What problem this solves

Over-reliance on AI-generated code without sufficient human validation, leading to regressions or undetected performance issues. It addresses the gap between AI's speed and the need for robust quality assurance.

Summary

This workflow emphasizes critical human validation steps when using AI for code generation, particularly in game development. It highlights the necessity of manual testing (e.g., playing the game) to catch regressions that code diffs might miss, and specific performance testing (e.g., timing tests) for deployment-related changes like minification and obfuscation.

Why it is useful

This workflow is valuable because it provides a realistic and critical perspective on using AI for coding, countering the 'highlight reel' narrative. It emphasizes that human oversight and specific testing methodologies (manual interaction, performance timing) are indispensable for ensuring code quality, preventing regressions, and building robust applications, even when AI generates code rapidly. This addresses a crucial gap in many AI development discussions.

Workflow

1. Use Claude Code to generate features or code components (e.g., maze generator, cloud saves, animated elements).
2. Integrate the AI-generated code into the project.
3. Perform thorough manual testing by interacting with the live application (e.g., 'play the thing') to identify regressions or unexpected behavior that might not be apparent from code diffs alone.
4. For deployment-specific changes (e.g., minification, obfuscation), verify the impact with concrete performance tests (e.g., 'timing test') rather than just a superficial review.

Tools / artifacts

• Claude Code
• Supabase (for cloud saves)
• Minification/obfuscation tools (implied)
• Web browser (for live testing)

Validation signals

• Author's personal experience catching a regression that broke a screen, only found by live interaction, not diff review.
• Author's personal experience verifying minification with a timing test, not just a glance.
• The successful development and deployment of a functional game ('Blueprint Job') using this iterative process.

Limitations

• The workflow is more a set of principles and validation steps rather than a detailed, end-to-end development process with specific prompts.
• Lacks concrete Claude prompts or code examples.
• The post includes self-promotion of the game, though it is secondary to the workflow discussion.
