Groups failures by normalized error signature, deduplicates repeated errors, categorizes as assertion / timeout / network / crash. Pass customInfraPatterns for cloud-specific errors.
cross_reference_flakiness
Scores each failure against your flakiness history: KNOWN FLAKY, MILDLY FLAKY, or NO HISTORY.
correlate_code_changes
Matches changed files against failing tests. Works standalone or with pre-computed affected test lists from ast-impact-mapper-mcp.
generate_release_recommendation
The final step. Outputs a risk-weighted verdict with confidence score and full breakdown. Supports format: 'markdown' for GitHub PR comments and Slack.
detect_temporal_failure_patterns
Analyzes historical failures with timestamps to identify chronometric artifacts — failures that only appear at the same UTC hour, weekday, day of month, or during DST transitions.
analyze_rollback_readiness
Scans a repository for versioned migration files (Flyway V*.sql, Prisma migration.sql, Liquibase XML/YAML) and classifies each operation as additive (rollback safe) or destructive (forward-fix only).
