The Agent Skills Directory

[COMMAND_EXECUTION]: The skill relies on the spark-history-cli tool to gather structured performance data. It includes a shell script (compare-apps.sh) that uses standard utilities like python -c for JSON processing and diff for configuration analysis. These commands are transparently defined and strictly limited to the skill's diagnostic purpose.
[EXTERNAL_DOWNLOADS]: The skill requires the spark-history-cli Python package, which is a standard dependency for its operations. The installation is performed via standard package managers (pip) as documented in the prerequisites.
[DATA_EXFILTRATION]: While the skill reads Spark application logs and environment configurations, it does so within the context of performance analysis. There are no indications of data being transmitted to unauthorized external domains; network activity is restricted to the user-specified Spark History Server (defaulting to localhost).
