Core Philosophy

The Principles

Seed → Validation harness → Feedback loop. Tokens are the fuel.

Entry Point

Seed

Every piece of software needs an initial seed. Historically, you might have called this a PRD or a spec. Today, this could equally be a few sentences, a screenshot, or an existing codebase.

The Loop
1
Validation

Your validation harness must be end-to-end, as close to the real environment as possible: customers, integrations, economics.

2
Feedback

A sample of the output, fed back into the inputs. This closed loop allows your system to self-correct and compound correctness.

The loop runs until the holdout scenarios pass (and stay passing)
The Fuel

Apply More Tokens

The theory of Validation and Feedback is easy to understand. The practice requires creative, frontier engineering. For every obstacle, ask: how can we convert this problem into a representation the model can understand?
