I built a compiler that rewrites Python into a model-facing representation

The author released Vulpine, a compiler that converts Python into a compact model-facing representation for coding LLMs. Tests on about 13,000 held-out files showed roughly 14% token reduction and 99.8% AST-equivalent round-trip success, with code published on GitHub.

Why it matters: HKR-H/K/R all pass, with a named experiment and concrete numbers. Source authority is low and the post does not disclose real-task gains, speed, or failure cases, so it stays at the featured threshold.
