/cf-learn

The /cf-learn skill creates learning documentation from your coding sessions. It captures what you learned, insights gained, and techniques used. These docs can be hosted as a personal knowledge base or served via MCP.

Usage

/cf-learn [topic]

Or run without arguments to extract learnings from the current session.

What It Does

1. Analyzes Session — Reviews what you built and problems you solved
2. Extracts Insights — Identifies key learnings and techniques
3. Creates Docs — Generates clear learning materials with examples
4. Saves to Output — Stores in configurable directory (default: docs/learn/)
5. Enables Sharing — Docs can be hosted as website or served via MCP

Examples

/cf-learn TypeScript generics and constraints

/cf-learn async/await error handling patterns

# Auto-invoked after substantial new knowledge

Auto-Invocation

cf-learn activates automatically when you:

• Solve a complex technical problem
• Learn a new pattern or technique
• Overcome a major debugging challenge
• Complete a feature with novel architecture

Output Formats

Learning docs support multiple hosting options:

Website Hosting

cf host
# Serves docs/learn/ as a local website

MCP Server

cf mcp
# Exposes docs/learn/ via Model Context Protocol
# AI can reference while coding
