What problem does it solve? Understanding how to tailor an AI agent's behavior across skills, rules, plugins, hooks, and MCP servers is confusing without a single reference covering discovery locations, loading priority, and configuration formats. This Skill consolidates the entire Antigravity Customization System into one guide so you can correctly create, register, and debug agent customizations. ## Core Features & Use Cases - Customization Type Selection: Compares rules, skills, plugins, hooks, and MCP servers side-by-side so you pick the right mechanism for your goal. - Discovery & Priority Reference: Documents workspace, hierarchical, and global discovery paths plus the five-level loading precedence that resolves naming conflicts. - Configuration Guides: Details hooks.json event contracts, mcp_config.json stdio/SSE transports, plugin.json manifests, and skills.json inheritance schemas. - Use Case: You want to enforce a lint check after every shell command the agent runs. Use this Skill to learn the PostToolUse hook contract, then write a hooks.json entry with a matcher and command script. ## Quick Start Ask the agent to explain how to create a new skill with a SKILL.md file and register it via skills.json for team sharing.
