What problem does it solve?
Test suites often accumulate flaky, redundant, or low-value tests while leaving critical behavior unproven, making it hard to know whether a green build actually means anything. This Skill performs a read-only audit of an existing test portfolio to determine which important failures it detects, which evidence is untrustworthy or obsolete, and which additions, updates, merges, deletions, or explicit omissions produce the smallest sustainable portfolio.
Core Features & Use Cases
- Portfolio and Coverage Audit: Maps runners, suites, and test types, traces critical behavior (money, auth, data integrity, destructive operations) to tests with real oracles, and classifies every gap as KEEP, ADD, UPDATE, MERGE, DELETE, or NO_TEST.
- Isolation and Determinism Diagnosis: Detects shared-state leakage, order dependence, time and randomness sensitivity, and distinguishes test flakiness from genuine intermittent product defects using discriminating run matrices.
- Oracle and Structure Review: Flags assertion-free tests, weak truthiness checks, snapshot-only proof, mock contract drift, and fragile UI locators, then issues P0-P3 findings with verified practice references.
- Use Case: Before a major release, run the audit to learn that your payment retry logic has no failing-oracle test, three flaky suites share one global fixture, and forty snapshot tests prove nothing, then receive a prioritized remediation plan.
Quick Start
Ask the agent to audit this repository's test suite for coverage of critical behavior, flakiness, and weak assertions, and to return a verdict with prioritized portfolio actions.
