SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps identify gaps in a module's existing specification by proposing invariants that the current documentation does not cover, enabling more comprehensive verification.

Core Features & Use Cases

  • Missing Invariant Detection: Analyzes module code and existing invariants to propose new properties that should be documented.
  • Scope Testing: Tests the completeness of specifications in safety-critical or complex software.
  • Use Case: For a module with documented invariants, generate proposals for invariants that could catch overlooked issues or edge cases, assisting developers in auditing and improving their specs.

Quick Start

Use the spec-adversary skill to analyze the queue module's invariants and suggest missing properties to improve robustness.

FAQPage Schema
How do I identify missing invariants in a module specification?

Missing invariant detection analyzes module code alongside existing specifications to propose new undocumented properties. This process requires code analysis and invariant comparison to generate robust proposals for undocumented gaps.

What is invariant analysis in software assurance workflows?

Invariant analysis in software assurance is a verification technique that identifies gaps in module specifications by proposing properties not currently documented. It supports validation efforts to ensure safety-critical modules have thorough specifications.

How do I test the completeness of specifications for safety-critical modules?

You test specification completeness by applying invariant analysis to safety-critical modules to generate proposals for new properties. This involves analyzing existing documented invariants to catch overlooked issues or edge cases in complex systems.

Can I use spec analysis for auditing module code and existing invariants?

Yes, spec analysis is designed for auditing module code and existing invariants. It compares the code implementation against documented properties to generate proposals for invariants that could catch overlooked issues.

When do I need formal verification for module completeness?

You need formal verification for module completeness when working with safety-critical modules and complex systems. It is required to ensure thorough invariants are documented and to support validation efforts in software assurance workflows.
