Old: `/ck-plan "my project"` - New: Say "create a project plan for..." - Reason: Antigravity IDE semantic triggering 2. **No Task Tool** - Old: Task tool for agent spawning/orchestration - New: Sequential/parallel skill invocation via user direction - Reason: Antigravity IDE native orchestration 3. **No Hooks** - Old: @prevent_execution, @privacy_prompt hooks - New: Hard-gate blocks in skill frontmatter - Reason: Antigravity IDE validation standard 4. **No ClaudeKit IDE Dependency** - Old: Required ClaudeKit IDE runtime - New: Requires Antigravity IDE v1.0+ - Benefit: Universal compatibility across platforms ### MIGRATION NOTES Users upgrading from ClaudeKit should: 1. Read `docs/migration-guide-from-claudekit.md` 2. Uninstall ClaudeKit skills (if desired) 3. Run `./install.sh --global` (Antigravity ClaudeKit) 4. Update project scripts that reference old skill names 5. Test `ck-planning` to verify installation ### KNOWN ISSUES - None (v1.0.0 is production-ready) ### FUTURE PLANS - [ ] v1.1.0: Add workflow visualization dashboard - [ ] v1.2.0: Real-time team collaboration features - [ ] v1.3.0: GitHub Actions integration for CI/CD - [ ] v2.0.0: Custom skill plugin system - [ ] v2.1.0: AI code generation (Claude API integration) --- ## Pre-Release History ### Development Phase: ClaudeKit → Antigravity ClaudeKit (Planning) **Key Milestones:** - [x] Skill conversion and validation - [x] Task/Hook dependency removal - [x] Documentation generation - [x] Installation system setup - [x] Quality assurance testing - [x] GitHub release preparation --- ## Version Schema This project follows [Semantic Versioning](https://semver.org/): - **MAJOR** version when making incompatible API changes - **MINOR** version when adding functionality in a backward-compatible manner - **PATCH** version when making backward-compatible bug fixes ## Commit Message Format This project follows [Conventional Commits](https://www.conventionalcommits.org/): ``` ():
