Expanso json-flatten
Security checks across malware telemetry and agentic risk
Overview
This skill is a small JSON parser with disclosed CLI and HTTP modes; the main caution is that its HTTP mode listens broadly by default and echoes submitted JSON back in the response.
Install is reasonable if you trust the Expanso runtime. Use CLI mode for sensitive JSON, or bind/firewall the HTTP mode so it is not exposed to untrusted networks; also verify the output fits your needs because it reports top-level JSON structure rather than producing a fully flattened dot-notation object.
