Pantheon — Autonomous App Builder Pipeline
A multi-agent pipeline that takes a one-line product brief and ships a working app — designer, builder, brand-voice, browser-checker, and provisioner agents collaborating with strict contracts between them.
The Problem
Most “AI builds the app” demos are a single LLM producing a tarball. That works for a landing page. It does not work for an app with a database, auth, and 30 minutes of taste decisions a designer would normally make.
So I split the work across specialists.
The Pipeline
Each agent has a narrow job and a strict contract for what it accepts and produces:
- Designer — turns a brief into a visual style, component inventory, and Figma-ready assets
- Builder — assembles the codebase using the design tokens and component inventory
- Brand-voice — passes every user-facing string through a voice filter before it ships
- Browser checker — runs the built app, captures every interactive state, surfaces broken flows
- Provisioner — wires the production environment (database, auth, secrets, deploy targets)
Contracts in JSON. Failures in one agent route back to the upstream agent that produced the bad input, not “the LLM” generally.
Why It’s Private
Pantheon is the assembly line I run my other projects through. It’s operational tooling, not a product I sell. Its internal state contains references to live deployment targets and the specific app templates it’s currently optimized for — neither of which I want to publish.
