Check Setup Progress

**Auto-run by AI:** Run `uv run python tools/setup_progress.py show` to display the current setup progress.

What You'll Do

| Item | Details | |------|---------| | Goal | Configure .gitignore and pre-commit hooks to prevent API key leaks. Safely complete Module 0 | | Duration | ~5 min | | Prerequisites | Lesson 0-1 through Lesson 0-4 completed; API keys configured in .env | | Course Page | Refer to [Course Materials Top](https://ai-agent.camp/en/course/module-0) in parallel |

> **Hint**: If the AI stops responding midway, type "please continue" or "it stopped" to resume.

Security Settings Auto-Setup

In this lesson, just run `/setup-security` and you're done. **No terminal operations required. The AI handles everything automatically.**

What the AI Does Automatically

1. Check `.gitignore` and auto-add missing entries (.env, credentials/, *.key, *.pem, etc.) 2. Auto-configure `pre-commit` hooks (block accidental commits of .env files) 3. Run a current safety check (verify .env is not tracked by Git, not committed in the past) 4. If issues are found, suggest auto-fixes

**AskQuestion settings:**

{
  "title": "Security Settings",
  "questions": [{
    "id": "action",
    "prompt": "Would you like to start the security setup?",
    "options": [
      {"id": "run", "label": "Start auto-setup (run /setup-security)"},
      {"id": "already_done", "label": "Security already configured"},
      {"id": "more_info", "label": "Why are security settings necessary?"},
      {"id": "different_lesson", "label": "Go to a different lesson"}
    ]
  }]
}

(run -> Run the contents of `/setup-security`) (already_done -> Go to completion check) (more_info -> Explain: "If API keys are exposed on GitHub, there is a risk of unauthorized use and high charges. This command automatically sets up preventive measures." Then prompt again.) (different_lesson -> Show module list)

Commands to Run

/setup-security

Expected Output Example

Security Setup Complete:
- .gitignore: Added .env, credentials/, *.key, *.pem ✓
- pre-commit hook: Configured ✓
- .env file: Not tracked by Git ✓

Common Troubleshooting

• pre-commit hook blocks a commit -> Ask the AI to "check the commit contents"
• .env is tracked by Git -> Ask the AI to "remove .env from Git tracking"

---

Checkpoint

• [ ] .gitignore includes .env
• [ ] .gitignore includes credentials/
• [ ] pre-commit hook is configured
• [ ] .env file is not tracked by Git
• [ ] Git history does not contain sensitive information

---

Module 0 Complete!

Once security settings are complete, Module 0 is fully done.

As a final check, run `/check-setup` to display a report of all items.

Next Steps

**AskQuestion settings:**

{
  "title": "Module 0 Complete! Choose Next Step",
  "questions": [{
    "id": "next_step",
    "prompt": "Congratulations! Module 0 is complete. What would you like to do next?",
    "options": [
      {"id": "start_lesson", "label": "Start the first lesson (/start-1-1: Banner Generation)"},
      {"id": "final_check", "label": "Run final check (/check-setup)"},
      {"id": "overview", "label": "Review the project overview (/overview)"},
      {"id": "finish", "label": "Finish here"}
    ]
  }]
}

(start_lesson -> Guide to /start-1-1) (final_check -> Run the contents of /check-setup) (overview -> Guide to /overview) (finish -> Display "Great work! You can start the first lesson anytime with /start-1-1")
