Data Analysis Use Cases

These scenarios often involve chaining commands, using specific query syntax, and potentially combining the output with other tools or manual analysis.

CategoryNatural Language QueryCorresponding Tool(s)
Track a feature“Find all CLs with the topic ‘feature-x-implementation’.”query_changes
“List all files modified in CLs related to topic ‘performance-improvements’.”query_changes -> list_change_files (for each CL)
Analyze code churn“Show me all CLs by ‘user@example.com’ in the ‘analytics’ project merged last week.”query_changes
“Get the details for all changes in topic ‘refactor-backend’ and list the modified files and their change sizes.”query_changes -> list_change_files (for each CL)
Identify key contributors“Find the top 5 authors with the most merged CLs in the ‘data-pipeline’ project this month.” (Requires aggregation)query_changes -> Manual/External Aggregation
Audit changes“List all CLs merged to the ‘production’ branch between ‘2025-09-01’ and ‘2025-09-05’.”query_changes_by_date_and_filters
“Get the commit messages for all changes in CL set 12345, 12346, and 12347.”get_commit_message (multiple calls)
Correlate bugs with changes“Find all CLs that fix bugs in hotlist ‘critical-fixes’.” (Requires external bug tool to get IDs)External Tool -> query_changes
“For CLs 12300 to 12310, extract all mentioned bug IDs.”get_bugs_from_cl (multiple calls)
