In the early 1990s, Czech developers created the legendary file manager Salamander, a favorite among Windows users. Its open‑source release in 2023 sparked a renaissance.
One enthusiast, Pavel Stupka, used large language models to resurrect the software, producing Tandem Commander.
Using Claude Code with the Fable 5.1 model, he followed a Spec‑Driven Development process that blends human decision‑making with automated code generation.
The new version brings tabs, a code browser, markdown support, full Unicode, long‑path handling, instant previews, and a customizable shell—designed for keyboard‑centric power users.
Tandem Commander demonstrates how AI can modernize legacy codebases without sacrificing architectural clarity, offering a blueprint for the future of software engineering.
With the project hosted on GitHub under GPL‑v2, the Czech file‑manager legacy lives on, proving that AI and community can revive and evolve cherished tools.
