Overview

About This Skill

rego-skill automates the creation, security review, and testing of OPA Rego policies for authorization and access control. The skill guides you through a mandatory workflow: clarify requirements, generate policies with explicit default deny, create comprehensive tests covering allow and deny cases, validate with OPA CLI, and review against a security checklist. It supports modern OPA 1.0+ syntax (if/in/contains/every) and includes a suite-wide audit workflow that can scan entire policy corpora for vulnerabilities, cross-policy conflicts, and shadowed rules. Operations teams, platform engineers, and security practitioners use it to reduce authorization vulnerabilities and maintain consistent policy standards across their infrastructure.

How to Use

Clone the skill to your Claude skills directory or project. Install the OPA CLI and Claude Code CLI. The skill auto-activates when you mention OPA, Rego, authorization policies, or access control. Ask Claude to generate, review, or test policies—it will clarify requirements, write code, validate with opa check/test, and review against security checklist.

Use Cases

Generate role-based access control (RBAC) policies with allow/deny test coverage

Review existing OPA policies for security vulnerabilities and compliance gaps

Audit entire policy repositories against a security rubric in one pass

Create API gateway authorization policies with comprehensive edge-case testing

Usage Examples

Prompt Template

Create a new OPA Rego policy for [COMPANY] in the [INDUSTRY] sector. The policy should enforce [DATA] access controls. Include default deny rules and ensure compliance with [SPECIFIC_REGULATION]. Test the policy for vulnerabilities and suggest improvements.

Example Output

# OPA Rego Policy for [COMPANY] Data Access Controls

## Policy Overview
- **Purpose**: Enforce strict access controls for sensitive [DATA] in the [INDUSTRY] sector.
- **Regulation**: Compliant with [SPECIFIC_REGULATION].
- **Default Rule**: Deny all access by default.

## Policy Code
```rego
package example.authz

# Default deny rule
default allow = false

# Allow access based on role and data sensitivity
allow {
  input.role == "admin"
  input.data.sensitivity <= 3
}

# Allow access for specific roles and data types
allow {
  input.role == "analyst"
  input.data.type == "financial"
}
```

## Vulnerability Testing Results
- **Potential Issue**: Overly permissive role-based access.
- **Recommendation**: Implement attribute-based access control (ABAC) for finer granularity.
- **Suggested Improvement**: Add data classification checks to ensure compliance with [SPECIFIC_REGULATION].
