The two tools occupy clearly separate steps of one workflow: open_slates discovers slates and returns slateIds, while top_players consumes a slateId to return ranked players. Their descriptions explicitly cross-reference each other, so an agent cannot reasonably confuse them.

Both names are snake_case and read as action+resource, giving a predictable pattern. However, 'open_slates' is ambiguous between the verb 'open' and the adjective 'open' (unlocked), a minor departure from a clean verb_noun convention.

Two tools is thin even for a free-tier server; the surface is essentially one discovery call plus one detail call. It is defensibly scoped rather than padded, but leaves little room for the workflows the descriptions hint at (building lineups).

The slate-to-players path is covered end to end, but there are notable gaps: no player search, no position/salary filtering, no full pool, and no slate game detail beyond a count. Some gaps are deliberate free-tier limits, but agents will hit dead ends when asked about specific players or lineup construction data.
