anthropic-skills skill

“The reference pack, and it earns the title. Seventeen skills (the document formats docx, pdf, pptx, xlsx, plus builders like mcp-builder and skill-creator and the design skills), with an always-on cost of about 1,629 tokens, measured with tiktoken. The heaviest single description is xlsx at 238 tokens, fair for how much that one does; everything else is lean. Nothing here is a surprise, and that's the point of a reference implementation. This is what a well-built, well-scoped skill looks like, from the people who defined the format. Install the whole thing without worrying about the cost.”

context7 MCP server

“It does what it promises, fresh version-specific docs on demand, and the one thing to know is right there in how it works. context7 is a thin client for a hosted service, not a local tool. Both of its tools send your query text and the library name to context7.com over HTTPS; the docs corpus and the reranking live on Upstash's servers, so the task you're asking about leaves your machine. That's by design, not a leak, but if you work under an NDA that covers your prompts, treat it accordingly. Small tool surface (two tools), no filesystem access, no local data touched, and no telemetry beyond the API calls it exists to make. Free without a key (rate-limited by IP); an optional key raises the limit.”
