Show HN: StayLeet Helps Developers Keep Skills Sharp in the AI Coding Era

Summary

StayLeet is a small practice project created in response to a concern that developers may lose some coding-related judgment and technical fluency as AI writes more of their code. Its premise is that people still need enough knowledge to review and assess AI-generated output. The tool focuses on non-coding skills rather than maximizing lines of code, and currently offers two tracks: general technical fluency covering computer science, systems, and practical fundamentals, and system design. The author says the project was built primarily with AI tooling and is seeking feedback on whether on-the-job skill atrophy is a real concern, whether the tool is useful, and what alternative practices developers use.
