SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill ensures the scenario-level rules that must always hold are discovered, clarified, and enforced so that local development services remain dependable without regressing existing behavior.

Core Features & Use Cases

  • Domain intelligence: read docs/internal/INVARIANTS.md when available, study PRDs, requirements, and tests to understand the intended system rules.
  • Invariant articulation: name and describe each critical condition, distinguishing true invariants from incidental quirks before design or fixes proceed.
  • Enforcement and documentation: encode invariants through types, validations, runtime guards, or tests and log their status, enforcement, or gaps for future agents.
  • Use Case: When preparing a fix for the prompt manager scenario, use this Skill to confirm authentication, state shape, and lifecycle assumptions remain intact and fully documented.

Quick Start

Review scenario documentation, identify every invariant, and describe how it is enforced or where coverage is still needed.

FAQPage Schema
How do I discover and enforce system invariants to prevent code regressions?▼

Discover and enforce system invariants by reading documentation, analyzing code paths, and distinguishing true invariants from incidental quirks before encoding them through types, validations, runtime guards, or tests. This process prevents regressions across domain flows by maintaining consistent scenario-level rules.

What are system invariants in software engineering and when do they need documentation?▼

System invariants are critical conditions that must always hold true within domain flows. They require documentation when preparing fixes or updates, ensuring authentication, state shape, and lifecycle assumptions remain intact and fully logged for future agents to reference.

How do I document enforcement status for critical system rules in local services?▼

Document enforcement status by logging each critical rule's state, whether it is fully enforced through validations or tests, and identifying coverage gaps. Review requirements, PRDs, and tests to articulate and record the enforcement level for every invariant.

Can I use prompt manager scenarios to check authentication and state shape assumptions?▼

Yes, you can use prompt manager scenarios to confirm authentication, state shape, and lifecycle assumptions remain intact. The scenario focuses on invariant discovery and enforcement within local services to ensure development dependability without regressing behavior.

What is the best way to separate true invariants from incidental quirks before applying fixes?▼

The best way to separate true invariants from incidental quirks is to study PRDs, requirements, and tests alongside available internal documentation. Articulate each condition clearly, then encode and verify the true invariants through types, validations, and runtime guards.
