AntiGravity Skill Creator
Create high-quality, predictable skills that extend agent capabilities.
When to Use
- •User asks to "create a skill" or "build an agent capability"
- •User wants to define specialized instructions for a task domain
- •User needs to standardize a repetitive workflow
Folder Structure
Every skill follows this hierarchy:
code
.agent/skills/<skill-name>/ ├── SKILL.md # Required: Main logic and instructions ├── scripts/ # Optional: Helper scripts ├── examples/ # Optional: Reference implementations └── resources/ # Optional: Templates or assets
YAML Frontmatter Standards
yaml
--- name: <gerund-name> # e.g., testing-code, managing-databases description: <3rd-person description with trigger keywords> ---
Rules:
- •
name: Gerund form, max 64 chars, lowercase + numbers + hyphens only - •
description: Third person, include trigger keywords, max 1024 chars
Writing Principles
- •Conciseness: Assume intelligence. Focus on unique logic, not explanations
- •Progressive Disclosure: Keep under 500 lines. Link to secondary files if needed
- •Forward Slashes: Always use
/for paths - •Degrees of Freedom:
- •Bullet points → High freedom (heuristics)
- •Code blocks → Medium freedom (templates)
- •Specific commands → Low freedom (fragile operations)
Workflow Patterns
Checklists
Provide markdown checklists the agent can copy and update:
markdown
- [ ] Step 1 - [ ] Step 2
Validation Loops
Use "Plan-Validate-Execute" pattern - verify before applying changes.
Error Handling
Scripts should be "black boxes" - instruct to run --help if unsure.
Output Template
When creating a skill, generate:
markdown
### [Folder Name] **Path:** `.agent/skills/[skill-name]/` ### SKILL.md --- name: [gerund-name] description: [3rd-person description with triggers] --- # [Skill Title] ## When to Use - [Trigger 1] - [Trigger 2] ## Workflow [Checklist or step-by-step guide] ## Instructions [Specific logic, code snippets, or rules] ## Resources - [Link to scripts/ or resources/ if applicable]
Supporting Files
If needed, also generate content for scripts/, examples/, or resources/.
