Could you build this?
No Nit is a systems-level Git replacement written in Zig with direct libgit2 C-bindings, custom diff context algorithms, process execution overrides, and low-level performance profiling.
What it would actually take: Building this requires deep systems programming expertise in Zig or C/Rust, understanding libgit2 internals and the git object database format directly on disk. You need to implement low-level diffing parsers, context-window optimizations (U1 hunk compression), zero-copy stdout streaming, and POSIX process replacement (`execvpe`) to maintain transparent backwards compatibility with Git CLI.
Discussion
20 comments analyzed.
Concerns raised: Misleading token savings claims - only ~5% of bash output, ~60 tokens per session, Didn't rebuild Git, only replaced small CLI portion of porcelain layer, Performance improvements (8ms vs 16ms) irrelevant compared to LLM inference time, Using Zig for CLI option handling is overkill for non-performance-critical code, Token savings achievable with existing Git settings (--short flag)
