well-006-url-metadata

There is only a single tool, so there is no possibility of misselection or overlap. Its purpose (fetch a URL's HTML head metadata) is stated explicitly and unambiguously.

With only one tool named 'url-metadata', there is no possibility of convention mismatch. The name is readable and accurately describes the resource it targets.

A single tool is thin by the general rubric, though it is arguably the right scope for a narrowly focused URL-metadata microservice. It covers exactly one operation, so there is no bloat but also no flexibility.

For its stated purpose the surface is essentially complete: it fetches a URL, follows redirects, extracts head metadata, and returns structured JSON with warnings. Minor gaps exist (no header/auth options, no batch fetch), but agents can work around them.
