SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the need for granular capability control within the Policy harness, preventing unauthorized expansion of system authority while allowing for safe, tested rule changes.

Core Features & Use Cases

  • Policy Authoring: Define and implement new task constraints, provider constraints, and tier limits.
  • Safety-First Implementation: Provides a structured runbook to test changes before they affect production systems.
  • Use Case: When a team needs to restrict access to a specific API route for a new user tier, this skill guides the operator through defining the constraint, verifying it with a boundary test, and deploying the rule safely.

Quick Start

Use the constraint-packs skill to define a new policy rule that restricts access to the sensitive data route for unauthorized users.

FAQPage Schema
How do I implement policy-based route controls for API security?

Policy-based route controls restrict unauthorized API access by defining task constraints and tier limits. You author these constraint packs within the Policy harness, validate changes through boundary testing, and deploy the rules safely to prevent unauthorized expansion of system authority.

What is the process for authoring task constraints and tier limits?

Authoring task constraints involves defining new provider rules and tier limits within the Policy harness. The skill provides a structured runbook to guide you through defining the constraint, verifying it with boundary tests, and safely implementing the route rules before production deployment.

Can I test policy rules and constraints before deploying to production?

Testing policy rules before deployment is supported through positive and boundary testing. The skill ensures all modifications to system boundaries are validated through a structured runbook, preventing unauthorized expansion of system authority while allowing safe rule changes.

Do I need the Policy harness to manage capability controls and constraint packs?

The Policy harness is required to manage the lifecycle of policy-based capability controls and constraint packs. It facilitates the definition, testing, and implementation of route rules, task constraints, and tier limits, ensuring granular control over system authority.

What are the limitations when modifying system boundaries with constraint packs?

Modifying system boundaries with constraint packs requires validation through positive and boundary testing before deployment. This safety-first approach ensures that all rule changes, task constraints, and tier limits are verified to prevent unauthorized expansion of system authority.
