C2.9/5.0
Scored across 7 tools
Disambiguation2/5
Multiple tools have overlapping purposes that could cause confusion. 'latest_price_feeds', 'latest_price_updates', and 'timestamp_price_updates' all retrieve price updates by price feed ID with nearly identical descriptions, making them hard to distinguish. The deprecated tools add further ambiguity, though 'price_stream_sse_handler' and 'latest_publisher_stake_caps' are more distinct.
Naming Consistency3/5
The naming follows a mostly consistent snake_case pattern, but there are deviations in structure. Tools like 'latest_price_feeds' and 'price_feeds_metadata' use similar phrasing, while 'price_stream_sse_handler' includes 'handler' which breaks the pattern. The naming is readable but lacks a strict verb_noun convention, with some tools focusing on actions and others on resources.
Tool Count4/5
With 7 tools, the count is reasonable for a Pyth network data server, covering price updates, metadata, and streaming. However, the inclusion of deprecated tools ('latest_price_feeds' and 'price_feed_ids') slightly bloats the set, as they could be removed or consolidated to streamline the interface.
Completeness4/5
The tool set covers key aspects of the Pyth network domain well, including fetching price updates, metadata, publisher stake caps, and streaming. A minor gap exists in update or delete operations, but this is typical for a read-heavy data service. The deprecated tools suggest evolution but don't hinder core functionality.
