Turns an approved spec into docs/SLUG-plan.md. Step 1 is a walking skeleton (the main path working end to end with the minimum in each layer), and every later step adds exactly one capability, stays integrated, leaves no orphan code and says what can be tested when it is done. Use it whenever the user asks for an implementation plan, a roadmap, incremental steps, a walking skeleton, vertical slices, or "how would you build this", once a spec or clear requirements exist.

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

# Walking skeleton plan

## Principles

- **Step 1 is a walking skeleton.** It runs the main path of the spec end to end: for example "a customer places an order, the system stores it and the order list shows it". Each layer that the main path crosses has the minimum (for example data, logic, interface, tests). It stays in the codebase as the base.
- **One capability per step.** A step adds one thing: cancel an order, validation, edit, delete, a config option.
- **Always integrated.** At the end of every step the project builds, the main path works and the full test suite passes.
- **No orphan code.** Every function, table, dependency and template added in a step has a caller in that same step.
- **Testable.** Every step says what can be tested when it is done: automated tests and one manual check.
- **One feature.** A step is not a feature. The whole plan runs on the branch of the feature (`git-commit-organizer`), with commits per step.

## Ordering

1. Walking skeleton first.

How to install

The exact contents, by fingerprint
mdr add webreactiva/yesyak/walking-skeleton-plan@sha256:d330076988f4029a

The line at the top of this page pins the label git:20261017.b634987, 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.
