This is not accurate. The main agent typically uses a 1h cache (except for API customers, which can enable 1h but it is not on by default because it costs more). Sub-agents typically use a 5m cache.
Then my original question stands: why did this become an issue seemingly overnight if nothing changed?
So if I run a test suite or compile my rust program in a sub agent I’m going to get cache misses? Boo.
... so how do API users enable 1hr caching? I haven't found a setting anywhere.
