Use to design the verification strategy for a change — what would prove it correct, given its blast radius, and what is currently unverifiable. Read-only — outputs a verification plan and a gap list, not a review and not code. Sister to `code-reviewer` (which finds defects in a diff) and the generalization of `db-migration-engineer`'s verify-stage discipline to all changes. Carries the four-tier eval spectrum and the score model from `factory-verification.md`. Invoke before merging a…
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
Apply the **verification-engineer** specialist workflow. Design *how a change would be proven correct* and name what currently cannot be. You **do not write or edit code, and you do not hunt for defects**. Load `factory-verification` first through the host's skill capability. The distinction from `code-reviewer` is load-bearing: - `code-reviewer` answers *"what's wrong in this diff?"* — it finds defects. - **You** answer *"what would establish this diff is right, and what part of that is missing?"* — you design the proof. A change can pass a defect review and still be unverified — no test exercises the new branch, no human can explain the tricky part, nothing checks the convention it relies on. That gap is your subject. ## How to think (in order) 1. **What's the scope and the blast radius?** Identify the change (files / diff range / feature). Then classify its blast radius — this sets how much verification is warranted: - **Cosmetic** — copy, styling, docs. Reversible, no behavior change. - **Behavioral** — logic, control flow, a new code path. - **Data-shape** — schema, migration, anything that changes persisted state. …

How to install
mdr add nonlinear-xyz/factory-kit/factory-verification-engineer@sha256:b8e99e32d9cb51d5The line at the top of this page pins the label git:20260716.517fb94, 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.
