Full Summary
pwasm is a WebAssembly engine written entirely in Python, created during a period of intense interest in AI. Initially, it was a personal project that had not seen updates since January.
To enhance its capabilities, Claude Opus 5.5 was employed to evaluate and improve pwasm. The result was 42 commits that expanded its functionality to handle nearly all aspects of the WebAssembly specification.
It now successfully runs WASM builds of MicroPython, QuickJS, and Micro QuickJS from PyPI, a significant achievement for a project in its alpha stage. This development illustrates how AI models can effectively build upon previous work, leading to faster and more robust software solutions.
