Apply to any non-trivial work, not just bulk work: edits, migrations, analyses, checks. Build the tool that does it or proves it (codemod, script, generator, or a skill your subagents follow) instead of working by hand. The tool is the artifact a reviewer can rerun.
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
# Build the Lever When the work isn't trivial, build the tool that does it instead of doing it by hand. A codemod, generator, or script does the work the same way every time and reruns for free. The tool is one artifact a reviewer can read and rerun to check the work. Hand-done changes can only be re-verified by redoing them. A deterministic script turns "trust me" into "run this". Default to building the lever. Skip it only when the task is trivial, a couple of obvious edits you can see at a glance. - Do the first unit by hand to learn the recipe, then build the tool. Prove it by rerunning it on that unit and diffing against your hand-done version. Make the lever safe to rerun. - For a comparison tool, seed one known-bad change for each output it claims to compare, and confirm the tool reports each mismatch. For example, change a total, then separately swap item assignments while keeping the totals. If required input is missing, the tool must refuse or report the result as inconclusive, never as a match. Keep these controls with the experiment and rerun them before you trust its results. …

How to install
mdr add michael-denyer/pstack-claude/principle-build-the-lever@sha256:9dc489b420ff2d4eThe line at the top of this page pins the label git:20261017.140bbd5, 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.
