Fence

Keep AI in learning mode. Fence scans your code, figures out what you already know, and writes a CLAUDE.md file that instructs Claude to teach rather than just hand you answers.

How it works

1. Run Fence: Init in any project
2. Fence scans your code files and detects which patterns and skills you actually use
3. It writes a CLAUDE.md at the project root
4. Claude reads that file and adjusts — explaining concepts you're still learning instead of writing the code for you

Features

• Detects skills across 8 languages: JavaScript, TypeScript, React, Python, Go, Java, C#, Rust, Ruby, PHP
• Confidence scoring — distinguishes Expert from Familiar based on how often you use a pattern
• Accumulates knowledge across multiple projects (stored in ~/.fence/skills.json)
• Skills grouped by language in the generated CLAUDE.md

Usage

Open any project in VS Code and run the command:

• Command Palette (Ctrl+Shift+P): Fence: Init
• Keyboard shortcut: Ctrl+Shift+F (Mac: Cmd+Shift+F)

A CLAUDE.md file will be created or updated at your project root.

Example output

## What I Already Know
### TypeScript
- Async / Await (Expert)
- TypeScript Interfaces & Types (Proficient)

## What I'm Still Learning
### JavaScript/TypeScript
- Error Handling
- Promises

Claude will freely use skills you know, but will guide you through the ones you're still learning.

Requirements

• VS Code 1.115.0 or higher
• A project with source files (.ts, .js, .py, .go, .java, .cs, .rs, .rb, or .php)
