The Agent Skills Directory

Command Execution: The skill operates by executing gcloud CLI commands via the Python subprocess module to gather diagnostic information and apply fixes.
scripts/quick_diagnose.py uses subprocess.run to call commands like gcloud filestore instances describe and gcloud logging read.
The implementation uses argument lists rather than shell strings, reducing the risk of command injection within the scripts themselves.
Indirect Prompt Injection Surface: The skill processes external data from Cloud Audit logs and Kubernetes (GKE) CSI driver logs, which are potentially influenced by actors in the cloud environment.
Ingestion points: Untrusted log data enters the agent context through the get_recent_audit_logs and get_client_csi_errors functions in scripts/quick_diagnose.py.
Boundary markers: The skill does not explicitly wrap ingested log content in delimiters meant to signal the agent to ignore embedded instructions.
Capability inventory: The skill possesses the ability to create VPC firewall rules and update Filestore instance configurations via the gcloud CLI.
Sanitization: The skill extracts information from JSON or text logs for reporting without specific sanitization of natural language content inside those fields.
Interactive Remediation Gate: To mitigate the risk of unauthorized modifications, the skill enforces a mandatory confirmation checkpoint before any destructive or corrective actions occur.
Instructions in SKILL.md explicitly require the agent to ask for user confirmation before calling the run_command tool for remediation.
The scripts/quick_diagnose.py script requires a specific --apply-fix flag to execute modification commands, preventing accidental execution during the diagnostic phase.
