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.
- Plan a feature with evidence-based planning skills, then iterate on the plan
- Build the feature test-first with specialist implementation agents
- Run deep, adversarial code review on the resulting changes
Turns planning, implementation, review, and documentation work that would normally take a team into deterministic skills a solo engineer runs from Claude Code, with specialist agents doing the judgment-heavy work and folding findings into artifacts you can trust.
Solo product engineers and early-stage startups needing lightweight AI agents to handle async communication workflows.
