Expert system for creating Skills for the Antigravity agent environment. Generates complete `.agent/skills/` directories with SKILL.md files, helper scripts, examples, and resources following strict structural and writing standards. Use this skill whenever the user asks to build, generate, or scaffold a skill for Antigravity, mentions `.agent/skills/`, asks for a SKILL.md template, or wants to create agent capabilities using the Antigravity skill format. Also trigger when the user says things like 'build me a skill for X' or 'create an Antigravity skill' or references the Antigravity agent system.
Generate high-quality, predictable, and efficient .agent/skills/ directories for the Antigravity agent environment.
.agent/skills/ directory structureEvery skill must follow this folder hierarchy:
<skill-name>/
├── SKILL.md # Required: Main logic and instructions
├── brand_context.md # Recommended: Brand voice, tone, messaging guidelines
├── scripts/ # Optional: Helper scripts
├── examples/ # Recommended: Reference outputs showing target quality
└── resources/ # Optional: Templates or assets
Every skill that generates user-facing content (websites, copy, emails, social posts, documents) should include a brand_context.md file. This file tells the agent HOW to sound, not just WHAT to build.
A good brand_context.md covers:
When creating a skill, ask the user: "Does this skill generate content for a specific brand? If so, I'll create a brand_context.md to keep outputs on-brand."
The examples/ folder should contain reference outputs that show the target quality and style. These act as "gold standard" samples the agent can match against. Include:
The SKILL.md must start with YAML frontmatter:
testing-code, managing-databases). Max 64 chars. Lowercase, numbers, and hyphens only. Never include "claude" or "anthropic" in the name.Example:
