Your SKILL.md Works in Claude Code but Silently Fails in VS Code

Not long ago, I had some issues getting my skills files from Claude Code to work in VS Code. No errors, no warnings. Just didn't see it. Turned out my name field said one thing while the parent directory was calling another. Claude Code doesn't mind this, but VS Code will not load it. Simple problem, but it wasted time than I'd prefer to admit. The Portability Problem Nobody Talks About Agent Skills (the SKILL.md format from agentskills.io ) are supposed to be write-once, run-anywhere. In practice, each agent has quirks: VS Code requires name to match the parent directory name exactly.
