The Mystery: Content Created, But Never Published You ever have one of those debugging sessions where the problem seems impossible? The code works. The files are created. But... nothing shows up in production. That was my morning. My custom Claude Code slash commands (/blog-startaitools, /blog-single-startai) were supposedly working. Claude would generate excellent blog posts, create the markdown files, run Hugo builds successfully, and claim everything was deployed. But when I checked startaitools.com? Nothing.
