teamchong/pxpipe: Cut Claude Code token usage using image context rendering

pxpipe is a local proxy designed to reduce coding-agent input token costs by rendering bulky context such as system prompts and tool documentation into compact PNG images. By converting dense text into visual format, the tool achieves significant end-to-end bill reductions while relying on vision capabilities found in models like Gemini 4 and Claude Fable 5. However, the author notes that exact-string recall can be imperfect because model vision is not traditional OCR, and performance varies widely depending on the specific vision encoder used.
