What problem does it solve? When the right shape or viability of a design is genuinely unknown and cannot be settled by reasoning alone, this Skill resolves the question empirically by building and comparing multiple throwaway prototypes instead of guessing. ## Core Features & Use Cases - Parallel spike tournaments: Dispatches clean-room, informed, and directed agents to build competing prototypes in isolated git worktrees, then eliminates dominated candidates while capturing lessons. - Adaptive tiers: Scales from a light single-round spike (2-4 variants) to a heavy multi-round tournament with independent reviewers and capstone synthesis. - Decision artifacts: Produces a findings document on a spike branch plus a standalone ADR on main with a cost-benefit verdict, including the valid outcome of not building at all. - Use Case: You are unsure which interface shape best fits a new subsystem. Run a spike tournament where three agents prototype different mechanisms, an independent reviewer verifies honesty of claims, and the result lands as an ADR recommending one design. ## Quick Start Ask the agent to spike three approaches to the design problem and compare them to pick a winner.
