Deterministic code generation for AI coding agents
Your agent decides what to build. A schematic decides how, and writes exactly the same files every run. Typed, testable and idempotent, so you review the schematic once instead of every generated file.
builder execute default:hello --name=payments~ services.txt~ src/services/payments.ts✓ done — 2 modifiedRun it again with --name=orders and services.txt grows by one
line. Re-run the same name and it fails closed, so nothing is written twice.
The same schematic with the same input always produces the same bytes.
