learn
Teach Claude ANY topic - code libraries, APIs, concepts, tools, methodologies, or domains. Researches via web and docs, then retains knowledge as a permanent skill. Use when user says "/learn ", "learn about X", "teach yourself Y", "become an expert on Z". Examples - "/learn stripe" for payments, "/learn GTD" for productivity, "/learn israeli-tax-law" for domain knowledge.

Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/aviz85/claude-skills-library --skill learn- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads learn automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Learn: Teach Claude Any Topic
Research and learn any topic, then retain the knowledge as a permanent skill. Works for:
- Code libraries: React, Stripe, Supabase (uses Context7 when available)
- APIs & Services: Twilio, OpenAI, Google APIs
- Concepts & Methodologies: GTD, Agile, Design Patterns
- Domain Knowledge: Tax law, medical terminology, industry practices
- Tools: Docker, Kubernetes, FFmpeg
After learning, Claude becomes an expert on that topic in all future conversations.
Usage
/learn <topic> # Create new skill from docs
/learn <topic> --update # Update existing skill with latest docs
/learn <topic> --project # Save to project (.claude/skills/) instead of global
Process
1. Research the Topic
For code libraries/APIs - try Context7 first:
mcp__plugin_context7_context7__resolve-library-id
query: "user's task/question"
libraryName: "<topic>"
For any topic (or if Context7 doesn't have it) - use WebSearch:
WebSearch: "<topic>" guide tutorial best practices
WebSearch: "<topic>" official documentation
WebSearch: "<topic>" examples patterns
For domain knowledge - broader research:
WebSearch: "<topic>" comprehensive guide
WebSearch: "<topic>" key concepts terminology
WebSearch: "<topic>" common mistakes pitfalls
Use WebFetch to read the most relevant pages found.
2. Extract Knowledge
Query the documentation for key information:
mcp__plugin_context7_context7__query-docs
libraryId: "<resolved-id>"
query: "getting started setup authentication common patterns"
Extract:
- Setup/Installation: How to get started
- Core concepts: Key abstractions and terminology
- Common patterns: Typical usage examples
- API reference: Essential methods/functions
- Gotchas: Non-obvious pitfalls mentioned in docs
- Best practices: Recommended approaches
If docs are large, make multiple targeted queries:
- "installation setup quickstart"
- "authentication API keys configuration"
- "common patterns examples"
- "error handling troubleshooting"
3. Consult Claude Code Guide
Before creating the skill, use the claude-code-guide agent to verify current skill conventions:
Task tool with subagent_type: claude-code-guide
prompt: "What are the current conventions for writing Claude Code skills?
I need to know: required/optional frontmatter fields,
description best practices, and recommended structure."
This ensures the generated skill follows the latest Claude Code patterns.
4. Generate Skill Structure
Create skill at appropriate location:
- Default:
~/.claude/skills/<topic>/skill.md - With
--project:.claude/skills/<topic>/skill.md
Skill template:
---
name: <topic>
description: <What the library does>. Use when <specific triggers>. Covers: <main capabilities>.
---
# <Topic> Quick Reference
## Setup
[Installation commands and initial config]
## Core Concepts
[Key abstractions - 2-3 sentences each]
## Common Patterns
### [Pattern 1 Name]
[Code example with brief explanation]
### [Pattern 2 Name]
[Code example with brief explanation]
## API Quick Reference
| Method | Purpose | Example |
|--------|---------|---------|
| ... | ... | ... |
## Gotchas
- [Non-obvious issue 1]
- [Non-obvious issue 2]
## Links
- [Official Docs](url)
- [API Reference](url)
5. Verify and Announce
After creating the skill:
- Confirm the skill was created
- Show the description (what triggers it)
- Show 2-3 example prompts that would activate it
Quality Guidelines
Do:
- Focus on practical, actionable information
- Include real code examples from docs
- Capture version-specific details if relevant
- Add the official docs URL for reference
Don't:
- Copy entire documentation (copyright)
- Include marketing/promotional content
- Add information Claude already knows generally
- Make the skill too long (under 500 lines)
Update Mode (--update)
When updating an existing skill:
- Read current skill content
- Query docs for latest/new information
- Merge new content, preserving existing structure
- Note version changes if applicable
Example
User: /learn stripe-payments
Claude:
1. Resolves "stripe" via Context7 → /stripe/stripe-node
2. Queries: setup, authentication, common patterns, webhooks
3. Consults claude-code-guide for current skill conventions
4. Creates ~/.claude/skills/stripe-payments/skill.md with:
- API key setup
- Payment intent flow
- Webhook verification
- Error handling patterns
5. Reports: "Created stripe-payments skill. Triggers on: 'Stripe payment', 'charge card', 'payment intent'"
Requirements
- Context7 MCP plugin (recommended) - for accessing library documentation
- OR WebSearch/WebFetch tools - as fallback for any documentation
FAQ
