Personal AI Infrastructure (PAI)

A skills-based context management system for Claude Code. PAI extends Claude Code with domain-specific knowledge, custom workflows, and automated session management - focused on automotive manufacturing operations.

What is PAI?

PAI is a personal AI infrastructure layer that sits on top of Claude Code, providing:

• Skills System - Modular context packages that load relevant knowledge on-demand
• Hook System - Event-driven automation for session lifecycle management
• Memory System - Session history, learnings, and signal capture
• Custom Commands - Slash commands for common workflows

This repository contains 38 automotive manufacturing skills covering IATF 16949 quality management, CNC operations, damper engineering, business operations, and plant management.

Prerequisites

• Claude Code CLI installed and authenticated
• Bun runtime (for hooks and tools)
• macOS or Linux (Windows via WSL)

Installation

1. Clone the repository

git clone https://github.com/robdtaylor/personal-ai-infrastructure.git ~/.claude

Note: If you already have a ~/.claude directory, back it up first:

mv ~/.claude ~/.claude-backup

2. Copy and configure settings

cd ~/.claude
cp settings.json.template settings.json

Edit settings.json to customize:

• Environment variables
• Hook configurations
• Permission settings

3. Install dependencies

# Install Bun if not already installed
curl -fsSL https://bun.sh/install | bash

# Install hook dependencies
cd ~/.claude/hooks && bun install

4. Verify installation

claude

You should see the PAI context load at session start.

Creating Custom Skills

Skills are modular context packages. Create a new skill:

mkdir -p ~/.claude/skills/MySkill

Create SKILL.md:

---
name: MySkill
description: Brief description. USE WHEN user says 'keyword1', 'keyword2'.
---

# MySkill

## Overview
What this skill does...

## Workflows
- WorkflowName: Description

## Reference
Key information the AI should know...

Regenerate the skill index:

bun run ~/.claude/tools/GenerateSkillIndex.ts

Hooks

PAI uses Claude Code's hook system for automation:

Hook	Purpose
SessionStart	Load core context, initialize session
PreToolUse	Security validation for Bash commands
PostToolUse	Capture signals and checkpoints
Stop	Capture learnings and session summary

Configure hooks in settings.json.

Custom Commands

Slash commands are defined in ~/.claude/commands/. Example:

# /mycommand

Description of what this command does.

## Instructions

Configuration

Environment Variables

Set in settings.json under env:

{
  "env": {
    "PAI_DIR": "$HOME/.claude",
    "TIME_ZONE": "Europe/London"
  }
}

Troubleshooting

Hooks not running

1. Check Bun is installed: bun --version
2. Verify hook paths in settings.json
3. Check hook file permissions: chmod +x ~/.claude/hooks/*.ts

Skills not loading

1. Regenerate skill index: bun run ~/.claude/tools/GenerateSkillIndex.ts
2. Check skill has valid YAML frontmatter in SKILL.md
