nlspec

To translate product requests into testable acceptance criteria, you generate a precise NLSpec that defines scope, interfaces, constraints, and failure modes. This deterministic specification serves as a single source of truth for planner, coder, and QA teams to align on verifiable success criteria.

An NLSpec is a normative contract that translates intent into a deterministic specification used for implementation and validation. It governs software specification validation by specifying interfaces, dependencies, failure modes, and a verifiable Definition of Done to ensure complete testability.

To write deterministic specifications for end-to-end subsystems, you author an NLSpec that captures scope, contracts, and testable acceptance criteria. This provides a single source of truth ensuring planners, coders, and QA teams align on dependencies, assumptions, and verifiable outcomes.

You can apply natural language specifications to DSLs, engines, and end-to-end subsystems, not just standard modules. The NLSpec defines interfaces and constraints for these complex systems, handling explicit assumptions and open questions when evidence is missing.

The best way to document failure modes and constraints for technical requirements is generating a complete NLSpec. It converts user requests into a normative contract that explicitly defines dependencies, assumptions, constraints, and a verifiable Definition of Done.

You should not use a single source of truth specification like NLSpec for simple features lacking complex interfaces or verifiable acceptance criteria. It is designed for deterministic specs applied to end-to-end subsystems, engines, or DSLs where strict governance is required.
