agent platform reads, once for each platform.

In the Alpha demo, orders-api is a small Python service with no setup files for any agent. preconfig detect reads the files it has and drafts preconfig.yaml. preconfig build then writes the setup files for five platforms. The draft turned out to be the spec the team had written by hand, line for line apart from its comments.

Hand-Written Setup Case Study: Fifteen Errors in One Service's Agent Setup, None Flagged When It Was Written

A team that uses two or three agents writes the same setup two or three times: once as a Copilot workflow, once as a Cursor environment, once as a dev container. Each file is written at a different time, from a different example, by whoever needed it that week. Nothing checks them against each other, and most platforms say nothing when a file is wrong until an agent tries to use it.

The Problem Preconfiguration Solves: Coding Agents Start Every Task on a Machine Nobody Set Up

AI coding agents start each task on a blank machine. When that machine isn’t set up, they guess, fail or hand back untested code, and every vendor wants the setup written in its own file.

Agents Are Poor at Doing It Alone

If agents could reliably set up a repository by themselves, the problem would solve itself. The benchmarks say they can’t, yet:
