plan from jrenaldi79/harness-engineering is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Create an implementation plan before writing any code.

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

## Plan Before Build

1. Read the requirements carefully
2. Break down into discrete tasks
3. Identify affected files
4. Write failing tests first (TDD)
5. Implement one task at a time
6. Verify each task with `npm test` before moving on

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add jrenaldi79/harness-engineering/plan@sha256:89df3a1a1c921263

The line at the top of this page pins the label git:20260323.d683468, 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.
