What hippo_decay_run does on Verimem

AI agents invoke hippo_decay_run to trigger actions in Verimem. 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 hippo_decay_run is rated High

This tool triggers an algorithmic process (confidence-decay pass) that mutates state within the memory engine—specifically the confidence scores or decay metrics of prior stored facts. While the operation appears to be a maintenance/housekeeping function rather than arbitrary code execution, it still *executes* a side-effecting operation whose outcome depends on the state of memories and decay parameters.

From the tool's definition Tool name 'hippo_decay_run' with verb 'run' combined with description 'Run a confidence-decay pass' indicates execution of an internal operation that processes or modifies confidence metadata associated with stored memories.
