Simple.

Repository truth for coding agents, and a method for making the smallest defensible change.

The Raptor test

Necessary complexity moves inward. Raptor 4 is public; its physical form is not.

Raptor 1, Raptor 2 and Raptor 3 displayed side by side, showing progressively less exposed plumbing.

MacBook unibody

One machined enclosure replaced many structural parts, seams and supports.

Method

Start with reality. Follow the ordinary path. Prove the result.

  1. 01

    Users, promises, data, consequences.

  2. 02

    One owner. One route. One missing capability.

  3. 03

    Observe behaviour outside the implementation.

Commands

Five entry points. All are read-only except init.

simple audit

Split ownership and unpaid complexity.

simple plan

The smallest change the repository can justify.

simple review

Claims tested against repository facts.

simple init

Routing files and an incomplete profile.

simple check

Routing and profile shape.

Evals

Ten cases pair a task, repository facts and a pass/fail rubric.

Measure the decision.

Run the same cases. Score the rubrics. Keep a change only when its target improves without regressions.

SIMPLE.md

The skill holds the method. The nearest SIMPLE.md holds the facts.
