TfL London Transit
Security checks across malware telemetry and agentic risk
Overview
This skill appears to only fetch London transit information from the official TfL API, with no hidden execution, persistence, or unrelated data access found.
Reasonable to install if you want London TfL lookups. Be aware that journey searches, station names, coordinates, and the optional TFL_API_KEY may be sent to TfL; avoid putting unrelated secrets in the skill-local .env file.
