GAIP Listing Observer

There is only one tool, so there is no risk of confusing it with another operation. Its purpose is clearly stated: observe product listing data from public URLs.

The single tool name `gaip_observe_listing` follows a predictable snake_case verb_noun pattern with a clear server prefix. With only one name, there are no competing conventions to create inconsistency.

The server is a narrowly focused listing observer, so one tool is largely appropriate. However, a single tool is slightly thin compared to the typical 3–15 tool range, even if the scope justifies it.

The tool supports both single and batch URL observation and returns core listing data including price, stock, GTIN, variants, shipping, returns, platform agreement, and history. For a read-only observer with explicit exclusions, no obvious operational gaps are apparent.
