Hey @hiroshinishio - I've reviewed your changes and found some issues that need to be addressed.

Blocking issues:

• Consider adding a condition to ensure pull request deployments only run on PRs from the same repository (link)

Overall Comments:

• Consider adding the dependency installation step for production deployments as well to maintain consistency between environments

Here's what I looked at during the review

• 🟢 General issues: all looks good
• 🔴 Security: 1 blocking issue
• 🟢 Testing: all looks good
• 🟢 Complexity: all looks good
• 🟢 Documentation: all looks good

🚨 suggestion (security): Consider adding a condition to ensure pull request deployments only run on PRs from the same repository

Pull requests from forks could potentially expose sensitive deployment credentials. Add 'if: github.event.pull_request.head.repo.full_name == github.repository' to the job level.
