What hosting_cache_clear does on Hostinger
AI agents invoke hosting_cache_clear to trigger actions in Hostinger. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why hosting_cache_clear is rated High
Clearing a cache is an operational action that triggers an external side effect on the hosting infrastructure. It is not a simple read, and while it modifies the state of the cache, it is not a traditional write/create/update of persistent data. Cache clearing is an execution-type operation that affects website performance and behavior.
