name: creating-skills description: Generates high-quality, predictable, and efficient .agent/skills/ directories based on user requirements. Use when the user wants to create a new skill or capability.

Antigravity Skill Creator

When to use this skill

• When the user says "create a skill for X"
• When the user provides instructions and says "turn this into a skill"
• When you need to define a reusable capability for the agent

Workflow

• Analyze Request: Identify the skill name (gerund), description, and core logic.
• Create Structure:
  • Create directory: .agent/skills/[skill-name]/
  • Create SKILL.md
• Draft Content:
  • YAML Frontmatter (strict adherence to standards)
  • Core Logic (concise, progressive disclosure)
  • Checklists and Validation instructions
• Review: Ensure folder hierarchy and best practices are met.

Instructions

1. Core Structural Requirements

Every skill you generate must follow this folder hierarchy:

• <skill-name>/
  • SKILL.md (Required: Main logic and instructions)
  • scripts/ (Optional: Helper scripts)
  • examples/ (Optional: Reference implementations)
  • resources/ (Optional: Templates or assets)

2. YAML Frontmatter Standards

The SKILL.md must start with YAML frontmatter following these strict rules:

• name: Gerund form (e.g., testing-code, managing-databases). Max 64 chars. Lowercase, numbers, and hyphens only. No "claude" or "anthropic".
• description: Written in third person. Must include specific triggers/keywords. Max 1024 chars. (e.g., "Extracts text from PDFs. Use when the user mentions document processing or PDF files.")

3. Writing Principles

When writing the body of SKILL.md, adhere to these best practices:

• Conciseness: Focus only on the unique logic of the skill.
• Progressive Disclosure: Keep SKILL.md under 500 lines. Link to secondary files for details.
• Forward Slashes: Always use / for paths, never \.
• Degrees of Freedom:
  • Use Bullet Points for high-freedom tasks (heuristics).
  • Use Code Blocks for medium-freedom (templates).
  • Use Specific Bash Commands for low-freedom (fragile operations).

4. Workflow & Feedback Loops

For complex tasks, include:

1. Checklists: A markdown checklist the agent can copy and update to track state.
2. Validation Loops: A "Plan-Validate-Execute" pattern.
3. Error Handling: Instructions for scripts should be "black boxes".

5. Output Template

When asked to create a skill, output the result in this format:

[Folder Name]

Path: .agent/skills/[skill-name]/

[SKILL.md]

---
name: [gerund-name]
description: [3rd-person description]
---

# [Skill Title]
