test-suite-curation

What problem does it solve?

This Skill helps teams safely reduce and reorganize large regression suites without losing meaningful coverage, by replacing intuition-based cleanup with evidence-based test analysis.

Core Features & Use Cases

• Coverage fingerprinting: Identifies exactly which lines and branches each test covers so you can see unique coverage and overlap.
• Duplicate and redundancy analysis: Clusters near-identical tests, compares execution profiles, and separates true redundancy from tests that only look similar.
• History-driven pruning and tiering: Mines CI results for never-failing or flaky tests, then helps classify tests into smoke, core, and extended tiers based on risk and defect-catch history.
• Safe removal workflow: Requires quarantine, human approval, observation windows, and a per-test audit log before any deletion is finalized.

Quick Start

Ask the assistant to audit your regression suite, find redundant or low-value tests, and produce a quarantine-first curation plan with an auditable deletion record.
