Added
- Native Antigravity (
agy) Support: Gemstack is now a first-class plugin for the Antigravity CLI.
- XML Role Architecture: Completely re-engineered all 9 expert roles using XML-structured instructions for higher stability and reasoning performance.
- Autonomous Subagents: Introduced
<subagent_capabilities> to all roles, enabling native delegation (e.g., SDET invoking Browser subagents).
- Artifact-Driven Workflows: Migrated the 5-step lifecycle to use native
agy artifacts (implementation_plan.md, task.md, walkthrough.md) for real-time progress tracking.
- Topologies v2.0:
- Backend: Added Drizzle ORM guardrails and N+1 query protection.
- Frontend: Added Next.js 15 Server Actions and Hydration Safety rules.
- Infrastructure: Added Proxmox/LXC specific resource limit guardrails.
- ML/AI: Implemented the AI Testing Pyramid and Multi-variable Circuit Breaker.
Changed
- Deprecated Manual Planning: Replaced
docs/plans/ with native agy artifacts in all workflows.
- Deprecated Status File: Migrated
.agent/STATUS.md to a persistent system artifact for faster cross-agent access.
