Delta specifications document additions, modifications, and removals for system changes. This skill generates them by identifying affected domains, reading current specs, and writing structured spec files with requirements and scenarios based on your proposals.

A delta spec outlines precise changes to requirements and scenarios for a system. You need one when a new feature is proposed or existing documentation requires updates, allowing you to highlight exactly what must be added or changed from current specs.

Generate testable requirements by writing scenario structures using Given/When/Then syntax alongside RFC 2119 keywords. This skill formats delta specifications to ensure clear, testable documentation for system changes across affected domains.

Yes, organizing specifications by affected system domains like auth or payments is supported. The skill identifies affected domains from your proposals and writes new or modified spec files structured accordingly to maintain clear domain-specific documentation.

Existing documentation is read to identify current requirements and generate accurate delta specs. The skill reads current spec files to determine exactly what needs to be added or modified, ensuring new documentation builds directly upon your established baseline.

The best way to document changes is generating delta specifications that clearly outline additions, modifications, and removals. This skill automates reading current specs and writing modified spec files in a structured format with RFC 2119 keyword adherence.
