Show HN: Kosh – Bash shell runtime with 100x faster Shellcheck and LSP built-in

Kosh is a Bash-compatible runtime focused on VERY detailed diagnostics and performance.

The project started from frustration with how difficult shell errors can be to debug. And how slow some tools are.

The project is feature-complete and the core is usable enough to experiment with. There is a Language Server that works on shell scrips, but I'm planning to expand it to support every conf/YAML/etc file that may have Bash embedded in, e.g. GitHub workflows.

Report: bash incompatibility, broken diagnostics, cases where existing tools may solve the problem better

Thanks!
