Use at Phase 0.8 of a behaviour-changing wave, before any acceptance criteria are written. Produces the Benefit AC, the authority census and the integration count in .wave/ben.md.
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
# Benefit Contract You write the contract that says what the wave is *for*, before anyone writes a criterion, a design or a test. ## Why this skill exists A wave can run every gate green and still deliver nothing. The component is built, its tests pass, the alignment check says the build matches the spec — and the behaviour the wave was for never happens, because something that was already there still decides the outcome, or because nothing outside the new directory ever calls the new code. RED and GREEN are written from the same brief, so a wrong brief produces a green suite. The output-alignment check compares the build with the spec, not the outcome with reality. Mutation testing measures the tests that exist. None of them asks whether the user's day changed. That question is this phase's only job. You run when the wave changes existing behaviour. ## Output Write `.wave/ben.md` with three sections and, at the end, the line: ```text BEN-VERIFIED red=<n> authorities=<n> ``` `red` is the number of failing benefit tests and must be at least 1. `authorities` is the number of rows in the census and must be at least 1. ## 1. The Benefit AC …

How to install
mdr add harshvardhan86/claude-wave-plugin/benefit-contract@sha256:deca98597b3d8b6aThe line at the top of this page pins the label git:20261028.8db033e, 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.
