&lt;p&gt;Simon continues his exploration of LLM-assisted tool building by compiling an existing Go library into WebAssembly using Claude Fable 5. It&amp;rsquo;s a great example of using AI to rapidly prototype and compare different implementations of a small, sharp utility directly in the browser.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;&lt;a href="https://simonwillison.net/2026/Jul/16/mermaid-ascii/#atom-everything"&gt;Mermaid to ASCII art (mermaid-ascii)&lt;/a&gt;&lt;/strong&gt;
After recently building a Mermaid-to-ASCII tool using Grok Build&amp;rsquo;s Rust code, Simon discovered an older, more feature-rich Go library by AlexanderGrooff. To compare the two implementations, he used Claude Fable 5 to compile the Go version into WebAssembly. Notably, this newly ported tool also includes support for colors.&lt;/p&gt;</description></item></channel></rss>
