Self-Learning Skill Generator

Autonomously research and learn new technologies from the web, then generate a reusable skill.

Usage

/learn <topic>

If <topic> is missing, show usage. If topic is ambiguous, ask to clarify:

"react" → "React for web, React Native, or a specific library like react-query?"

"apollo" → "Apollo GraphQL client, Apollo Server, or Apollo Federation?"

"aws" → "Which AWS service? (S3, Lambda, DynamoDB, etc.)"

Normalize to kebab-case for filenames.

2. Discover Sources (Web Search)
Use web search tool to find authoritative documentation:

Search queries to try:

<topic> official documentation

<topic> getting started guide

<topic> API reference

<topic> GitHub repository

Source prioritization:

Official docs sites (e.g., docs.*, *.dev)

Official GitHub repositories (README, /docs)

Official blogs/announcements

Select 3–5 high-quality URLs maximum.

If no credible sources found, ask user to provide a URL.

3. Extract Content (URL Reading)

For each selected URL, read the content:

Extract only relevant sections:

Installation / setup

Core concepts

API reference / key functions

Common patterns / examples

Version information

Skip irrelevant content:

Navigation, ads, login prompts

Unrelated sidebar content

Comments, forums

If reading the content fails (JavaScript-heavy sites), fall back to browser agent:

Task: Navigate to <URL> and extract the main content including:
- Installation instructions
- Core concepts and API reference
- Code examples
Return the extracted content as markdown.

Record scrape timestamp for each source (use current date: YYYY-MM-DD format).

4. Generate Skill

Skills are modular, self-contained packages. Every skill consists of a required SKILL.md file and optional bundled resources:

skill-name/
├── SKILL.md (required)
│   ├── YAML frontmatter metadata (required)
│   │   ├── name: (required)
│   │   └── description: (required)
│   └── Markdown instructions (required)
└── Bundled Resources (optional)
    ├── scripts/          - Executable code (Python/Bash/etc.)
    ├── references/       - Documentation intended to be loaded into context as needed
    └── assets/           - Files used in output (templates, icons, fonts, etc.)

Read references/skill_creation_guide.md to understand the format and principles.

Synthesize the learned and extracted information into a new skill.

Trigger: Write a description that clearly defines when to use it.

Workflow: Create step-by-step instructions.

Format: Ensure valid YAML frontmatter and proper file structure.

5. Save the Skill

Antigravity supports two types of skills, save a global-workspace if asked.

.agent/skills/<skill-folder>/	Workspace-specific

~/.gemini/antigravity/skills/<skill-folder>/	Global (all workspaces)

Create directory if it doesn't exist, warn user before overwriting existing skill.

6. Confirm to User

Report:

✓ Created skill: <topic>
  Sources scraped: <N>
  Saved to: .agent/skills/<topic>/SKILL.md
  This skill will auto-trigger when working with <topic>.

Tool Reference

search_web: Discover documentation URLs

read_url_content: Extract content from static pages

browser_subagent: Extract content from JavaScript-heavy sites

write_to_file: Save the generated skill

Critical Rules

Never hallucinate documentation: Only include information from scraped sources.

Never invent APIs: If documentation is unclear, ask the user what to do.

Ask for URLs: If automated discovery fails, ask user for specific URLs.

Verify sources: Prefer official sources over third-party tutorials.
