Start the History Server:

$SPARK_HOME/sbin/start-history-server.sh

Installation

cd spark-history-cli
pip install -e .

Or install from PyPI:

pip install spark-history-cli

Install as a Copilot CLI skill

spark-history-cli install-skill

If Copilot CLI is already running, reload skills with:

/skills reload

Then verify with /skills list and invoke it with prompts like:

Use /spark-history-cli to inspect the latest completed SHS application.
