get_flaky_tests Tests ranked by flakiness rate (failed+flaky / total runs)
get_test_history Full run history for a specific test — status, duration, error, retry, browser, OS
get_failure_patterns Failure rates broken down by browser × OS combination
get_slow_tests Tests ranked by average duration
get_error_groups Failures clustered by exact error prefix — surfaces shared root causes across tests
get_flakiness_trend Daily flakiness rate over the last N days — shows whether a test is getting worse
cluster_semantic_error_trees Like get_error_groups but normalises dynamic values (UUIDs, IDs, URLs) first, then fuzzy-merges with Levenshtein
correlate_git_commit_flakiness Finds the exact commit SHA where a test transitioned stable→flaky (or back), with branch and author
