⚡ The 3 commands you'll build:
1. /pr — Reads git diff, writes PR title + description + test plan, pushes and creates PR on GitHub
2. /fix — Runs linter, fixes every error across all files, verifies zero errors remain
3. /explain — Reads entire project structure and writes complete architecture summary
🛠 How to create custom commands:
1. Create .claude/commands/ folder in your project
2. Add a markdown file (pr.md becomes /pr)
3. Write your prompt inside the file
4. Type the command in Claude Code — done
📁 Project commands: .claude/commands/ — shared with team via git
📁 Global commands: ~/.claude/commands/ — works in all projects
💡 Use $ARGUMENTS for dynamic input (e.g. /refactor src/utils.ts)
🎁 5 bonus commands:
• /deploy — tests, build, tag, GitHub release in one word
• /test — generate comprehensive tests for any function
• /review — code review without opening a PR
• /seed — realistic database seed data from your schema
• /morning — standup prep from git history
