Coding agents change which personal tools are worth attempting

Dan Luu argues that coding agents make some formerly impractical personal tool projects worth attempting, including custom search and Rust build experiments. He distinguishes a tool that works for his workload from a maintained product, and says implementation capability is advancing faster than autonomous verification. His examples support an argument about changing project costs, rather than a universal productivity or performance multiplier.

Why it matters

The essay helps engineers decide when a focused experiment is worthwhile and what evidence is needed before broadening it.

More context

The original page has no verified publication date. It also includes a counterargument about overfitting and maintenance: clearer pass-or-fail checks make a personal experiment easier to assess than a project with open-ended requirements.

Keep in mind

This is practitioner opinion with informal experiments, not a controlled benchmark. Success on the author’s workload does not establish general reliability or maintenance cost.
