# CLAUDE.md

## Project Overview
This is a Next.js 14 app using TypeScript and Tailwind.

## Coding Standards
- Use functional components with hooks
- Prefer named exports over default exports
- Always use TypeScript strict mode

## Key Decisions
- We use Zustand for state management
- API routes are in /app/api

# Let Claude work for up to 10 turns without asking
claude --max-turns 10 "Refactor all components to use TypeScript strict mode"

# Good prompts for git operations
"Stage and commit these changes with a descriptive message"
"Create a PR for this feature branch to main"
"Show me the diff before committing"

# Claude will handle git commands and ask for approval

# Start with a plan
You: "Plan how we should implement user authentication with OAuth"

# Claude will outline the steps, files to create, and approach
# Then you can approve or adjust before implementation

/help     - Show all available commands
/clear    - Clear conversation history
/compact  - Summarize and compress context
/status   - Show current session status
/config   - View/edit configuration
/undo     - Undo last file change
/diff     - Show pending changes

    // Validate query is read-only
    if (!query.trim().toLowerCase().startsWith("select")) {
      throw new Error("Only SELECT queries allowed");

## Current Sprint
- [x] Setup authentication
- [ ] Add user profiles
- [ ] Implement dashboard

## Decisions Made
- Using Postgres for database
- JWT tokens for auth
- Tailwind for styling

## Blockers
- Waiting on API keys from client

# Great prompt for TDD
"Before implementing the user registration feature:
1. Write unit tests for the registration logic
2. Write integration tests for the API endpoint
3. Then implement the feature to make tests pass"

# Use the /project:infinite slash command
/project:infinite specs/my_spec.md output_dir 5

# This deploys 5 parallel agents to generate
# 5 unique iterations simultaneously

# In your conversation
"Update all API routes to use the new auth middleware.
You can work on multiple routes in parallel using task agents."

# Claude will spawn agents for independent route updates

# Run Claude Code without installing
npx @anthropic-ai/claude-code

# Or install globally for faster startup
npm install -g @anthropic-ai/claude-code

# In your shell config (.zshrc or .bashrc)
export CLAUDE_EDITOR=vim

# Or configure in settings
claude config set editor vim

# Add to your shell profile
export ANTHROPIC_API_KEY="sk-ant-..."

# Or use a .env file (add to .gitignore!)
echo "ANTHROPIC_API_KEY=sk-ant-..." >> .env
echo ".env" >> .gitignore
