Layered implementation order (cake model).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Implementation order

For **new behavior**, the **workflow rule** wins on red-green order. Use this file to decide **where** code lives and which layer to extend first.

1. Extend the **lowest** layer that can own the change with no new upward dependencies.
2. Add tests at that layer before or with the change (see the **testing rule**).
3. Wire through **`internal/agent`** or **`internal/acp`** only after lower pieces exist and pass tests.
4. Optional HTTP surface - last mile in **`external/httpserver`**, then refresh **`openapi.go`** and docs per the **API-layer** and **workflow** rules.

## Forbidden

- Skipping tests for new behavior.
- Placing domain logic in **`cmd/`** or duplicating it in HTTP handlers instead of reusing **`internal/`** APIs.

How to install

The exact contents, by fingerprint
mdr add coddy-project/coddy-agent/.cursor/rules/implementation-order.mdc@sha256:4da6f68a47c42fb1

The line at the top of this page pins the label git:20261004.8e8554b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
