Selection evidence
Confusable tool pairs.
3 pairs where similar names or overlapping descriptions may send an agent toward the wrong tool.
| Tool A | Tool B | Confidence | Why they collide |
|---|---|---|---|
get_top_vr_games |
get_top_vr_apps |
medium | Both are zero-arg 'VR.org's current ranked list of the top VR ___' tools differing only in games vs apps. Casual users routinely say 'best VR apps' while meaning games (and vice versa), so a query like 'what are the top VR apps to play' can be matched to either member. |
compare_vr_headsets |
vr_explain |
medium | A task like 'which headset should I buy' or 'compare the best VR headsets' straddles both: vr_explain returns the canonical 'best headset' pillar answer, while compare_vr_headsets gives a side-by-side. Without two explicit headset names, an agent can plausibly pick the wrong one. |
get_vr_trending |
get_top_vr_games |
low | A query such as 'what's trending in VR games right now' mixes the trending and ranked-top concepts; get_vr_trending returns feed topics while get_top_vr_games returns a ranked game list, so a combined wording can point an agent to either tool. |
