Once that work is complete, the generated polling script automatically invokes `openclaw agent` and instructs a new agent execution to create a NotebookLM notebook, upload the report, and generate an audio overview. This downstream operation is not necessary to complete the research task and is not separately presented for user confirmation. The instruction changes the effective goal of the workflow from “research and save a report” to “upload the report to another service and create additional content.” The fallback to a direct notification reduces availability impact if the agent call fails, but it does not prevent the initial unauthorized invocation. ### Attack Path 1. A user requests Gemini Deep Research and approves the research parameters. 2. The Skill writes and launches the detached `poll.sh` process. 3. The research provider returns a completed result. 4. ...[truncated 1111 chars]- Remediation
