Nit – I rebuilt Git in Zig to save AI agents 71% on tokens
by fielding·Mar 26, 2026·23 points·34 comments
AI Analysis
●●●BangerBig BrainWizardry
71% token savings on git status by stripping human-readable fluff AI agents don't need.
Strengths
- •Real data from 3,156 coding sessions proves git wastes 7.4% of all shell command tokens.
- •Zero-cost Zig libgit2 interop with execvpe passthrough for unimplemented commands.
- •U1 diff context experiment validated across 27 trials with no comprehension loss.
Weaknesses
- •78 conformance tests still can't cover every git edge case from decades of development.
- •Benefits only AI agents; human developers lose familiar verbose output by default.
