The Agent Skills Directory

[INDIRECT_PROMPT_INJECTION]: The skill implements background tasks that ingest untrusted data from the device environment and external sources.
Ingestion points: The LOCATION_TASK in SKILL.md receives locations data from expo-location. The HeadlessTask receives taskData from the Android native layer.
Boundary markers: None. Code snippets do not include instructions to treat this data as untrusted or use delimiters when passing to an LLM.
Capability inventory: The skill uses syncToServer (Network egress) and saveLocations (Local file system write).
Sanitization: None. The provided templates do not demonstrate data validation or escaping before transmission or storage.
[COMMAND_EXECUTION]: The skill documentation includes an adb shell command (adb shell cmd jobscheduler run -f <package> <job-id>) for testing background jobs on Android. This is a standard developer diagnostic tool and is used here in an educational context for manual execution by the developer.
[EXTERNAL_DOWNLOADS]: The skill recommends installing official dependencies from well-known registries: expo-task-manager, expo-background-fetch, and expo-location via npm/npx, and workmanager via pub.dev. These are verified libraries from the Expo and Flutter ecosystems.
