Setup Project

Setup Claude Code Configuration

Analyze the current project and create comprehensive Claude Code configuration including CLAUDE.md, rules, slash commands, agents, skills, hooks, and RALPH autonomous development setup.

Overview

This skill performs intelligent project setup by:

1. Deep Project Analysis - Scans codebase for language, framework, patterns, conventions
2. Claude Code Configuration - Creates CLAUDE.md, rules, commands, agents, skills, hooks
3. RALPH Integration - Sets up autonomous development with intelligent PRD generation
4. PROJECT_SPEC.md - Generates comprehensive project documentation for RALPH context

Execution Flow

Phase 1: Project Analysis

First, thoroughly explore the codebase to understand:

# Check for manifest files to determine tech stack
ls -la package.json tsconfig.json pyproject.toml go.mod Cargo.toml *.csproj 2>/dev/null

# Check for existing Claude configuration
ls -la .claude/ CLAUDE.md 2>/dev/null

# Get project structure overview
find . -maxdepth 2 -type d ! -path './node_modules*' ! -path './.git*' 2>/dev/null | head -30

Analyze:

• Language: TypeScript, JavaScript, Python, Go, Rust, C#
• Framework: React, Next.js, Vue, Express, FastAPI, Django, NestJS, etc.
• Package Manager: npm, yarn, pnpm, bun, pip, cargo, go mod
• Test Framework: Vitest, Jest, Mocha, Pytest, Go test
• Linting: ESLint, Biome, Prettier, Ruff
• Type System: TypeScript strict mode, Python type hints
• Build System: Vite, Webpack, esbuild, Turbopack

Phase 2: Create Directory Structure

mkdir -p .claude/rules .claude/commands .claude/agents .claude/skills .claude/hooks
mkdir -p scripts/ralph tasks

Phase 3: Generate CLAUDE.md

Create a comprehensive CLAUDE.md based on analysis:

# Project: [Name]

[One-line description from package.json/README]

## Architecture Overview

[Directory tree - 3 levels deep]

## Tech Stack

| Layer | Technology |
|-------|------------|
| Language | [Detected language] |
| Framework | [Detected framework] |
| Runtime | [Node.js version / Python version] |
| Package Manager | [npm/yarn/pnpm/pip/cargo] |
| Test Framework | [Vitest/Jest/Pytest] |
| Linting | [ESLint/Biome/Ruff] |

## Development Commands

| Command | Description |
|---------|-------------|
| `[dev command]` | Start development server |
| `[build command]` | Build for production |
| `[test command]` | Run tests |
| `[lint command]` | Run linter |
| `[typecheck command]` | Type checking |

## Key Patterns

[Document discovered patterns:]
- Module system (ES modules / CommonJS)
- Naming conventions (camelCase / kebab-case / PascalCase)
- Import order (Node builtins → External → Local)
- Testing patterns (test location, naming)
- Type usage (strict TypeScript, Python type hints)

## Code Style Quick Reference

[Language-specific conventions discovered]

## Important Files

| File | Purpose |
|------|---------|
| [entry point] | Application entry |
| [main config] | Configuration |
| [key modules] | Core functionality |

## Environment Variables

[List from .env.example or detected - NEVER values, only names]

## Files to Avoid Reading

node_modules/ dist/ build/ .next/ coverage/ pycache/ .log .env .env.

## Summary Instructions

When compacting context, prioritize:
1. Current task progress and remaining steps
2. Recent code changes and their purpose
3. Error messages and their solutions
4. API contracts and data models

Deprioritize:
1. Full file contents after initial read
2. Build output and compiler messages
3. Large dependency listings

Phase 4: Create Style Rules (.claude/rules/)

Based on detected tech stack, create appropriate rule files:

For TypeScript/JavaScript:

typescript-style.md or javascript-style.md:

• Import/export conventions
• Async/await patterns
• Error handling approach
• File operation libraries (fs-extra vs native fs)
• Path handling (path.join vs string concatenation)

For Python:

python-style.md:

• Type hints requirements
• Async patterns (asyncio)
• Virtual environment expectations
• Import organization

For Go:

go-style.md:

• Error handling (explicit returns)
• Package organization
• Interface usage
• Concurrency patterns

Always create:

security.md:

• Sensitive file patterns to avoid
• Environment variable handling
• Input validation requirements
• Authentication patterns

code-style.md:

• Naming conventions
• Indentation (2 spaces / 4 spaces / tabs)
• Line length limits
• Comment expectations

Phase 5: Create Slash Commands (.claude/commands/)

Create commands based on project needs:

commit.md - Git commit helper review.md - Code review checklist test.md - Run tests with coverage deploy.md - Deployment automation (if applicable) ralph.md - RALPH status and control ralph-run.md - Run RALPH autonomous agent

Phase 6: Create Custom Agents (.claude/agents/)

code-reviewer.md - Expert code review debugger.md - Debugging specialist researcher.md - Codebase exploration

Phase 7: Create Skills (.claude/skills/)

code-review/SKILL.md - Code review skill prd/SKILL.md - PRD generation skill ralph/SKILL.md - PRD to JSON conversion ralph-run/SKILL.md - RALPH execution

Phase 8: Configure Hooks (.claude/hooks/)

hooks.json:

{
  "hooks": {
    "PostToolUse": [{
      "matcher": "Write|Edit",
      "hooks": [{
        "type": "command",
        "command": "[lint command]",
        "timeout": 30000
      }]
    }],
    "Stop": [{
      "matcher": ".*",
      "hooks": [{
        "type": "command",
        "command": "${CLAUDE_PROJECT_DIR}/.claude/hooks/auto-compact.sh",
        "timeout": 5000
      }]
    }]
  }
}

auto-compact.sh - Context usage monitoring (warns at 70%)

Phase 9: Configure Settings (.claude/settings.json)

{
  "permissions": {
    "allow": [
      "Bash(npm:*)",
      "Bash(npx:*)",
      "Bash(node:*)",
      "Bash(git:*)",
      "Bash([test runner]:*)",
      "Bash(mkdir:*)",
      "Bash(chmod:*)",
      "Bash(ls:*)",
      "Bash(rm:*)",
      "Bash(cp:*)",
      "Bash(mv:*)"
    ],
    "deny": [
      "Read(.env)",
      "Read(.env.*)",
      "Read(./secrets/**)",
      "Read(**/*.pem)",
      "Read(**/*.key)",
      "Read(**/credentials*)",
      "Read(node_modules/**)",
      "Read(coverage/**)"
    ]
  }
}

Phase 10: RALPH Autonomous Development Setup

10a: Generate PROJECT_SPEC.md

Create comprehensive project specification:

# Project Specification: [Name]

> Generated: [Date]
> Analyzed by: claude-init

## Overview
[From README/package.json]

## Tech Stack
[Full technology breakdown]

## Directory Structure
[3-level tree]

## Dependencies
### Production
[Top 15 with purposes]

### Development
[Top 10 with purposes]

## Available Scripts
[All npm scripts / Makefile targets]

## Code Patterns & Conventions
### Testing
- Framework, location, coverage config

### Type System
- Language, strict mode

### Code Style
- Naming, module system, linting, formatting, import order

## Codebase Patterns for RALPH
[Discovered patterns as bullet list]

## Quality Gates
```bash
# Commands RALPH must run before marking stories complete
[typecheck command]
[lint command]
[test command]

#### 10b: Create scripts/ralph/

**ralph.sh** - Bash loop that runs Claude iterations:
```bash
#!/bin/bash
MAX_ITERATIONS="${1:-10}"
ITERATION=0
while [ $ITERATION -lt $MAX_ITERATIONS ]; do
  ITERATION=$((ITERATION + 1))
  echo "=== RALPH Iteration $ITERATION/$MAX_ITERATIONS ==="

  # Run Claude with RALPH prompt
  claude --dangerously-skip-permissions \
    -p "$(cat scripts/ralph/CLAUDE.md)" \
    --allowedTools 'Bash(git:*),Bash(npm:*),Read,Write,Edit,Grep,Glob'

  # Check for completion signal
  if grep -q "COMPLETE" progress.txt 2>/dev/null; then
    echo "✓ All stories complete!"
    break
  fi
done

CLAUDE.md - RALPH system prompt with:

• Mission: One story per iteration
• Context sources: prd.json, PROJECT_SPEC.md, progress.txt, git history
• Quality gates: typecheck, lint, test
• Commit format: feat: [Story-ID] - [Story Title]
• Exit signal: <promise>COMPLETE</promise>
• Project-specific context from analysis

10c: Create Initial PRD (if feature provided)

If user provides --feature "description":

1. Generate intelligent prd.json based on:

   • Feature description
   • Tech stack (React UI, Backend API, etc.)
   • Existing patterns (TypeScript, test framework, linting)

2. Create appropriately-sized user stories:

   • Priority 1: Data models/types
   • Priority 2: Core logic/services
   • Priority 3: API/routes
   • Priority 4: UI components
   • Priority 5: Polish/tests

3. Initialize progress.txt with discovered patterns

4. Create tasks/prd-[feature].md markdown version

Phase 11: Output Summary

After completion, display:

cat PROJECT_SPEC.md

# 3. Start RALPH autonomous development
./scripts/ralph/ralph.sh 20

# 4. Monitor progress
tail -f progress.txt
cat prd.json | jq '.userStories[] | {id, title, passes}'

# 5. When complete, review and merge
git log --oneline -20
git diff main...HEAD

Interactive Mode

When run without --yes, prompt for:

1. Project name confirmation
2. Language/framework verification
3. Commands to enable (hooks, agents, commands, rules, skills)
4. RALPH setup preference
5. Initial feature description (optional)

Command Line Options

/setup-project [options]
  -t, --target <path>     Target directory (default: current)
  -y, --yes               Skip prompts, use defaults
  -m, --merge             Merge with existing config

  --no-skills             Skip skills setup
  --no-ralph              Skip RALPH setup

Quality Assurance

Before completing setup, verify:

• CLAUDE.md accurately describes the project
• PROJECT_SPEC.md has correct tech stack
• Rules match detected language/framework
• Commands use correct package manager
• Hooks reference correct lint/test commands
• Settings.json has appropriate permissions
• RALPH scripts are executable (chmod +x)
• PRD stories (if created) are appropriately sized
