self-learning
Autonomous skill generator that learns new technologies from the web. Use when, users want to learn about a new library/framework/tool, need to create a skill for an unfamiliar technology, want to research and document a technology's usage patterns, or invoke with `/learn <topic>`. This skill uses web search and browser tools to discover, extract, and synthesize documentation into a reusable skill.

- Gen Agent Trust Hubfail
This skill autonomously researches web content to generate new agent skills and executable scripts. It is highly vulnerable to remote code execution and indirect prompt injection because it processes untrusted data from the internet and converts it into executable code and agent instructions without sanitization.

What does this agent skill do?
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.mdto 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>.

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.
How can the creator link this skill?
Add the canonical catalog link to the repository README so users can inspect current installs and available audits. The publishing guide covers the complete discovery path.
