lift-and-constrain

What problem does it solve?

This Skill helps eliminate the regression cycle in rewrite-prone domains by inventorying, harvesting nuances, building test fixtures, and creating a canonical implementation with invariant constraints.

Core Features & Use Cases

• Inventory all Implementations: Analyze the entire codebase and history to gather every unique implementation and nuance.
• Nuance Harvesting: Extract all the input patterns, output mappings, and special cases from current and past implementations.
• Comprehensive Test Fixture: Build a JSON-formatted test fixture covering all the rules and scenarios, including negative cases.
• Canonical Implementation: Develop a single-source, high-quality implementation that meets all the fixture requirements.
• Continuous Testing: Run tests automatically on every commit to prevent future regressions.
