What WIO does

WIO helps choose what to test next, write focused tests, generate realistic workloads, review test value, and diagnose test-suite health. Use it when you need a concrete testing workflow artifact rather than general QA advice.

WIO is cataloged under Quality on DirSkills. WIO comes from a repository tagged agent-skills, claude-skills, correctness, testing and verification.

Excerpt

WIO

WIO is one testing workflow skill with five command modes:

scan: find the highest-value test candidates for a codebase, change, or scope.
test: write one focused high-value test for a selected behavior, code path, or regression risk.
workload: generate a realistic, adversarial workload that adds a new failure surface, oracle, sequence, or coverage dimension with controlled variance, replay, and correctness invariants.
review: review a newly written or existing test for customer value, developer value, signal quality, and maintainability.
doctor: diagnose test-suite health problems in a codebase or scope.

Commands are accessed through $wio:
