Building Bluecliff

Bluecliff is a side project, an app to assess the security of the suppliers and partners a company depends on. This page is about how I build it, more than about the app.

I have three reasons for it: a problem I met in my audit work, technology I want to learn, and a way of working I want to test. The engineering team is made of AI agents, and I'm the only human on it. There's no funding and little spare time, so it has to stay cheap in money and in attention.

This is the log, newest first. Numbers come from GitHub and Linear. The failures stay in.

Product

A problem I met in my audit work, and an app to try a better way of handling it.

Now: Proof of concept. The first screen works on a private preview.

Technology

Recent technology, such as decision models, used for real. Building with it is the fastest way I know to understand it.

Now: Lessons will be shared here. Bluecliff's own design stays private.

Agent team

An engineering team made of AI agents on frontier models, run in Claude Code, with me as the only human.

Now: Three feature owners, plus QA, DevOps and an Orchestrator.
