Score: 7.0/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 5)

NESH is a from-scratch UEFI shell written in C that reimplements the UEFI Shell command set and adds NESH BASIC, a scripting language for automation and boot management. It is a single ~363 KB nesh.efi binary with no EDK2 code, implementing EFI_SHELL_PROTOCOL 2.2, and it is Secure Boot aware. The project stands out for its self-contained implementation and integrated scripting, though real-hardware validation remains limited.

Target audience: firmware developers and power users working with UEFI systems
