While it creates new data in the system, it does not irreversibly destroy anything and does not execute arbitrary code or move money. From the tool's own definition: "Tool description states 'Upload a local file... to the Card Builder media directory' — this creates/adds a file to a destination directory, which is a write operation that modifies the media storage state." ## Use case AI agents use upload_media_from_path to create or update resources in Ha Nexus Agent, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ha Nexus Agent environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
