What problem does it solve? Functional requirements alone leave quality expectations ambiguous, causing AI development agents to invent performance, security, and availability targets. This Skill produces a signed, measurable NFR specification that downstream architecture, testing, security, and infrastructure phases can build against. ## Core Features & Use Cases - NFR Register Generation: Documents requirements across 8 categories (performance, security, availability, usability, reliability, maintainability, compatibility, compliance) with targets, thresholds, and verification methods. - Governed Sign-Off Workflow: Enforces prerequisite signature checks, validation rules, and a Solution Architect approval gate before the document is baselined. - Traceability & Sources Tracking: Maps each NFR to functional requirements and architecture components, and logs questions, gaps, and generation history in a sources file. - Use Case: After experience design is signed, run this Skill to produce documentation/04-requirements/nonfunctional-spec.md defining SLA targets, encryption standards, and WCAG compliance criteria that the test plan and security assessment will consume. ## Quick Start Ask the agent to generate the non-functional requirements specification for the current project once strategic intake, functional spec, and experience design are signed.
