🚀 Open-Sourcing Agent Skills v5.6.0 — Context Engineering & Multi-Agent Pack for AI Coding Assistants

• 182 Modular Skills (167 portable core + 15 stack/domain overlays) across 22 categories

• Native A2A 1.0 Protocol discovery & OWASP ASI01–ASI10 policy gates

• Out-of-the-box adapters for Google Antigravity, Claude Code, Cursor, OpenAI Codex, Copilot, Kiro & Windsurf
