Citation Verification

The three tools cover clearly distinct purposes: cite_check verifies citation integrity, fact_check validates factual claims against authoritative sources, and source_freshness assesses liveness and recency. However, there is slight overlap between cite_check's URL resolution check and source_freshness's live check, which could occasionally confuse an agent. Overall, the descriptions are detailed enough to guide correct selection.

Two tools follow the noun+verb pattern (cite_check, fact_check), while source_freshness uses a noun+noun structure. This is a minor deviation from an otherwise consistent pattern. The names are still descriptive and unambiguous, so the inconsistency is not disruptive.

With only 3 tools, the server is tightly scoped to its stated purpose of citation verification. Each tool addresses a distinct aspect of the domain without redundancy, and the count feels appropriate for a specialized utility—neither too thin nor excessive.

The tool surface covers the essential operations for citation verification: checking whether citations resolve and match claims, validating factual claims against sources, and monitoring source freshness. Minor gaps exist, such as lacking a dedicated tool for retrieving full source content or checking DOI metadata in depth, but these are edge cases that agents can work around with existing tools.
