I'm super confused as well. This seems like exactly that, just some default prompt injections to chose from. I guess I kinda understand them in the context of their claude chat UI product.

By I don't understand why it's a thing in Claude Code tho when we already have Claude.md? Could also just point to any .md file in the prompt as preamble but not even needed. https://www.anthropic.com/engineering/claude-code-best-pract...

That concept is also already perfectly specd in the MCP standard right? (Although not super used I think?) https://modelcontextprotocol.io/specification/2025-06-18/ser...

Claude.md gets read every time and eats context, while it sounds like the skills are read as-needed, saving context.
