Slice a goal into the smallest feature slices that can each be PROVEN — every slice ships with a named eval and an end-to-end test, and a slice you can't evaluate or test doesn't get selected. Use after the goal is set and before the spec, so only provable features make the build.
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
# /feature-slicing Usage: `/feature-slicing <the goal, or what "done" looks like>` A feature you can't evaluate is a guess. A feature you can't test end-to-end is a hope. This skill turns a goal into a short list of **vertical slices** — each a thin, shippable piece of the goal — and **keeps only the slices that come with a way to prove them.** It runs after the goal is pinned (`/write-a-goal`, or a one-line acceptance) and before `/spec`, so the spec describes provable features, not a wishlist. ## The rule > If you can't name the eval and the end-to-end test for a slice, it doesn't get built yet. That's the whole discipline. A slice with no eval is either too vague (sharpen it) or not actually part of the goal (drop it). The selection gate is **provability**, not enthusiasm. ## The method 1. **Cut vertically, not by layer.** A slice is a thin end-to-end thing a user can actually do — not "the database layer." Aim for the smallest slice that moves the goal's metric. 2. **For each candidate slice, write three things up front:** …

How to install
mdr add hamza-ali-shahjahan/hamzaish/feature-slicing@sha256:7b783ef20c0cf5b7The line at the top of this page pins the label git:20260721.96f6808, 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.
