Executive Summary

Development Kit v0.8.0 introduces DKF Design Authority, an authoritative design system governance lifecycle capability designed to eliminate visual frontend drift across AI coding workflows. In projects with a user interface, design.md at the project root becomes the single authoritative source of truth for UI styling, token architecture, layout rules, spacing, typography, responsive behavior, and accessibility.

Key Highlights

1. Authoritative design.md Governance:

   • design.md is the single source of truth for visual UI.
   • Comprehensive 31-section specification structure generated from requirements or visual references.

2. /dk-design-system Command:

   • Dedicated command with 6 operational sub-modes (create, reference, existing, inspect, verify, amend).

3. Visual Reference Ingestion:

   • Analyzes screenshots, mockups, Figma exports, or existing UI to infer the reusable design system.
   • Categorizes decisions as Observed, Inferred, or Recommended.

4. Design System Preflight:

   • Mandatory DESIGN SYSTEM PRE-FLIGHT gate preventing unapproved UI execution in /dk-build, /dk-build-auto, and /dk-autopilot.

5. Same Design Team Test & Compliance:

   • Heuristic compliance checks in /dk-test.
   • Specialist Design Authority review pass in /dk-review issuing DS-xxx issue IDs and a gating Same Design Team Test: PASS | PARTIAL | FAIL verdict.

6. Controlled Change Management:

   • Strict 6-field DESIGN SYSTEM AMENDMENT PROPOSAL flow requiring explicit user approval before foundational changes to design.md.

7. Backward Compatibility & Non-Visual Exemption:

   • Pre-v0.8 projects with existing design.md are migrated non-destructively.
   • Non-visual and backend-only projects are completely exempt from design gates.
