There is only one tool, so there is no possibility of tool confusion or misselection. Its purpose—Perplexity-powered web search with recency filtering—is clearly stated.
The name perplexity_search_web follows a clear, descriptive snake_case verb_noun pattern. Though only one name exists, it is unambiguous and predictable.
A single tool is thin for a server whose underlying API (Perplexity) supports broader interactions. It is focused rather than trivial, but agents have no fallback or complementary operation.
Search with recency filtering covers the core use case, but there is no option for chat completions, domain/date range controls beyond recency, or result-format variations. Agents needing anything beyond a basic search hit a dead end.
