pi-openwiki

AI-powered documentation that stays current with your code

Automatically generates and maintains comprehensive documentation for your codebase using Pi's AI capabilities.

Based on OpenWiki by LangChain - adapted as a Pi coding agent extension.

Quick Start

# Install from npm
pi install npm:pi-openwiki

# Generate docs
cd your-project
pi
/openwiki:init

# Update after code changes
/openwiki:update

# Ask questions
/openwiki:chat How does authentication work?

What You Get

After running /openwiki:init:

openwiki/
├── quickstart.md              # Start here
├── architecture/              # System design
├── workflows/                 # Development processes
├── domain/                    # Business logic
├── operations/                # Deployment
└── testing/                   # Test strategies

Features

• 🤖 AI-Generated - Leverages your Pi model to understand your codebase
• 🔄 Git-Aware - Updates only what changed
• 🎯 Agent-Optimized - Works for humans and AI agents
• ⚡ Smart - Prevents redundant regeneration

Commands

/openwiki:init

Generate initial documentation for your repository.

/openwiki:update

Update docs based on git changes since last run.

/openwiki:chat <question>

Ask questions about your codebase without modifying docs.

Installation Options

# Global (use everywhere)
pi install npm:pi-openwiki

# Project-specific
pi install -l npm:pi-openwiki

# From GitHub
pi install git:github.com/barvhaim/pi-openwiki

# Temporary (this session only)
pi -e git:github.com/barvhaim/pi-openwiki

# Local development
pi -e /path/to/pi-openwiki

How It Works

1. Discovery - Explores your repository structure and git history
2. Analysis - Understands the "why" behind your code
3. Generation - Creates structured markdown documentation
4. Tracking - Saves metadata for smart incremental updates
5. Integration - Updates AGENTS.md/CLAUDE.md automatically

Requirements

• Pi >= 0.80.0
• Git repository
• Node.js with TypeScript

Package Gallery

This package is prepared for the Pi package gallery. It is ready to publish as pi-openwiki and declares the required Pi package metadata:

{
  "keywords": ["pi-package"],
  "pi": {
    "extensions": ["./extensions"]
  }
}

After publishing to npm, the package can be installed with:

pi install npm:pi-openwiki

Development

# Clone and install dependencies
git clone https://github.com/barvhaim/pi-openwiki.git
cd pi-openwiki
npm install

# Test locally
pi -e .

# Make changes and reload
/reload

Architecture

Modular design for maintainability:

extensions/openwiki/
├── commands.ts      # Command handlers
├── tools.ts         # AI tools
├── events.ts        # Event handlers
├── git-utils.ts     # Git operations
├── metadata.ts      # Metadata management
├── prompts.ts       # System prompts
└── constants.ts     # Constants & types

See extensions/openwiki/README.md for details.

Troubleshooting

"Not in a git repository!"
Initialize git: git init && git add . && git commit -m "init"

Commands not showing up?
Reload Pi: /reload

"No changes detected"
Normal - means your code hasn't changed since last update.
