Learning Levels

Level 1: Basics (15 min)

## What is CLAUDE.md?

A shared knowledge repository for the team. When Claude makes mistakes,
add rules to prevent the same mistakes from recurring.

## Example

# Development Workflow

## Package Management
- **Always use `pnpm`** (`npm`, `yarn` prohibited)

## Coding Conventions
- Prefer `type`, avoid `interface`
- **Never use `enum`** → Use string literal unions

## Prohibited
- ❌ No console.log (use logger)
- ❌ No any type

Level 2: Automation (30 min)

## What are Slash Commands?

Execute repetitive daily tasks with `/command-name`.

## Command Location

.claude/commands/{command-name}.md

## PostToolUse Hook

Auto-formatting after code modification:

// .claude/settings.local.json
{
  "hooks": {
    "PostToolUse": [{
      "matcher": "Write|Edit",
      "hooks": [{
        "type": "command",
        "command": "pnpm format || true"
      }]
    }]
  }
}

Level 3: Specialization (45 min)

## What are Sub-agents?

AI agents specialized for specific tasks.

## What are Skills?

Domain-specific expert context. Claude auto-references when working on related tasks.

## MCP Integration

Connect external tools (Slack, GitHub, Jira, etc.) via .mcp.json.

Level 4: Team Optimization (1 hour)

## PR Automation with GitHub Action

Mention @claude in PR comments to auto-update documentation.

## Team Rule Standardization

1. Manage CLAUDE.md with Git
2. Add rules during PR review
3. Gradually accumulate team knowledge

Level 5: PDCA Methodology

## What is PDCA?

Document-driven development methodology.

Plan → Design → Do → Check → Act
