What Grace Spec does

Grace Spec interviews the user to define a GRACE 4 GraceChangeSpec in .grace/changes/active/C-*/. It writes a draft spec.xml, can add optional design-context.xml, and waits for explicit approval before marking the spec approved.

Grace Spec is cataloged under AI Engineering on DirSkills. Grace Spec comes from a repository tagged agent-skills, ai-code-generation, ai-engineering, autonomous-agents and claude-code.
