What QA does

QA runs adversarial live testing against one committed revision using a setup worker, exactly n parallel test workers, and an aggregate pass. Use it to verify branch-built behavior with isolated reports and evidence.

QA is cataloged under Quality on DirSkills. QA comes from a repository tagged agent-harness, agent-orchestration, agent-skills, agentic-workflows and ai-agents.

Documentation

README

Excerpt

NAC quality assurance

Run adversarial, evidence-backed QA against one requested committed revision. Exercise the live branch-built server, not only unit tests. Preserve every worker's findings in independent ignored reports, then summarize the complete pass.

This workflow tests; it does not fix. Never edit source, dependency files, generated assets, repository configuration, issues, or pull requests during a QA pass.

Input and roles

n is the number of QA test workers. Accept one positive integer and default to 4. A caller-supplied value means exactly that many test workers, not a maximum or aspiration. Reject zero, negative, non-integer, or locally unsupportable values with concrete capacity evidence; never reduce n silently.

This is the opening of the README. Read the full README on GitHub.
