Scored across 4 tools
qr_code and host_file are clearly distinct, and page_to_markdown vs page_metadata differ by output (clean Markdown vs structured metadata/OG tags). The two page-fetching tools overlap in the fetch step and could be momentarily confused, but their return contracts are different enough to guide selection.
All names use snake_case (qr_code, page_to_markdown, page_metadata, host_file), which is consistent. The verb/noun style varies a bit (noun-only qr_code, noun_to_noun page_to_markdown, verb_noun host_file), but each name is readable and predictable.
Four tools is a compact, well-scoped set for a QR generation plus file-hosting/page-fetching utility. Slightly thin, but each tool earns its place and nothing looks redundant.
Generation (qr_code), fetching (page_to_markdown, page_metadata) and upload (host_file) are covered, but host_file returns a delete token with no corresponding delete tool, leaving a dead end for cleanup. No QR decoding or content-size/format management operations either.
