Suite of AI skills and agents from Test Double for solo product engineers and small teams. Combines evidence-based planning, test-driven implementation, documentation maintenance, deep code review, and architectural analysis into composable skills that dispatch specialist agents (project managers, adversarial reviewers, investigators, testing and security specialists). Ships as a parent plugin with bundled core, planning, coding, GitHub, and reporting plugins, plus opt-in Atlassian and Linear integrations.
