fathom_search_catalog — Search verified hardware and software by natural-language need — "laptop for running Llama 70B locally", "MCP server for GitHub", "noise cancelling headphones".
fathom_get_item — Fetch the complete verified record for a single product or software entry by slug, including the full editorial assessment and the date the data was last verified.
fathom_compare — Compare two or more items by slug, returning their specs, scores, pricing and stated trade-offs together so the differences are readable at a glance.
fathom_launch_radar — Check whether a successor or replacement is expected for a product line, so a recommendation is not made days before it is superseded.
