factory-verification SKILL.md skillA
factory-verification from nonlinear-xyz/factory-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nonlinear-xyz/factory-kit/factory-verification@git:20260716.517fb94Pins git:20260716.517fb94 in mdr.lock. Pin the fingerprint instead.

How we know the software the factory produces is correct, and how we know the kit's own conventions are followed. Defines the four-tier eval spectrum (CLI rule / test / agent / human gate), the rule that evals graduate downward to their cheapest home, the banded coverage score with severity-aware disclosure, and the delta-gated GitHub Action that guards the PR boundary without disrupting the inner loop. The recipe locks to `factory-kit-check` + GitHub Actions; the principles are stack-agnostic.
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
# Factory verification Each section leads with **Principle** (one sentence, stack-agnostic), then **Why** (constraint → option → tradeoff), then **Recipe** (the `factory-kit-check` + GitHub Actions shape we use), and **Failure mode** when there's one to name. This skill answers a question the others assume: when an agent produces code, how do we know it's right — and how do we know the kit's own conventions were actually followed, not just documented? Scope is two layers: **L1**, verifying the software the factory ships; **L3**, verifying the factory's own conformance. Evaluating *shipped LLM features* (golden datasets, LLM-as-judge) is **L2** — a distinct problem, deferred; see the forward-pointer at the end. ## Verification is manufactured rigor **Principle.** When you unbundle production from comprehension — an agent produces, a human directs — you must deliberately re-add the verification that hand-writing every line used to bundle in for free. Code you didn't type is guilty until verified. …

How to install
mdr add nonlinear-xyz/factory-kit/factory-verification@sha256:ec2cf36a4688b8b1The 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.
