Development Kit v0.8.0 — DKF Design Authority

Release Notes: Development Kit v0.8.0

Release Date: 2026-08-17
Release Target: Antigravity AI, OpenCode, and supported multi-platform coding environments
Target Package: development-kit@0.8.0
Status: Released

---

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.

Development Kit v0.7.0

What's Changed

• docs: lock v0.7 DK Intelligence and Control Center architecture by @eybersjp in #18
• feat: add DK Intelligence and Control Center by @eybersjp in #19

Development Kit v0.6.1

Development Kit v0.6.1 Release Notes (Proposed Release Candidate)

Overview

Development Kit v0.6.1 is a proposed maintenance and feature update that introduces Context-Aware Next-Step Guidance, hardens consequential action gating with fail-closed safety predicates, resolves standalone installer completeness by bundling the runtime/ subsystem, and adds comprehensive distribution verification tests.

Important

Status: Proposed v0.6.1 Release Candidate. Publication, tagging, and deployment remain strictly pending final human approval and clean-environment certification.

User-Visible Improvements

1. Context-Aware Suggested Next Step Guidance:
   • Completed Development Kit commands automatically compute and append a formatted ## Suggested Next Step(s) section to response markdown.
   • Intelligently recommends the single most logical next command based on completed tasks, lifecycle stage, verification state, outstanding human approval gates, and safety constraints.
2. CLI Bridge for Next-Step Calculations (scripts/next-step.mjs):
   • Enables CLI and script querying of next-step recommendations via --command, --stage, --context-json, --context-file, and --format=markdown|json.
3. Standalone Installer Completeness:
   • Standalone installation (npx development-kit init --all) now copies the runtime/ directory (runtime/autopilot and runtime/next-step), ensuring self-contained offline execution without repository fallback.
4. Expanded Skill Catalogue:
   • Total engineering skill count increased from 45 to 46 with the addition of next-step-guidance.

Safety Improvements

1. Fail-Closed Consequential /dk-ship Gating:
   • Recommending /dk-ship requires all 9 explicit positive conditions: success === true, approvalStatus === 'approved', verificationStatus === 'passed', testsStatus === 'passed', reviewStatus === 'passed', postSimplificationVerificationStatus === 'passed', empty blockers, empty outstandingApprovals, and non-automated mode (!isAutomated).
   • Absence, undefined, null, or unverified review status strictly fails closed.
2. Post-Simplification Regression Gate:
   • After /dk-simplify, the resolver recommends only /dk-test; /dk-ship is strictly prohibited immediately following simplification. Earlier test passes do not satisfy post-simplification verification.
3. Strict Input and Context Schema Validation:
   • CLI flags, JSON strings, and context files are strictly validated against canonical schemas before evaluation; invalid or malformed inputs exit safely with code 1.

Installation

Antigravity Global / Project

npx development-kit@0.6.1 init

OpenCode Integration

npx development-kit@0.6.1 init --opencode

Multi-Platform Adapters

npx development-kit@0.6.1 init --all-platforms

Upgrade Guidance

Projects upgrading from v0.6.0 or v0.5.2 can update project skills and configurations by running:

npx development-kit@0.6.1 init --force

Existing customized AGENTS.md and repository configurations are preserved unless explicitly overridden.

Compatibility

• Node.js: >=18.0.0 (Tested on Node.js 18, 20, and 22).
• Operating Systems: Windows (PowerShell/CMD), macOS, Linux (Ubuntu 24.04).
• Supported Hosts: Antigravity, OpenCode, Claude Code, Cursor, VS Code (GitHub Copilot), Cline, Windsurf.

Verification Evidence

All release quality gates pass cleanly across supported platforms:

• validate & skills:validate:test: Component structure, metadata, and CRLF/LF invariance verified.
• doctor & sync:validate:test: Plugin manifest and committed mirror synchronized.
• docs:validate & docs:validate:test: Documentation navigation, links, and version consistency verified.
• opencode:validate: Official schema-based opencode.json verified.
• platform:validate: Multi-platform adapter templates and CLI options verified.
• research:validate: Provider-neutral research trust boundaries and integration verified.
• next-step:test: 42 next-step unit, safety fail-closed, schema validation, and CLI tests passed.
• installer:validate:test: Standalone installation, runtime bundling, and distribution packaging verified.
• autopilot:test & evals:validate: 22 Autopilot runtime tests and 25 evaluation scenarios passed.

Known Limitations

1. Antigravity Plugin Manifest Versioning: plugin.json reports 0.1.0 reflecting the internal Antigravity plugin schema contract rather than the npm package version.
2. Sequential Task Discipline: Multi-task plans execute sequentially with individual subagent dispatches to prevent assumption drift.

Rollback Guidance

If rollback is required prior to public release:

git checkout v0.6.0

For installed projects, re-run npx development-kit@0.6.0 init --force.

Candidate Status

• Status: Release Candidate (Unreleased).
• Commit Authorization: Local commits f01bb35 and 24f53c7 created locally; release preparation commit pending review.
• Publication: NOT published, tagged, or pushed. Publication strictly requires explicit human authorization.
