C2.3/5.0

Scored across 31 tools

Disambiguation1/5

Multiple tools have nearly identical purposes, such as browser-url-ok and playwright-url-ok both checking if a URL can be opened, and fetch-status, web-fetch, and citation all returning HTTP status for a URL. The boundaries between these and other checkers like normalize-url or lib-docs-hint are unclear, leading to frequent misselection.

Naming Consistency3/5

All names use lowercase kebab-case, which is a consistent style, but the semantic pattern varies widely: some are verb_object (fetch-status, validate-json), some are object_verb (domain-shape, memory-key-count), and others are single nouns (citation, timezone). The mixed conventions are still readable, but not predictable enough for a 4.

Tool Count2/5

With 31 tools, the server exceeds the 25+ threshold and feels heavy, especially since many tools overlap in function (multiple URL status/parse tools) or are trivial one-off checks. The large count dilutes the tool surface and suggests poor scoping for what appears to be a small utility server.

Completeness2/5

The tools repeatedly reference 'start_here.hop' as a required first step for the index tools, but no tool exists to fetch or handle that hop, leaving agents with a dead end. Additionally, the extensive set of URL status/check tools lacks any way to retrieve content or progress beyond checks, creating significant gaps for real workflows.
