   Claude Code itself ships llms.txt files (docs.claude.com/llms.txt, code.claude.com/docs/llms.txt) confirming it is agent-oriented-docs-aware for its own product, and its agentic search/MCP tooling means it can fetch and consume arbitrary web docs including llms.txt if pointed at them via URL fetch or MCP.
