policy-as-code-runner SKILL.md skillA
policy-as-code-runner from testland/qa is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add testland/qa/policy-as-code-runner@git:20261011.a1bd3f7Pins git:20261011.a1bd3f7 in mdr.lock. Pin the fingerprint instead.

Configures policy-as-code testing using OPA / Conftest / Cedar - authors policies in Rego (OPA's language), runs Conftest against Kubernetes manifests / Terraform plans / Dockerfiles / arbitrary structured data, integrates with CI for PR-time policy gates. Per OPA's docs: "an open source, general-purpose policy engine that unifies policy enforcement across the stack." Use to express + enforce custom policies (cost limits, tagging requirements, security baselines) that Checkov / tfsec / KICS…
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
# policy-as-code-runner
## Overview
[opa]: https://www.openpolicyagent.org/docs/
**Conftest** is a CLI that uses OPA ([opa-docs][opa]) to test
structured configuration files (Kubernetes manifests, Terraform
plans, Dockerfiles, etc.) against Rego policies. This skill
covers Conftest invocation + Rego policy authoring as the custom
policy layer alongside Checkov / tfsec / KICS (which carry
built-in checks).
## When to use
- The team has custom policies that off-the-shelf scanners
(Checkov / tfsec / KICS) don't cover (e.g., "all production
resources must have a cost-center tag").
- A Kubernetes admission policy is needed (OPA Gatekeeper).
- Dockerfiles need policy review (no `:latest` tags, no `apt-get
upgrade`, etc.).
- A multi-language IaC stack needs unified policy enforcement.
## Step 1 - Install Conftest
```bash
# macOS
brew install conftest
# Or download binary
curl -LO https://github.com/open-policy-agent/conftest/releases/latest/download/conftest_<version>_Linux_x86_64.tar.gz
```
## Step 2 - Author a policy in Rego
```rego
# policies/kubernetes/required_labels.rego
package main
# All pods must have these labels
required_labels := {"app", "version", "owner"}
…Read the whole file at its exact version.
How to install
mdr add testland/qa/policy-as-code-runner@sha256:9eda773776abfcd4The line at the top of this page pins the label git:20261011.a1bd3f7, 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.
