gating SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

gating from oaustegard/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add oaustegard/claude-skills/gating@v0.3.0

Build and audit deterministic verification gates — a check that blocks a pipeline and can be shown to go red. Use when writing a calibration gate, CI check, validation script or pre-publication check for a numeric or empirical result; when a plausible-but-wrong value would survive review; when asking whether an existing test, linter rule or check could actually fail; and when a suite passes first try, passes suspiciously often, or was written by whatever produced the thing it checks. Triggers…

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

# gating

A gate is a check that blocks. Its only job is to go red when it should.

The characteristic failure is not a wrong check — a wrong check gets noticed.
It is a check that **cannot fail**, which reports PASS forever and is
indistinguishable from a working one from the outside. That is what makes this
different from ordinary testing: the object under suspicion is the check.

## When NOT to use this skill

Scope is ONE check and whether it can be made to fail.

| Situation | Use |
|---|---|
| Sequence several steps with branches and retries | flowing |
| Run the repo's existing suite | run it |
| Decide what to test at all | this skill has no opinion; that is design |

A gate is a thing that goes red. If nothing here can go red, there is no gate
to audit.

## The three obligations

Every gate owes these. A gate missing any of them is not yet a gate.

**1. An anchor outside your own code.** Something the check compares against
that your implementation did not produce: a published constant, a closed-form
answer, a conservation law, a degenerate case with a known result, an
independent implementation. A check that compares this run to the last run only
…

How to install

The exact contents, by fingerprint
mdr add oaustegard/claude-skills/gating@sha256:3fed62334d9eb61b

The line at the top of this page pins the label v0.3.0, 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.
