Skanetrafiken Trip Planner

Security checks across malware telemetry and agentic risk

Overview

This skill behaves like a public transit trip planner and the reviewed scripts only query Skånetrafiken for locations and journeys.

Install only from a source you trust and make sure you are comfortable sending searched locations, coordinates, and intended travel times to Skånetrafiken. Avoid using exact home, work, or sensitive addresses if that privacy tradeoff is not acceptable.

Finding
The skill instructs the agent to execute local shell scripts (`./search-location.sh`, `./journey.sh`) and explicitly depends on `curl` and `jq`, which means it has shell execution capability despite not declaring permissions. Undeclared execution capability weakens trust boundaries and reviewability, because a host agent or user may believe the skill is documentation-only while it can invoke external commands and networked tooling.
