Generate, test, validate, explain, and debug OPA (Open Policy Agent) Rego policies and Conftest configurations. Covers deny/warn/violation rules, unit tests, regal linting, conftest fmt, namespace design, input shape analysis, and GitHub Actions integration. Use when asked to "write a policy", "test a rego file", "validate policies", "explain this rego", or "why is my policy not firing".
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
Write, test, validate, explain, and debug OPA Rego policies with Conftest. > **AI-agent behavior, not infra policy:** to gate what an AI coding agent (Copilot, Claude Code) can edit or run in a repo, use `/platform-skills:ai-governance` — a different policy engine for a different input shape (tool calls and diffs, not Terraform/Kubernetes manifests). --- ## Interactive Wizard (fires when no arguments are provided) When invoked with no arguments, ask before proceeding: **Q1 — Mode?** ``` What do you need? 1. generate — write a new production-ready Rego policy 2. test — write _test.rego unit tests for an existing policy 3. validate — run the full pipeline (fmt, lint, tests) against a directory 4. explain — translate an existing Rego policy into plain English 5. debug — diagnose why a policy is not firing as expected Enter 1–5 or mode name: ``` **Q2 — Context** (after mode selected, one at a time): - **generate**: `Describe the policy — target resource type (Terraform/Kubernetes/GHA/Dockerfile) and what to deny or warn on:` - **test**: `Paste the Rego policy to write tests for:` - **validate**: `Provide the directory path containing your .rego files:` …

How to install
mdr add nitinjain999/platform-skills/opa@sha256:9bb1413548f3ce2dThe line at the top of this page pins the label git:20261011.e8166a5, 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.
