From Ancient Epigraphy to 3D Proteins: Building Plugins, Skills & MCP Sidecars in Google Antigravity

Automated excerpt
Google Antigravity solves this at the runtime level with its Plugin & Customization Architecture - combining Progressive-Disclosure Skills (SKILL.md), Always-On Rules (AGENTS.md), Lifecycle Hooks (hooks.json), Zero-Leak Credential Protocols, and Dual-Process 3D MCP Sidecars (mcp_config.json + sidecar.json). Instead of just reading the docs, I reverse-engineered the newly released Google Antigravity Science Plugin (v1.3.1) and built the open-source Antigravity Science Plugin Cookbook & Interactive 3D Studio - complete with a live browser-based 3D Biomolecular & Variant WebGL Sandbox, a zero-dependency PEP 723 3D protein + PAE generator, and a production bio-structural-qc custom plugin.
